Live seismograms
Seismograph (helicorder) records from the last 24 hours at 3 PVMBG stations on Mount Tambora, updated about every 15 minutes. One line = 30 minutes; the bottom line is the latest. Times on the image are UTC (WIB = UTC+7, WITA = UTC+8, WIT = UTC+9). Click an image for full size.
Source: PVMBG – MAGMA Indonesia. Volcanic earthquakes appear as spikes on the trace; continuous shaking may indicate tremor.
Volcanic hazard map (KRB)
Official Geological Agency map (2008): areas that may be hit by pyroclastic flows, lava flows, ballistic rocks, ashfall, and lahars. KRB III is closest to the source.
