We had some
questions in the past article: Is the 「gravitational
wave」 detected by America』s LIGO the 「earthquake precursor wave 」 only ? According
to this 「thinking」, we do a little bit investigations!
If the 「gravitational wave」 detected by America』s
LIGO on Sept. 14, 2015 at 09:50:45 UTC was one kind of 「earthquake precursor 」,
it should occur before a large earthquake, again if the 「gravitational wave」 was one kind of 「impending
earthquake precursor」, in that way it
should occur at a few days, for example 2 or 3 days, before a large earthquake.
At first,
let』s inquire large earthquakes over M7 in the world which occurred within half
a year before Oct. 26 , 2015 :
1.
A magnitude 7.8 earthquake struck Nepal 34 km
(21 mi) east southeast of Lamjung on
April 25 at a depth of 8.2 km (5.1 mi).
2.
A magnitude 7.5 earthquake struck Papua New Guinea 130 km
(81 mi) south southwest of Kokopo on
May 5 at a depth of 55.0 km (34.2 mi).
3.
A magnitude 7.3 earthquake struck Nepal 19 km
(12 mi) southeast of Kodari on
May 12 at a depth of 15.0 km (9.3 mi).
4.
A magnitude
7.8 earthquake struck offshore of Japan 189 km
(117 mi) west northwest of Chichi-jima in the Ogasawara Islands on
May 30 at a depth of 664.0 km (412.6 mi).
5.
A magnitude 8.3 earthquake struck Chile 48 km
(30 mi) west of Illapel on
September 16 at a depth of 22.4 km (13.9 mi).
6.
A magnitude 7.1 earthquake struck Vanuatu 34 km
(21 mi) northeast of Port Olry on
October 20 at a depth of 135.0 km (83.9 mi).
7.
A magnitude 7.5 earthquake struck Afghanistan 45 km
(28 mi) east of Farkhar, Farkhar district, Takhar province
on October 26 at a depth of 231.0 km (143.5 mi).
Why so fortunately? This is
occasional coincidence or correct thinking? A large earthquake of M8.3 occurred
in Chile which is 7000~8000 km far away from LIGO gravitational wave detectors
and just within 2~3 days after so-called gravitational wave arrived. The 「gravitational
wave」 event just fell into impending quake period of the large earthquake in
Chile, other large earthquakes in the
world within same half a year were far away from LIGO gravitational wave detectors
and were not within 2~3 days after that event.
It means that unique Chile earthquake which was closest from LIGO gravitational
wave detectors and the 「gravitational wave」 was detected within 2~3 days before
Chile earthquake. So that it may be a good idea that the 「gravitational wave」 detected by America』s
LIGO is one kind of earthquake precursor wave only!
According to our past experiments of earthquake prediction, it is not
strange that the detectors which is far away from the epicenter of M8
earthquake can receive the earthquake precursor wave (electromagnetic wave) from the emitter related with the M8 earthquake. On
the other hand, it is very strange that the instruments with high sensitivity cannot
receive any impending earthquake precursor wave from
M8 earthquake!
In conclusion, it is another possible option that the earthquake precursor wave just
are the signals detected by America』s
LIGO gravitational wave detectors.
