The activity throughout 2005 marked the highest levels yet. The increase in activity in the fall of 2005 produced an active -long lava flow, extending from the summit cone of Mount Belinda to the sea. The flow spread northeast from the volcanic vent, and then became diverted due north by an arête. By late 2007, eruptive activity had ceased, and in 2010 the only activity was from scattered fumaroles and cooling lava.
