An acquaintance in Facebook recently posed the question:
Does global warming cause earthquakes?
Earthquakes are rare in the eastern U.S. because the region is farther from a fault line.
Andrew Hynes, a tectonics expert at McGill University, said the issue is not so much the load shift on the earth’s crust, but rather the increased fluid pressure in the fault that lubricates the rock, allowing the plate to slide 웨스트월드 1화 다운로드.
“All earthquakes except those produced by volcanic activity are essentially the unsticking of faults,” he said 다운로드. In other words, if you pump fluid into a fault, it will reduce the friction and the rock can slide. (from AccuWeather)
Can the added melt from glaciers create stress on the earth’s upper crust, injecting more fluid into the rocks, thus creating earthquakes 네이버 북스? The answer is yes, earthquakes at shalllow depths. Which is exactly what states like VA, MD, NY, and NC experienced.
This increase in sea level means more pressure on the sea floor, which can effect everything from gravity fields to horizontal crustal motion. Of course, the recent earthquake on the East coast brings to mind the threat of shifting tectonic plates 다운로드.
