Twenty Indonesian volcanoes ‘ready to erupt’? (updated) 1 October 2010Posted by admin in activity reports, Indonesia, volcano monitoring.
[UPDATE. The Jakarta Globe story has moved here, and the number of volcanoes allegedly ‘ready to erupt’ has increased to 21. The article lists three volcanoes at alert level 3 and eighteen at alert level 2. The latter group is as listed below with the exception of Seulawah Agam, which is omitted for some reason. The article has been extended, but remains a complete non-story from start to finish. It also remains utterly dumb.]
‘Volcano observation experts are warning that twenty volcanoes across the archipelago are ready to erupt’ – that’s what it says [new location for the story here] in the Jakarta Globe, anyway. According to the Globe‘s report, the head of the Indonesian Institute of Volcanology and Mitigation of Natural Disasters has ‘raised the volcanic activities status of 17 volcanoes in Indonesia, from “normal, or level 1” to “beware, or level 2”.’ Three more volcanoes — Sinabung, Ibu and Karangetang — are on higher levels of alert.
However, according to the Volcanological Survey of Indonesia (VSI) website, 20 volcanoes are on level 2 (yellow) anyway, with Merapi and Seulawah Agam being the most recent to have had their alert levels raised. Karangetang and Ibu are on level 3 (orange), as is Sinabung, where the alert level has just been lowered from level 4 (red). Many of the volcanoes on level 2 have been there for two or three years.
So it’s far from clear just what that Jakarta Globe article is all about.
