this is how it's stated in the article: "Below the summit, however, Waythomas and others discovered that heat from the volcano has already melted or evaporated away about one-fifth of the Drift Glacier. That's nearly commensurate with the "cubic kilometer ... about one-fourth of the glacier" that was lost to melting 20 years ago, Waythomas said." So it sounds to me that they are saying the 1/5 of the glacier that they estimate to be melted this go-round is similar to what was melted during the last eruptin (lasting 4 months) Keep in mind that this was their assessment from only a flyover - I don't think they've had a chance to really inspect anything since last night's & today's eruptions. That might not take into account the thickness of the glacier each time, etc... "quick science" Here's the latest report: 2009-03-28 15:25:57 Seismicity over the last 30 minutes has gradually increasing on several stations. Snow and ash are currently obscuring web camera views of the volcano from AVO's hut camera. --Previous Message-- : How much of the glacier melted during the 89 : eruption? : : --Previous Message-- : : there's more night photos at AVO, awesome : photography... : : it's already melted quite about 1/5th of the : glacier, per the ADN story & less than 1 : wk into the eruptions - this one's going to : be one for the record books I think - hope : the dikes at the drift river terminal hold : : --Previous Message-- : Very cool!! : : I was reading the ash samples showed a : pumice structure which indicate that it was : generated by fresh lava at the surface. : : That indicates a dome building and : collapsing process will most likely happen : for a while; hence, the eruptions will occur : for some time. : : : : : : :
