Abstract The 19 November 1923 earthquake in the Aran Valley (Central Pyrenees), with observed maximum intensityI max = VIII (MSK), has been studied through the compiling and reviewing of macroseismic information and collecting and processing early seismograms. Analysis of macroseismic data gives a focal depth ofh = 5 km and an anelastic attenuation coefficientα ≤ 10−3 km−1. Analysis of early instrumental records allows the computation of estimate of magnitude (M L = 5.6) and seismic moment (M o = 1.1 × 1017 N × m) which are consistent with the values ofI o andh obtained from macroseismic data.
