Friends,
This is a follow-up to my previous report about the upcoming 9.5 Mega-Quake to strike Japan
That upcoming July 23rd 9.5-magnitude earthquake will tie the world record for the largest-ever earthquake.
(That other earthquake was in 1960 in Chile: the Valdivia (Great Chilean) Earthquake. Details of what the effects of that Valdivia 9.5 Earthquake (also along a coastline) were like can be found below * ) .
I have taken the energy reading of the upcoming July 23 Japan Great Quake and pinpointed its location.
The July 23rd Earthquake's epicenter will be in the off-shore Pacific Ocean 100 km (62 miles) east of Minamisanriku, a village along the northeast coast of Japan's main Honshu Island, and 60 km (37 miles) northeast of Sendai.
Minamisanriku is only 25 km (15 miles) north of the Onagawa nuclear power plant, already somewhat damaged by the March 11th monster quake, which also severely damaged several nuclear reactors at the Fukushima nuclear power plant complex. And this July 23rd Mega-Quake will be six times as strong! The Japanese Government should shut down the Onagawa nuclear plant that weekend as a precaution.
The July 23rd Quake will cause ground shaking 6 times as strong as on March 11. Since Tokyo is only 320 km (200 miles) southwest of the epicenter, Tokyo can expect to receive damage this time.
There will also be resulting tsunamis very much larger than those on March 11. For some idea of the scale of potential tsunami effects, see the description of tsunamis created by the other 9.5 Great Quake, in Chile 51 years ago (below)*.
This July 23rd Quake will be caused by a larger tectonic plate movement than caused the earlier quake on March 11th: the violent sudden subduction of the Pacific Plate edge under the Okhotsk Plate that Japan rests on, with additional pressure provided by the Philippine Sea Plate at the area's triple-convergence zone.
How can people on Honshu Island, Japan prepare for the truly Big One coming about six weeks from now?
They have had a learning experience from the Match 11th quake. All the prudent precautions one takes in a major earthquake are in order. Since the timing of this 9.5 Quake is known, if I were living on northern Honshu, I'd make sure not to be in, or sleep in, a building made of rigid unyielding structure such as masonry or steel that weekend. Near the epicenter, even being in a wooden house might not be safe enough. One can always sleep outside that weekend; it'll be warm.
Then there is also the issue of the much larger tsunamis coming this time. Using the 1960 Valdivia 9.5 Quake as a model, it generated local tidal waves 25 meters (82 ft) high. But in the March 11 Japan Quake, tsunami heights varied widely depending on topography, and ranged up to 30 meters (100 feet) high. Since the upcoming July 23 Quake will be 6 times as strong, even larger waves may be expected, and may travel farther inland.
Thus in addition to staying out of places subject to failure in the earthquake, north Honshu residents would do well to stay away from low-lying coastal areas that weekend.
As for other countries' citizens living near the Pacific, it would be prudent to look up the tsunami warning map put out by USGS 's Pacific Tsunami Warning Center right after that July 23rd Quake hits, at: http://ptwc.weather.gov/?region=1. That map will show you where a tsunami propagated from Japan could strike. And this time the wave heights are likely to be much higher than on March 11th. So, even people as far away as coastal Alaska, Hawai'i, the Pacific coasts of North, Central, and South America, New Zealand, Indonesia, and the Philippines should inform themselves about potential oncoming risks.
