Do you know of any research on any linkage between the recent frequency of earthquakes and climate change?
No, I don’t. I’m also not sure if there is a recent uptick in earthquakes. They do seem to come in bunches but there are two reasons for that. First, random events form bunches all the time (as well as long gaps when nothing happens).Second, a large earthquake will often have precursors and aftershocks. Most news agencies etc. probably do what I do, which is to have an alert sent if an earthquake above a certain magnitude occurs. So, if an 8.0 or lager quake happens, like in Chile just now, we get an alert or two for the 6.0 quakes that happen first, then one for the 8.0, then one for the larger aftershocks for a few days, so there’s a clump of earthquakes happening all at once.
There are possible links between climate change and earthquakes but none of this has happened yet, it is of very low certainty, and probably would be minor. One is that if sea level goes up enough it may destabilize the edges of the continental shelves making it slightly more likely for bits to fall off. The other is as ice melts on Greenland and the Antarctic, there will be rebound of the currently depressed continental crust in those areas and that will likely be accompanied by some earthquakes.
