Earthquakes around the world

WORLDWIDE EARTHQUAKE REPORT OCTOBER 8_2024

Low levels of seismic activity occurred in the past 24 hours. Seismic silence of 24 hrs has been recorded so far for quakes of magnitude 5.0 or greater. The last M5+ earthquake occurred in the South Sandwich Islands.​

Category 5 hurricane Milton triggered an earthquake in Costa Rica?

Costa Rica is out of the path of Hurricane Milton but PhD Richard Cordaro thinks there was a relationship.

This is what the extremely powerful #Hurricane #Milton looks like from the International Space Station. It is strengthening and is once again Category 5!
Sustained winds 270 km/h!​

What ChatGPT says,​

Can hurricanes trigger earthquakes?
Hurricanes do not trigger earthquakes. While both phenomena involve significant geological forces, they are caused by different processes. Earthquakes result from the movement of tectonic plates, whereas hurricanes are atmospheric events driven by warm ocean waters and atmospheric conditions. However, the pressure changes from a hurricane can have minor effects on fault lines, but these effects are generally not strong enough to cause an earthquake.​

ChatGPT's answer is based on the old theory that earthquakes are only the result of the movement of tectonic faults ignoring that there is an electromagnetic component or gravitational forces that influence the occurrence of major earthquakes. Earthquakes of M5.6 or larger "tend to occur more often when planets and the moon reach specific positions in the solar system", according to SSGEOS studies.

The Google AI says:​

Yes, hurricanes can trigger small earthquakes in the ocean, called "stormquakes". These earthquakes are caused by the interaction of secondary waves from hurricanes with the seafloor. They can be as strong as a magnitude 3.5 earthquake and can last for days.​

Stormquakes are more likely to occur in places with:
●Large continental shelves
●Shallow, flat seafloors
●Ocean banks​

Some examples of stormquakes include:
●Hurricane Ike in 2008: Caused intense seismic activity in the Gulf of Mexico
●Hurricane Irene in 2011: Created stormquakes near Little Bahama Bank​

Can hurricanes trigger earthquakes?​

Can a hurricane lead to an earthquake? In most cases, the answer is no, but scientists haven’t ruled out the possibility in extreme circumstances.

According to several studies, including a group at Florida State University, there has been an uptick in quakes associated with some hurricanes, but these episodes have generally been weak in magnitude.

"This involves coupling of the atmosphere-ocean and solid earth. During a storm season, hurricanes or nor’easters transfer energy into the ocean as strong ocean waves, and the waves interact with the solid earth producing intense seismic source activity," Wenyuan Fan, an assistant professor of Earth, Ocean and Atmospheric Science at FSU, previously stated.

Can hurricanes trigger earthquakes?

According to researchers, hurricanes and other systems that create significant pressure gradients can cause seismic events. Some have even labeled these events’ stormquakes,’ though they are not believed to be particularly strong. Examples of hurricanes that have been linked to increased seismic...

I think that we cannot exclude the possibility that a powerful hurricane could provoke a moderate earthquake.​

In the past 24 hours, there were 876 quakes of magnitudes up to 5.7:

●1 quakes above magnitude 5
●39 quakes between magnitude 4 and 5
●88 quakes between magnitude 3 and 4
●212 quakes between magnitude 2 and 3
●536 quakes below magnitude 2 that people normally don't feel.
