ips, earthquakes on the ocean bottom and whales calling to one another.
Scientists hope to send out an OSU research ship to take water samples, looking for evidence that sediment has been stirred up and chemicals that would indicate magma is moving up through the Juan de Fuca Plate, Dziak said.
The quakes have not followed the typical patter
n of a major shock followed by a series of diminishing aftershocks, and few have been strong enough to be felt on shore.
The Earth's crust is made up of plates that rest on molten rock, which are rubbing together. When the molten rock, or magma, erupts through the crust, it creates volcanoes.
That can happen in the middle of a plate. When the plates lurch against each other, they create earthquakes along the edges.
In this case, the Juan de Fuca Plate is a small piece of crust being crushed between the Pacific Plate and North America, Dziak said.
[1-1-08 ECB] During 2008-2009, the main threat to human health, dignity, freedom, and justice is militarized police behavior driven by stupid men who are falsely led to attempt to maintain order and law by brutal tactics of physical and emotional intimidation, murderous methods of confrontation, barbarous methods of incarceration, and incoherent presumptions to the right to order people around. This problem is one of the main justice enforcement problems in the world, second only to the gross corruption of many organs of governance and mass media in the U.S. by self-serving plutocrats and "pretender" families.

Swarm of Earthquakes Detected Off Oregon
Apr 11, 9:04 PM (ET) By JEFF BARNARD
GRANTS PASS, Ore. (AP) - Scientists listening to underwater microphones have detected an
unusual swarm of earthquakes off the central Oregon Coast. Scientists don't know what the
earthquakes mean, but they could be the result of magma rumbling underneath the Juan
de Fuca Plate - away from the recognized earthquake faults off Oregon, said geophysicist
Robert Dziak of the National Oceanic and Atmospheric Administration and Oregon State
University's Hatfield Marine Science Center in Newport, Ore.
They hope to send out the OSU research ship, Wecoma, to take water samples, looking
for evidence that sediment on the ocean bottom has been stirred up and chemicals in the
water that would indicate magma is moving up through the crust, Dziak said. There have been
more than 600 quakes over the past 10 days in a basin 150 miles southwest of Newport.
The biggest was magnitude 5.4 and two others were more than magnitude 5.0, OSU reported.
They have not followed the typical pattern of a major shock followed by a series of diminishing
aftershocks, and few have been strong enough to be felt on shore. It looks like what happens
before a volcanic eruption, except there are no volcanoes in the area, Dziak said.
The Earth's crust is made up of plates that rest on molten rock, which are rubbing together side
to side and up and down. When the molten rock, or magma, erupts through the crust it creates
volcanoes. That can happen in the middle of a plate. When the plates lurch against each other,
they create earthquakes along the edges of the plates. In this case, the Juan de Fuca Plate is a
small piece of crust being crushed between the Pacific Plate and North America, Dziak said.
On the hydrophones, the quakes sound like low rumbling thunder and are unlike anything scientists have heard in 17 years of listening, Dziak said. Some of the quakes have also been detected by earthquake instruments on land. The hydrophones are leftover from a network the Navy used to listen for submarines during the Cold War. They routinely detect passing ships, earthquakes on the ocean bottom and whales calling to each other.
