Atmosphere Above Japan Heated Rapidly Before M9 Earthquake

New satellite data shows that the atmosphere above Japan heated rapidly in the days before the March earthquake.

The [researchers] say that before the M9 earthquake, the total electron content of the ionosphere increased dramatically over the epicentre, reaching a maximum three days before the quake struck. At the same time, satellite observations showed a big increase in infrared emissions from above the epicentre, which peaked in the hours before the quake. In other words, the atmosphere was heating up.

The WISE space telescope results go online

The WISE infrared space telescope results are now online, for anyone to search.

Data from the first 57 percent of the sky surveyed is accessible through an online public archive. The complete survey, with improved data processing, will be made available in the spring of 2012. A predecessor to WISE, the Infrared Astronomical Satellite (IRAS), served a similar role about 25 years ago, and those data are still valuable to astronomers today. Likewise, the WISE legacy is expected to endure for decades.
