Earth’s Crust Is Tearing Apart off the Pacific Northwest—and That’s Not Necessarily Bad News
Using seismic reflection imaging—essentially an ultrasound of the Earth’s subsurface—and detailed earthquake records, researchers captured a subduction zone in the process of tearing itself apart.

Study of Extreme Indian Rainfall Upends Conventional Wisdom
While El Niño often brings drought conditions to India, a new paper shows that it also increases the likelihood of devastating downpours in some of the country’s most heavily populated regions.
By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
