The earthquake swarms happened today in Brawley California will not trigger a big earthquake and it has nothing to do with San Andreas Fault.

This is due to water level at Salton Sea drastically dropping over the past few decades, has reach it critical point and makes the soil at south side of the lake where City of Brawley is located “Compacting”, because of the pressure from the lake dropped.

This is why all earthquake swarms are concentrated in one small area and all in Vertical motion- most of them are shallow quake within 10 to 12 Km in depth.

One measurable effect resulting from the swarms is: the Elevation of Brawley City will drop few inches. I believe USGS is conducting the survey at the moment.

This phenomenon is unique for Salton Sea in California only, it doesn’t happen anywhere in the world.
