Hawaii volcano lava reaches geothermal plant area
Honolulu, May 23: Relentless lava flow from Hawaii's Kilauea volcano which had erupted 19 days ago, has now reached the Puna Geothermal Venture property, Hawaii County's civil defence agency said.
The plant produces electricity by bringing steam up from underground wells and funnelling it to a turbine generator, reports CNN.
Officials are trying to prevent possible explosions or the release of toxic fumes by "quenching" most of the wells, Hawaii Emergency Management Agency spokesman Thomas Travis said on Tuesday.
Quenching starts with filling underground wells with cold water. So far, 10 of the 11 wells at the geothermal plant have been quenched, according to agency officials.
Travis said workers might also try to plug the wells, perhaps by filling them with mud and capping them with iron plugs.
Meanwhile, toxic sulphur dioxide gas is still spewing from cracks in the earth's surface after the eruption that took place on May 3 prompting massive evacuations from the adjoining areas of Leilani Estates and the adjacent Lanipuna Gardens located on the Big Island.
A latest eruption took place early Tuesday morning.
Residents "should be prepared to leave the area with little notice due to gas or lava inundation", Hawaii County's civil defence agency said.
Since Kilauea's eruption, rivers of fire have swallowed at least 40 structures, hurled lava through cracks in the earth's surface and devastated livelihoods, reports CNN.
The lava entered the Pacific Ocean on May 19.

Pakistan reports two more polio cases; Total tally now 52
ISLAMABAD: At least two more cases of poliovirus were reported in Pakistan, taking the number of infections to 52 so far this year, a report said on Friday.
“The Regional Reference Laboratory for Polio Eradication at the National Institute of Health has confirmed the detection of two more wild poliovirus type 1 (WPV1) cases in Pakistan," an official statement said.
The fresh infections — a boy and a girl — were reported from the Dera Ismail Khan district of Khyber-Pakhtunkhwa province.
“Genetic sequencing of the samples collected from the children is underway," the statement read. Dera Ismail Khan, one of the seven polio-endemic districts of southern Khyber Pakhtunkhwa province, has reported five polio cases so far this year.
Of the 52 cases in the country this year, 24 are from Balochistan, 13 from Sindh, 13 from Khyber Pakhtunkhwa, and one each from Punjab and Islamabad.
There is no cure for polio. Only multiple doses of the oral polio vaccine and completion of the routine vaccination schedule for all children under the age of five can keep them protected.
