Review of Historical Earthquakes in the Lower Middle Ages: Earthquakes of the XIV and XV Centuries in Catalonia (NE Spain) - Historical Seismology: Interdisciplinary Studies of Past and Recent Earthquakes - page 145

The joint interpretation of all the large middle ages earthquakes in Catalonia such
as those in 1427, 1428 and 1448 (Olivera et al. 2006) provided new information that
enabled us to re-evaluate the main earthquake of 3 March 1373. Site intensity values
in the earlier study have been re-evaluated and some new intensity data points have
been added. Moreover, quality index for every intensity value has also been assigned.
Olivera et al. (1994) did not determine epicentral location but only indicated a roughly-
defined epicentral are. This new analysis allowed the epicentre to be located on the
North boundary of the earldom of Ribagor¸a. Although the earthquake was felt up to
360 km away from the epicentral area, the number and geographical distribution of
localities where the intensity is known are quite small as shown in Fig. 2.
