Rivers of lava threaten thousands of homes in Philippines

Rivers of lava threaten thousands of homes in PhilippinesGlowing red lava rolled down the slopes of a Philippine volcano on Tuesday morning as authorities maintained a warning of a possible hazardous eruption.  The lava was quietly flowing in some places but at times Mount Mayon was erupting like a fountain, the Philippine Institute of Volcanology and Seismology said. Lava had advanced up to 2km (1.24 miles) from the crater, and ash reached up to 2km and fell on nearby communities.  Nearly 15,000 people have fled the danger zone within 6 to 7km of Mayon, and the institute strongly advised people not to re-enter the area.  Several small pyroclastic flows were generated by fragments in the lava streams and not by an explosion from the crater vent, like occurred with Mount Pinatubo, said Renato Solidum, who heads the volcano institute. Pyroclastic flows are superheated gas and volcanic debris that can race down slopes and incinerate everything in their path, and are feared in a major eruption.  Lava cascades down the slopes of Mayon volcano, about 210 miles south-east of Manila, Philippines Credit: AP "The pyroclastic flows, there were several, were not generated by an explosion from the crater with lava, molten rocks and steam, shooting up the volcano then rolling down," Solidum said. "These were generated by lava fragments breaking off from the lava flow in the upper slopes."  He also said Mayon has not seen enough volcanic earthquakes of the type that would prompt scientists to raise the alert level to four, which would indicate an explosive eruption may be imminent. Emergency response officials previously said they may have to undertake forced evacuations if the alert is raised to four.  Thousands have fled their homes Credit: AFP After steam explosions Saturday and lava rising in the crater on Sunday, the alert was raised to three on a scale of five, indicating a hazardous eruption is possible "within weeks or even days."  Dark pyroclastic ash rises into the sky Credit: APTN Mayon lies in coconut-growing Albay province about 340km southeast of Manila. With its near-perfect cone, Mayon is popular with climbers and tourists but has erupted about 50 times in the last 500 years, sometimes violently.  In 2013, an ash eruption killed five climbers who had ventured near the summit despite warnings. Mayon's first recorded eruption was in 1616 and the most destructive in 1814 killed 1,200 people and buried the town of Cagsawa in volcanic mud.  The Philippines lies in the so-called Ring of Fire, a line of seismic faults surrounding the Pacific Ocean where earthquakes and volcanic activity are common.  In 1991, Mount Pinatubo in the northern Philippines exploded in one of the biggest volcanic eruptions of the 20th century, killing about 800 people.

Philippine province declares 'calamity' as volcano lava spreads

Philippine province declares 'calamity' as volcano lava spreadsA central Philippine province declared a state of calamity on Tuesday as a volcano spewed lava that reached the limits of a six-km radius no-go zone and spread ash on nearby farming villages. Mount Mayon, a volcano in Albay province in the coconut-growing central Bicol region, has been erupting since Saturday and the number of people fleeing their homes had more than doubled on Tuesday to about 25,000, said Albay Governor Al Francis Bichara. The National Disaster Risk Reduction and Management Council gave a smaller estimate, saying there were close to 22,000 evacuees.

12,000 flee as lava oozes from Philippine volcano

12,000 flee as lava oozes from Philippine volcanoThousands fled from their homes as lava oozed out of a rumbling Philippine volcano on Monday in what volcanologists described as a “quiet eruption”, warning it could lead to a hazardous explosion within days. Lava was slowly flowing out of the Mayon volcano’s crater along with a spectacular 1,000-metre (3,280-foot) ash plume rising into the sky, the nation’s volcanology institute said. It may escalate into a hazardous eruption,” Paul Alanis, science research specialist at the Philippine Institute of Volcanology and Seismology (Phivolcs), told AFP.

NASA finds signs of ancient 'Niagara Falls' of lava on Mars

NASA finds signs of ancient 'Niagara Falls' of lava on MarsSure, NASA has found signs of ancient water on Mars multiple times over the years, but now it's time to talk about something that's significantly more badass: molten Martian lava.  NASA's Mars Reconnaissance Orbiter (MRO) has taken photos of a part of the red planet that once played host to huge multi-tiered falls of lava that cascaded into a crater.  SEE ALSO: NASA's Curiosity rover has a pet rock on Mars The images even show off the (now dried) circular flow of lava at the base of the falls, where the molten rock fanned outward on the crater's floor, NASA said. "The lava flows and falls are distinct as they are rougher than the original features that are smooth and knobby," NASA said in a statement, referring to the features as the "Niagara Falls of Mars."  A 3D view of the lava flow.Image: NASA/JPL-Caltech/Univ. of Arizona"In a close-up image the rough-textured lava flow to the north has breached the crater wall at a narrow point, where it then cascades downwards, fanning out and draping the steeper slopes of the wall in the process."  This isn't the first evidence of lava on Mars. Researchers have also theorized that there were once channels of lava on Mars, and even lava tubes on the red planet, shaping its geology. The MRO has taken thousands of pictures of Mars over the years, revealing features on the surface of the red planet as never before. The orbiter even caught sight of other robots exploring the world below. Image: NASA/JPL-Caltech/Univ. of ArizonaNASA and other space agencies are particularly interested in studying Mars because it might hold their best chance of finding signs of past life in our solar system outside of Earth.   By studying Mars' past, we may be able to learn a little bit more about our own place in the cosmic neighborhood.

Mount Etna lava show lights up Sicilian sky

Mount Etna lava show lights up Sicilian skyBright lava lit up the night sky on the Italian island of Sicily on Monday as Mount Etna erupted for the first time this year. The volcano, one of the most active in the world, has been largely dormant for the last two years, but it sprung to life with bright orange lava spewing out high over the Mediterranean Island, eventually easing off by Tuesday morning. Catania airport, situated within 31 miles of the volcano, remained open, but authorities were tracking the movements of the ash cloud.
