Fluid basalt in a channelized ‘a‘a lava flow from the 1984 eruption...

Detailed Description

The vent erupting the greatest volume of lava is in upper right. By March 29, this channel fed an ‘A‘ā flow flow that reached 25 km from the vents; the channel width varied 20 to 50 m and extended to within 1 to 2 km of the flow front. In the morning on March 29, a blockage and overflow of the channel occurred about 12 km from the vents (1,800-m level) and took most of the supply away from this lower flow.
