Hawaii volcano: New land formed as lava flows meet ocean

Hawaii volcano: New land formed as lava flows meet oceanThe footage taken from a helicopter also reveals the interaction between lava and seawater creating a white plume called “laze”. The new land looks stable, but hides a foundation of loose rubble that can collapse into the ocean, according to scientists at the United States Geological Survey. An entire neighbourhood has been wiped off the map in Hawaii as Kilauea continues to spew lava.

New evacuations ordered on Hawaii's Big Island as lava flows from volcano threaten roads, destroy homes

Big Island authorities ordered more mandatory evacuations from the neighborhood where lava eruptions and flows have already destroyed dozens of homes. And now they’re warning that anyone who stays behind could be held liable for rescue costs if they get trapped and call for help.

Hawaii volcano latest: Molten lava flows onto power plant site amid fears over deadly gases

Hawaii volcano latest: Molten lava flows onto power plant site amid fears over deadly gasesMolten lava from Hawaii’s erupting Kilauea volcano crept onto the site of geothermal power plant as workers raced to shut down facilities, amid fears that deadly gases could be released. Crews worked to cap underground wells at the plant, which provides a quarter of Big Island’s power, as the molten rock destroyed a warehouse a few hundred metres away. If lava enters the wells at the Puna Geothermal Venture plant, it could trigger the uncontrollable release of noxious sulphates, officials have warned.

Hawaii's destructive lava flows hit the ocean, making the Big Island bigger

Hawaii's destructive lava flows hit the ocean, making the Big Island biggerThe history of Hawaii is a tale of lava flowing into the sea.  Bounties of fresh lava poured out of the Kilauea volcano’s recently opened fissures this weekend, producing orange molten rivers that flowed downslope to the Pacific Ocean. When they met, the lava chilled into rock while creating plumes of acidic steam.  These lava flows, while devastating for homes in the way of these flows, will gradually add new land to the Big Island, continuing a long geologic history of natural island-building.   “This is the common way in which the island grows laterally,” George Bergantz, a volcanologist at the University of Washington, said in an interview. “It’s lava flow, on top of lava flow, on top of lava flow.” SEE ALSO: Deep beneath the Pacific, another active Hawaiian volcano waits to emerge Not every addition to the Big Island involves an eruption that puts people at risk and engulfs their communities. For decades, Kilauea has experienced continuous lava flows through a vent called PuÊ»u ʻŌʻÅ� in Hawaii Volcanoes National Park, incrementally adding land to the southeast portion of the island.  This continuous flow has added 570 acres of land to Hawaii’s Big Island since 1983, according to the U.S. Geological Survey’s most recent update. Meanwhile, the lava has also blanketed over 40 square miles of rainforest, communities, and historical sites. #NOAA20 satellite captured the light from the lava glowing through the clouds from Hawaii’s #Kilauea’s fissure 20 🌋.

In a separate event, the volcano exhibited rare, explosive activity, sending ash tens of thousands of feet into the sky. In other words, the ash-filled eruptions and massive evacuations are unusual — but lava flows from Kilauea are not. It’s also normal for lava to reach the sea in steamy, even explosive meetings of heat and water. Kilauea’s lava flows head downslope to the Pacific Ocean on May 19.Image: usgsThe Big Island’s new land, however, is far from stable. The young, cooled rock is constantly pounded by waves. And as this new land settles down and sinks, sea water can find its way in through cracks, creating bursts of lava.  “You’re going to be adding land, but it’s incredibly unstable,” Michael Poland, of the USGS’s Yellowstone Volcano Observatory, said in an interview. “Everything about it is unstable.”  Prior to the beginning of Kilauea’s recent eruption activity, lava regularly entered the ocean and built new land.Image: USGSSometimes, this natural land-building can take a sizable step back — specifically, by collapsing.  “Occasionally you’ll get collapses that eat into the landscape,” said Poland. “It’s a construction-deconstruction process,” said Bergantz.

Even if new land extends just 10 or 20 feet offshore, the USGS recommends standing at least 330 yards away, as collapses and toxic plumes aren’t just possible — they’ve killed people ignoring signage.  Eventually, the land will stabilize. This requires one common ingredient: more lava flows.  “If you get enough lava coming in, it’ll start growing itself laterally to form a much more solid and coherent set of lava flow benches [or landforms],” said Bergantz.  For now, considerable amounts of fresh lava continues to spatter, fountain, and pour out of recently opened lava fissures, incrementally adding new — though still unstable — land.  “It’s just remarkable what’s going on there right now,” said Bergantz.
