Supervolcano Cleared in Neanderthals' Demise

Supervolcano Cleared in Neanderthals' Demise | Dynamic Earth | Scoop.it
Neanderthals disappeared from Europe starting 40,000 years ago, after the region's biggest volcanic blast in the last 200,000 years sent superheated pyroclastic flows of volcanic gas and ash sky-high. But don't blame the volcano, scientists say.

Supercontinent Pangaea Pushed, Not Sucked, Into Place

Supercontinent Pangaea Pushed, Not Sucked, Into Place | Dynamic Earth | Scoop.it
A plume of superheated rock from deep in Earth's crust welled up between the ancient continents, pushing them apart until they collided to form Pangaea, a new study proposes.

A history of supercontinents on planet Earth

A history of supercontinents on planet Earth | Dynamic Earth | Scoop.it
Earth's continents are constantly changing, moving and rearranging themselves over millions of years - affecting Earth's climate and biology. Every few hundred million years, the continents combine to create massive, world-spanning supercontinents.

Volcanic Tsunamis | Volcano World

Volcanic Tsunamis | Volcano World | Dynamic Earth | Scoop.it

A tsunami is a huge sea wave, or also known as a seismic sea-wave. They are very tall and height and have extreme power. A tsunami is formed when there is ground uplift and quickly following a drop. From this, the water column is pushed up above the average sea level. Volcanic tsunamis can result from violent  submarine explosions.

 

They can also be caused by caldera collapses, tectonic movement from volcanic activity,  flank failure into a water source or pyroclastic flow discharge into the sea. As the wave is formed, it moves in a vertical direction and gains great speeds in deeper waters and can reach speeds as fast as 650 mph. In shallow water it can still be as fast as 200mph.

 

They travel over the continental shelf and crash into the land. This power doesn’t decrease when they hit land though, there is an extreme amount of energy when the water travels back towards its source. Approximately 5 percent of tsunamis are formed from volcanoes and approximately  16.9 percent of volcanic fatalities occur from tsunamis. (Tanguy, J.C. 1998)
