It happens all the time. This is just on too large a timescale to be of signifigance. Volcanism has been slowing down since the end of the late heavy bombardment I believe, but It may just be that the news fells the need to report it or you are experiencing the human condition of making patterns when there are none. But I will try to procure your dataI see a lot of earthquakes/volcanism in the news recently. Is there some analysis confirming global increase in seismic activity?
Would also like to see the statistics for the last couple of decades..
Maybe, I'll see if I can find that, but it could just be better monitoring and precision. There have been a few examples of human-caused fracking earthquakes, but those are rare and minor.Thanks for replies,
I understand that we cannot know for sure what was the frequency of earthquakes up to the time of modern seismology and, according to the link provided, there is no increase in frequency for earthquakes of magnitude 7 and up from 1980 to 2010, but what about those of smaller magnitude and data up to 2021?
