• The work presents results of statistical analysis of the spatial-temporal distribution of strong aftershocks. Data from the world catalog of earthquakes USGS/NEIC from 1973 to 2014 (https://earthquake.usgs.gov) and from the regional earthquakes catalog of Northern California from 1968 to 2007 (http://www.ncedc.org) were used. Short time intervals were considered—no more than 10 h before and after main shock and distance from the epicenter of the main shock—up to 5°. The distribution of the aftershocks number in the time-distance coordinates from the main shocks was investigated. The main shocks with magnitude Mms ≥ 7.5 and aftershocks with 6 ≤ Maft < Mms for the world catalog NEIC USGS and the main shocks Mms ≥ 5 and aftershocks with 4 ≤ Maft < Mms for Northern California catalog were considered. It is shown that the spatial-temporal distribution of strong aftershocks forms a similarity of a wave structure.
