Western Indonesia’s Mount Sinabung has been placed on high alert for what is being called a “mega-eruption” for several km/miles around the volcano.
Video reports coming out from the region show ash, steam, and eruptive blasts currently occurring.
In addition to the large eruption at Mount Sinabung, we now have other reports that the nearby Toba supervolcano is showing large emissions of steam (from the ground), as well as foul smelling gas.
According to reports from Indonesian press, locals are alarmed by these recent developments.
Toba supervolcano is indeed a “super-volcano” by all measurements. Actually LARGER in eruptive power to the other more well known “Yellowstone” super volcano (located in Wyoming / United States).
Worthy to note, the Toba caldera produced the worlds largest eruption in the past 2 million years, and has not showed eruptive signs in over 75,000 years.
From Oregon State University:
“Toba caldera produced the largest eruption in the last 2 million years. The caldera is 18 x 60 miles (30 by 100 km) and has a total relief of 5,100 feet (1700 m).
The caldera probably formed in stages. Large eruptions occurred 840,000, about 700,000, and 75,000 years ago. The eruption 75,000 years ago produced the Young Toba Tuff. The Young Toba Tuff was erupted from ring fractures that surround most or all of the present-day lake. “
“About 74,000 years BP, more than 2500 cubic kilometers of magma were erupted. The eruption led to the final formation of one of earths largest calderas, the 35×100 km wide Toba caldera. Eruptions of this size are exptremely rare and are called supervolcano-eruptions. The Toba caldera is in fact the Earth’s largest Quaternary caldera.
It was formed during four major Pleistocene ignimbrite-producing eruptions beginning at 1.2 million years ago and culminating with the colossal Young Toba Tuff (YTT) eruption about 74,000 years ago. The YTT emplaced about 2500-3000 cu km (dense rock equivalent) of ignimbrite and airfall ash from vents at the NW and SE ends of present-day Lake Toba.”
