Space-Time Forecasting of Seismic Events in Chile

2017

The aim of this work is to study the seismicity in Chile using the ETAS (epidemic type aftershock sequences) space‐time approach. The proposed ETAS model is estimated using a semi‐parametric technique taking into account the parametric and nonparametric components corresponding to the triggered and background seismicity, respectively. The model is then used to predict the temporal and spatial intensity of events for some areas of Chile where recent large earthquakes (with magnitude greater than 8.0 M) occurred.

Gas fluxes and compositions of two active volcanoes in Northern Chile: Lascar and Lastarria

2013

The Central Andes Volcanic Zone of northern Chile comprises a ~1200 km long volcanic district extending from the Atacama region on the northe to the Arica and Parinacota region.Lascar and Lastarria are among the most actively degassing volcanoes of the several (more than 30) potentially active in the region. They both host persistent fumarolic fields and generate sustained plumes above the main craters. Here, we report on simultaneous in-situ and remote volcanic gas measurements aimed at obtaining the very first degassing budget for major volatiles released by these fumarolic fields. Using quick deployable scanning DOAS and SO2 camera systems we obtained time-averaged SO2 fluxes of ~ 500 t …
