The enormous amount of volcanic material in the atmosphere would subsequently rain down toxic ash; across the entire US, but principally in the Northwest. The ash would also kill plants, animals, crush buildings with its weight, block freeways, and ruin the country’s farmland for a generation.

Why was Krakatoa so loud?

Originally Verbeek thought that Krakatoa was so fierce because sea water flooded into the volcano, reacting with molten lava; the build-up of pressure from the resulting steam would have led to an enormous blast. Small earthquakes indicate that the volcano is becoming unstable.

What created Krakatoa?

Krakatoa lies along the convergence of the Indian-Australian and Eurasian tectonic plates, a zone of high volcanic and seismic activity. Sometime within the past million years, the volcano built a cone-shaped mountain composed of flows of volcanic rock alternating with layers of cinder and ash.
