Roundup of Global Volcanic Activity:
Sinabung (Sumatra, Indonesia): The volcano's eruption remains essentially stable. The volcano continues to produce frequent pyroclastic flows - avalanches of lava rocks and ash mixed with gas and air, triggered by partial collapses of the growing lava dome. They continue to reach 2-4 km lengths and run down the SE slope where an extensive delta of pyroclastic deposits is formed. The flows reach lengths of 2-4 km, but the risk of larger flows that would threaten the village in the foreground remains high. The exclusion zone in this area is 7 km from the summit.
San Miguel (El Salvador): Chaparrastique (the local name of the volcano) is still restless. SNET reports seismicity at (low) levels similar to before and after the eruption on 30 Dec, and a degassing plume of 100 m height, with a decreasing tendency. However, new eruptions with little or no warning could occur and authorities ask people not to approach the crater.
