A study of ancient eruptions shows modern ice sheets could be vulnerable.

Despite recent media reports, there’s no imminent threat, says Columbia geologist Einat Lev.
Where once scientists could only observe earth from above by using manned aircraft or satellites, today they are expanding, developing and refining their research in a variety of ways thanks to drones.
What do the scientists and researchers around the Earth Institute do? In this second in a series, Einat Lev from the Lamont-Doherty Earth Observatory talks about her work on volcanoes what she’d like people to know about it, and what inspired her to go into the field.

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?
One of the earth’s newest islands exploded into view from the bottom of the southwest Pacific Ocean in January 2015, and scientists sailing around the volcano this spring have created a detailed map of its topography.
Elke Weber, who studies how people make decisions and how they think about climate change, and Terry Plank, who probes deep into the Earth’s interior to study magma and how volcanoes erupt, are among the members elected to the American Academy of Arts and Science this year.
Accounting for Volcanoes Using Tools of Economics
Climate scientists teamed up with an econometrics expert to develop an innovative new method for picking out past volcanic eruptions in temperature reconstructions going back millennia and gauging their impact on the climate.
