Why do volcanoes turn green?

Scientists initially noticed that ocean water around the volcano was turning green by looking at NASA’s satellite photos of the eruption. The green color turned out to be chlorophyll from the algae bloom.

What is Yellowstone’s beating heart?

How big was the shield volcano when it erupted?

The steady outpouring of lava formed a lake of molten rock that became perched atop a small shield volcano. By June 1991, the shield was about 60 meters tall and 1,600 meters in diameter, and lava from the eruption had covered 75 square kilometers of forest and grassland, added 120 hectares of new land to the island, and destroyed 179 homes.

How much of the earth’s surface is volcanic?

How much of the Earth is volcanic? More than 80 percent of the Earth’s surface–above and below sea level–is of volcanic origin. Gaseous emissions from volcanic vents over hundreds of millions of years formed the Earth’s earliest oceans and atmosphere, which supplied the ingredients vital to evolve and sustain life.
