Migration Of Earthquakes

The analysis of data on the migration of earthquakes and slow deformations from the Indo-Eurasian collision and the Western Pacific subduction zones is given, and the wave “geodynamic impact” of these tectonic processes on the Amurian plate and surrounding structures is shown. The interaction and a relative contribution of collision and subduction to the recent geodynamics of the Amurian plate are discussed. A scheme is constructed showing localizations of the slow strain wave manifestation in the areas of central and eastern Asia. The calculations are performed aimed at revealing a transverse migration of earthquakes (M ≥ 6.5) directed from the Japan and the Kuril-Kamchatka trenches toward the Asian continent during the time period from 1960 to 2015. The migration of earthquakes along the profile crossing Hokkaido Island occurs at velocities of 15 and 23 km/yr, whereas the migration velocity from the Kuril-Kamchatka Trench via Sakhalin Island is evaluated from 20 to 40 km/yr at different depths. We focus on an insufficient study of the influence of the Western Pacific subduction on the formation of the deformation field in continental Asia.

Migration Of Earthquakes

The analysis and processing of 1135 microearthquakes, recorded during the time period May 1993 – December 1994, indicated that the North Aegean Trough and the Trough of Skyros are the boundaries of, respectively, the NW and SE side of a tectonic Block in the shape of a trapezium, whose large base is the NW one. ΝW of the island of Lemnos, the North Aegean Trough changes direction from ENE-WSW to NE-SW. This point operates as a joint, on either side of which a differentiation of the areas is visible. In the SW of the troughs, two seismic gaps, which seem to be connected to a presently shaping channel of a NW-SE trend, were observed. The two southern branches of the North Anatolia Fault will constitute, in future, the northern and southern boundary of the Trough of Skyros. The migration of earthquakes in the North Aegean Sea follows a right lateral direction, however this direction changes to left lateral east of Chios Island.
