Hawaii Volcanoes National Park has announced several nighttime closures on Kilauea due to increased seismic activity in the area.
All backcountry trails between Crater Rim Drive and the coast have been closed at night, as well as Kulanaokuaiki campground, due to an increase in seismic activity along the East Rift Zone.
No permits will be issued for the area until further notice.
The increase in seismicity and the drop in the summit lava lake — now about 10 meters, or 33 feet, below the vent rim — is similar to what we experienced with the Kamoamoa fissure eruption in 2011.
“When this happened, we were not able to tell where lava would emerge, and it could impact safe visitation anywhere along the East Rift Zone,” park officials said.
Although there is no immediate indication that this scenario is happening, park officials are issuing the closures as a precaution and will reevaluate based on any new data from USGS.
No lava spilled over the vent rim and onto the floor of Halemaumau Crater over the weekend.
