Mount Sinabung Erupts

Lava spewing ‘like a ball of fire’

Indonesian officials have issued a red alert after Mount Sinabung on the island of Sumatra began spewing lava early Sunday morning.

The volcano had been spewing smoke and ash to a height of about 1.5km a.s.l. throughout Saturday, local reports said, quoting  eye witnesses who saw lava spewing out of the volcano from 7 km away.

The authorities have evacuated up to 15,000 residents living near the volcano.

Mount Sinabung is one of Indonesia’s 130  active volcanoes, and had last erupted about 400 years ago.

The head of Indonesia’s vulcanology center was quoted by Reuters as saying:

“This is the first time since 1600 that Sinabung erupted [although there are no activities recorded] and we have little knowledge in terms on its eruptive patterns and general forms.”

Many prominent lava flows appear on the flanks of the volcano. No confirmed historical eruptions are known from Gunung Sinabung. Photo by Tom Casadevall, 1987 (U.S. Geological Survey). Caption: GVP

The volcano is located about 260km east of the epicenter of the 9.1 – 9.3Mw earthquake which struck off the coast of Sumatra on December 26, 2004, triggering the deadly Boxing Day Tsunami.
