Japan aftershocks expected to reach magnitude 7-8

For Japan, it's nowhere near over, at least if the Pasadena Jet Propulsion Laboratory is correct. While Japan has experienced numerous magnitude 5 and 6 aftershocks (405 in total to be precise), the big ones are still to come: "Japan's largest quake on record, which hurled a 7-meter (23-foot) wave landward after one plate slid beneath another off the coast of Sendai, had an 8.9 magnitude.The aftershocks will likely include at least one measuring 8 and 10 of magnitude 7, JPL geophysicist Andrea Donnellan said. All are many times larger than the 6.3-level New Zealand quake in February that leveled the Christchurch business district and killed 160."
