An AP video report here in German reports on the biggest Merapi eruption in 100 years, and what potentially lurks.
More than 122 people have been killed thus far as the volcano continues to blast clouds of ash into the atmosphere. Over 200,000 people have been evacuated from the area so far. Experts are uneasy. At the 3o sec. mark, the AP video reports:
In the meantime, speculation of a possible gigantic eruption is making the rounds. Although Merapi does not show it, there’s a risk of a mega-eruption at any time. A collapse of the mountain could cause movement of the huge magma reserve underneath. If the heavy rock mass above it were to disintegrate, the magma would be freed and could be blown out. But no expert wanted to make an exact prognosis.
As reported earlier here at this blog, experts estimate that a reservoir of magma three times the size of what was ejected by the mighty Tambora eruption of 1815 remains trapped under immense pressure underneath Merapi. Tambora had a Volcanic Explosivity Index (VEI) of 7 and led to global cooling, the year without a summer.
For now, it’s wait and see with Merapi.
The following video shows what kind of ticking “time bombs with hidden timers” that lurk beneath us.
