Guatemala? Think of magma like a bottle of champagne. People around Fuego are largely being killed by pyroclastic flows. The contrast offers a reminder that the ways in which volcanoes become dangerous can be as varied as the places and communities where they rumble to life. Presumably, whats happening this time is its been a little more explosive than typical, so these pyroclastic flows are making their way farther down the volcano. Damage came fast and forcefully in a chaotic mixture of rock, gas and ash known as a pyroclastic flow creating scenes of destruction bearing little resemblance to the images of creeping lava that have emerged from Kilauea. Eruptions in the Americas tend to produce enormous amounts of ash, dust, rubble and angular blocks, and the volcanoes often have high, steep cones. Magmas in Hawaii might have water making up only half of a percent by weight.

Rain and storms can mobilize loose rubble on these steep slopes and create cold debris flows. What differences caused Fuego to erupt so violently compared to Kilauea? Unlike Hawaiian volcanoes, eruptions in the Americas tend to produce dense clouds of ash, dust, rubble, and angular blocks that rumble down high, steep slopes. Geophysicists have gotten very good at predicting eruptions at Kilauea in Hawaii and Mount. One promising theory is that water gets sucked under the main flow like hydroplaning on your tires. They are much more explosive partly because magmas they erupt have more water dissolved in them up to 10 times as much as in Hawaiian volcanoes. But those maps were not widely distributed.
