Recent Earthquake Statistics.
In fact, a quick look at earthquake statistics over the last twenty years shows that this is not the case.
The ComCat earthquake catalog contains an increasing number of earthquakes in recent years not because there are more earthquakes, but because there are more seismic instruments and they are able to record more earthquakes. The Costa Rica News (TCRN) – If it seems like earthquakes and erupting volcanoes are happening more frequently, that’s because they are.
