A strong undersea earthquake has hit parts of western Indonesia, but no tsunami warning was issued and there have been no immediate reports of damage or casualties. The U.S. Geological Survey says Friday’s 6.2-magnitude quake struck at a depth of 20 kilometers (12 miles). Indonesia’s Meteorology and Geophysics Agency says it was centered about 160 kilometers (100 miles) southeast of Mentawai island, off western Sumatra.
This event has been reviewed by a seismologist.

Last night I was looking at the Ca/Nv earthquake map that covers the last 7 days. I noticed a few things. First Monday, September 10, 2012 at 08:44:42 AM there was a 3.3 at a depth of 2.1 miles. Could this quake along with low water levels and the strong storm that hit this area be why the smell was so much worse than in the past? There were a series of smaller quakes in the same area of the Salton Sea that followed the quake on Monday.
I then began going down the list at this site. I noticed a pattern where one quake or two would be down south then one or two upnorth of San Francisco. Occasionally one would be in the Yosemite area or up near Eureka. I checked the site again this morning and noticed several 3+ quakes near Eureka.
It seems to me that the plates along the west coast are getting more active. I know they are always having small quakes. I feel as though the volcanos in Central America are connected to the volcanic sulfer smell continuing to come from the Salton area. I would not be suprised if there becomes more volcanic activity from the volcanos up through California.

Dear SpaceJockey, why do you consider it was due?

I think Indonesia gets more than it's fair share of the pie, in fact recently it seems a bit busier, but I am curious as to your reasoning.

According to my Earthquake App on my iPad it was on the island of I think it's called Valverde, or maybe it is Ferro/Hierro
