Hawaii's Kilauea volcano could keep erupting for months. Here's why.

Hawaii's Kilauea volcano could keep erupting for months. Here's why.Hawaii’s young, lively Kilauea volcano shows no signs of slowing down.  On May 4, the first lava-swollen fissure opened up in the Leilani Estates neighborhood on the eastern flank of Kilauea. Soon after, 16 more fissures opened in the area.  Meanwhile, near the volcano’s gently-sloping summit, a lava lake recently brimming with steaming molten rock has since drained, an event government scientists now say could trigger a rare explosive blast from the ominous pit, shooting boulders some 10 tons (or more) into the area. SEE ALSO: An astronaut saw Hawaii’s Kilauea volcano erupting from space. And he took a picture. But volcanologists, while pretty good at determining when a volcano might erupt, don’t have the same ability to predict when an eruption might come to an end. “It’s difficult to say with any certainty,” Michael Poland, the Scientist-in-Charge at the U.S. Geological Survey’s Yellowstone Volcano Observatory, said in an interview. “Forecasting the end is surprisingly hard.” An aerial view of fissure 17 in the Leilani Estates neighborhood taken on May 14.Image: usgsBut in the case of Kilauea, there are strong clues that the eruption could continue “for weeks, if not months,” said Poland. When lava comes out of the ground, the USGS carefully collects and analyzes pieces of the cooling molten rock. And since the volcano’s activity increased in early May, the lava’s composition has changed. At first, the lava was the same stuff that’s been spewing out of the volcano for some 60 years, Poland said. Now, a different, “fresh” type of lava is coming out of the ground, meaning that new magma (underground lava) is on the move deep inside the volcano, which could continue to feed the eruption. “That’s a sign it could go on for weeks to months,” said Poland.  At Kilauea, two large, lava-filled vents have emptied, indicating that their lava erupted into the nearby neighborhood and that new sources are continuing to feed the eruption.  The emptied lava vent Pu‘u ‘Ō‘ō, which previously had been erupting for 35 years.Image: USgsThe magma is moving around in chambers located miles underground, so it’s difficult — if not impossible — to measure how much swirling molten rock is down there and how much more might bubble to the surface. “It’s really hard to tell,” Erik Klemetti, a volcanologist at Denison University, said in an interview. “And that’s the key piece behind how long an eruption may go on.” But, scientists can look at past Kilauea eruptions for a good idea. Kilauea, fortunately, happens to be one of the most closely observed volcanoes on Earth. “Kilauea is a relatively unique case because we have such good historical data,” said Klemetti. “We have been monitoring it for quite some time. In fact, scientists opened the Hawaii Volcano Observatory on Kilauea in 1912 and have witnessed a variety of eruptions since then. The 1960 Kilauea eruption lasted a month, and similar to this eruption, lava covered roads, and even flowed through and destroyed the village of Kapoho.  Large ground fractures in Kapoho village, caused by magma moving underground in January 1960Image: usgsAround 90 percent Kilauea’s surface is covered in geologically fresh lava, less than 1,000 years old. This means that the young volcano is still growing into a gently-sloping “shield-like” shape.  The type of eruption we’re seeing today is “very normal for a shield volcano,” said Poland. “But that’s small solace for people that live there.” It’s just unknown how long each eruption might last. “Weeks to months is a pretty good estimate,” said Klemetti. “But it wouldn’t shock me if it lasted longer than that.” “But if it ended soon, it would surprise me more.” WATCH: From Norway to India, these ‘pollution pods’ let you sample the worst and the best air quality of cities around the world

Earthquakes, lava fissures could last for months on Hawaii – USGS

Earthquakes, lava fissures could last for months on Hawaii - USGSBy Karin Stanton PAHOA, Hawaii (Reuters) – More homes on Hawaii’s Big Island were destroyed on Saturday as eruptions linked to the Kilauea volcano increased, spewing lava into residential areas and forcing nearly 2,000 people to evacuate, officials said. The U.S. Geological Survey (USGS) said on Saturday that several new lava fissures had opened in the Leilani Estates subdivision of Puna District, about a dozen miles (19 km) from the volcano. The Hawaiian Volcano Observatory said at midday local time on Saturday that “eruptive activity is increasing and is expected to continue.” Janet Babb, a spokeswoman for the observatory, said by telephone that the eruptions could carry on “for weeks or months.” Babb said the activity since Thursday is beginning to show similarities to another event in the area in 1955 that lasted for 88 days, when far fewer people lived near the volcano.

Months after Parkland shooting, Trump embraces NRA in campaign-like speech

Months after Parkland shooting, Trump embraces NRA in campaign-like speechBy Jeff Mason and Daniel Trotta DALLAS (Reuters) – President Donald Trump urged gun-rights advocates on Friday to support Republican candidates in the November congressional elections, warning that Democrats would try to tighten firearms laws in the wake of a string of mass shootings. Speaking at the annual convention of the National Rifle Association in Dallas, Trump said, “The one thing that stands between Americans and the elimination of our Second Amendment rights has been conservatives in Congress.” He said, “We’ve got to get Republicans elected.” Trump’s Republicans are fighting to maintain their majority control of Congress in November’s midterm elections.
