A volcano in the central Philippines became active briefly on Tuesday, releasing a plume of ash and debris 4 kilometres (2.4 miles) high into the sky. This prompted authorities to cancel classes in four nearby villages affected by ashfall, officials confirmed. According to the Philippine Institute of Volcanology and Seismology, Mount Kanlaon’s early-morning eruption lasted for over an hour. Ash reached at least four agricultural villages to the southwest of the volcano on Negros island. No injuries or property damage were reported. Volcano erupts in southwestern Iceland after a nearby town and spa are evacuated The volcano had previously erupted in December, leading to the evacuation of thousands. Many of those displaced residents remained in temporary shelters on Tuesday, as Kanlaon continued to display signs of unrest, the Office of Civil Defense reported. Teresito Bacolcol, the Philippines’ chief volcanologist, told The Associated Press that there were no significant new indicators of heightened volcanic activity—such as an increase in volcanic earthquakes—that would necessitate raising the alert level from its current level 3, which indicates a “high level of volcanic unrest.” The highest alert, level 5, would signal that a “hazardous eruption is in progress.” “There’s always a chance of a larger eruption,” Bacolcol said, advising the public to remain alert and to avoid the 6-kilometre (3.7-mile) permanent danger zone around the volcano. Mount Kanlaon stands 2,435 metres (7,988 feet) tall and is among the Philippines’ 24 most active volcanoes. In 1996, three hikers died and several others were rescued after an unexpected eruption near the summit, officials recalled. Hawaii’s Kilauea volcano erupts displaying stunning lava fountains The Philippines lies along the Pacific “Ring of Fire,” a zone known for frequent earthquakes and volcanic eruptions. The country also experiences around 20 typhoons and storms annually, making it one of the most disaster-prone regions globally.

Firefighters managed to halt the forward spread of a wildfire sweeping through a remote region of eastern California, yet evacuation orders for residents of hundreds of homes remained in effect, officials reported Monday evening. The Silver Fire ignited Sunday afternoon along Route 6 in Inyo County, approximately 5 miles (8 kilometers) northeast of Bishop in the Owens Valley, near the Nevada border. Authorities were investigating the cause. AI-enabled drone deployed in Germany to accelerate wildfire detection and response By Monday, the fire had scorched nearly 2.5 square miles (about 6.5 square kilometers) of grass and brush, according to a post on the social platform X by the California Department of Forestry and Fire Protection. Containment had reached 47%. Following the outbreak, evacuation orders were issued for around 800 homes near the small communities of Laws, Chalfant, and White Mountain Estates. However, officials did not provide an update Monday evening on how many residents remained under evacuation orders. Fire crews planned to stay overnight to monitor hotspots and reinforce containment lines. Gusts reaching 65 mph (104 kph) had restricted the deployment of water-dropping helicopters and kept air tankers grounded, Cal Fire spokesperson Chloe Castillo said earlier on Monday. “The winds are highly unpredictable,” she noted. “At one moment, they push north; the next, they shift east.” Cal Fire reported that the fire threatened land belonging to the Bishop Paiute Tribe, as well as habitats of endangered species such as the Owens pupfish and desert bighorn sheep. Inyo County has experienced minimal recent rainfall and remains unusually dry, with some areas suffering from extreme drought. South Korea battles devastating wildfires as death toll reaches 27 Similarly, much of Southern California is facing moderate to extreme drought conditions, according to the U.S. Drought Monitor.

