People in and around Pahoa will meet with the state and scientists to talk about the risks of a new flow.
Video from a meeting Monday night showed the room was packed with anxious residents, waiting to hear the latest on the June 27 lava flow, named for the day it began erupting from a new vent.
The lava has been moving slowly through large cracks, primarily underground, which makes it's path hard to predict.
It’s (going to) be very difficult to forecast exactly where this is going to go, especially if the lava is going to come out of one crack and flow into another,” Jim Kauahikaua said.
Darryl Oliveira with Hawaii County Civil Defense said the is available to help.
“Any community that may be affected by an approaching eruption or lava flow, we will work with you on the evacuation, as well as to secure your community, so you if you want to move, and (don’t want to) be interrupted by those taking pictures or sightseeing.
In addition to Tuesday’s meeting, there will be another opportunity for residents to get information at Pahoa Community Center at 6:30 Thursday.
