In the lab, machine learning improves quake forecasts

The U.S. Geological Survey estimates that about 500,000 detectable earthquakes occur worldwide every year. But accurate forecasts of when quakes will occur have long been out of reach, in large part because of the complexities of fault behavior.

Seismic patterns help forecast eruptions from quiet stratovolcanoes

Earth is home to more than 1,500 potentially eruptive volcanoes on land, each with a unique character and history. Predicting when and how a particular volcano may erupt is notoriously difficult, in large part because each eruption is unique. Recent work tracking pre-eruptive seismic behavior beneath two dozen reawakened volcanoes has revealed a distinctive pattern that seismologists may be able to use to assess when — and how violently — a rumbling volcano could blow its top.

Hurricane hunters fly toward improved storm forecasts

Hurricanes are one of the few natural disasters that strike with some advance notice. Forecasts can be made hours or even days ahead of landfall, giving communities time to prepare and evacuate. Nevertheless, the forecasts are not exact, and improving their accuracy — in terms of timing, location of landfall and wind intensity — poses an ongoing challenge. Two recent studies detailing the latest advances in data collection and assimilation may help improve forecasting as early as this year.

Foretelling next month's tornadoes

Tornadoes are notoriously difficult to forecast, with often deadly results: In 2011, tornadoes in the U.S. killed more than 550 people, a higher death toll than in the past 10 years combined. Now a new study of short-term climate trends offers a new approach to tornado forecasting that may give people in tornado-prone regions as much as a month of forewarning that twisters may soon be descending.
