Abstract

Summary

The Klosi earthquake, which occurred on January 15, 2023, with a magnitude of 4.8 (Ms), affected central and northern Albania, as well as parts of Kosovo* and North Macedonia. This study focuses on the evaluation of its macroseismic field using online web survey data collected through IGEO and EMSC platforms. Over 80 questionnaires were analyzed to assess the earthquake’s intensity using the European Mediterranean Scale (EMS-98). The Klosi earthquake’s epicentral intensity (I) was estimated at 6.2, with a depth of 8 km. The spatial distribution of the macroseismic intensity was examined, revealing anisotropic components and random local variations based on responses from 20 municipalities. The study used a combination of empirical attenuation relations and statistical methods to model the macroseismic field and differentiate areas of amplification and de-amplification of seismic intensity. Results indicated that the attenuation was more pronounced in the northeastern part of Klosi, while the southern region exhibited lower attenuation, possibly due to varying crustal properties. This paper highlights the effectiveness of web-based macroseismic surveys in quickly seismic data collecting across large areas.