One person has died, and several others have been injured as a tropical low moves west across the Australian east coast, reports AP. Heavy rainfall is expected to continue battering parts of the Australian east coast for several more days, despite the region escaping the destructive winds of its first tropical cyclone in 51 years, officials said on Saturday. Authorities confirmed one fatality and multiple injuries. Evacuations ordered as first cyclone in 51 years approaches Australia Tropical Cyclone Alfred was initially predicted to be the first cyclone to make landfall near Brisbane, the capital of Queensland and Australia’s third-largest city, since 1974. However, on Saturday, it weakened into a tropical low—characterised by sustained winds of less than 63 kph (39 mph)—and stalled off the Brisbane coast for several hours. According to Matt Collopy, a Bureau of Meteorology manager, the cyclone's remnants are expected to move west across the Australian mainland over the coming days, bringing intense rainfall. “The primary concern now is the locally heavy-to-intense rainfall, which may result in flash and riverine flooding,” Collopy told reporters. Cyclones frequently occur in Queensland’s tropical north but are uncommon in the state’s more temperate and densely populated southeast, which borders New South Wales. 3 dead after light planes collided in Australia Police reported that a 61-year-old man, who went missing in a flooded river near Dorrigo in New South Wales, was confirmed as the first fatality when his body was recovered on Saturday. Additionally, several defence personnel sustained injuries when two military trucks involved in the emergency response collided in Tregeagle, New South Wales, on Saturday, according to police. Media outlets, including Nine Network television, reported that 36 people were injured in the accident, eight of them seriously, while two individuals remained trapped inside the trucks. A woman suffered minor injuries after the roof of an apartment building in the Queensland border city of Gold Coast was torn off on Friday, police said. She was among 21 residents evacuated from the building. Officials reported that a couple sustained minor injuries when a tree crashed through the ceiling of their Gold Coast bedroom during strong winds and rain on Thursday night. Queensland Premier David Crisafulli stated that 330,000 homes and businesses had lost power since Thursday due to the storm. No previous natural disaster had caused a larger blackout in the state’s history. In New South Wales, up to 45,000 properties were left without electricity on Saturday, although officials said tens of thousands had been reconnected by late afternoon. According to the Bureau of Meteorology, days of heavy rainfall have resulted in flooding across Queensland and New South Wales. The missing man was the only casualty among 36 flood rescues conducted by emergency teams in northern New South Wales in recent days, most of which involved vehicles attempting to drive through floodwaters, police said.

Dhaka, the capital of Bangladesh, is vulnerable to earthquake disasters due to spontaneous urbanization, high population density, haphazard growth of high-rise buildings, unplanned infrastructure, etc. Besides these, inadequate disaster management plans make Dhaka more vulnerable to disaster risk if a seismic tremor of magnitude 7 or over on the Richter scale occurs. An effective earthquake disaster prevention program is required at organizational levels to minimize the risk of disaster. Earthquake risk in Dhaka city  Dhaka is vulnerable to earthquake disasters for several reasons.  Located in risky seismic zone Bangladesh has been divided into three main earthquake zones. According to the seismic zoning of Bangladesh, Dhaka falls into Zone 2, that also includes Rajshahi, Natore, Magura, Meherpur, Cumilla, Brahmanbaria, and Feni. Here, the Chittagong-Comilla-Dhaka and Tangail areas have a possible earthquake risk of magnitude of 6 on the Richter scale. Unsafe structures The government of Bangladesh has developed national building codes, which include detailed guidelines for earthquake-resistant design of concrete and steel structures. However, these codes are not officially enforced. Due to the lack of effective enforcement mechanisms, it is feared that many new structures do not maintain the necessary requisites for earthquake-resistant construction. Therefore, the number of unsafe structures in Dhaka city is increasing.  Read more: 10 Most Earthquake-prone Countries around the World Furthermore, many high-rise buildings and garment factories are being constructed in Dhaka without following the rules. Furthermore, not leaving adequate open spaces while designing buildings also increases the risk of casualties if structures collapse due to earthquakes. Besides these, a significant portion of the structures of Dhaka city have encroached upon the streets and roadways, making those infrastructures more vulnerable for passersby and commuters during earthquakes.  As a result, after a major earthquake of magnitude 7 or over on the Richter scale, these structures can collapse, block streets, hinder rescue operations, and bring the greatest devastation to Dhaka city.  