HVO, Civil Defense jointly track June 27 lava flow

The U.S. Geological Survey Hawaiian Volcano Observatory and Hawaii County Civil Defense are working closely together to gather and share information about the June 27 lava flow through daily helicopter overflights. Civil Defense Administrator Darryl Oliveira flies early each morning to measure the flow’s advancement and direction and to assess fire and smoke conditions. These observations are compiled in a report available to the public later the same morning at hawaiicounty.gov/active-alerts.

The June 27 flow advances toward Pahoa

In an Aug. 22 news release, the USGS Hawaiian Volcano Observatory stated that a new lava flow, dubbed the June 27 flow for the date it began, was rapidly advancing toward residential areas near Pahoa in the Puna District of Hawaii Island. By that time, the flow had entered a pre-existing ground crack, which channeled the flow to the east. The crack eventually filled and lava emerged from its lower end, only to spill into an adjacent crack. This process was repeated several times during the following days, with some ground cracks capturing and directing the flow, while others were filled as lava advanced across them. The average advance rate for the flow during this period was about 820 feet per day.
