Earthquake lights seen Tagish Lake, in the Yukon Territory, in 1972. Large orbs are visible in the foreground, while smaller ones (highlighted by arrows) are seen higher up.

Why Do Lights Sometimes Appear in the Sky During An Earthquake?

Scientists have a new hypothesis to explain the mysterious phenomenon—one that could allow the lights to serve as warning for an impeding quake

A magnitude 7.6 earthquake struck Costa Rica on September 5, 2012, producing a strong shaking through much of the country.

Scientists Successfully Forecasted the Size and Location of an Earthquake

Well before Costa Rica shook in a magnitude 7.6 quake in September 2012, geoscientists forecasted that the region was due for a magnitude 7.7 to 7.8 quake

The Northern Hemisphere's mid-latitudes have experienced many heat waves in recent years, such as one that fueled Rocky Mountain wildfires in summer 2012. Warmer-than-normal temperatures appear red in this NASA image of North America on June 28, 2012.

Summer Heat Waves May Be Linked To Sea Ice Loss

As ice melts, the jet stream gets stuck in the north, causing warm weather to linger in the south--but the reason why this occurs remains unknown

Scientists had to use a remotely operated vehicle to retrieve temperature sensors from a borehole drilled into the Japan Trench, 6,900 meters below the surface of the Pacific Ocean.
