Abstract: | An analysis of the distribution (both spatial and temporal) of large earthquakes (M 6.5) along the Gissar—Kokshaal and the Hindu-Kush—Darvaz—Karakul fault zones in Middle Asia has revealed the linear character of migration from the ends to the centre of the Pamir arcs at a rate of 1–2 km/year to 3–6 km/year. Migration of large earthquakes at a similar rate has also been found in some of the other great fault zones. An attempt has been made to evaluate the duration of a migration cycle.The regularity found, although it needs further confirmation, has been used to tentatively predict the possible sites of future large earthquakes likely to occur in the present century. |
