Pyroclastic flows at Guatemala’s Santa Maria and vigorous explosions at Fuego rank among the most active volcanic pairings on Earth right now
Roughly 50 kilometers separate two of Central America’s most dangerous volcanoes, and both are erupting. At Santa Maria, the ...
Pyroclastic flows are some of the most fearsome hazards posed by erupting volcanoes. These avalanches of superheated ash, gas, and rock are responsible for some of the most famous volcanic disasters ...
MANILA, Philippines — Since showing increased activity earlier this year, Mayon Volcano generated its "largest" pyroclastic density current so far, with an ash plume reaching up to 1,000 meters on ...
Pyroclastic density currents (PDCs) are high-energy, ground-hugging flows of hot gas and fragmented volcanic material that pose one of the greatest lethal volcanic hazards. Their dynamics are governed ...
