Scientists probing under the seafloor off Alaska have mapped a geologic structure that they say signals potential for a major tsunami in an area that normally would be considered benign.

On every continent and ocean, Earth Institute field researchers are studying the dynamics of climate, geology, natural hazards, ecology and other subjects with direct applications to the challenges facing humanity.
An all-purpose guide for journalists covering disasters, natural and manmade.
A new pilot program led by the Lamont-Doherty Earth Observatory aims to provide earlier and more accurate warnings of damaging ground-shaking from earthquakes and the imminent arrival of tsunamis.
A new film takes viewers from the eastern highlands of India to the booming lowland metropolis of Dhaka, the capital of Bangladesh–and explores an ever-more detailed picture of catastrophic earthquake threat that scientists are discovering under the region.
On a ledge just inside the lip of Chile’s Quizapu volcanic crater, Philipp Ruprecht was furiously digging a trench. Here at an elevation of 10,000 feet, a 1,000-foot plunge loomed just yards away, and wind was whipping dust off his shovel. But the volcanologist was excited. Ruprecht had just found this spot, topped with undisturbed wedding-cake layers of fine, black material that the crater had vomited from the deep earth some 84 years ago. Samples from the currently inactive site might shed light on its exceedingly violent behavior.
High in the southern Andes, Chile’s Quizapu crater is one of South America’s most fearsome geologic features. In 1846, it was the source of one the continent’s largest historically recorded lava flows. In 1932, it produced one of the largest recorded volcanic blasts. The volcano is currently inactive, but could revive at any time. What is next?
From crowd-sourcing tornado data to teaching Harlem high-school students about climate change and climate justice, IRI scientists will share a number of fascinating projects at the annual meeting of the American Meteorological Society
On Hawaii, lava is a way of life. The whole island is made of the stuff. Eruptions from Kilauea volcano have been adding new land and wiping out old for all of human time, and far before. In recent decades, lava flows have wiped out communities and major roads. The latest eruption, which began in June 2014, now… read more
When the most recent eruption of Hawaii’s Kilauea volcano started last June, Melvin Sugimoto at first did not think much of it. Hawaii, where he has lived all his life, is made entirely of hardened lava, and Kilauea, perhaps the world’s most active volcano, has been adding more off and on for the last 300,000 years. “Lava is… read more
