摘要：
In this work, we determined the coseismic slip distribution of the Boumerdes-Zemmouri earthquake (Mw 6.8, 2003) by inverting a most comprehensive set of data, teleseismic seismograms, strong motion seismograms, coastaluplift, Global Positioning System (GPS), and Interferometric Synthetic Aperture Radar. We suggest a best-fitting model of coseismic slip distribution on the following two segments: the first segment oriented at N70° and the second segment located at the west of the first one and oriented at N100°.The slip distribution shows two slip patches on the N70° segment containing the hypocenter. The eastern patch is shallower, located between 0 and 9 km depth, with a maximum slip of 2.30 m. The western slip-patch on this same segment is deeper, between 4 and 12 km depth, with a slip that reaches a maximum value of 2.70 m at the center. The N100° segment also displays two slip patches, a small one in the east of the segment, which is between 4 and 8 km depth and a larger one in the western part of the segment, between 0 and 10 km depth. Both patches associated with the N100° segment show a maximum slip between 1.10 and 1.40 m. © 2022, The Author(s), under exclusive licence to Springer Nature Switzerland AG.
