Review of the seismic event related to an explosion of the complex crater of the Chilean Nevado de Chillán | national



The seismic event associated with an explosion on Friday night was in the Crater of the Chillán volcano, in the Ñuble region.

According to Onemi, at 10:11 p.m., the Behanka Vulcanological Observatory, in the Southern Andes, Ovdas destroyed a massive lava at the foot of the volcano.

The explosion is associated with the recording of a seismic signal, the low displacement value (measured seismic energy).

Gas emissions and high-temperature pyroclastic material were also emitted, and part of this material was in the area of ​​active craters.

This would be the destruction of some lava dome that is growing in the Navaor crater for some time.

This situation allows the Yellow Warning System of Civil Protection to be maintained in Pinto, Coihueco and San Fabian, in the Ñuble region, due to the activity of the Volcanic Areas of Chillán.

The National Geological and Mining Services maintains its technical level at the Naranjo level.

It should be noted that after this event other uneconomical signals have been recorded. Likewise, this event is indicated in the current warning levels.

Today he flies over the mountain to discover the displacement of the magma.
