June 27 lava flow advance rate increases...

Detailed Description

The June 27 flow front has advanced more rapidly over the past four days, and is now 4.2 km (2.6 miles) from the vent. This recent increased advance rate is due to the confinement of the flow against the slopes of an older perched lava channel, from 2007. The advance rate will likely drop in the coming days as the flow passes the confines of the perched channel and spreads out on flatter topography.
