Survivalists in Florida

May 19, 2012 – 11:49 pm | One Comment

Great article in the Miami New Times last week, profiling preppers and survivalists like these folk:
Jorge Villa – after a terrifying experience during Hurricane Andrew he devised his own bunkers, and sells them to folk – some of whom are worried about the end of the Mayan calendar – via his business U.S. Bunkers
Neal Wiseman – moderates a group called the South Florida Survivalist Network, and has a year’s worth of food stored for his family, should the need arise:

Chris Petrovich – prepper for 25 years. He has helped others “cache extra fuel and food, stashed in public-storage units and underground, at intervals on an 800-to-1,200-mile path out of Florida. Amid darkness and chaos, skirting burning sugarcane fields and accidents and roadblocks, they’ll drive from cache to cache toward a secret inland hiding spot, exhausting the last available remnants of the petroleum age.”
While Petrovich himself plans on staying, I agree with …

More likely during eclipses and perhaps Comet Elenin is a factor?

Asteroid Tsunamis Not So Bad After All?

Submitted by Robert Bast on April 28, 2009 – 7:36 amOne Comment

A new computer simulation has determined that if a 200 metre wide asteroid lands in the ocean, where the water depth is 5 kilometres, the following will occur:

  • Initial tsunami with a height of hundreds of metres
  • The height of the waves makes them prone to collapse, and they start breaking immediately
  • After they are 30 kilometres from the impact site, they have shrunk to a height of less than 60 metres
  • Extrapolating the shrinkage suggests a height of less than 10 metres after it has travelled 1000 kilometres

Ultimately, how close to the shore the impact is would make a big difference…

Although 10 metres would ordinarily mean massive devastation, apparently the wavelength would be shorter (2 minutes), and therefore not as damaging as regular tsunamis (8 minutes). The results of another simulation “suggest much slower wave decay”, ie worse.

The article concludes with something we all, perhaps, should keep in the back of our mind:

Brian Toon of the Universityof Colorado in Boulder says we should continue surveying for asteroids. “We probably have quite a while before we’re going to get hit by a significantly sized [asteroid],” he says. “But nevertheless one of these is going to come at us.”

  • Carl says:

    Based on the fact that the Pacific, the largest and deepest ocean on the planet has an average depth of 13,215 feet (4400 metres)this would mean that the majority of this same expanse of water would be a great deal shallower. The same could be said for the remaining 4 oceans. Why then would anyone base a calculation on 200m asteroid landing in water 5 kilometers deep??
