Detailed Description

A methane explosion in the ground adjacent to the flow margin threw these blocks of older lava, some up to half a meter (yard) in diameter, a distance of several meters (yards) onto the flow surface. Just to the left of the geologists is a crater of disrupted ground, with overturned blocks of older lava up to a meter (yard) in size. Methane explosions are a hazard in the immediate vicinity of the flow margin. More about methane bursts can be found at https://volcanoes.usgs.gov/observatories/hvo/hvo_volcano_watch.html?vwid=731.
