Activity of Pacaya, Nevado del Ruiz and Sheveluch.

In Guatemala, Insivumeh continues to observe weak to moderate explosions in the Pacaya on October 13, with projections 75-150 meters above the Mackenney crater, and a plume of gas and steam in a westerly direction at low altitude.

The lava flow on the northern flank is reported with a length of 250 meters.

Tremor is recorded associated with the ascent of magma, and movements of gas and lava flow.

In Nevado del Ruiz, the seismicity generated by the fracturing of rocks increased in number of earthquakes and in energy released compared to the previous week.

A few "drumbeat" type episodes associated with low energy fracturing have been recorded. They are associated with the process of evolution of the dome of the Arenas crater.

Seismicity linked to the dynamics of internal fluids is also on the rise.

The SGC does not report significant changes in surface deformation.

The gas and steam plumes reached heights of up to 1,350 meters above the summit.

The level of activity remains amarillo.

In Kamchatka, the new dome of Sheveluch continues to grow, with these October 12 and 13, a strong emission of fumaroles, and an incandescence of the blocks that make it up.

A thermal anomaly was spotted by satellite, going up to VRP 61MW on October 13 at 00:40.
