MEGA TSUNAMI TO WIPE OUT FLORIDA?


o  Similarly, Cumbre Vieja Volcano on the island of La Palma in the Canary Islands, also off West Africa, is a particular concern for Simon Day and Steven Ward of the University of California. A combination eruption and landslide with a speed of 350 kilometers per hour would have an energy release equal to 6 months of electricity consumption in the U.S. Tsunami waves of up to 650 meters (2132 feet) would be created with a wavelength of 40 km (25 miles), traveling to West Saharan shores at an amplitude of 100 meters (328 feet), and Florida at up to 50 meter waves, eight hours later. On October 12, 2000, BBC2 showed, “Mega-tsunami: Wave of Destruction,” about this potential disaster, which became a most controversial TV program. This program is updated with regularity and again was shown in June of 2006.


A 164 foot tsunami would pretty much roll over all of Florida!  But my book discounted this potential as hyperbole, even after meeting with Bill McGuire of University College London, one of the co-authors.  Here is a 7 minute You Tube video explaining everything...by Bill.  Keep in mind that the largest possible earthquake (such as the 9.2 scale Indonesia monster of 26December2004--yikes, I'm posting this from this country) at the ocean bottom will only generate a wave, at most, of 10 meters (33 feet) in the far field (thousands of miles away).  A gigantic landslide can produce waves of several hundred feet.

Here is a recent clip of 13 minutes by Mary Greeley that sounds downright scary.  Not La Palma, but El Hierro (on the left) in the Canaries.  Scientific speculation is that both volcanoes share the same source of magma.  El Hierro has grown in elevation by at least two inches over the past few days  Mind you, her blog site is most definitely apocalyptic.  Yet, there too are reasonably ominous scientific reports.  Floridians will have eight hours of warning if something truly bad happens.

There is a long history of El Hierro (island to the right) earthquakes and eruptions, with three major subsequent landslides.  However, the most recent was 15,000 years ago.  Plus, there is no evidence of Florida ever being impacted by any tsunami from the Canary Islands.  But, it's something extra to be concerned about if you happen to live on the east coast of the USA, like a few of my friends...who I'll alert. 

Certainly, I wouldn't lose any sleep if you are reading this from the Canary Islands or Florida.  Hurricanes, maybe, but there are no imminent storms in the Atlantic.

The nature of the job of a transcriptionist is quite work intensive in terms of data storage and retrieval, and so potential medical transcriptionists are expected to be very organized, with a good sense of filing skills. Medical Transcriptionist Trainings in FL
