Sinabung volcano (Sumatra) - first pyroclastic flows from lava dome

The growing lava dome has started to produce (extremely dangerous) pyroclastic flows, as parts of the unstable mass of the viscous lava have now overtopped the crater the dome had been growing inside. The first series of 3 flows apparently took place this morning at dawn on the southeast slope and reached up to 1.5 km length. More pyroclastic flows occurred at 17:22 and 18:36 local time, reaching maximum run-out lengths of approx. 2.5 km. Valleys radiating from the volcano should be avoided at all times in distances up to many kilometers. During Merapi's deadly eruption in 2010, some flows reached lengths of over 20 km.

Dertig uitbarstingen op één dag

De Indonesische vulkaan Sinabung is al maanden onrustig. Vandaag was hier geen uitzondering op. Er werden 30 uitbarstingen waargenomen. Dit resulteerde tot nog meer evacuaties. Inmiddels hebben meer dan 20.000 mensen hun huis moeten verlaten. Tijdens de uitbarstingen van vandaag stroomde er rivieren van lava door een evacuatie zone en kolommen van as spoten tot 4km de lucht in. De lava komt tot zo'n vijf km ten zuidoosten van de krater. Deze uitbarstingen zijn de grootste van de laatste actieve periode. Er wordt overlegd of de evacuatie zone van 5 km moet worden uitgebreid.

Duizenden op de vlucht voor vulkaan Sinabung

De Indonesische vulkaan Mount Sinabung houdt niet op hete gassen en gesteente te spuwen. Dat meldt woordvoerder Sutopo Nugroho van de Rampbestrijdingsdienst. Sinds de vulkaan in september weer actief werd, zijn al meer dan 22.000 mensen ontheemd. Volgens de woordvoerder heeft de vuurberg "nog veel energie" en kan de uitbarsting "nog enige tijd duren". Sinds gisteren waren er meer dan twintig erupties.

Vele voor de vulkaan gevluchte mensen leven in armoedige omstandigheden in overheidsgebouwen en tijdelijke onderkomens in het district Karo in de provincie Noord-Sumatra, aldus hulpverleners. Minstens zeven vluchtelingen zijn om uiteenlopende redenen overleden, zoals hoge bloeddruk en ademhalingsproblemen. Voor de eerstkomende dagen is er voldoende voedsel voor de ontheemden, zei Nugroho. De 2.460 meter hoge vulkaan "sliep" 400 jaar, om in augustus 2010 uit te barsten. Op de Indonesische archipel zijn er bijna 130 actieve vulkanen.

Doden door uitbarsting vulkaan Sumatra

Zeker veertien mensen zijn omgekomen door een uitbarsting van de vulkaan de Sinabung op het Indonesische eiland Sumatra. ''Waarschijnlijk vinden we nog meer doden'', zei een priester op het eiland die nauw met een hulporganisatie samenwerkt zaterdag. De autoriteiten hadden juist deze week geëvacueerde bewoners van dorpen op meer dan 5 kilometer afstand van de vulkaan toestemming gegeven naar huis terug te keren.

Sinabung volcano (Sumatra) - series of pyroclastic flows kill at least 14 people



Sad news today: the volcano claimed its first victims this morning due to a direct effect of the eruption. At least 14 people were reported killed and 3 others severely bunt by one or two moderately large pyroclastic flows this morning. 3 more people are still reported missing. According to Jakarta Post all fatalities that could be located so far had occurred in Suka Meriah village, which is located within a 3-kilometer radius of the volcano, thus in well in the exclusion zone. However, during the past days, enforcement of the exclusion zone had been loosened, and according to some sources, people had even be formally allowed to return to their homes,- a fatal decision for some. Among the fatalities were several school children and students. Rescue operations were affected by fears of new pyroclastic flows.

According to BNPB spokesman Sutopo Purwo Nugroho, there were three eruptions: the first eruption occurred at 10:30 a.m. (local time) and lasted for eight-and-a-half-minutes, generating a 4.5 km long pyroclastic flow, while the second followed immediately after at 10:38 a.m. and lasted just over four minutes, followed by a third one at 11:27 a.m. for 84 seconds. It is not exactly clear where the pyroclastic flow originated, from explosions at the summit, collapse of the summit lava dome, or from (partial collapse) on the viscous flow that had recently been emplaced. The latter two scenarios are the more likely ones. Webcam images don't show much detail except a dense ash plume engulfing the southern slope.

Zware uitbarsting veroorzaakte tornado's

Door de zware uitbarsting van de Sinabung vulkaan zijn er tornado's ontstaan. De bewegende pilaren van as en lucht worden veroorzaakt door de pyroclastische stroom. De lucht boven de gloeiend hete massa wordt verhit. De desastreuze combinatie van gesmolten gesteente en gloeiend hete (draaiende) lucht vormt een spoor waarbij alles in het pad vernietigd wordt.
