Hawaii’s Kilauea volcano could have ‘explosive’ eruption, authorities warn
GEOLOGISTS have warned of a building threat, bubbling away in the heart of Hawaii’s Kilauea volcano, amid fears acid rain could contaminate the island’s water supply.
HAWAII’S Kilauea volcano could erupt explosively sending boulders and ash hurtling hundreds of metres into the air, geologists have warned.
The United States Geological Survey issued a warning on Wednesday that explained if the lava lake within the “Overlook crater” drops to the level of groundwater beneath the Kilauea Caldera, it could cause a steam-driven explosion.
“Debris expelled during such explosions could impact the area surrounding HalemaÊ»umaÊ»u and the Kilauea summit. Primary hazards of concern should this activity occur are ballistic projectiles and ash fall,” the agency said.
There is also risk of acid rain, which can contaminate the island’s water supply.
Steam-driven explosions typically provide little warning and can be violent.
In addition to throwing out ballistic projectiles, volcanic gases such as sulfur dioxide can be emitted.
The agency has warned that such emissions can be hazardous.
Officials continue to monitor the levels of harmful gases. They’ve also warned that dangerous levels of sulfur dioxide gas could combine with moisture and dust to form volcanic smog (vog). The vog can carry drops of sulfuric acid which can cause respiratory problems, and damage the lungs.
Travellers with existing heart conditions, respiratory ailments and those who are pregnant, are advised to check with their physicians before visiting the Big Island.
At this stage flights haven’t been affected, but travellers are urged to check their airline regularly for announcements.
Kilauea is one of the world’s most active volcanoes.
Since last week, vents have popped open across the island releasing lava, gas and steam inside residential neighbourhoods.
There’s no indication when the activity will cease, or how far the lava will spread. A total of 36 structures have been destroyed and 26 of them have been confirmed as homes.
Residents of the Leilani Estates subdivision were evacuated last week after the first fissure opened on a street.
Authorities ordered 2000 residents within the Big Island’s mostly rural district of Puna to leave the area. But some ignored the order to watch over their property.
However, police made an urgent plea to the remaining residents on Tuesday, after two new vents opened up.
Hawaii County issued a mobile phone alert ordering stragglers within the Lanipuna Gardens area to get out immediately.
