Fernandina Volcano, Galapagos Islands - John Seach

A new eruption began at Fernandina volcano on 10th April 2009 at 2200 hr. The seismic station at Puerto Ayora did not record any earthquakes associated with the eruption. The eruption was observed by rangers from Galapagos National Park, and a tourist boat in the early hours of Saturday morning (local time). An eruption column with low ash content was visible on satellite images extending 300 km west of the volcano. Satellite images show several hotspots at Fernandina volcano, which may indicate lava flows. Personnel from the Galapagos National Park on Isabela Island are making a flight over the volcano, to ascertain more precisely the location of the eruption centre, and assess the extent of the lava flows and their likely impact
fauna and flora of the area. The last eruption of Fernandina volcano occurred in 2005, when lava flows originated from a fissure on the south-eastern flank of the volcano and descend without reaching the sea.
