Like the early stages of the program in the U.S., the Japanese focused on prediction, with their major efforts targeting the Tokai area along the Nankai Subduction Zone southwest of Tokyo. The categories of potential assigned here provide a rationale for assigning prorities for instrumentation, for future studies aimed at predicting large earthquakes and for making estimates of tsunami potential.

One view is that the earlier earthquakes at Tokai in 1707 and 1854 were on local crustal faults, not the east end of the subduction zone, which implies that they would have no bearing on a future subduction-zone earthquake. One of the earliest and clearest applications of the seismic gap theory to earthquake forecasting was by McCann et al.

High priority should be given to instrumenting and studying several of these major seismic gaps since many are now poorly instrumented. This paper aims at analyzing the adequate required seismic separation gap between two adjacent Reinforced Concrete (RC) buildings by the equivalent static force method (ESFM). pure and applied geophysics "seismic gap Union59, 1125. data takes more time than usual to be analyzed. J. Roy. The absence of large earthquakes in one region along a tectonic front is called a seismic gap. Account for the following observations: H3PO2H_3PO_2H3PO2 is a monoprotic acid. A Dictionary of Earth Sciences. The applicability of this approach has been criticised by some seismologists[2] although earthquakes sometimes have occurred in previously-identified seismic gaps. The epicenter of the recent Acapulco earthquake lies at the eastern edge of the Guerrero Seismic Gap, a zone of apparent seismic quiescence embedded in this highly active seismic region.

In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. The term seismic gap is taken to refer to any region along an active plate boundary that has not experienced a large thrust or strike-slip earthquake for more than 30 years. ."
