Tsunamis following the explosive Krakatoa eruption occurred when pyroclastic flows entered the sea, not because the caldera collapsed, Nomikou said.

The enormous tsunami thought to have destroyed the legendary lost city of Atlantis could have been caused by lava, a new theory suggests. Experts believe material from the volcanic eruption on Sant… ...

Pressures within pyroclastic flows may be as much as three times as great as observations had suggested.

The eruption sent devastating tsunamis across the eastern Mediterranean that smashed into the Minoans on Crete, at the time one of the world’s most advanced civilisations.

For the first time, scientists have discovered the driving force behind the deadly currents of volcanic particles and gas called pyroclastic flows.

Pyroclastic flow is full of rocks, ash and hot gas. It blasts across the ground at speeds over 50 mph and is incredibly hot — sometimes over 1,000 degrees Fahrenheit.

The explosive pyroclastic flows caused by the Fuego volcano are not the same type of flows coming from Hawaii's Kilauea.
