Typoons Impact Earthquake Patterns

"The Earth’s crust is under constant stress. Every now and then this stress is discharged in heavy earthquakes, mostly caused by the slow movement of Earth's crustal plates. There is, however, another influencing factor that has received little attention so far: intensive erosion can temporarily change the earthquake activity (seismicity) of a region significantly. ... They showed that there were significantly more small-magnitude and shallow earthquakes during the two and a half years after typhoon Morakot than before, and that this change occurred only in the area showing extensive erosion." - Excerpt from GFZ German Research Centre for Geosciences