High population density The population density is very high in Dhaka city. With more than 23.9 million people, and an average of 38,000 people per square kilometer, Dhaka is one of the most crowded cities in the world. As the city is expanding quickly, many new buildings, bridges, roads, and other infrastructure are being constructed to fulfill the needs of this big population.  Millions of inhabitants of Dhaka city live in poorly made buildings.  Soil type Geographically, Dhaka city is made of soft, wet delta soil, which makes the structures more vulnerable to earthquakes.  Read more: Can Earthquakes Really be Predicted? Some effective organizational measures to mitigate earthquake disaster risk in Dhaka city As an earthquake is a natural disaster, it cannot be prevented. However, adequate measures at national, organizational, and individual levels can minimize the loss of lives and property. Here the organizational measures will be discussed. Decentralization  Dhaka is the center of the economy and administration of Bangladesh. Therefore, Dhaka’s risk in the context of the earthquake can make the economic stability, and public administration of Bangladesh vulnerable. Therefore, decentralization of key financial and administrative activities can minimize the damage if Dhaka faces any major earthquake.  Planning for water and airways  If a major earthquake occurs, the existing road communication system in and around Dhaka can be affected, but the effect will be less in waterways. So there should be a plan to restore the existing waterways (canals, rivers in and around Dhaka) for use during the earthquake emergency period.  Dhaka city is surrounded by three rivers, Buriganga, Sitalakhya, and Turag. These rivers can be again turned into the lifeblood of the city. These rivers need extensive dredging to ensure navigability around the year. The city's circular riverway can be a very useful communication route.  Furthermore, helicopters can also perform during emergency response. This will be an effective way in the field of rescue and emergency services distribution.  Read more: Earthquake Safety Tips for Parents to Keep Children Safe Build earthquake-resistant structures If the structures are not earthquake-resistant, severe damage to lives and properties can occur after an earthquake of 7 or more magnitude hits the city. To minimize the risk of earthquake destruction, earthquake-resistant buildings should be built.  The city authority can create strict regulations and make it obligatory for planners, engineers, and architects to consider earthquake-resistance capacity while making plans and designs. The common steps of building earthquake-resistant structures include creating flexible foundations; building shear walls, moment-resisting frames, and diaphragms; building Seismic Invisibility Cloak; using earthquake-resistant materials, etc. Seismic hazard mapping and database preparation It is essential to develop a comprehensive regional database of all recorded historical earthquakes in and around Dhaka city. A comprehensive regional seismic hazard map of Dhaka city should be prepared to incorporate appropriate building codes.  Read more: Turkey Earthquake: Why Did So Many Buildings Collapse? Resources such as scientists, seismologists, geologists, engineers, architects, planners, GIS experts, remote sensing experts, and other technicians should be prepared through higher education and relevant training programs to build leadership in earthquake hazard assessment research in Bangladesh. 

Flood control methods aim to minimise and prevent the detrimental effects of flood waters on road surfaces, human habitats and green spaces. Flooding can be caused by heavy rain or manmade changes to water bodies and water flows. To control the impact of flooding, countries around the world have taken diverse structural and non-structural types of initiatives. Reasons Behind Flooding: Why Water Overflows Flash floods can be triggered by natural phenomena, such as heavy rainfall, severe wind flows above water, tsunamis, cyclones, high tides, etc.   Now, what happens when huge amounts of water rush down? A portion of this water is retained in water bodies (rivers, lakes, canals, ponds, etc), vegetation, and soil surface while some water gets evaporated, and the rest of water passes through surface runoff. Floods occur when water bodies, soil, and vegetation cannot absorb the excess water. Human activities can influence the creation of excess water or prevent the natural ways of water absorption, retention or run-off. For example, deforestation, inadequate green spaces, failures/breakage/willful opening of dams or barrages, insufficient water reservoirs, impervious or paved surfaces, blocked drainage systems, clogged water bodies, etc can lead to inundation.  Read more: What Can Dhaka Learn from the Smart City Singapore Structural Methods to Control Inundation Structural flood control methods include man-made physical solutions, such as the construction of dams or barrages, water reservoirs, river dredging,  planting vegetation, etc. Besides, well-functioning drainage systems, channels to divert flood water, levees (dikes), etc are man-made structures to fight floods.  