Hawaii’s Kilauea volcano might be “getting ready for an explosion that could scatter ash and debris for miles,” according to Reuters. “More explosive activity generating larger ash clouds remains possible and can occur with no warning,” a U.S. Geological Survey warning on Sunday night read. The agency estimates that a 20,000-foot plume of ash could erupt and spread debris for “over 12 miles.”
Lava from a huge new fissure tore through farmland towards a coastal dirt road that is one of the last exit routes for some 2,000 residents in the southeast area of Hawaii’s Big Island.
More lava-belching cracks are expected to open among homes and countryside some 25 miles (40 km) east of Kilauea’s smoking summit, possibly blocking one of the last exit routes, Highway 132.
Fountains of magma spouted “lava bombs” more than 100 feet (30 meters) into the air as the molten rock traveled east-southeast towards the coastal road - Highway 137 - the Hawaiian Volcano Observatory said.
“There’s a lot of worst-case scenarios and roads getting blocked is one of them,” said Hickman, standing on Highway 137, in the potential path of the lava flow, some two miles (3 km) away.
ERUPTIONS COULD LAST WEEKSDozens of homes have been destroyed since eruptions began 10 days ago and officials have ordered the evacuations of nearly 2,000 residents in the lower Puna district of the Big Island, home to around 187,000 people.
The American Red Cross said 500 people sought refuge in its shelters on Sunday night because of worsening volcanic activity.
Two more fissures opened in the past 24 hours, bringing the total to 19.
“It’s optimistic to think that this is the last fissure we’re going to see,” said Hawaiian Volcano Observatory Deputy Scientist-In-Charge Steve Brantley. A similar seismic event in 1955 lasted 88 days, he said.
Unnerved by near-constant small earthquakes and emissions of toxic sulfur dioxide gas, Rob Guzman and his husband Bob Kirk left their home in Kalapana Seaview Estates while they still could.
The Hawaii Fire Department issued a “condition red” alert on Monday because fissures in the southeast area of the Lanipuna Gardens area were issuing high levels of sulfur dioxide.
“Condition RED means immediate danger to health so take action to limit further exposure. Severe conditions may exist such as choking and inability to breathe,” the department said in the alert.
While residents deal with noxious gas and lava on the ground, the U.S. Geological Survey is concerned that pent-up steam could cause a violent explosive eruption at the volcano crater, launching a 20,000-foot (6,100-meter) plume that could spread debris over 12 miles (19 km).
Scientists had expected such explosions by the middle of this month as Kilauea’s lava lake fell below the water table. The possibility exists, however, that water may not be entering the crater, as feared, and gas and steam may be safely venting, scientists said.
“So far those explosions have not occurred and I think the key here is that the vent system is an open one, therefore pressure is not being built or developed down at the top of the lava column,” Brantley told a conference call.
