The volcanic activity is increasing across Indonesia.

In addition to Mount Merapi (Central Java) and Mount Semeru (East Java), two more volcanoes are now erupting in Indonesia: Sinabung (Sumatra) and Raung (East Java).

Sinabung volcano eruption

Mount Sinabung, situated in Karo District, North Sumatra Province, erupted again, spouting hot cloud and incandescent lava as far as two kilometers in the air on February 12, 2021.

The volcano also spewed hot cloud to a height of approximately one kilometer toward the east, southeast, and south of Mount Sinabung. The eruption had an amplitude of 120 mm, while the earthquake’s duration was 159 seconds.

The emergency status of the 2,460-meter-high Mount Sinabung was updated to Level III (alert).

Residents and farmers were asked to steer clear from conducting activities in villages that have been relocated and at locations within a three-km radius from the mountain’s peak, five-km radius for the south-east sector, and four-km radius for the east-north sector.

Since it’s raining right now, the danger of lahar is high. This is what happened at Semeru volcano (East Java) just 2 days ago… Apocalyptic:

People residing by the rivers close to Mount Sinabung were also urged to remain alert to the dangers of lava.

After being inactive for four centuries, Mount Sinabung has sprung back to life since 2010 and has erupted sporadically. Tens of thousands of people have been displaced by the natural disaster.

Raung volcano eruption

The explosive eruption of the volcano continues at elevated levels.

A series of stronger explosions occurred during the past 2 days as emissions of steam and ash generated by the explosions reached up an higher-than-usual altitude of approx. 18,000 ft (5,500 m) and extended to the E-SE.

Frequent steam glow continues to be active and visible from the summit crater at night. Glow suggests continued rise of fresh magma that could be rising inside the volcano’s conduits.

The warning bulletin states that ballistic impacts of volcanic bombs could affect an area of about 2 km distance from the main crater.

Other eruptions around the world: Pacaya and Etna, Sakurajima and Kazakhstan amont others…

    Nothing worse than some flaming hot chunk of volcanic rock hitting your house.