Barrages or Dams Dams or Barrages are designed to control the flow of water completely or partially. In the case of large barrages, associated reservoirs are built to create a space to hold the floodwater.  Dams are also used to generate hydroelectric power and water conservation. Construction and designs of barrages and the associated reservoirs depend upon standards set out by the respective governments. Usually, dams and reservoirs are built considering the watershed’s design flow rates, meteorological data, topographic features, streamflow, soil data, etc. However, dry dams serve for flood control only without any conservation storage. Diversion tunnels or canals Flood control tunnels or channels refer to empty large basins where the surface water can flow through. The water will be retained only during flooding periods.  These types of structures also include dry tunnels or channels that are built underground and run below the street levels of cities. When a flash flood occurs the excess surface water is drained out through these underground structures into a sea, river or other water bodies.  In many cases, underground flood tunnels or channels are built on the ancient natural waterways to reduce flooding. Read more: Green Roofs in Dhaka City: Pathway to Smart Urban Agriculture Floodplains and groundwater replenishment Groundwater replenishment is a great way to utilise the excess surface water. In this method, the flood is diverted onto land so that the soil can absorb excess water. The recharging of groundwater tables not only prevents flooding but also serves as a natural reservoir. People can extract the underground water through pumps during dry seasons or droughts.  River defences Rivers can cut down the risk of inundation by holding the water. Regular dredging is essential to preserve the navigability of the rivers during flooding. Structures such as reservoirs, levees, bunds, weirs, etc can be built to prevent rivers from overflowing their banks.  Flood barrier A flood barrier is also known as a surge barrier or storm surge barrier. This structure refers to a specific type of floodgate, designed to prevent inundation in the protected area behind the barrier. Flood barriers can also be built around individual buildings to prevent floodwaters from entering the buildings. Non-structural Ways to Prevent Flooding & Minimise Losses Non-structural flood control methods include flood risk management strategies, land-use planning, zoning, flood proofing, flood forecasting, advanced flood warning systems, flood insurance, evacuation of flood victims, rebuilding plans, etc.  Flood mapping Governments and policymakers utilise flood mapping as a tool to delineate the areas of potential flooding events, assisting planned decisions to prevent extreme flooding occurrences. Flood maps help create documentation for experts and policymakers to make informed decisions about flood hazards. It also generates conceptual models with information for public and private sectors about flooding hazards.  Flood modelling Flood modelling is another tool that is used to anticipate the severity of flood hazards and their effects on humans and structures. Flood modelling is conducted by combining diverse factors such as terrain, hydrology, urban topography, etc. This technology utilises geomorphic methods, remote sensing, hydraulic models, conceptual models, etc.  Stakeholder engagement Integrating stakeholder engagement into flood management provides a more complex analysis of the situation and allows enhanced public engagement in policy discussions. This creates paths for collective solutions through greater cohesion and consensus.  Flood risk assessment (FRM) Flood risk assessment can help to reduce the human casualties, and socio-economic losses caused by flooding. FRM is used to reduce flood risk and manage risks to lives and properties due to flooding.  Examples by country Canada To protect Manitoba from future floods, the authorities constructed a massive system of diversions, dikes, and floodways including the Red River Floodway and the Portage Diversion.  United States The USA took multiple flood barrier projects to protect the transit assets in Manhattan. In one case, they sealed subway entrances using a deployable fabric cover system called Flex-Gate that protects the subway entrances against 14 feet of water.  The USA revised their extreme storm flood protection based on new Federal Emergency Management Agency guidelines for 100y and 500y design flood elevations. After the 1993 flood across the Midwest, the federal government bought flood-prone lands as a part of their flood prevention plans. Several communities agreed and the government converted their lands into wetlands. These wetlands served as a sponge when storms and floods occurred.  Japan Tokyo built a 6.3 km long, 50-metre-deep concrete tunnel system called the Metropolitan Area Outer Underground Discharge Channel (MAOUDC). This tunnel diverts flood water from small to midsize rivers to the Edogawa River.

