Yes these type of events certainly get your attention and are definitely a wake up call!
I have now reassessed our position on being prepared for these types of mega-events. I plan on doing more fire mitigation efforts like taking out trees too close to house and possible installing a series of water holding tanks to fill with collected rainwater during rainy season. As well as buying a gas powered pump & fire hose in addition to reviewing our earthquake preparedness since we are considered to be in a potential earthquake affected area.
There is the
Cascadia subduction zone off the coast of WA, OR & Northern CA, that they say could trigger up to a 9.0 earthquake. That would take out all kinds of
infrastructure on the coast and possibly inland for months. However there is good news/bad news on the probably of such an event:
"In 2009, some geologists predicted a 10% to 14% probability that the Cascadia Subduction Zone will produce an event of magnitude 9.0 or higher in the next 50 years. In 2010, studies suggested that the risk could be as high as 37% for earthquakes of magnitude 8.0 or higher.
Geologists and civil engineers have broadly determined that the Pacific Northwest region is not well prepared for such a colossal earthquake. The earthquake is expected to be similar to the 2011 Tōhoku earthquake and tsunami, because the rupture is expected to be as long as the 2004 Indian Ocean earthquake and tsunami. The resulting tsunami might reach heights of approximately 30 meters (100 ft). FEMA estimates some 13,000 fatalities from such an event, with another 27,000 injured. It predicts that a million people will be displaced, with yet another 2.5 million requiring food and water.
An estimated 1/3 of public safety workers will not respond to the disaster due to a collapse in infrastructure and a desire to ensure the safety of themselves and their loved ones.
Other analyses predict that even a magnitude 6.7 earthquake in Seattle would result in 7,700 dead and injured, $33 billion in damage, 39,000 buildings severely damaged or destroyed, and
130 simultaneous fires."
So...my take away is, when your left on your own you are truly on your own and better be "prepared and able" to handle it.
