MOUNT HOOD - Seismologists are keeping a very close watch on Mount Hood today after at least two moderate earthquakes rattled the area.
At 7:36 a.m. an earthquake with a magnitude of 4.5 shook the Mount Hood area. So far there are no reports of damage or injuries.
Bill Steele of the University of Washington's Pacific Northwest Seismographic Network said the quake was centered about three miles south of the summit of Mount Hood and was about four miles deep.
It was the strongest quake in the area in recent decades, he said, and had been followed by hundreds of small aftershocks.
One of the more significant aftershocks registered 3.8 at 11:49 a.m.
Steele said it was related to the volcanic activity of the mountain but that it did not signal any eruption.
"It is reasonable to expect aftershocks of a magnitude of three or greater" within the next few weeks, he said.
Steele said there have been several groups of quakes around the mountain since the 1970s. "This was stronger than any of those," he said.
"It shook the mobile home, the beds, the floors, but obviously there was no damage," Dale Roberts of Maupin said.
Mark Vincent, general manager at Timberline Lodge ski area on the mountain said the quake registered "a sharp jolt" and a couple of lesser aftershocks.
"If you were sitting you might have felt (the aftershocks) but if you were walking you might not have felt them," he said.
"We checked out the facilities and everything is fine."
A quake of a magnitude of 4 can cause moderate damage in built-up areas. A magnitude of 5 can cause considerable damage.
On May 15 Oregon felt two earthquakes, one measuring 4.3 in the Klamath Falls area and another of a 5.4 magnitude off the coast of Coos Bay.
There were no damage or injury reports from either quake.
Steve Malone of the seismographic network said they were still not sure Saturday whether the Mount Hood earthquake was directly related to volcanic activity or related to the movement of the earth's plates and stresses and strains that caused the May earthquakes and the larger Scotts Mills quake in Oregon's Willamette Valley in 1993.
Those quakes, he said "are run of the mill quakes that occur throughout the Pacific Northwest."
"The Mount Hood quake had some characteristics that make it somewhat different from those but not clearly volcano-related," he said.
"It had some characteristics of both types of events."
Buffalo News - Lake Placid feels temblor, aftershock of April quake - 26 Jun 02
LAKE PLACID - Residents of the Adirondacks felt a small temblor Tuesday morning. The earthquake, which occurred at 9:40 a.m. and had a magnitude of 3, was centered about 15 miles southwest of Plattsburgh, near the epicenter of an earthquake in April, according to seismologist William Ott of the Weston Observatory at Boston College.Ott said Tuesday's shake probably was an aftershock of the April earthquake. There were no immediate reports of damage or injuries. Sandy Caligiore, spokesman for the state Olympic Regional Development Authority, based in Lake Placid, said he felt shaking for about five to 10 seconds.
April 20, an earthquake with a 5.1 magnitude shook Au Sable Forks about 5 a.m., collapsing roads and rattling homes from Maine to Maryland. There were no injuries. Damage was estimated at $14 million. An aftershock May 24 had a magnitude of 3.3 and was centered about 20 miles southwest of Plattsburgh.
Mt. St. Helens started with a 5+ earthquake as follows (source: 15 ):
"...The first hint of trouble came on March 20th, 1980, when the mountain gave a violent shudder, bouncing the Richter needle to 4.1. On March 27, the first eruption opened a crater and sent a plume of ash and steam 7,000 feet into the air. Quake followed quake in the next few weeks. Scientists had long expected this. Now they predicted a major eruption." Corps: Before the EruptionHere is the current earthquake map for Mt. Hood: Recent Earthquakes for 122-45[On May 18, 1980] "A magnitude 5+ earthquake at 8:32 a.m. set the blast in motion. Huge masses of rock began sliding down the mount's north flank, releasing gas pressure inside. Within seconds the whole north face exploded in a cloud of ash, rock fragments, and hot gases rushing northward at speeds up to 120 miles per hour. Once uncapped, the eruption continued vigorously until late afternoon. The top 1200 feet of the mountain rose in a billowing dark-gray plume of pulverized rock 11 miles high, and began drifting east. ..." Corps: The Crises and Response
Oregonian: The Collapse of Enron
Cooper [PGE's new CEO] downplayed the furor that has arisen over Enron's past trading strategies, which critics have blasted as manipulative, greedy and base. He said PGE, under pressure from the Federal Energy Regulatory Commission to explain any ways it may have aided Enron in carrying out these strategies, has been unfairly drawn into the investigation. "I don't believe at the end of the day FERC will find any problems here at PGE," he said. His greatest sympathies, he said, were toward Enron and PGE employees, *who lost millions in retirement savings when Enron collapsed. "It's an unbelievable shame, and a terrible outcome," he said.

A woman in the Seattle area is also an "earthquake sensitive" and just knows by the changes in her body a quake is coming. She can tell the general intensity, how soon and pretty closely the area of the epicenter. Her kids hate it because Mom is always right. As best I can remember, she has been accurate on all quakes since long before Mt. St. Helens. She is a Christian and doesn't try to get info, she just feels ill and knows, like one would hear a sound.
Another woman, Charlotte King, of Salem, Oregon, is an earthquake sensitive (click here for Stateman Journal article). She is so accurate that some city and county planners take notice and consider her predictions along with scientific ones.
That gift may indeed be from the Lord and with all gifts He should get the credit or the glory. Some have gifts and think they are personally great, but that is error and an incorrect response to blessings. Birds and animals can often tell in advance, particularly deaf ones who rely on senses other than hearing, so we shouldn't be surprised when some people can also tell in advance. Rather than quickly discard warnings, it is wise to hold them, consider them and pray about them. Faith is an action word and without action isn't faith.
