Kilauea volcano eruption is one of the biggest in recent Hawaii history, enough to fill 100,000 pools

That’s a lotta lava. Since the eruption of the Kilauea volcano May 3 on the Big Island, it’s belched out about 250 million cubic meters of lava, making it one of the largest eruptions in decades in Hawaii. “It’s nothing like what we’ve witnessed in recent history,” Wendy Stovall said.

Volcano music could help scientists monitor eruptions

A volcano in Ecuador with a deep cylindrical crater might be the largest musical instrument on Earth, producing unique sounds scientists could use to monitor its activity. New infrasound recordings of Cotopaxi volcano in central Ecuador show that after a sequence of eruptions in 2015, the volcano’s crater changed shape. The deep narrow crater forced air to reverberate against the crater walls when the volcano rumbled.

Is Hawaii's Kilauea volcano shooting green gems into the air?

Is Hawaii's Kilauea volcano shooting green gems into the air?Embedded in the lava still spewing some 130 feet into the air from Hawaii’s Kilauea volcano are green crystals.  Called olivine, these minerals can turn Hawaiian beaches green, and it appears some of the green gems are raining down upon homes near the eruption or popping up near lava flows. SEE ALSO: Lava transforms a Hawaiian bay into a blackened peninsula U.S. Geological Survey (USGS) scientist Wendy Stovall, who was out studying Kilauea last week, confirmed that recent lava samples do contain olivine, though she didn’t happen upon any separated green crystals herself.  Other folks in the area, however, appear to be collecting the tiny green gems as they see them: Friends of mine live in Hawaii, right next to the area impacted by the most recent lava flows. In the midst of the destruction nearby & stress of the unknown, they woke up to this – tiny pieces of olivine all over the ground. It is literally raining gems.

Sometimes the crystals can be simply weathered out from old lava rocks. Or, in the case of green-tinged Hawaiian beaches, lava can erupt through ocean water in steamy, explosive events, breaking the lava into smaller pieces and fast-tracking the separation process, said Stovall.  Small green olivine crystals on a Big Island beach.Image: Stanley MertzmanBut in the case of this olivine presumably falling down on property near the eruption, the crystals “just kind of fall out” as lava is spewed into the air, said Stovall. “The olivine crystals folks are finding on the ground scattered about are from violently ejected basalt [a type of lava] blobs wherein the embedded, earlier-formed olivine crystals are freed from their surrounding pahoehoe [syrupy lava] basalt liquid,” Stanley Mertzman, a volcanologist at Franklin and Marshall College, said over email. Both violent ejections on land and from lava flowing into the ocean can “produce freed individual olivine crystals that people can pick up any time,” said Mertzman. Olivine crystals embedded in a Hawaiian lava rock.Image: Stanley MertzmanThe crystals may be flying through the air from exploded bits of lava, but it’s unlikely they’re also coming from the volcano’s summit, where there’s been a large plume of steam and ash erupting from the crater — and at times rare, explosive eruptions.  “One thing I can say is that olivine is not raining out of the plume,” Michael Poland, a USGS volcanologist, said over email. Poland added that olivine is common on the ground regardless, because roads in Hawaii are made up of ground up olivine-rich lava rock.

They’ve been formed deep underground long ago, brewing in the molten rock.  “It really is one of the first things to form,” said Stovall.  And olivine might not be the only crystal falling down inside the nearby neighborhood. “It’s possible that other crystals are being found,” said Stovall, adding that a USGS rock specialist said olivine is difficult to tell apart from another common crystal, called clinopyroxene. It’s also quite possible nearby islanders will continue to find semi-translucent crystals on the ground. The eruption, over a month old now, shows no signs of relenting, and could very well last months — or longer. WATCH: These trees have lived for 2,500 years. Now they’re suddenly dying

Minor explosion at Hawaii volcano spews more ash into the air

Minor explosion at Hawaii volcano spews more ash into the air(Reuters) – A small explosion at the summit of Hawaii’s Kilauea Volcano shot more ash high into the atmosphere, putting communities in the southern part of the Big Island at risk, the U.S. Geological Survey (USGS) said. The volcano, which has been erupting since early May, has sent occasional columns of ash and volcanic gas into the atmosphere at between 10,000 (3,050 meters) and 30,000 feet (9,145 meters) above sea level, it said. On Sunday, another explosion spewed ash from the volcano, creating a driving hazard for roads on parts of the Big Island.
