Activity continues at the growing lava delta

Detailed Description

There were nice views of the 61g lava delta today (September 19) from the public viewing area. Many streams of lava were entering the ocean on the eastern side of the delta creating a robust plume. Over the past week, there have been repeated breakouts near the center of the delta, increasing its size. The delta size was roughly 10 acres (4 hectares), when measured using a satellite image of the delta taken on September 4.
