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.
It turns out that studying lava flows at the bottom of the ocean uses many of the same methods as studying lava flows on other planets, writes Lamont’s Elise Rumpf.
In their quest to unravel the physical and chemical processes controlling volcanic eruptions, Einat Lev and colleagues headed to South America and the volcanoes of Chile.
On every continent and ocean, Earth Institute field researchers are studying the dynamics of climate, geology, natural hazards and ecology, and their practical applications to modern problems. Below, a list of expeditions in rough chronological order. Work in and around New York City and the U.S. Northeast is listed separately toward bottom. Unless otherwise stated, projects originate with… read more
Elise Rumpf’s lava flow simulations are yielding new details about the velocity of lava over different surfaces. They may also hold clues about the surfaces of other planets.
