New Earthquake 'Swarm' Hits North of San Fransisco
Mitch Battros - Earth Changes Media
It is an area called The Geysers. This area is not unfamiliar to quake swarms. However, a recent escalation in magnitude has invited a heightened concern. A 4.2 magnitude quake occurred yesterday which is a triggering signal for seismologist to take note and monitor more closely. Hundreds of small quakes measuring between .05 to 3.0 mag. have been rumbling for many days, but it is yesterday's 4.2 that has brought some attention to this area north of San Francisco. The Geysers EQ List: http://quake.usgs.gov/recenteqs/Maps/San_Francisco_full.html The Geysers is a geothermal area in many ways like Yellowstone. As long as seismic and magma flow events remain nominal, it can be a great source of energy. However, if there is an escalation of earthquake activity, two possible hazards could occur. 1) Larger seismic events could 'trigger' surrounding tectonic fault lines creating the possibility of serious events. No place in the North American continent is more vulnerable to this scenario than California. 2) Magma reaches the surface destroying equipment and terrain, and no doubt other unexpected consequences. Geothermal power is energy derived from the heat of the Earth's core. "Geo" means "from the Earth" and "thermal" means "heat." Located at The Geysers, molten rock, or magma, exists very deep in the Earth where temperatures are extremely high. However, magma is relatively close to the surface in a few areas, particularly the volcanically active areas around the Pacific Rim. At The Geysers the magma is believed to exist at least four miles below the Earth's surface. The heat from the magma radiates to the layers of rock above heating water in the pores and fractures of the hot rock. A small portion of the heated water may rise to the surface causing hot springs, geysers, and fumaroles. At The Geysers, the reservoir water boils to steam and is trapped by an overlying layer of unfractured rock
