AIR Worldwide has updated its Earthquake Model for Japan following the Tohoku earthquake of March 2011.

The new model implements the ground motion data, damage observation and claims information gathered after Tohoku, a magnitude 9.0 quake that set off a massive tsunami off the Japanese coast and caused an estimated $30.7 billion in insured losses, according to AIR.

"AIR seismologists undertook an intensive reexamination of information from various sources, including physical and statistical models that calculate how the Tohoku rupture affected stress accumulation on nearby faults," said Jayanta Guin, senior vice president of research and modeling at AIR Worldwide.
