The Good Earth has not been kind to NASCAR this year. First we had the pothole that delayed the Daytona 500 for more than two hours. And now comes word that a gargantuan sinkhole has opened up in the infield at Charlotte Motor Speedway.
Otto makes the 15th named storm of the 2010 Atlantic hurricane season. Named storms include tropical storms and hurricanes.
According to James Hansen, the director of NASA's Goddard Institute for Space Studies (GISS), 2010 may not wind up being the hottest year in the modern temperature record after all. In an analysis posted last week,
Selected earthquakes of general historic interest.
You may have heard about the sinkhole that developed in one of our infield display areas last Friday night due to recent heavy rains. The area was over a landfill and we found a 30 year old drain pipe that had deteriorated more than 35 feet below the ground surface.
Hurricane season in the Atlantic begins June 1st and ends November 30th. The Eastern Pacific hurricane season begins May 15th and also ends November 30th.
August 27 1964 - First tornado death in state
A tornado moved through an Indian village southwest of Tucson demolishing four homes, killing two people and injuring eight, all from one family. This was the first tornado reported in Arizona that cuased a death. Property damage was done to the convent of the Nuns of St. Francis. The nearby historic San Xavier Mission escaped with only minor structural damage.
June 23 1974 - Tornado kills one and injures 40
One man was killed and 40 people were injured as a tornado ripped through a mobile park about one mile west of the historic San Xavier Mission, southwest of Tucson. The tornado was estimated to be on the ground for three minutes and destroyed 19 mobile homes with severe damage to 50 others. Three additional tornadoes were spotted and reported to law enforcement officials between 330 PM and 4 PM.

That link is broken (?) I got this when I clicked it:
SOME 16 million years ago, north became south in a matter of years. Such fast flips are impossible, according to models of the Earth's core, but this is now the second time that evidence has been found. The magnetic poles swap every 300,000 years, a process that normally takes up to 5000 years. In 1995 an ancient lava flow with an unusual magnetic pattern was discovered in Oregon. It suggested that the field at the time was moving by 6 degrees a day - at least 10,000 times faster than usual. "Not many people believed it," says Scott Bogue of Occidental College in Los Angeles. Now Bogue and his colleague Jonathan Glen of the United States Geological Survey in Menlo Park, California, say they have found a second example in Nevada. The lava rock suggests that in one year, Earth's magnetic field shifted by 53 degrees (Geophysical Research Letters, DOI: 10.1029/2010GL044286). At that rate, a full flip would take less than four years, but there could be another interpretation. "It may have been a burst of rapid acceleration that punctuated the steady movement of the field," says Bogue. Peter Olson of Johns Hopkins University in Baltimore, Maryland, remains sceptical and points out that the effects could have been local rather than global. Earth is overdue for a reversal, and rapid shifts would cause widespread chaos - for navigation and migratory birds for instance.

Oh my. That is frightening. Tell me, oh please tell me. How may I save myself?
BTW, that earthquake graph is meaningless. Its source does not list all earthquakes.

The thing is we know that magnetic reversals happen. In fact they're not that rare at all. If one were to occur it would be relatively benign. What the OP seems to be suggesting is a TPW, where the crust itself actually shifts. This would theoretically cause problems. I say theoretically because one has never occurred. There is some literature on them, but most of the claims seem to be coming from fringe sources.
