Published: August 23, 2010 from Barkley32002 Noticing a Magnitude-8.0 Earthquake Months Later Noticing a Magnitude-8.0 Earthquake Months Later To the amazement of seismologists, they missed a magnitude-8.0 earthquake last year. “It is sort of shocking,” said Thorne Lay, a professor of earth and planetary sciences at the University of California, Santa Cruz, who led a team that uncovered the seismic fingerprints months later. “If we hadn’t done the careful analysis, we would have missed it.” Magnitude-8 earthquakes are known as great earthquakes for their ferocious destructive power, and networks of seismometers can pinpoint much smaller earthquakes. In this case, however, the great earthquake was hidden by a greater quake. The greater earthquake, of magnitude 8.1, struck Sept. 29, 2009, off the Samoa Islands in the Pacific. That in itself was a surprise to seismologists, because there have not been any known magnitude-8 earthquakes around the Tonga trench, where the Pacific plate slips beneath the Australian plate, leading seismologists to believe that the fault there is well lubricated and does not build up enough stress to generate great earthquakes. Still, the two tectonic plates are speeding toward each other there faster than anywhere else in the world, some 10 inches a year. The resulting tsunami, which swept into Samoa, American Samoa and Tonga, killing more than 100 people, also puzzled scientists. The magnitude-8.1 earthquake did not occur at the plate boundary …
Part 1: Sometimes the city is a bad place to be. But millions find themselves linked to the city, living, working, or recreating. Cessation of services, terrorists attacks, economic or governmental collapse, rioting (for a variety of reasons), and devastating NATURAL disasters can transform a usually-bustling and mostly safe urbanscape into a wasteland where emergency services are either overwhelmed or just unavailable. You may quickly find your survival (and those around you) will be up to you. Go prepared, both with a calm, can-do mindset that will allow you to overcome, adapt, and survive bad situations (and help others to do the same). In this series of vids, I introduce my “Concept USK” or Urban Survival Kit and its philosophy as requested by many TNPrs. A possible motto as you work your way through urban chaos: “Prepare, Survive, Render Aid, Lead.” Some Nutnfancy foundations of the review: most kits will evolve according to need and technology, a kit will have to be personalized for your situation, adherence to legalities of some contents is your responsibility, it’s impossible to prepare for every contingency and SAWC (Space/Size And Weight Constraints) will dictate your level of preparation and kit “depth,” preparations for self-defense are wise, the necessity to blend in and not draw attention to yourself, the concepts of “write-off,” re-stocking, pre-postioning, and redundancy in kit preparation, and guidelines for use. In Part 1 these foundations are discussed …
