Earthquake Then Volcano, There is No Relief For the Hawaii Residents

Hundreds of people have evacuated from Leilani Estates, a community of about 1,700 people, and Lanipuna Gardens.

A massive quake measuring 6.9 on the Richter scale jolted Hawaii residents were evacuating from their homes following a volcanic eruption that has not showed any signs of slowing down, authorities said.

The temblor that struck 16 km southwest of Leilani Estates at 12.32 p.m., on Friday, was one of more than 110 earthquakes that hit the island since the Kilauea volcano, one of the world’s most active, erupted on Wednesday, reports CNN.

US Geological Survey (USGS) seismologist Jana Pursley said there have been 119 earthquakes on the Big Island since Thursday afternoon.

The USGS said Friday’s 6.9 quake was the most powerful on the island since 1975.

The quake has knocked out power to residents who were already dealing with mandatory evacuation orders, molten rock and high levels of sulphur dioxide in the air.

The situation wasn’t getting any better, Civil Defence Administrator Talmadge Magno told reporters on Friday afternoon.

“Activity continues. It doesn’t look like it is slowing down,” CNN quoted Magno as saying.

He said five volcanic vents have opened and indicated that at least one house and another structure were destroyed by lava.

It is highly unusual to see the vents so far from Kilauea volcano, he said.

Hundreds of people have evacuated from Leilani Estates, a community of about 1,700 people, and Lanipuna Gardens.

Harry Kim, Mayor of Hawaii County, said the government will support residents, including those who want to go back to their homes to pick up some belongings.

“We have to work with them as to how we are going to minimise (the inconveniences) as best as possible,” he said.

Kim said people who want to check on their homes would be allowed into the neighbourhoods.

Cracks in Kilauea volcano’s rift zone — an area of fissures miles away from the summit — erupted on Thursday and early Friday, spurting lava near the island’s eastern edge.

Video posted on social media showed lava spewing several feet into the air from a new crack in a Leilani Estates street.

Aerial videos showed lava searing a long orange and smoky line through a wooded area.

Hawaii Eruption Could Last Years, Destroy New Areas: Geologists

A 1,300-foot-wide (400-meter) lava river now flows to the ocean from this "source cone" through an elevated channel about 52 to 72 feet (16 to 22 meters) above ground

The eruption of Hawaii’s Kilauea volcano could last for months or years and threaten new communities on the Big Island, according to a report by U.S. government geologists.

A main risk is a possible change in the direction of a lava flow that would destroy more residential areas after at least 712 homes were torched and thousands of residents forced to evacuate since Kilauea began erupting on May 3, the report by the Hawaiian Volcano Observatory said.

A higher volume of molten rock is flowing underground from Kilauea’s summit lava reservoir than in previous eruptions, with supply to a single giant crack — fissure 8 — showing no sign of waning, according to the study published last week.

“If the ongoing eruption maintains its current style of activity at a high eruption rate, then it may take months to a year or two to wind down,” said the report designed to help authorities on the Big Island deal with potential risks from the volcano.

Lava is bursting from same area about 25 miles (40 km) down Kilauea’s eastern side as it did in eruptions of 1840, 1955 and 1960, the report said. The longest of those eruptions was in 1955. It lasted 88 days, separated by pauses in activity.

The current eruption could become the longest in the volcano’s recorded history, it added.

Geologists believe previous eruptions may have stopped as underground lava pressure dropped due to multiple fissures opening up in this Lower East Rift Zone, the report said.

The current eruption has coalesced around a single fissure, allowing lava pressure to remain high.

A 1,300-foot-wide (400-meter) lava river now flows to the ocean from this “source cone” through an elevated channel about 52 to 72 feet (16 to 22 meters) above ground.

“The main hazard from the source cone and the channel system is a failure of the cone or channel walls, or blockage of the channel where it divides in narrower braids. Either could divert most, if not all, of the lava to a new course depending on where the breach occurs,” the report said.

The report said it only considered risks from a change in lava flow direction to communities to the north of the channel as residents there have not been evacuated, whereas residents to the south have already left their homes. (VOA)
