An Evaluation on the Behaviors of Aftershock Sequence of November 26th, 2019 Earthquake, ML=6.3, North of Durrës, Albania

(Kabul): 03.05.2021 ABSTRACT A comprehensive assessment of aftershocks occurrence for the November 26 th , 2019 earthquake, M L =6.3, 16 km north of Durrës, Albania was achieved. b -value was estimated as 0.88 ±0.07. b -value is close to 1.0 and relatively small b -value may be resulted from the plenty of larger aftershocks with M L  4.0. p -value was calculated as 1.23±0.08 with Mmin =3.1 and Tstart =0.0034 days. This high p -value may be a result of the relative fast decay rate of aftershock activity. Dc -value was calculated as 1.74±0.09 and it means that aftershocks are homogeneously distributed at larger scales. The smallest b -values and the largest p -values were observed in the north, northwest and northeast parts of the mainshock. The smaller b -values correlate with the larger stress variations, whereas the larger p -values are related to the maximum slip after mainshock. Consequently, region-time-magnitude analyses of the aftershocks occurrence may supply important clues for the fast evaluations of real
