<p>A shallow water eruption started on October 10, 2011, ~2 km south off the coast of El Hierro (Canary Islands, Spain). The lasted about five months and ended by early March 2012. Three unrest preceded this event with more than 10,000 localized earthquakes up to 6 cm vertical ground deformation. In Canary is first be monitored network Instituto Geográfico National (IGN) since very beginning seismic unrest. This provided unprecedented time series that include geophysical (seismic...
Abstract We reanalyzed the seismic and deformation data corresponding to preeruptive unrest on El Hierro (Canary Islands) in 2011. considered new information about internal structure of island. updated catalog estimate full evolution released energy demonstrate importance nonlocated earthquakes. Using GPS displacements, we characterized shear‐tensile type predominant fracturing modeled strain stress fields for different time periods. This enabled us identify a prolonged first phase by...
Abstract The 2011–2014 volcanic activity at El Hierro (Canary Islands) was characterized by a 5‐month long submarine eruption as well series of magmatic intrusions occurring between 5 months and 2 years after the eruption, revealed seismic swarms ground deformation. We study temporal evolution six post‐eruptive intrusions, using Global Navigation Satellite System Interferometric Synthetic Aperture Radar observations complemented with relocated earthquakes. Magma volumes magma supply rates...
