In Tokyo, there was damage to , , , and the walls of. important;-webkit-box-shadow:none! As late as July 2013 slightly elevated levels of radioactivity were found in beef on sale at Tokyo markets. Such discrepancies in the warning were attributed by the JMA to the system's inability to distinguish between two different earthquakes that happened at around same time, as well as to the reduced number of reporting seismometers due to power outages and connection fails. Another cause of delayed evacuations was the release of the second update on the tsunami warning long after the earthquake 28 minutes, according to observations ; by that time, power failures and similar circumstances reportedly prevented the update from reaching some residents. from the original on 15 March 2011. There was a great deal of damage to buildings on the islands and one man was injured but there were no reported fatalities. animate-line:not :last-of-type :after,. Most tsunamis, like the one that formed off Tohoku, are triggered by underwater , such as earthquakes and s. Three tsunami deposits have been identified within the Holocene sequence of the plain, all formed within the last 3,000 years, suggesting an 800 to 1,100 year recurrence interval for large tsunamigenic earthquakes. The discrepancy arose as follows: in order to produce a quick prediction of a tsunami's height and thus to provide a timely warning, the initial earthquake and tsunami warning that was issued for the event was based on a calculation that requires only about 3 minutes. JMA also implemented a simpler empirical method to integrate, into a tsunami warning, data from GPS tidal meters as well as from undersea water pressure meters, and there are plans to install more of these meters and to develop further technology to utilize data observed by them. Investigations were continuing to make sure there was no structural damage, he added.
