A Geodynamic Network for the Monitoring of Seismo–Tectonic Activity Along the Mur–Mürz Fault Line (Austria)

The Mur-Mürz fault line is an active boundary between the geological units of the Eastern Alps and the Pannonian basin. Some moderate earthquakes shake this densely inhabited border area between Austria and Hungary every year, consequently special attention is paid for the research of its seismo-tectonic activity. Beyond the seismological monitoring the continuous observation of long periodic crustal deformations may efficiently help the understanding and interpretation of the mechanism of tectonic processes connected to the seismological events. Therefore, in the national networks of seismometers operated in and around the area (Vienna basin), three seismic stations were completed by high resolution tilt meters and two more independent tilt stations were installed on a 51 km by 25 km area in east-west and north-south directions, respectively, on both sides of the fault until 2023. This report shortly introduces the observations sites, their instrumentation and technical infrastructure as well as the processing methodology of the time series of recorded ground tilts. It also refers to the achieved results briefly.
