Volcanic activity in Chile

Volcanic activity in Chile

Seismic activity under volcanos in Chile has recently begun to increase causing Chile to raise its volcanic alert level to “yellow”. The area of concern is located around Cerro Hudson, in the southern Andes. 

Seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time. The frequency of volcanic quakes in Chile increased from 10 during August and September to 70 in November. During November, phases of tremor and so-called hybrid earthquakes, which represent magma movements have also been occurring. Usually safety alerts will change due to an acute change but this time the alert came because of these accumulated events. Chile’s ONEMI (Oficina Nacional de Emergencias) and SERNGEOMIN (Chilean Geological Survey) have set up a 3.5 kilometer exclusion zone around the volcano; a response that is informed by the last eruption of Hudson in 2011. The 2011 eruption, though a smaller eruption, opened three new vents on the volcano, indicating why this recent seismic activity needs to be closely monitored.

Ambience Data’s hardware devices, specifically our Starling, can monitor and transmit data instantly regarding seismic activity.
Seismologists, who study geophysics and the creation and propagation of seismic waves in geological materials, will be able to access this data to inform their work on earthquake geology, paleoseismology, tectonic geomorphology, near-field geodesy, earthquake response, salton seismic imaging. In fact, our Starlings are able to observe very small-scale earthquakes and conduct microseismic monitoring. These small-scale quakes occur as a result of human activities such as mining, hydraulic fracturing, enhanced oil recovery, geothermal operations.
Seismologists aren’t the only ones who will be able to check out this data though! Once a device is installed, data from our devices is accessible via our web-based dashboard or our app.
