Klyuchevskoy - KVERT archives 31.01.2020

A moderate explosive eruption of Klyuchevskoy continues; strombolian activity is observed. According to satellite data, a plume of gas and vapor containing a certain amount of ash stretches over 120 km, then 84 km respectively towards the ESE and then to the east of the volcano.
This explosive activity continues. Ash explosions up to an altitude of 5-7 km could occur at any time. The current activity could affect aircraft flying at low altitude.

The aviation code remains orange.

A short-lived episode of volcanic earthquakes occurred under Mount Ruapehu from Saturday February 22 to Sunday February 23. The earthquake episode is over.

The most important events, at the start of the episode, have a magnitude of about 1.5 and later, the smaller events are too small to be located by GeoNet's earthquake tracking and detection system.

Seismic records indicate a source below the summit area, which is normal for volcanic earthquakes and volcanic tremors in Ruapehu. The sequence now seems to be over.

The temperature of Te Wai Crater Lake at-moe has been around 24-25 ºC in recent months.
