Fortunately for us, the map the USGS runs, California-Nevada Fault Maps, is still functional. Not for long but maybe when the San Andreas blows, the government will reconsider the foolish plan to save money by terminating this very important feature. Look at that map today! California is a bowl of jello being shaken rather harshly! And the quiet middle section of the San Andreas has the least activity but warning quakes are appearing even right on the San Andreas especially where it is crossed by another major fault line in the Tejon Pass. This is where the previous major quake happened nearly 200 years ago and is the focal point of major, 7.5+ quakes.
I periodically warn about this major impending disaster. It can’t be pinned down to this day or that day but its approach is obvious, harshly outlined by minor quakes proliferating and the fact that at the top of the San Andreas and the bottom, there have been very major quakes recently and this means the middle must be readjusted quite soon, not 100 years from now. It is very soon. California has had drills and preparations for this inevitable event. Even so, due to lax building code restrictions, a huge number of dwellings are right on top of this shuddering, wakening dragon’s back and nearly all the main service lines connecting the coast to electricity and water as well as rail service and truck deliveries will all be cut instantly and disastrously the minute the San Andreas resets itself by moving the coast northwards 33 feet or so.
And the quakes continue in the Mississippi drain system, this time it is a Texas Earthquake which shook Today 2013 Erupts Near Shreveport, Louisiana
The Mississippi valley is a weak part of the continent. The North American continent is being shoved into the plates that run northwards along the Pacific coast and this caused the West to be a mass of heaving mountain ranges. But the middle of the continent is weak as it is in South America in the Amazon basin or Africa’s Congo basin as well as the Yellow River basin in China or the Volga basin in Russia. All continents tend towards weak centers with mountain building wherever they collide with other plates.
We may get another 7.5+ quake in the Mississippi region, too. Here is the data for today’s two 4.0 quakes south of Lake Tahoe:
As we look at the above maps, we see that these two moderate quakes were preceded by one quake the day before at Markleeville, CA, with the surrounding region having a number of small quakes. Then Markleeville had many, many aftershocks and an even bigger quake than the one at midnight. The San Andreas is the same, it will have a warning shake or two but the time differential between the first small 1.7 shake and the much bigger one was just 2 hours or so.
Unlike the Markleeville shakes, the San Andreas’s warning shot won’t be the entire length but rather, a key point such as the site where today’s quake happened. And this also is a cry for help from those of us who want a sane government that actually does things: we need the present USGS maps! Terminating them for a crummier, crappier system will cost lives. Not that our government is being run to function well.
