Palghar district has seen thousands of small earthquakes since November 2018, but Friday’s quake measuring 4.3 on the moment magnitude (Mw) scale was the first time the magnitude crossed 4 here.
Scientists, however, are divided on the primary cause of this phenomenon. Some believe it is related to groundwater levels, and others attribute it to tectonic activity. If high groundwater is the cause, the quakes may remain small. This phenomenon, called hydroseismicity.
can some one explain what is the concept of hydroseismicity?
