In any case, here is the rather simple Planet Earth and Humanity posting I had on 27 February 2010, which drew 3,356 visitors, a total that was not exceeded until this year, when one day it zoomed up past 25,000...and the subject matter had to do with Star Wars.
As of 12:20PM, there was a recession of 3 feet and a rise of 3 feet around Hilo. Thus, it's official, a reasonably significant tsunami affected Hawaii.
Thank heavens, the 35-foot Hilo monster of 1960 (the photo to the right) did not materialize this time. At this point, nothing official from a largely abandoned (one person was shown walking to the shore) Waikiki Beach, although there are three surfers awaiting something. Not too smart. The reef off Ala Moana Beach did show for a while, exhibiting some receding waters.
Okay, that was my most popular posting for almost nine years. For informational purposes (from my article on 31May2015 on SAN ANDREAS):
- Subtract the smaller earthquake from the larger.
- Multiply this difference by 1.5.
- Place this number into the exponent of base 10.
- Soon after the 9.0 magnitude Great Tohoku earthquake of 2011, I was in Tokyo and was jarred by a 7.1 magnitude earthquake. What was the energy ratio?
- 9.0 - 7.1 = 1.9
- 1.9 x 1.5 = 2.85
- 10**2.85 = 707
- As serious as a 7.1 magnitude earthquake is, it is 707 times weaker than a 9.0.
Note that this 2010 Chile earthquake is called by various different names. It was the 7th largest in recorded history.
no pre-historic earthquakes even close to the Valdivia 9.5. For example, in 1201 or 1202, an earthquake in Egypt/Syria killed 1.1 million (mostly from famine/disease), but only was estimated to be of 7.6 moment magnitude. That total is greater than the 825,000 deaths of the 1556 Shaanxi earthquake, which is listed as the most devastating.
deaths occur from natural disasters:
- Flood (China, July 1931): one to four million (China has the worse four floods)
- Famine (China, 1958 to 1961): 15 to 43 million (I was in high school and don't remember this)
- Astronomical fall (1490 Ching-yang event): 10,000 (meteor shower)
- Avalanche (Peru, 1970): 20,000 (following an earthquake)
- Heat wave (Europe, 2003): 70,000 (I was in Europe that summer, and it was, indeed, hot--for farmers in Ireland were told to apply sun tan lotion to cow udders--but was not aware so many people died)
- Cyclone (Pakistan, 1970): more than half a million
- Tsunami (Greece, 365AD, from Crete earthquake): 400,000 (the 26December2004 Sumatra earthquake and tsunami is #2 with 280,000 deaths)
- Volcanic eruption (Indonesia, 1815): more than 71,000
