[CitizensTruth] Earthquake watch

[Hal Snyder]

1. Several persons have emailed off-list about this morning's  
earthquake in Illinois.

5.2 [Richter magnitude] earthquake rocks large region of Midwest
Residents across the Midwest were awakened Friday by a 5.2 magnitude  
earthquake that rattled skyscrapers in Chicago's Loop and homes in  
Cincinnati but appeared to cause no major injuries or damage.
The quake just before 4:37 a.m. was centered six miles from West  
Salem, Ill., and 45 miles from Evansville, Ind. It was felt in such  
distant cities as Milwaukee, Des Moines, Iowa, and Atlanta, nearly  
400 miles to the southeast.

I was working on a web site. The old cat who keeps me company was the  
first to notice something. He started fussing maybe 10-20 seconds  
before I felt something. There's nothing else that feels quite like  
this (second quake since moving into this house) - a slow lateral  
back-and-forth shift. This morning it was clearly a north-south  
movement.

2. Subsidence?

About the previous posting, relating aquifer depletion and subsidence  
to the Oregon earthquake swarm - that's probably too much of a reach.  
The latest Oregon quake swarm seems to originate offshore from the  
middle of a tectonic plate.

This isn’t the first time the researchers have recorded earthquake  
swarms off the Oregon coast, Dziak said. In 2005, they recorded  
thousands of small quakes within a couple of weeks along the Juan de  
Fuca Ridge northwest of Astoria. Those earthquakes were smaller, he  
pointed out, and located along the tectonic plate boundary.

This is the eighth such swarm over the past dozen years, Dziak said,  
and the first seven were likely because of volcanic activity on the  
Juan de Fuca ridge. The plate doesn't move in a continuous manner and  
some parts move faster than others. Movement generally occurs when  
magma is injected into the ocean crust and pushes the plates apart. -
