Earthquakes: Can Malta Expect A Big One After The Most Recent Foreshocks?

Article Featured Image

While the recent series of small earthquakes may have caused concern among residents, it’s crucial to understand that not all earthquakes are linked and not all series of small earthquakes lead to a larger one.

However, researchers have found that areas with increased seismic activity are more likely to experience a larger earthquake in the future.

This phenomenon, called “foreshock activity”, can provide valuable information for predicting when and where a larger earthquake might occur.

For instance, the 7.1 magnitude earthquake that struck Mexico City in September 2017 was preceded by a series of small earthquakes, which scientists had warned could signal a larger event.

Similarly, the 8.8 magnitude earthquake that hit Chile in 2010 was preceded by a series of foreshocks, the largest being a 6.2 magnitude quake just a few hours before the main shock.

On the other hand, there have been instances where small earthquakes have not led to a larger one.

For example, the earthquakes that struck Southern California in the summer of 2019 were not followed by a larger event, despite a swarm of small earthquakes in the area.

It’s important for residents of Malta to stay informed and prepared for a possible earthquake. The first step is to be aware of the risks, which means staying up to date on earthquake information and monitoring the frequency and magnitude of earthquakes in the area.

Residents should take steps to prepare their homes and families for a possible earthquake. This includes securing heavy furniture and appliances, creating an emergency plan, and having an earthquake kit on hand.

So, can Malta expect a big one after the recent foreshocks? The answer is uncertain. While the series of small earthquakes could be a warning sign of an impending larger event, it’s too soon to say for sure. However, by being prepared, Malta can be better equipped to weather any seismic events that may occur in the future.

Lovin Malta spoke to Professor Sebastiano D’Amico, Head of the Department of Geosciences at the University of Malta, to find out more.
