Japan: Earthquakes and Aftershocks in Japan in 2011 Were Seven Times Higher Than 2010


“TOKYO — The Meteorological Agency said Thursday that 6,757 aftershocks were felt in Japan after the March 11 disaster through Dec 31.

Of those, there were 14 with a magnitude over 5, 30 with a magnitude of 5, 174 with a magnitude of 4, 707 (magnitude 3), 1,904 (magnitude 2) and 3,928 (magnitude 1), the agency said on its website.

For the whole year, the agency said there were 9,723 earthquakes and aftershocks, seven times the number in 2010.

An agency official said that although the number of aftershocks has been decreasing, it will be many years before seismic activity returns to pre-March 11 levels.” Source – Japan Today.

Japan, NZ quakes set insurance record – “The devastating earthquakes in Japan and New Zealand made 2011 the costliest year yet for the insurance industry in terms of natural disaster losses, a leading reinsurance company says. Munich Re said in an annual report that insured losses last year totalled US$105 billion ($133 billion), exceeding the previous 2005 record of US$101 billion, when losses were swollen by claims from Hurricane Katrina in New Orleans. The company said the total economic cost last year from natural disasters – including uninsured losses – totalled about US$380 billion. That was far above the 2005 record of US$220 billion.” Read more.
