Activity of Karymsky, Sinabung, Lewotolok, and Fagradalsfjall.

In Karymsky / Kamchatka, moderate eruptive activity of the volcano continues. According to satellite data from KVERT, an ash emission continues continuously. The explosions send ash up to 1,600 m. a.s.l. and the ash plume extends 52 km east of the volcano.

Moderate eruptive activity of the volcano continues. Ash explosions up to 6 - 7 km altitude could occur at any time. The current activity could affect low-flying aircraft. The aviation code remains orange.

An eruptive episode occurred at Sinabung on July 28, 2021 at 1:20 p.m. WIB / 6:20 a.m. UTC, accompanied by a gray and thick ash plume observed at ± 4,500 m above the summit (± 6960 m above the level of the sea). This eruption was recorded on a seismograph with a maximum amplitude of 120 mm and a duration of 742 seconds.

The VONA went from orange to red on July 28 / 06h34Z.

The Sinabung remains in activity level 3 / siaga, with no-go zones of 3 to 5 km distance depending on the directions.

At Ili Lewotolok, the PVMBG reports for the day of July 27, a plume of color varying from white to black at a height of 80 to 400 meters above the summit.

Seismicity of July 27 is characterized by:
- 5 eruption earthquakes, with an amplitude of 7 to 23 mm and a duration of 17 to 38 seconds.
- 3 blast / emission earthquakes, with an amplitude of 4 to 8 mm and an earthquake duration of 16 to 28 seconds.
- a non-harmonic tremor episode, with an amplitude of 6 mm and an earthquake duration of 71 seconds.
- 2 deep volcanic earthquakes.
In activity level 3 / siaga and aviation code orange, it is recommended that communities around Mount Ili Lewotolok as well as visitors / climbers / tourists not engage in activities within a radius of 3 km from the summit / crater of Mount Ili Lewotolok.

On July 28, an eruptive episode occurred at 00:24 WITA with an ash plume observed at ± 1,000 m above the summit (± 2,423 m above sea level). This eruption was recorded on a seismograph with a maximum amplitude of 45 mm and a duration of 49 seconds.
Another episode followed at 07:22 WITA, accompanied by an ash plume observed at ± 800 m above the summit (± 2,223 m above sea level) recorded on a seismograph with a maximum amplitude of 34 mm and a duration of 29 seconds.

At Fagradallsfall, we note the partial collapse of a section of the internal wall of the crater of the active cone on July 27.

The periods of activity alternate with that of calm, as evidenced by the tremor.
