Subject: RE: BS: Volcano activ , slept for ten th,years From: Q (Frank Staplin) Date: 04 May 08 - 03:47 PM According to an Iceland tour site, Hekla has had four eruptions that caused "much" damage, 1104, 1300, 1341, 1693. Many smaller. Vacation properties nearby should sell at bargain prices. |
Subject: RE: BS: Volcano activ , slept for ten th,years From: Don Firth Date: 04 May 08 - 03:17 PM That should be "Juan de Fuca." Juan de Fuca was a Greek navigator (real name, Ioannis Phokas—John Focas) employed by Spain in the sixteenth century to sail northward from Mexico and look for the "Strait of Amian," an imagined northern passage from the Pacific Ocean to the Atlantic Ocean.

Subject: RE: BS: Volcano activ , slept for ten th,years From: Don Firth Date: 04 May 08 - 03:04 PM Back in 1980 (about this time of year, Sunday, May 18th, 8:32 a.m.), Mount St. Helens, 96 miles south of Seattle, erupted. It killed 57 people and destroyed 250 homes, 47 bridges, 15 miles (24 km) of railways, and 185 miles (300 km) of highway. The eruption caused a massive debris avalanche, reducing the elevation of the mountain's summit from 9,677 feet (2,950 m) to 8,365 feet (2,550 m) and replacing it with a mile-wide (1.5 km-wide) horseshoe-shaped crater. The debris avalanche was up to 0.7 cubic miles (2.9 km³) in volume. The eruption was triggered by a 5.1 earthquake, caused by slippage of the Jaan de Fuca tectonic plate sliding under the North American plate—the same geological phenomenon that spawned all the volcanoes in the Cascade mountain range on the west coast of the United States and Canada. Geologists, I am told, are concerned about the greater danger of a possible eruption of Mount Rainier, a 14,411 foot peak 54 miles south of Seattle and looming over the cities of Tacoma and Olympia (the state capital). There are several small municipalities much closer to the mountain, and on the mountain itself, there are lodges, resorts, ski areas. . . . This is a geologically active area, due to the collision of the tectonic plates beneath our feet (subduction zone), and although it is sufficiently peaceful for most people to be unconcerned, there are small tremors in the area almost every few days. Most people don't even notice them. But the Nisqually quake, occurring at 10:54 a.m. on Wednesday, February 28, 2001, was one of the largest recorded earthquakes in Washington state history. The quake measured 6.8 on the MMS and lasted approximately 45 seconds. It got everybody's attention!! And geologists keep warning lugubriously that "The Big One"—a 9+ quake, triggering tsunamis off the west coast—could come at any time. I wonder what effect that might have on the Cascade Range volcanoes. . . . It appears that terra firma is not so firma after all. Don Firth P. S. Hang on, Skarpi! (I never really did like "rock 'n' roll" much, especially that kind!) |

Subject: BS: Volcano activ , slept for ten th,years From: skarpi Date: 04 May 08 - 01:58 PM Hallo all , I saw the news yesterday about the volcano in Chile , it has been a sleep for ten thousand years ? and started a eruption . uhh I wander I live only 2 to 5 km away from several volcanos and I am told that they wont erupt? hmmm I must find me away to run then , this proof that a volcano can never cool down for sure . so people watch out earth is changin , the Atlantic ridge goes through Iceland and I think its only 10 to 15 km from my home to the crack . just a thought , ATB Skarpi Iceland |