The ongoing flood is wreaking havoc on human lives, livestock, wildlife, and properties in affected areas of Bangladesh. Floodwater is washing away houses, trees, cattle, and people with the current. Apart from the rampage of floodwater, people also die from snake bites and other poisonous insects during the rainy season. To prevent such unwanted loss of lives, mass awareness is needed. Why Do Floods Increase Snake Movement? Floodwaters disrupt the natural environment, forcing snakes to leave their habitats in search of dry land. In a country like Bangladesh, where rivers crisscross the landscape, the risk of encountering snakes during and after a flood is particularly high. These reptiles may enter homes, fields, and even urban areas as they seek refuge from the rising waters. Types of Snakes Commonly Found in Flood-Affected Areas In Bangladesh, both venomous and non-venomous snakes prevail. A few of the common species are: Russell’s Viper: One of the most dangerous venomous snakes in Bangladesh.Common Krait: Known for its potent venom and nocturnal behavior.Spectacled Cobra: A venomous snake that is often found in residential areas.Rat Snake: Non-venomous but can be mistaken for a cobra due to its size. Knowing the types of snakes in your area can help you stay vigilant and take appropriate precautions. Read more: Russell's Viper: Myths, Facts, and Everything You Need to Know Cautions Before Inundation to Minimise the Risk of Snake Encounters  Preparation is key to reducing the risk of snake attacks during a flood. Here are some steps you can take before the floodwaters rise: Secure Your Home Ensure that your home is as snake-proof as possible. Check for gaps and holes in walls, doors, and windows where snakes could enter. Seal these openings with caulk or other suitable materials. Pay special attention to areas around pipes and drains, as snakes can use these as entry points. Clear Your Surroundings Keep your yard and surrounding areas clear of debris, tall grass, and piles of wood or trash. These can serve as hiding spots for snakes. Regularly trim bushes to reduce the likelihood of snakes taking up residence near your home. Read more: Essential Snake Safety Tips for Hiking, Trekking, Camping, and Traveling Double-check Household Items Store food, water, and other essential items on elevated platforms to avoid attracting snakes into your home during a flood. Snakes may enter buildings in search of food, and eliminating potential food sources can reduce this risk. Educate Your Family Teach your family members, especially children, about the dangers of snakes and how to identify common species in your area. Make sure everyone knows how to respond if they encounter a snake, including keeping a safe distance and notifying an adult immediately. Safety Measures During the Flood to Avoid Snake Attacks When floodwaters rise, snakes are more likely to be on the move. Here’s how to stay safe: Stay Indoor If possible, stay indoor during the height of the flood. Snakes may be swimming in the water or seeking shelter on dry ground. Avoid wading through floodwaters, especially in areas where visibility is low.

This can help you detect any hidden snakes before stepping on them. Wear boots and long pants to protect your legs from potential bites. Be Cautious Around Debris Floodwaters can carry debris like logs, branches, and trash, which may provide hiding spots for snakes. Be cautious when moving or working near debris, and avoid reaching into areas where you cannot see clearly. Keep Your Home Well-Lit Snakes tend to avoid well-lit areas. If you’re using a generator or battery-powered lights, keep your home well-lit at night to deter snakes from entering. Read more: Russell's Viper: Myths, Facts, and Everything You Need to Know

Continuous heavy rainfall over the past three days has worsened the flood situation in Sylhet for the second time in just 20 days. Nearly seven lakh people in the Sylhet metropolitan area and throughout the district are now stranded. In the metropolitan area alone, 50,000 people across 21 wards have been affected by flooding, according to Sylhet district administration sources. Sylhet experienced the first phase of flooding on May 27, affecting approximately seven lakh people across all upazilas. The water had not fully receded when heavy rainfall and hill torrents hit again on June 15, worsening the situation by Eid day (June 17). Heavy rainfall on Eid-ul-Azha morning was briefly followed by a recession, but rain resumed from Tuesday dawn, causing significant overflows in all rivers and streams in Sylhet. On Eid day, water levels were above danger points at two river locations. By Tuesday morning, water levels at four rivers were above danger points at six locations. Sylhet mayor holds emergency meeting to address severe flooding This morning, water was flowing above danger levels at six points of three rivers.   The Water Development Board in Sylhet reported that by 9 am today, the Surma River at Kanaighat point was 91 cm above danger levels. At another point in Sylhet, it was 31 cm above the danger level. The Kushiyara River was 46 cm above danger level at Amalshid, 92 cm above at Fenchuganj and 12 cm above at Sherpur point.  According to the district administration, 675,937 people in 13 upazilas, including Sylhet metropolitan area, have been stranded till midnight. Of them, 50,000 people of 21 wards out of 42 in Sylhet metropolitan area are stranded.  A total of 627 shelter centres have been opened in the district. Of these, 80 are in the metropolitan areas. A total of 17,285 people have taken shelter in these centres. However, most people are not willing to leave their homes and go to shelters.  A total of 1,323 villages in 13 upazilas of the district have been inundated.
