Description
English: On May 18, 1980, at 8:32 a.m. Pacific Daylight Time, a magnitude 5.1 earthquake shook Mount St. Helens. The bulge and surrounding area slid away in a gigantic rockslide and debris avalanche, releasing pressure, and triggering a major pumice and ash eruption of the volcano. Thirteen-hundred feet (400 meters) of the peak collapsed or blew outwards. As a result, 24 square miles (62 square kilometers) of valley was filled by a debris avalanche, 250 square miles (650 square kilometers) of recreation, timber, and private lands were damaged by a lateral blast, and an estimated 200 million cubic yards (150 million cubic meters) of material was deposited directly by lahars (volcanic mudflows) into the river channels. Sixty-one people were killed or are still missing. USGS Photograph taken on May 18, 1980, by Austin Post.
Català: El 18 de maig, a les 8:32 a. m. Temps del Pacífic, un terratrèmol de una magnitud de 5,1 va fer trontollar la muntanya St. Helens. La protuberància l'àrea circumdant relliscà en una gegantina esllavissada de roques i un allau de rocam, alliberant la pressió, desencadenà una erupció de pedra tosca i cendra del volcà. 400 metres del puig van col·lapsar o van sortir volant. Com a resultat 62 quilometres quadrats de la vall van ser emplenats per la runa, 650 quilometres quadrats de llocs d'esbarjo, bosc, i finques privades van ser damnificades per una ràfega lateral, i una quantitat estimada en 150 milions de metres cúbics de material van ser dipositats per corrents de fang volcànic en els canals del riu. Cinquanta set persones van morir o han desaparegut (18 de Maig de 1980, Austin Post, USGS)
