The recent seismic crisis could be over: No further significant earthquake activity has occurred since the last pulse on Wednesday. It becomes more and more likely that the crisis (or, if that is was what caused it, the magmatic intrusion under western El Hierro) has ended. ...

Typical eruption style: mainly effusive, basaltic fissure eruptions El Hierro volcano eruptions: 2012 (?) (probable second submarine eruption in June-July west of the island), 2011-12 (Oct-Mar, submarine eruption near La Restinga), 1793 El Hierro Volcano Photos Last earthquakes nearby:
Following intense earthquake swarms since July 2011, a new submarine eruption started in Oct 2011 at a vent ca. 1 km south of La Restinga off the southern tip of the island. The eruption, which could even start to build a new island, is ongoing at the time of updating. Follow the El Hierro news page for the latest events. Background:The massive El Hierro shield volcano is truncated by a large NW-facing escarpment formed as a result of gravitational collapse of El Golfo volcano about 130,000 years ago. The steep-sided 1500-m-high scarp towers above a low lava platform bordering 12-km-wide El Golfo Bay, and three other large submarine landslide deposits occur to the SW and SE. Three prominent rifts oriented NW, NE, and south at 120 degree angles form prominent topographic ridges. The subaerial portion of the volcano consists of flat-lying Quaternary basaltic and trachybasaltic lava flows and tuffs capped by numerous young cinder cones and lava flows. Holocene cones and flows are found both on the outer flanks and in the El Golfo depression. El Hierro contains the greatest concentration of young vents in the Canary Islands. Uncertainty surrounds the report of an historical eruption in 1793 at Volcano of Lomo Negro. Source: Smithsonian GVPEl Hierro Photos:
