Pompeii Scenario

The eruption at Chaitén volcano is causing authorities to worry that a collapse could trigger ash depths similar to Pompeii.

There is precedent for such concern, according to SERNAGEOMIN (Chile’s National Geologic and Mining Service) official who pointed out that similar volcanoes (in Mexico and the Philippines, for example) have collapsed on the seventh or eight day of continuous eruption.

“Pompeii is in some ways similar,” added Lara, referring to the Roman city famously destroyed in AD 79 by Mount Vesuvius. “There was a pyroclastic flow that resulted in the consequences we all know. That’s exactly the worst case scenario that we’ve defined here”.

Another worry: the amount of animals that have been abandoned near the volcano;
About 600 animals, mostly horses, dogs and cats, are thought to be in Chaiten, with another 600 in Futaleufu, 45 miles south of the volcano.

The agriculture ministry has been moving animals from Futaleufu. There are 7,000 head of cattle there, 6,000 in Chaiten and 10,000 in Palena, the ministry said. There also are 28,000 sheep in the region.

Cascadia Subduction Zone Is The Cause!
My friend Robert Somerville calls my attention to an article in the NewScientistEnvironment that says the San Andreas fault is a victim. It's the Cascadia Subduction Zone's fault.
Chris Goldfinger and colleagues at Oregon State University, Corvallis, analysed sediment records from deep sea canyons that stretched back over the last three thousand years, looking for the disturbed strata that are the hallmarks of big earthquakes.
They found evidence that "...the massive Cascadia quakes – eight of which Goldfinger estimates exceeded magnitude 9.0 on the Richter scale – trigger events that top out around magnitude 7.9 along the San Andreas by stress transfer."

Their evidence also suggests that the Cascadia is 90 years overdue for a "big one".

Oregon Earthquake???

Connection, Reno and Long Valley???
So far, I've read no theories for the swarm taking place in and around Reno, NV. Some scientists are warning of something much bigger coming, because these don't appear to be earthquake and aftershocks. I note with these maps that the Reno swarm is not that far from the Mammoth Mountain quakes (or Long alley Caldera). Maybe 125 to 150 miles! Is there a connection? Long Valley appears to be relatively quiet for the moment.


Update:

I asked if there was a connection between Reno and Long Valley. Michael Hall brought this chart to my attention

Wikipedia defines Peak acceleration (%g) as

Peak ground acceleration (PGA) is a measure of earthquake acceleration. Unlike the Richter magnitude scale, it is not a measure of the total size of the earthquake, but rather how hard the earth shakes in a given geographic area.
It appears there is that connection!

Ocean Off Oregon is "Poorly Mapped"
Scientists have discovered a volcano on the floor of the North Atlantic about 90 miles south of Iceland.
The structure...rises about 3,300 feet (1,000 meters) above the surrounding sections of the (Mid-Atlantic) ridge, coming within 1,300 feet (400 meters) of the surface.

At its base the volcano is approximately 30 miles (50 kilometers) across. The peak contains a depression known as a caldera that is 6 miles (10 kilometers) wide.

That so large a structure could go undetected for so long "indicates how little is known about the seafloor," said (Ármann) Höskuldsson, (a University of Iceland volcanologist who was part of the international team that discovered the volcano last summer.)

Here's the tie to Oregon. So much of the earth is covered by water that "...ocean scientists studying a swarm of earthquakes off the Oregon coast are having a hard time pinning down the temblors' source, because much of the seabed is poorly mapped.

BTW, the fifth earthquake in one day was a 3.8!

Akron Magnetic Boundary In Illinois Earthquake
On June 21, 2006, I posted about Ohio and the tenth earthquake there in the year. I wrote
Scientists say Ohio's earthquakes are linked to an ancient scar six-thousand feet deep that is known as the Akron Magnetic Boundary. The fault runs diagonally through Summit County and into Geauga, Lake and Ashtabula counties and was formed when North America tried unsuccessfully to split a billion years ago.
That same fault appears to be associated with todays 5.4M in Illinois.
5.4 Earthquake Near New Madrid Seismic Zone!

On the government’s map of relative risk of damaging earthquakes, a Midwest hot spot stands out. (Excerpted from U.S.G.S. image.)

The (5.4M) earthquake occurred in the Wabash Valley fault system, adjacent to the New Madrid Seismic Zone, (Dave) Applegate, (USGS senior science adviser), said.

That zone, named for the town of New Madrid, Missouri, was the site of a series of huge tremors in 1811 and 1812.
