This is from the USGS/Cascades Volcano Observatory web page for current updates:

"Mount Hood earthquake swarm: The strongest earthquake in the Mount Hood area in decades occurred at 07:36 PDT today. The magnitude 4.5 event, which was located about 4.5 km south of the summit at a depth of 6 km, was widely felt. Hundreds of aftershocks followed, including two >M3. Typically, several earthquake swarms occur each year at Mount Hood."

It's getting close the the 4th. Must be the work of Al Qeada. Expecting another FBI terrorist alert anytime now to lookout for terrorist induced volcanic activity.

>At 7:36 a.m. an earthquake with a magnitude of 4.5 shook the Mount Hood area.

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 Eruption

[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

Here is the current earthquake map for Mt. Hood:   Recent Earthquakes for 122-45
