Detailed Description

A remarkable perched lava pond was active on the June 27 lava flow more than a month ago. On August 12 a small lava flow erupted from the rim of the inactive pond, with the flow presumably originating from fluid lava that remained in the perched pond interior. This type of flow is commonly erupted from perched lava ponds and small lava shields, and we informally refer to these as "seeps". The seeps have a characteristic spiny, toothpaste-like, flow texture. Today, this seep was inactive, but the flow interior remained incandescent. The front of this small flow can be seen at the top of the photograph.
