The “MS Moon-Phase Double Time Method” is used for long-term/medium-term predictions to predict the high risk dates of possible strong EQs ≥Ms7.5 (and certain EQs Ms7.0 – 7.4) occurring global wide.
By this method itself, the most likely locations of such EQs can not be predicted.
However, Shen has been using the “Long-term EQ Cycles” to predict one or more most likely locations of the possible EQs ≥Ms7.5 (and certain EQs Ms7.0 – 7.4) occurring global wide.
6.1. The duration “Long-term EQ Cycles”: A few dozen years.
The “MS Moon-Phase Double Time Method” can only predict the possible occurrence dates of worldwide strong EQs ≥Ms7.5. What could we do to estimate the possible locations?
In late 1960s, a research group named “223” was established in China specially to study relativities between EQs and astronomy cycles. In 1969 they internally published a paper “Preliminary analysis of the relativities bewteen the Xingtai EQ and universal events”.
Enlighten by their work, during 1977 – 1987 Shen began to carefully study the “Long-term EQ Cycles” of major EQs in different areas in China, and abroad.
On the basis of such studies, beginning in the early 1990s, Shen used his “Long-term EQ Cycles” analysis to predict the possible locations of major EQs he predicted by the “MS Moon-Phase Double Time Method”.
Table 13 The “Long-term EQ Cycles”: West of China and nearby area
A 21 – 22 year cycle is apparent in the West of China and nearby area.
21-22 years, however, correspond to about twice the duration of the solar activity cycle, i.e. 2 x 11 yrs = 22 yrs.
Table 14 The “Long-term EQ Cycles”: Taiwan and nearby area
A 49 - 52 year cycle is apparent in the Taiwan area.
Table 15 The “Long-term EQ Cycles”: USA West coast and nearby area
A 21 - 22 year cycle is apparent in the USA West Coast area.
21-22 years, again, correspond to about twice the duration of the solar activity cycle, i.e. 2 x 11 yrs = 22 yrs.
Table 16 The “Long-term EQ Cycles”: Japan and nearby areas
Japan and nearby areas
A 50 - 51 year cycle is apparent in Japan and nearby area.
Table 17: The “Long-term EQ Cycles”: Chile and nearby area
A 21 - 22 year cycle is apparent in Chile and nearby area.
Table 18 The “Long-term EQ Cycles”: Turkey and nearby areas
A 59 - 60 year cycle is apparent in the Turkey and nearby area.
Note: 2002-2004 is a high risk duration.
Suggestion:
A number of Chinese EQ prediction practicer experts of the “Natural Disaster Prediction Committee” of the Geophysics Society of China, including EQ prediction practice experts in long-term, medium-term, short-term and EQ Imminent phase predictions, are willing to cooperate with Europe colleagues under a Sino-European cooperation project, to “catch” such a possible major EQ.
