On Friday we drove 108 miles from Poulsbo to our next stop in Kelso, the launching point for touring Mt. St. Helens National Volcanic Monument .
Interesting Facts about Mt. St. Helens from the U.S. Geological Survey:
- March 20, 1980—A magnitude 4.2 earthquake signaled the reawakening of the volcano after 123 years.
- Spring 1980—Rising magma pushed the volcano’s north flank outward 5 feet per day.
- Morning of May 18, 1980— The largest terrestrial landslide in recorded history reduced the summit by 1,300 feet and triggered a lateral blast.
- Within 3 minutes, the lateral blast, traveling at more than 300 miles per hour, blew down and scorched 230 square miles of forest.
- Within 15 minutes, a vertical plume of volcanic ash rose over 80,000 feet.
- Afternoon of May 18, 1980—The dense ash cloud turned daylight into darkness in eastern Washington, causing streetlights to turn on in Yakima and Ritzville.
- The volcanic ash cloud drifted east across the United States in 3 days and encircled Earth in 15 days.
- 14—Lahars (volcanic mudflows) filled rivers with rocks, sand, and mud, damaging 27 bridges and 200 homes and forcing 31 ships to remain in ports upstream.
- 15—The May 18, 1980 eruption was the most economically destructive volcanic event in U.S. history.
- 16—Small plants and trees beneath winter snow, and roots protected by soil, survived the May 18, 1980 eruption and now thrive.
