New paper! Seismicity in a coal mining region: induced, triggered or natural? We found many arguments that more than a century of mining triggered seismicity in the Hainaut coal region (Belgium): shallow depths, local impact, focmec in line with local stress state... @seismotom.bsky.social
We thank the #AHEAD initiative as the database was opened using the MIDOP software, designed by Mario Locati #INGV. This paper and work results from the PhD research of Ben Neefs and was funded entirely by the @orb-ksb.bsky.social !
The BTM database allows the Belgian population to find answers to questions like:
o How many earthquakes were felt in your municipality in the twentieth century?
o Which earthquake had the largest impact on your municipality?
o What was the largest magnitude of an event in your region?

We invite you to explore the data following the link below (data shared under a CC BY 4.0 license). You can browse through all the earthquakes, or find the overview per municipality: doi.org/10.24414/2b5...

With this database, we summarize the seismic impact on Belgium for over a century and computed the maximum intensity for all subcommune levels in Belgiumโฆ

The BTM database currently consists of 23,950 intensity data points (IDPs) on the European Macroseismic Scale for 80 felt earthquakes in and around Belgium, ranging from 2.4 to 5.8 on the local magnitude (ML) scale. The figure gives an overview of the intensity distribution through time

The questionnaires evolved significantly over the 20th century: from small improvised surveys to mass distribution of collective questionnaires sent to local authorities.

In this study we review a century of testimonies how the Belgian population has felt earthquakes in and around Belgium! For every event, communal questionnaires were sent out to the majors of Belgian municipalities. Their replies allowed estimating the intensity of shaking for each commune.

Very proud to announce our new book in Historical Seismology presenting a European - minor Asia earthquake catalogue of the years 284 to 1550! It was an incredible honour to be the editor for this book written by Pierre Alexandre.
