  • Volcanoes are Fed by ‘Mush’ Reservoirs, Says New Study

    In order to erupt, volcanoes need a source of magma — melted, liquid rock — containing relatively few solid crystals. Traditionally, this magma was thought to be formed and stored in a magma chamber. Recent studies of magma chemistry have challenged this view, leading to the suggestion of the 'mush' reservoir model, where smaller pools of magma sit in the small gaps between solid crystals. However, the mush reservoir model could not explain how magmas containing relatively few crystals arise and are delivered to volcanoes in order for them to erupt at the surface. Now, with sophisticated modeling of mush...
  • Strange waves rippled around the world, and nobody knows why

    On the morning of November 11, just before 9:30 UT, a mysterious rumble rolled around the world. The seismic waves began roughly 15 miles off the shores of Mayotte, a French island sandwiched between Africa and the northern tip of Madagascar. The waves buzzed across Africa, ringing sensors in Zambia, Kenya, and Ethiopia. They traversed vast oceans, humming across Chile, New Zealand, Canada, and even Hawaii nearly 11,000 miles away. These waves didn't just zip by; they rang for more than 20 minutes. And yet, it seems, no human felt them. Only one person noticed the odd signal on the...
  • Why 536 was ‘the worst year to be alive’

    Ask medieval historian Michael McCormick what year was the worst to be alive, and he's got an answer: "536." Not 1349, when the Black Death wiped out half of Europe. Not 1918, when the flu killed 50 million to 100 million people, mostly young adults. But 536. In Europe, "It was the beginning of one of the worst periods to be alive, if not the worst year," says McCormick, a historian and archaeologist who chairs the Harvard University Initiative for the Science of the Human Past.

    Olympia, the Sanctuary of Zeus and venue of the Olympic Games in Ancient Greece, was probably destroyed by tsunamis that reached far inland, and not as previously believed, by earthquakes and river flooding... Paläotsunamis that have taken place over the last 11,000 years along the coasts of the eastern Mediterranean. The Olympic-tsunami hypothesis has been put forward due to sediments found in the vicinity of Olympia, which were buried under an 8 metres thick layer of sand and other debris, and only rediscovered around 250 years ago. "The composition and thickness of the sediments we have found, do not fit...
  • USGS: Yellowstone Super Volcano Threat Set To ‘HIGH’ (No Actual Change To Volcano)

    The United States Geological Survey has increased the Yellowstone supervolcano threat to “high.” This is the first time that the USGS has updated its volcano threat assessments list since 2006. The USGS said that 11 of the 18 volcanoes they have classified as a “high threat” or a “very high threat” are located in Washington, Oregon, or California, “where explosive and often snow- and ice-covered edifices can project hazards long distances to densely populated and highly developed areas.” According to the Epoch Times, the danger list is topped by Kilauea in Hawaii, which has been erupting continuously in 2018. Mount...
  • The 18 Most Dangerous Volcanoes in the United States

    Gizmodo ^ | George Dvorsky
    The U.S. Geological Survey has updated its National Volcanic Threat Assessment, ranking the most dangerous active volcanoes in the United States. To the surprise of no one, Hawaii’s Mount Kilauea is ranked at the top of the list, but other potentially dangerous volcanoes—including some lurking below the public’s radar—are just as worthy of concern. The five most dangerous volcanoes in the United States, both in terms of their likelihood of exploding and their potential threat to human life and property, are Hawaii’s Mount Kilauea, Washington’s Mount St. Helens, Mount Rainier, Alaska’s Redoubt Volcano, and California’s Mount Shasta. Such is the...
  • Mount Vesuvius caused victims' heads to explode, blood to boil: study

    Talk about a headache. When Mount Vesuvius erupted, the explosion caused such extreme heat that victims' skulls exploded, their blood boiled and their muscles, flesh and brains were replaced with ash, according to a new study. "New investigations on the victims' skeletons unearthed from the ash deposit filling 12 waterfront chambers have now revealed widespread preservation of atypical red and black mineral residues encrusting the bones, which also impregnate the ash filling the intracranial cavity and the ash-bed encasing the skeletons," the study's abstract reads.

    In the early 1960s, archaeologist James Mellaart uncovered a mural at Çatalhöyük, the world's largest and best-preserved Neolithic site, which he interpreted to represent a volcanic eruption. Fifty years later, scientific tests done on pumice at the nearby volcano Hasan Dag confirm that there was, in fact, an eruption between 9,500 and 8,400 years ago -- a timespan including the era that the mural was likely painted. ...In an Archaeology Odyssey article, Michael Balter, author of The Goddess and the Bull, wrote: "One painting, he [Mellart] thought, seemed to represent a town plan of the Neolithic village, with an erupting...

