At the Sinabung on Sumatra the situation comes to a head: here the seismicity increased enormously in the last days and not only debris avalanches were registered, but above all earthquakes with low frequencies. They indicate massive magma rise. Yesterday, a good 560 of these quakes were recorded. In the first 6 hours of today, there were already 239 quakes. In addition, 112 signals testified to debris avalanches. The dome is growing and the situation is becoming more and more critical!
