On 10 October 2011, a submarine volcanic eruption started 2 km south from El Hierro Island (Spain). Since July 2011 dense multiparametric monitoring network was deployed all over the island by Instituto Geográfico Nacional (IGN). By time started, almost 10000 earthquakes had been located and deformation analyses showed maximum of more than 5 cm. Earthquake migration north to acceleration seismicity are in good correlation with changes pattern as well some anomalies geochemical geomagnetic...
Textures, petrography and geochemical compositions of products emitted during the onset 2011–2012 submarine eruption (15 October, 2011) off coast El Hierro have been investigated to get information on interaction mechanism between first rising magma crust as well storage plumbing systems beneath volcano. Studied consist 5–50 cm bombs with an outer black greenish, vesicular bulk basanite composition containing pumiceous xenoliths (xenopumices). Our results show that xenopumices are much more...
Abstract Volcano observatories (VOs) around the world are required to maintain surveillance of their volcanoes and inform civil protection aviation authorities about impending eruptions. They often work through consolidated procedures respond volcanic crises in a timely manner provide service community aimed at reducing potential impact an eruption. Within International Airways Watch (IAVW) framework Civil Aviation Organisation (ICAO), designated State Observatories (SVOs) asked operate...
Abstract São Miguel Island comprises five active volcanic systems, including three central volcanoes with calderas and two basaltic fissure systems. Volcanic eruptions in are of trachytic nature ( s.l. ), Hawaiian, Strombolian, sub-Plinian, Plinian Vulcanian events, the more explosive ones frequently hydromagmatic phases. Large related to caldera-forming events that occurred past. With reference Fogo A stratigraphic marker, a total 73 individual have been identified last 5 ka, giving...
<p>Last year's almost 3-month eruption on the island of La Palma was a Strombolian eruption. The explosive behaviour has been very variable and significant throughout  The IGN (Instituto Geográfico Nacional) measured height eruptive column from first days using visual cameras. main camera used one IAC Astrofísico de Canarias), located at 2365 masl altitude 16.5 km north vent. cameras were calibrated with geodetic techniques to check...
Abstract Between 2011 and 2014 there were at least seven episodes of magmatic intrusion in El Hierro Island, but only the first one led to a submarine eruption 2011–2012. In order study relationship between GPS deformation seismicity during these episodes, we compare temporal evolution with cumulative seismic energy released. some both evolve very similar way, others time lag appears them, which precedes seismicity. Furthermore, linear correlation decimal logarithm intruded magma volume...
