Review of earthquake location quality since 2020 for Austria

When monitoring seismicity, detection thresholds for magnitude and location accuracy for epicentres are basic quality factors used. However, these factors can be estimated in numerous ways, depending on available data, the tasks the network is built for and customer/legal guidelines.

In this work, we focus on location quality. We analyse location quality for the area of Austria and a smaller project within. For this purpose, we calculate location errors with NLLoc (Lomax, et al. 2009) for Austria and compare them with location errors automatically computed for each earthquake located by the Austrian Seismological Servicewithin the last 2 years. Additionally, we use the quality parameters given in Bondar, et al. (2004) for further analysis.
