This potential for an explosive eruption has prompted a total closure of Hawaii Volcanoes National Park All of this is happening because now the lava lake level will be below the water table, so water can directly create more steam in the conduit and interact with the lava. Would be pressure building after rock falls choke in the conduit that feed the lava lake, along with some mixing of lava and water to increase the explosiveness. (see below), so the chances of potential steam-driven explosionsĪt the summit might be increasing.
This is all happening at the same time as the summit lava lake at Halema'uma'u is continuing to drop

UPDATE 12:15 pm EDT May 10: Here are some more details on the current assessment of the situation by the scientists at the Hawaii Volcano Observatory:Īnother amazing picture (9th May) provided by Bruce Omori about the fissure eruption at the East Rift Zone, Big Island, Hawaii. So far, this eruption has covered over 115 acres of land in and around Leilani Estates and destroyed at least 35 structures (mainly homes), displacing thousands of residents. Earthquakes continues under the Puna area where the fissures opened and there is some indication that magma could be moving further down the East Rift zone, so the potential for eruptions to the northeast of Leilani Estates might be increasing. However, as with most volcanoes, the real action to watch is happening underground. The mixture of water and sulfur dioxide makes acid, which can then irritate eyes, nose, mouth and lungs (at best) and cause extreme respiratory distress and death (at worst). So, right now, that is the biggest hazard for people on the east side of the big island: the threat of volcanic fog, or vog. The fissures that opened in Leilani Estates (see above) haven't erupted much new lava, but the are still emitting copious amounts of volcanic gases like sulfur dioxide.
The eruptions at Kilauea took a bit of a break over the last day - at least at the surface. A USGS scientist measures the temperature of gases emitted from a fissure at Leilani Estates on May 9, 2018.
