The other night, I watched Emmerich's epic world demise flick, 2012. When thinking on the geology of the movie, a bunch of head scratchings and question marks popped up. The movie was a bit obscure on the geology involved in a potential world end. But it did indeed address odd surface earthquakes, which is what is going on right now near Hawthorne, Nevada.


Ok, I must also admit, I did get a kick out of the conspiracy theory in the film, that of of saving the billionaire white trash. Now that was funny and also sad for me, for I am well aware of an existing system to save the worlds top heap, if and when the you-know-what-hits the fan.


2012 is a fun movie to watch when you are stone drunk with a hyperactive seismogram going bonkers next to you....


Ok, just a bit of fun there, now let's go back to geology.


Before I update you on the quake swarm near Hawthorne, Nevada, let me share with you a link on a volcanic eruption in Japan. Check this activity out:

Here's a great blog going on about it, with great and informative links! Plus more links.

Here is a list of earthquakes in the Hawthorne, Nevada area as of April 27. Now remember that these earthquakes are still going on as of this writing on May 19, 2011. And below that is a thread post from someone with a bit of knowledge, somebody named Tom in Hollister, Ca. The info below is in the links I provided.

From Adobe hills background information:


In many ways it is like the Adobe Hills swarm of 2004. The “Adobe Hills swarm” is named after a topographic feature in the vicinity of this sequence. Seismologists refer to this sequence as a swarm for several reasons. Unlike a typical mainshock-aftershock sequence, there is no obvious mainshock in this sequence. The “moment tensor solutions” show the quakes to be strike slip with normal fault component. This is the same kind of quake that is now occurring in the Hawthorn area.


Known quake activity in this area goes back as far as 1974. Since 1974, the CISN (California Integrated Seismic Network) has located more than 3,200 quakes within the box defined by latitude 37.85º – 38.15º, longitude -119.25º – -118.5º. During the past 20 years 170 quakes had magnitudes that exceeded 3.0. The largest quake in the area was a 6.3M that occurred in 1934 south of the Hawthorn swarm.


During the 2004 swarm I took a trip over there. The area is covered with cinder cones. The last eruptions were about 3 million years ago. Three surface cracks were found one of which showed a little offset. The cracks were about 800 meters long and 3 millimeters wide at the widest point. Faults in this area are not well known. The USGS Quaternary Faults and Fold Database of the United States shows few mapped faults in the epicentral region, but those to the vicinity are referred to as Huntoon Valley fault system. These faults are Late Quaternary in age and have a strike of N48°E with sinistral and normal sense of motion. This trend of the mapped faults is similar to the trend of seismicity and to the left-lateral planes in the moment tensor solutions of the larger events.


If this swarm is like the past swarms that have occurred in the area in will gradually end until the next time. Take Care...Don
