We report on a pilot demonstration of the usefulness of analog seismograms to improve the database of ocean storms before the 1980s by providing additional data for the quantitative validation of ocean wave modeling, in particular for extreme events. We present a method for automatic digitization of paper seismograms to extract microseismic ground-...

Owing to the implantation of the « Princess Elisabeth » polar base in East-Antarctica, the Royal Observatory of Belgium undertook research in seismology by installing in February 2010 a permanent broadband seismic station on the bedrock near the base. Due to the poor coverage of permanent seismic stations in Antarctica and the small number build on...

Spécial tremblement de Terre de Liège du 8 novembre 1983: trente ans après: le réseau belge de surveillance sismique depuis 1985.

The Royal Observatory of Belgium (ROB) is responsible for the seismic activity monitoring in Belgium. For this purpose the ROB operates a network of 24 seismic stations. In addition 18 accelerographs have been installed since 2001 in the most seismic active zones. Seismometers allow detecting and localizing any earthquake of magnitude larger than 1...

Paper (in French) describing the effects of the Ms = 4.6 of the July 22, 2002 Alsdorf (DE) earthquake. It reports on the first accelerometric measurements and te first "DYFI" macroseismic enquiry performed in Belgium.

The recordings of quarry blasts in the South of the Brabant Massif and in the East of Belgium allowed us to retrieve the vertical distribution of the P-waves velocity in the upper crust and lateral inhomogeneities in the velocity distribution. The results show large differences between the two regions under study, which can be explained, by structu...
