Alert level raised at Ijen, Indonesia 13 March 2012Posted by admin in activity reports, Ijen, Indonesia.
VolcanoDiscovery reports that the alert level for Ijen volcano in eastern Java, Indonesia, has been raised to level 3, ‘alert’ (the second-highest level) because of an increase in activity. Ijen’s alert level was last raised to 3 in December 2011, but was lowered to 2 in February. Concern about increased seismicity and degassing led Indonesia’s geological and hazard mitigation authority, PVMBG, to raise the level to 3 again on 12 March.
