News in Science Mega-quakes rare but can occur anywhere We can expect an average three catastrophic, magnitude 9 or greater earthquakes around the world each century, according to a new study. "The Sumatra-Andaman earthquake happened in one of the least likely places," says seismologist Dr Robert McCaffrey of New Zealand's government research agency GNS Science. As for why McCaffrey's model came up with fewer magnitude 9 quakes than have been seen in the past 50 years, that's just a matter of the sample size, he says. The next tsunami "His argument is, anywhere you have a subduction zone you can't exclude the possibility," says seismologist Professor Seth Stein of Northwestern University.
