New volcanic eruptions: Karangetang and Merapi (Indonesia), Planchon-Peteroa (Argentina-Chile), Shiveluch (Russia) – 4th eruption of Steamboat Geyser in 2019 (Yellowstone National Park)

Karangetang, Indonesia

The eruption at Karangetang volcano continues with lava pouring down the slopes towards the ocean, and 200 meters only from the coastal road.

Pyroclastic flows go down the slope of the Indonesian volcano.
Satellite pictures confirm the lava flow… Almost into the sea:

Merapi, Indonesia

Block collapses and flows of incandescent lava chunks continue at Merapi volcano.

Planchon-Peteroa, Argentina and Chile

The column of ash and gas ejected by the Planchon-Peteroa Complex is increasing and now reaching continuously 1,500 meters above the crater.

The energy of the seismic signals has also been rising since February 1st.

Young material has been found in ash samples. This indicates that the body of magma is rising and starts interacting with the hydrothermal system. A
hydromagmatic eruption may be on its way.

The technical alert remains amarillo.

Shiveluch volcano, Russia

The explosive-extrusive eruption of the Shiveluch volcano continues in the Kamchatka Peninsula, with a strong eruption sending ash up to 4000 meters above the crater on February 3, 2019.

According to satellite data, a gas-steam plume with some amount of ash continues to drift to the south-west from the volcano. Ash explosions up to 32,800-49,200 ft (10-15 km) a.s.l. could occur at any time.
The growth of the lava dome continues. This process is accompanied by a strong fumarolic activity and hot debris avalanches.

Steamboat Geyser, Yellowstone National Park

The USGS reports the fourth eruptive episode of the Steamboat geyser in 2019. Eruptions occurred on January 4 at 16:19, January 16 at 7:12, January 25 at 12:32 and February 1 at 13:21.
