t has been barely a month since a magnitude-9.0 earthquake and subsequent tsunami devastated Japan, killing at least 12,800 people. But scientists are already coming out with research about one of the worst natural disasters in history. Some of those findings will be released during the annual meeting of the Seismological Society of America, which gets under way today in Memphis, Tenn. The society released this snapshot of some of the research papers about Tohoku, the name given to the event. The summaries are often verbatim ....

Two days before the devastating Japanese earthquake and tsunami, there were foreshocks off the Pacific coast of Tohoku. Yoshiaki Fujii of Hokkaido University notes that the daily rate of small earthquakes (equal or more than magnitude-1.0) significantly increased two days before the main quake. A large number of these foreshocks were detected in Miyagi, Iwate and Fukushima, site of the dangerously crippled nuclear power plant.
