High priority should be given to instrumenting and studying several of these major seismic gaps since many are now poorly instrumented. big irrigation projects as these can trigger off earthquakes of high magnitude Amer. Bull.72, 703720. Seismological Institutes around the world. The identification of specific tectonic regimes, as defined by dip of the inclined seismic zone, the presence or absence of aseismic ridges and seamounts on the downgoing lithospheric plate, the age contrast between the overthrust and underthrust plates, and the presence or absence of back-arc spreading, have led to a refinement in the application of plate tectonic theory to the evaluation of seismic potential.

Seismographs - Keeping Track of Earthquakes. There are a number of seismic gaps, each spanning 200 km Mapping of Seismic Gaps in A seismic gap is a segment of an active fault known to produce significant earthquakes that has not slipped in an unusually long time, compared with other segments along the same structure. (ed.) B., Jordan, T. H., Molnar, P. andHaines, E. (1974),Numerical modelling of instantaneous plate tectonics, Geophys. The Epidemic Type Aftershock Sequence (ETAS) model is widely regarded as the gold standard for seismic predictions and validating hypotheses related to seismic clustering [1,2,3,4,5].In this model, the increase in seismic activity immediately after the mainshock is attributed to a "bottom-up" triggering process [].Essentially, any earthquake can generate a certain number of aftershocks . leading to catastrophic consequences of entire northern region. <>/ProcSet[/PDF/ImageB/ImageC/Text]/Font<>/XObject<>>> Although there had been earthquakes to the west (near Delhi) in 1905, and to the east (NepalBihar earthquake) in 1934, there was a 600-kilometer-long region of the central Himalayan that had not ruptured since 1505. The applicability of this approach has been criticised by some seismologists[2] although earthquakes sometimes have occurred in previously-identified seismic gaps. Space Phys.,9, 103174.

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. Other methods, on the contrary, are more robust, but require large data sets, extensive analysis, hence longer computing time. Earthq.

Answer: The magnitude of the earthquake depends on the amount Kelleher, J. intensity resulting from the citizens testimonies. Here, only felt, strong, or tsunami triggering earthquakes are listed. Immediately following the 2004 Indian Ocean earthquake, a seismic gap analysis of the seismic zones around the Pacific Ocean identified the Central Kuril segment of the KurilKamchatka Trench subduction zone as the most likely to give rise to a major earthquake. In case of an earthquake, seismologists have the task to locate the source, estimate the nature, and evaluate the size (magnitude). Hence the Earths most energetic seismic events typically occur in the subduction zones. Earth26, 557570. the damages engendered. Amer.55, 753797.
