The history of earthquakes is nothing less than terrifying. Whether it’s the 1556 Shaanxi earthquake or something as recent as the 2023 Turkey–Syria earthquake, every major earthquake in the world involves destruction and death. For centuries, scientists, geologists, saints, and seers alike have searched for answers to one inevitable question: Can earthquakes be predicted? Let’s try to find out.

Myths about Earthquakes and Predicting Them

The phenomenon of earthquakes has long been attributed to mythical and otherworldly happenings. Thousands of years ago, the occurrence of an earthquake not only brought destruction but also paved the way for the fear of the unknown and faith in supernatural power. 

The concept of an earthquake is often attributed to Poseidon, the god of the sea in Greek mythology. It is said that Poseidon uses his trident to shake the earth which causes earthquakes. Similar stories are found in Japanese mythology where the giant catfish Namazu causes earthquakes. According to Mongolian mythology, the earth is placed on the back of a giant frog. When the frog stumbles, it causes earthquakes.

But beyond the myths, there are also some common misconceptions about earthquake predictions. Unlike the myths, these aren’t quite outlandish and are often passed on as hard facts. Some of the common misconceptions regarding earthquake prediction include: 

- Animals can predict earthquake 
- There are always advanced signs of earthquakes 
- Earthquake is preceded by sudden weather change 
- Planetary alignment influences earthquake 
- Increased seismic activity is a precursor for a large earthquake 
- A series of small earthquakes deters the chance of a large earthquake in a region.

Unfortunately, none of these concepts are true. There is no set pattern to earthquakes and neither does it have any identifiable precursors. And that brings us to the all-important question.

Can We Predict Earthquakes Now? 

The short answer is no, earthquakes cannot be predicted. Several methods are employed to make a gross estimation regarding earthquake probability in a certain region. However, it is currently not possible to predict earthquakes with precision. Some of the prediction methods include 

Long-term Seismic Hazard Assessment

Scientists and seismologists analyze historical earthquake data as well as geological studies, and information about fault lines to estimate the likelihood of earthquakes occurring in specific regions over long periods. The fault line estimation helps to understand which areas are highly prone to earthquakes.

Early Warning Systems

Some regions of the world like Japan and parts of the United States, have implemented early warning systems that use real-time data from seismometers. It provides a few seconds to a minute of advance notice before strong shaking from an earthquake reaches a location. These systems are connected to trigger alarms and automated responses to mitigate damage and protect lives.

Probabilistic Models

Many earthquake scientists use probabilistic models to estimate the probability of earthquakes in different regions of the world. These models consider factors like fault activity, historical seismicity, and strain accumulation to assess the likelihood of earthquakes of different magnitudes occurring within a given timeframe.

Precursor Research 

Precursor research is not exactly a very reliable prediction method. In this method, scientists study potential precursors like changes in groundwater levels, radon gas emissions, and electromagnetic signals to better understand earthquake processes. However, these precursors are not consistently reliable indicators for earthquakes. 

Measuring the Earthquake 

While it is not exactly possible to precisely predict the earthquake till date, scientists have come up with several measurement systems to correctly identify the intensity of the earthquake. The most common among these are magnitude measurement, seismometers, epicenter location, depth determination, and intensity scales. 

Each of these measurements is often crosslinked with each other to ensure measurement validity.

Final Words 

As of today, there is no reliable way to accurately predict an earthquake. There is also no way to predict the intensity as well as the havoc it may create. However, technological advancements have helped to understand the precautionary and safety measures needed in the wake of an earthquake. We hope that frontier technology will someday soon find a breakthrough in this mystery that has puzzled humans for thousands of years. Until then, we are at the mercy of nature.
