To the ongoing concerns about activity at Kerinci and Krakatau, must be added new alerts for Slamet, Java’s second-highest volcano and one of its most active, and Paluweh (also known as Rokatenda) in the Lesser Sunda Islands, which last erupted in 1985. The Volcanology and Geological Disaster Mitigation Center (PVMBG) has raised the alert levels for both volcanoes from the lowest level of Normal to the next highest level of Yellow (Indonesian: Waspada).

Local news reports speak of a higher frequency of earthquakes at Paluweh, 23 per day up from an average of 2 per day in early April, while Slamet has apparently doubled its normal daily earthquake rate to 97 per day, a white plume has been rising to 300 metres above the crater, and water temperatures have risen.

Three volcanoes are currently on the second-highest alert level of Orange (Siaga) in Indonesia: Semeru, Karangetang and Ibu. Thirteen – including, now, Slamet and Paluweh (Rokatenda), are at Yellow (Waspada).
