"There were hardly any people living on the Pacific  Northwest Coast in 1700," said Heidi Houston, a seismologist at the  University of Washington's Department of Earth & Space Sciences.  "But it generated a huge tsunami that traveled to Japan and destroyed  coastal villages there. The Japanese records show that the causative  earthquake could only be our Cascadia Subduction Zone and it had to have  been a magnitude-9.0."                   <a href="http://www.google.com/url?ct=abg&q=https://www.google.com/adsense/support/bin/request.py%3Fcontact%3Dabg_afc%26url%3Dhttp://www.livescience.com/13274-magnitude-9-0-earthquake-locations.html%26hl%3Den%26client%3Dca-pub-1894578950532504%26adU%3Dwww.SmartPlanet.com%26adT%3DPrepare%2Bfor%2Ba%2Bdisaster%26gl%3DLK&usg=AFQjCNFJ_TNcxi3WOpMpnz0xi6Tr7yA6nA" target="_blank">Ads by Google</a><a href="http://googleads.g.doubleclick.net/aclk?sa=L&ai=BfFcpGM-BTf68OIOxcKD9mPkO1JWA8AG8rNrgF8CNtwGQThABGAEg8pn0ATgAUO--i4UFYJGB7ASyARN3d3cubGl2ZXNjaWVuY2UuY29tyAEB2gFIaHR0cDovL3d3dy5saXZlc2NpZW5jZS5jb20vMTMyNzQtbWFnbml0dWRlLTktMC1lYXJ0aHF1YWtlLWxvY2F0aW9ucy5odG1sgAIByAL8mv0ZqAMB6AOtCegDuwPoAwz1AwAAAET1AxAAAAE&num=1&sig=AGiWqtxDEJC8_VX_E62Sr7cSpcdezp6-Nw&client=ca-pub-1894578950532504&adurl=http://www.smartplanet.com/people/blog/pure-genius/a-disaster-is-coming-youre-not-prepared/4178/" target="_blank">Prepare for a disaster</a>Americans aren't prepared for the next mega-disaster.

Because the last one happened in 1700, "that means sometime in  the next 400 years it will happen again," Houston told <a href="http://www.lifeslittlemysteries.com/containment-breach-fukushima-implications-1465/" target="_blank">Life's Little Mysteries</a>, a sister site to LiveScience.      Scientists aren't able to provide a more specific time frame than that.  They know what conditions must be present in an area to lead to massive  earthquakes, but, according to Nathan Bangs, a geophysicist at the  University of Texas, "it's hard to do useful predictions."      "The low-lying areas have deposits that give a record of repeated  history of tsunami inundations, and how big they were. That means you  may know the likelihood on the order of hundreds of years, but it  doesn't give the likelihood in the next few years," Bangs explained.      A 9.0 earthquake is also possible in Alaska, the <a href="http://www.lifeslittlemysteries.com/whats-the-most-earthquake-prone-state-in-the-us-0250/" target="_blank">most earthquake-prone state</a>  in the U.S. In 1964, the Aleutian fault separating the Pacific and  North American plates ruptured near the city of Anchorage, resulting in a  9.2-magnitude earthquake – the second largest ever recorded on a  seismograph.      The San Andreas Fault, commonly perceived to be more dangerous than the  Cascadia Fault because of the proximity of several major California  coastal cities, is not actually capable of generating a 9.0-magnitude  earthquake. "The biggest one there would be just under 8.0," said  Houston.මේක වෙන්නැති මගේ හිතේ ඔය ගොයියා කියනවා ඇත්තේ....<img src="/styles/default/xenforo/smilies/default/lol.gif"  class="smilie" loading="lazy" alt=":lol:" title="LOL    :lol:" data-shortname=":lol:" /><img src="/styles/default/xenforo/smilies/default/lol.gif"  class="smilie" loading="lazy" alt=":lol:" title="LOL    :lol:" data-shortname=":lol:" /><img src="/styles/default/xenforo/smilies/default/lol.gif"  class="smilie" loading="lazy" alt=":lol:" title="LOL    :lol:" data-shortname=":lol:" /><img src="/styles/default/xenforo/smilies/default/lol.gif"  class="smilie" loading="lazy" alt=":lol:" title="LOL    :lol:" data-shortname=":lol:" />ඔය තියෙන්නෙ සහසුද්දෙන්ම දාලා.. 16 වැනිදා සුද්දො කිව්වා...17 වැනිදා අපේ කළු සුද්දා කිව්වා...<img src="/styles/default/xenforo/smilies/default/P.gif"  class="smilie" loading="lazy" alt=":P" title=":P    :P" data-shortname=":P" /><img src="/styles/default/xenforo/smilies/default/P.gif"  class="smilie" loading="lazy" alt=":P" title=":P    :P" data-shortname=":P" /><img src="/styles/default/xenforo/smilies/default/P.gif"  class="smilie" loading="lazy" alt=":P" title=":P    :P" data-shortname=":P" /><img src="/styles/default/xenforo/smilies/default/P.gif"  class="smilie" loading="lazy" alt=":P" title=":P    :P" data-shortname=":P" />කටියට ඉන්ගිරිසි  තේරුම් ගන්න අමාරුවෙයි කියල ඒක සින්හලෙන් දාලා තියෙන්නෙ..පව් බන්...<img src="/styles/default/xenforo/smilies/default/rofl.gif"  class="smilie" loading="lazy" alt=":rofl:" title="ROFL    :rofl:" data-shortname=":rofl:" /><img src="/styles/default/xenforo/smilies/default/rofl.gif"  class="smilie" loading="lazy" alt=":rofl:" title="ROFL    :rofl:" data-shortname=":rofl:" /><img src="/styles/default/xenforo/smilies/default/rofl.gif"  class="smilie" loading="lazy" alt=":rofl:" title="ROFL    :rofl:" data-shortname=":rofl:" />මේක දාල තිබ්බේ අපේ shehan360  <img src="/styles/default/xenforo/smilies/default/yes.gif"  class="smilie" loading="lazy" alt=":yes:" title="Yes    :yes:" data-shortname=":yes:" /><img src="/styles/default/xenforo/smilies/default/yes.gif"  class="smilie" loading="lazy" alt=":yes:" title="Yes    :yes:" data-shortname=":yes:" /><img src="/styles/default/xenforo/smilies/default/yes.gif"  class="smilie" loading="lazy" alt=":yes:" title="Yes    :yes:" data-shortname=":yes:" /></blockquote>
