Due to Increased Seismic and Thermal Activity: Sernageomin Raises the Láscar Volcano to Yellow Alert

Summary by CNN Chile
The National Service of Geology and Mining (Sernageomin) raised the technical level of the Láscar volcano in the Antofagasta region from green to yellow alert after detecting signs of anomalous internal activity. As explained by the head of the National Volcanic Surveillance Network, Álvaro Amigo, to Radio DNA, seismic swarms associated with rock fracture and fluid movement were recorded during February, along with an increase in thermal radiati…

After evaluating the situation of the Láscar volcano, located in the Antofagasta Region, the National Geology and Mining Service (Sernageomin), determined to raise the volcanic alert from green to yellow level. According to the specialists, this decision is based on the fact that, during the last few weeks, there has been a sustained increase in volcanic-tectonic seismicity (associated with rock fracture), evidenced in the presence of different …

The Yellow Alert in the Láscar volcano was decreed after an increase in seismicity and gas emissions was detected; volcanologist Susana Layana of the Instituto Milenio Ckelar explained that the phenomenon responds to a phase of internal instability that does not necessarily imply an eruption. A sustained increase in volcanic-tectonic seismicity — that is, earthquakes associated with rock breakage and fluid movement inside the volcano — led the a…

The National Service of Geology and Mining (SERNAGEOMIN) decided to raise the technical alert level of the Láscar volcano from green to yellow, after detecting obvious changes in its internal and external activity. According to the Volcanic Observatory of the South Andes (OVDAS), during February and the first days of March seismic swarms were recorded and [...] This article Yellow Alert in the Láscar: They detect magma ascent and prohibit access…
