Loading ...Thanks for the site. Earthquakes or bigger ones seem to be more numerous buy haven’t looked into it. This one around the world not related to each other seemed different.
Have to be in geology or focused on one area. The reason is in some places there’s a balance between thinning and thickening via volcanoes, especially underwater and subduction zones. Other areas might be different. The earth core cooling over time might have something to do with it too but don’t quote me on that.
