Is Earthquake Activity Unusual? The Past Decade Has Had Many More Major Quakes

Here is today’s earthquake map.  Ever since the 2004 Indian Ocean earthquake and tsunami we have seen many other major quakes equal in strength.  The Indonesian one was a 9.1 or greater and the 2011 Tōhoku earthquake was at least a 9.0.  A quick look at the below graph shows very clearly that great or small, quakes are more frequent and more violent this last decade:

The charts above do not have the last four years nor the tens of thousands of more deaths.  Chile had two quakes, one in 2010 at 8.8 on the Richter scale and another one April, 2014, of similar size 8.2. In 2012, Sumatra had an 8.6 and a 8.2 quake the same day.  All of this is most interesting since we expect daily for a 8.0+ major quake along the San Andreas fault in California.

 

Nervousness about a major, overdue quake in California is also causing fears about the New Madrid fault region, too.  I Googled ‘unusual earthquake activity’ and got these stories:  April 14, 2010: USGS Release: Is Recent Earthquake Activity Unusual …

I have observed the quakes in California for a number of years.  This is a VERY active map indeed.  Far, far, far more active than say, in 2002.  A million times more active.  Activity along the entire outline of the Central Valley and into Nevada is VERY unusual.  Mostly, it is an occasional quake, not a complex number of them along multiple fault lines.

 

Ever since the 10/14/2013 — Salton Sea Volcanic Earthquake Swarm (this happens to be my birthday, too! ) this has continued nearly nonstop which means something nasty is lurking nearby.  Now, we have fairly big quakes on all the associated faults in LA on a weekly and even daily basis.  How many red flags does it take to warn people of the inevitable?

 

Along the rim of fire, we have more volcanic action:  Alaska Volcano Observatory:  Pavlof Volcano Eruption ‘Escalates,’ Alaska Officials Raise Alert Level

Bit by bit, volcanoes are hiccuping into the stratosphere and this, in turn, encourages weather events due to the fine dust.  More about that later. What is typical and very pathetic is this news:  California’s Early Warning Quake Plan Lacks Funds.  We need billions for ‘global warming’ not preparing for one of the biggest quakes in California in the last 100 years.

OES director Mark Ghilarducci said Gov. Jerry Brown, who signed SB135 last year authorizing construction of an early warning system, wants to see the system “up and running in two years.” But, the bill doesn’t provide for its funding.

 

The estimated price tag of a system in California, which would also cover Oregon and Washington, is $23.1 million, with an annual operating budget of $11.4 million.

 

Officials are looking for private sector help in planning and funding the delivery of warning information to the public and also in taking actions prior to and following a major quake.

 

Ideas discussed at the meeting included collaborating with large retailers and hospital associations; implementing a crowdfunding project; tapping public funds through such things as voluntary donations on tax filings or an earthquake license plate; or using excess funds from the California Earthquake Authority, the state-run insurance program.

    More likely it is plate tectonics at work: major 9 mag quakes trigger many others over several years.

    They expect a biggy off washington state, overdue, here on VI we will be hit by it too. My fingers have been crossed so long, they have fused together