    Hurricane Hector became a Category 4 storm for a few hours early Sunday but then dipped back to Category 3, still a dangerous force, as it headed across the Pacific, threatening to hit Hawaii's Big Island and possibly its active volcano, officials said early Sunday. Hector's winds dropped to 125 mph from 130 mph, the diving line between Categories 3 and 4, early Sunday as it moved westward at 12 mph Sunday, the National Hurricane Center said in an advisory.

    The National Guard in Hawaii is warning of new, immediate dangers to people living near the Kilauea volcano some two-and-a-half months after the eruption started. At the same time lava flow is changing the outline of the island itself and creating hundreds of acres of new land where the ocean used to be. The island has grown by nearly 700 acres, the equivalent of more than 500 football fields, reports CBS News' Carter Evans.

    The ongoing eruption of Hawaii's Kilauea Volcano and continued lava flows into the sea has created a tiny new landmass off the Big Island, officials revealed Friday. The U.S. Geological Survey said the tiny island formed off the northernmost part of the ocean entry from Fissure 8, and was oozing lava similar to that of the larger lava flow along the coast. In photos posted by the agency, the "island" is just a few meters off shore, and about 20 to 30 feet in diameter. "It's most likely part of the fissure 8 flow that's entering the ocean—and possibly a...
  • At Least 4 People Die After 5.3 Magnitude Earthquake Strikes Osaka: Japanese Gov’t

    A strong earthquake hit the Japanese city of Osaka during morning rush hour Monday, killing at least four people and injuring 214, Japan’s government says. The 5.3 magnitude quake shook Osaka, on Japan’s main Honshu Island, around 8 a.m. Monday local time (7 p.m. Sunday ET) according to the US Geological Survey (USGS). The Japan Meteorology Agency put the magnitude at 5.9. It rated the quake at “6 Lower” on its JMA Seismic Intensity scale, meaning the shaking would have been severe enough to make it difficult to remain standing. And Meantime, on the other side of the Pacific, a...

    Lava from Hawaii's Kilauea volcano has created nearly a mile of new land. US Geological Survey officials said the flow, which has filled Kapoho Bay, is still active and there is no way of knowing when the eruption will end or if more lava-spewing vents will open. The fast-moving lava poured into low-lying coastal Hawaii neighbourhoods in the space of just two days this week, destroying hundreds of homes. The eruptions began early last month and is believed to be the volcano's most destructive episode in modern history.

    A seemingly odd fireman is fighting fires in Guatemala—Israel. Even before Guatemala’s Vulcan del Fuego resumed its restless sleep Sunday evening, Israel issued emergency aid from its embassy including $10,000 for medical purchases. The pyroclastic flow that erupted from Vulcan del Fuego slammed into the village of El Rodeo at the base of the volcano, killing at least 69. Due to the close proximity of the volcano to Guatemala City, some 1.7 million people have been affected. In response to the tragedy, President Jimmy Morales declared three days of national mourning.

  • Ancient ashes reveal details of huge volcano

    Archaeologists have discovered ashes from one of the biggest ever volcanic eruptions in recorded history. Excavations in Turkey’s ancient city of Smyrna, now located in Izmir, have revealed details from a Minoan eruption that took place some 3,600 years ago. Smyrna was established about 5,000 years ago by the Greek tribe of Aeolians and later inhabited by Ionians. It was mostly abandoned after it was captured by the Anatolian kingdom of Lydia in the 6th century B.C. Archaeologists say the ashes will tell them a lot about the history. “Now that we have identified those ashes with a more extensive...

    Rescuers struggled to reach rural residents cut off by a volcanic eruption that killed at 25 people near Guatemala's capital, and authorities feared the death toll could rise with an undetermined number of people unaccounted for. The Volcan de Fuego, Spanish for "volcano of fire," exploded in a hail of ash and molten rock shortly before noon Sunday, blanketing nearby villages in heavy ash. Then it began sending lava flows down the mountain's flank and across homes and roads around 4 p.m. local time Eddy Sanchez, director of the country's seismology and volcanology institute, said the flows reached temperatures of...

    At least six people were killed and another 20 injured on Sunday when Guatemala's Fuego volcano erupted violently, spewing a stream of red hot lava and belching a thick plume of black smoke and ash that rained onto the capital and other regions. "It's a river of lava that overflowed its banks and affected the Rodeo village. There are injured, burned and dead people," Sergio Cabanas, the general secretary of Guatemala's Conred disaster agency, said on radio. "We are evacuating and rescuing people and have reports of 20 wounded, six dead and disappeared," said Cabanas. An ash covered woman said...
