Japan to Release Notices on Big Nankai Trough Quakes within Hours of Abnormality (News)
Tokyo, Oct. 26 (Jiji Press)—The Japan Meteorological Agency said Thursday it will work to disclose its assessment of abnormal phenomena that could possibly lead to a massive earthquake along the Nankai Trough off the Pacific coast from central to southwestern Japan as early as two hours after observing such precursors.
The agency plans to initiate the scheme on a provisional basis at noon Wednesday (3 a.m. GMT).
The new program comes after the government last month decided to review its disaster management measures for the so-called Tokai earthquake, a possible powerful temblor focused on Shizuoka Prefecture, central Japan, based on the special law on responses to large-scale earthquakes.
Among the three major scenarios the agency assumes is that a magnitude-8 level earthquake that occurs in the east side of the Nankai Trough may trigger an earthquake in the west side.
The other two scenarios are that a magnitude-8 level main temblor may occur after a magnitude-7 level foreshock and that the agency observes an abnormal slide of oceanic and continental plates there.[Copyright The Jiji Press, Ltd.]
