How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Several areas of science have been assigned a UN-recognised day for the field (e.g., World Meteorological Day, World Tsunami Awareness Day, World Oceans Day); however, such a day is presently lacking for seismology. In preparation for a “Seismology Day”, we would like to gauge the degree of support within the seismology community and increase momen...
Villarrica volcano is the most active and hazardous volcano in the southern volcanic zone in the Chilean Andes. Most of the volcanic edifices in the Southern Volcanic Zone are emplaced along the arc-parallel 1000-km long Liquiñe-Ofqui Fault Zone (LOFZ). For Villarrica volcano, the emplacement falls at the intersection with the NW striking Villarric...
The seismicity of Villarrica volcano is compared before and after the Maule earthquake (Mw 8.8, 2010), and the inner seismic structure is obtained through tomography.
Abstract: Chile is one of the seismically most active countries in the world with an earthquake of magnitude 8 or larger (M ≥8) occurring every 10 years. The most recent 27 February 2010 (Mw =8.8) earthquake released the energy accumulated in the Concepción–Constitución seismic gap contained since the last earthquake in 1835. The hypocentre (36◦17...
Llaima and Villarrica are two of the most active volcanoes in the Chilean Southern Volcanic Zone and presently show contrasting types of activity. Llaima is a closed vent edifice with fumarolic activity, while Villarrica has an open vent with a lava lake, continuous degassing and tremor activity. This study is focused on characterizing the relation...
Llaima and Villarrica are two of the most actives volcanoes in the Southern Volcanic Zone in the Chilean Andes, with different type of activity and edifice. Llaima is a close vent volcano with constant seismic activity, while Villarrica is an open vent volcano with lava lake at the summit and constant degassing. The relation between volcano eruptio...
Villarrica is one of the most active volcanoes in Chile and is presently characterized by activity from open continuously degassing conduit. The twohundred meter diameter crater contains a persistent lava lake which has a diameter of approximately ten meters. For the quantification of SO2 fluxes three stationary NOVAC-type scanning Mini-DOAS UV spe...
Villarrica is one of the most active volcanoes in Chile and is presently characterized by continuous degassing, high-level seismicity and a persistent lava lake within its crater. Three stationary NOVAC-type scanning Mini-DOAS UV spectrometers for the quantification of SO2 fluxes were installed at the volcano in March 2009. Seismic stations used fo...
We relocated the six large-magnitude (5.2 < Mw < 6.2) earthquakes of the destructive, tsunamigenic Aysen seismic swarm, which occurred from 2007 January-October in Patagonian Chile. We used P and SH arrival times from near-source stations of a temporary seismic network fortuitously deployed in the area when the swarm began, and also traveltimes to...
A seismic swarm at the Aysén fjord started in January, 2007, reaching its highest activity between January and April, 2007. It was punctuated by the Mw5.3 23rd January event and the Mw6.2 21st April event which triggered a water-wave due to massive landslides; both with dextral strike slip focal mechanisms. More than 100 events were relocated with...
Aysen Fjord is situated on one branch of the Liquiñe Ofqui Fault Zone (LOFZ), in southern Chile, a dextral intra-arc strike-slip megafault approximately 1000 km long, spatially related to the North Patagonian Batholith and the current volcanic arc. This fault is characterized by strain partitioning which in this region is due to dextral shear stres...
