Masih dari website yang sama ... Dugaan Mas Habash ternyaat valid ... ada vent lewat samping disini, gambarnya cukup meyakinkan. Yang terlihat bukan tempat masuknya air tapi tempat keluarnya letusan : http://scienceblogs.com/eruptions/2010/08/sinabung_and_etna_updates_for.php Sinabung and Etna updates for 8/30/2010<http://scienceblogs.com/eruptions/2010/08/sinabung_and_etna_updates_for.php> Category: Ash fall <http://scienceblogs.com/eruptions/ash-fall/> • Aviation<http://scienceblogs.com/eruptions/aviation/>• Etna <http://scienceblogs.com/eruptions/etna/> • Explosive eruption<http://scienceblogs.com/eruptions/explosive-eruption/>• Indonesia <http://scienceblogs.com/eruptions/indonesia/> • Italy<http://scienceblogs.com/eruptions/italy/>• Sinabung <http://scienceblogs.com/eruptions/sinabung/> • Volcanic hazards<http://scienceblogs.com/eruptions/volcanic_hazards/>• Volcano monitoring <http://scienceblogs.com/eruptions/volcano_monitoring/> • ash plumes <http://scienceblogs.com/eruptions/ash_plumes/> • evacuations<http://scienceblogs.com/eruptions/evacuations/>• webcam <http://scienceblogs.com/eruptions/webcam/> Posted on: August 30, 2010 8:20 AM, by Erik Klemetti<http://scienceblogs.com/eruptions/> Classes starting today, so I have to be brief: [image: Sinabung2.jpg] <http://scienceblogs.com/eruptions/Sinabung2.jpg> *Unique twin ash plumes from Sinabung in Indonesia, erupting on August 29, 2010.* *Sinabung<http://scienceblogs.com/eruptions/2010/08/new_eruption_at_sinabung_in_in.php> * The Indonesian volcano continues to experience explosions<http://edition.cnn.com/2010/WORLD/asiapcf/08/30/indonesia.volcano.toll/?hpt=T2#fbid=BpenJRS5Ruh&wom=false>, which one last night (well, last night here in Ohio) that prompted an ash advisory for aircraft up to 6,100 m / 20,000 feet<http://volcanism.wordpress.com/2010/08/30/another-eruption-at-sinabung/>, although most reports I've seen pegged the ash column at closer to 2,000 m / ~6,500 feet. *Eruptions* readers have found a bevy of links for footage and information about the eruption, including a remarkable image gallery from the BBC <http://www.bbc.co.uk/news/world-asia-pacific-11126417> that shows the volcano exhibiting two ash plumes<http://www.bbc.co.uk/news/world-asia-pacific-11123559>- one that is vertical, one that is shooting off to one side (see above). This definitely makes it seem that the vent is partially blocked and these explosions are helping "clear the throat" of the volcano (NOTE: this does NOT mean I think something big is going to happen, rather just that it seems to be the reasonable explanation for the bifurcation of the plume). My hunch is that even now, very little "new" juvenile magma has been erupted from Sinabung, but that is pure speculation until there are any analyses of the ash shard morphology or composition. There is also some video from Portuguese television<http://tv1.rtp.pt/noticias/index.php?t=Vulcao-Sinabung-entrou-em-erupcao.rtp&headline=20&visual=9&article=371051&tm=7>Some of the most recent images from the volcano show a strong, single plume with some rock avalanches (possible block and ash flows) on the flanks.Evacuations have increased to over 21,000 people<http://www.dailymail.co.uk/news/worldnews/article-1307360/Flights-diverted-21-000-people-evacuated-Indonesian-volcano-continues-erupt-second-day.html>living near the volcano and some flights have been diverted due to the taller ash plume. The biggest threat right now is the ash fall from the explosions and as such, the government is providing face masks and moving people to sturdier shelter<http://af.reuters.com/article/worldNews/idAFTRE67S07K20100830>. The current death toll appears to be 8<http://www.dn.se/webbtv/nyheter/se-bilder-fran-vulkanutbrottet-pa-sumat%3Cbr%20/%3Era-1.1161621>( *video*), mostly from respiratory-related problems. What comes next might be a guess for everyone at this point as the Surono, head of the Indonesian Center for Volcanology and Geological Disaster Mitigation admitted again *"We don't know what set it off, how long it will continue or whether to expect pyroclastic flows or more powerful eruptions."*
