On Tuesday, July 9 at 5:50 am local time (09:50 UT 9 July), the control stations installed near the Volcanic Complex Nevados of Chillán recorded an explosive event, associated with the occurrence of a long-term earthquake (LP), related to fluid dynamics within the volcanic system. -
The LP earthquake was located as follows: Latitude: 36.863 ° - Longitude: 71.377 ° - Depth: 1.3 km
The explosion is associated with the recording of a seismic signal with a reduced displacement value (measured seismic energy) of 587 cm2 considered high. Likewise, an incandescence associated with a high temperature emission of gas and pyroclastic material has been observed which has deposited in the zone close to the active crater.
The technical alert remains orange.

The Geophysical Institute of Peru (IGP) reports that the eruptive activity of the Sabancaya volcano has remained at moderate levels between July 1 and July 7.
The analysis of recordings obtained from the seismic network of the Sabancaya volcano for the same period has identified about 2228 earthquakes of volcanic origin, most of them associated with the movements of magmatic fluids.
An average of 23 daily explosions of low intensity are reported. Visual surveillance, using surveillance cameras, allowed identify the presence of gas columns and ash up to 3.7 km high at the top of the volcano (2 on July 2019), whose ashes were dispersed in E, SE and NE sectors of Sabancaya (Colca Valley, Yura).
Monitoring the deformation of the volcanic structure using GNSS data (processed with fast orbits), does not show significant anomalies. The satellite monitoring identified 13 thermal anomalies with values between 1 and 23 MW, associated with the presence of a hot body near the surface and the appearance of continuous explosions.
In alert level Orange, it is recommended not to approach within a radius of less than 12 km from the crater.

Wandan mud volcano erupted yesterday, July 8, in a field adjacent to the site of last year's eruption in Pingtung County / Taiwan.
The mud was emitted over one meter in height and was accompanied by flames when the natural gas causing the eruptions ignited.
Fortunately for the affected farmer, the field had already been harvested, but the Wandan County Government immediately sent an excavator to divert mud from nearby cropland. Farmers expressed the hope that the government would put in place a subsidy system for farmers affected by eruptions. The mud that had accumulated during last year's eruption had still not been cleaned and the adjacent field is now flooded with mud.
The Wandan Mud Volcano occurs periodically at intervals of six months to two years at different locations within a radius of about two kilometers near the border of Wandan and Xinyuan Townships.
Before yesterday's eruption, the last eruption occurred on December 24, 2018.
