3.2-magnitude earthquake strikes near San Francisco

[Brother Buzz]

This earthquake didn't amount to much as there was zero damage, no ground rupture, and almost nobody felt it, but I found it interesting that the epicenter is the same as San Francisco's 1906 earthquake (like, within a whole whopping mile).

The earthquake, reported at 5:36 a.m., was recorded at a 4.9-kilometer depth, according to United States Geological Survey. The quake occurred right along the San Andreas Fault Line.

The epicenter of the tremor was in the Pacific, about 6.8 miles from the Golden Gate Bridge, 9.9 miles from San Francisco and 6.8 miles from Tamalpais-Homestead Valley in Marin County.

The USGS is calling Tamalpais-Homestead Valley the location of the earthquake.

1. all of northern california needs dozens of 3.2M quakes

maybe hundreds.

to relieve the pressure of the faults slipping past each other.

2. That's the theory, BUT....

if you relieve pressure at one spot, it just loads another, and it could load an area already wanting to unload its own 3.2, but could explode with something much larger And with the intricate fault systems in the Bay Area, we are discovering the pressures can actually be transferred from one fault to another. It's complicated.
