Lava Covers First PGV Well

Hawai`i County Civil Defense reports that as of its 6 p.m. update, the lava flow from Fissures 7 and 21 that crossed into Puna Geothermal Venture property overnight and has now covered one well that was successfully plugged.

Civil Defense officials say that the well, along with a second well 100 feet away are stable and secured. They are both being monitored.  Also due to preventative measures, neither well is expected to release any hydrogen sulfide.

The special task force headed by Tom Travis continues to work to make the wells safe and to prevent any threats to the public from developing, according to the county.

There is no hydrogen sulfide detected despite the covering of the one well.

Due to changing wind conditions, gases and vog emissions may increase in areas down wind of the vents in the lower east rift zone. The following policies are in effect:

  • Take action to limit further exposure to volcanic gases and be prepared to leave the area with little to no notice.
  • Due to southerly winds and heavy output of vog from the summit on Monday night, be prepared for a possible increase in vog and volcanic gas levels in the Hamakua area, lower Hilo and Puna.
