Large earthquakes within stable continental regions (SCR) show that significant amounts of elastic strain can be released on geological structures far from plate boundary faults, where the vast majority of the Earth’s seismic activity takes place. SCR earthquakes show spatial and temporal patterns that differ from those at plate boundaries and occur in regions where tectonic loading rates are...

Reliable seismic hazard analysis is based on good quality data and models of the distribution of earthquakes in terms of time, space and size and the underlying processes that can explain this distribution. To improve the basis in Germany present work coordinated by BGR focuses on the earthquake catalogue, the paleoseismological database, the database of active faults and a seismotectonic...

There is a wide consensus on the magnitude, Ms5.4, of the Fennoscandian earthquake on 23 October 1904, which makes it the largest onshore/nearshore event in the region during the 1900s. In much of the available literature it is known as the Oslofjord earthquake. An earthquake of this magnitude is rare in the Fennoscandian Shield, so it is meaningful to extract all possible information about...

The 2018 seismic sequence of Mayotte began the 10 May at 50-60 km east from the island and Mamoudzou (most important city of Mayotte with approximately 70000 inhabitants) with earthquakes of magnitude 3 – 4. The major event with a magnitude of 5.7 (BRGM) took place 5 days after (Mw 5,8-5,9 USGS), preceded the day before by a magnitude 5.2. Until the 15 June (period considered in the study of...

Magnitude estimates of earthquakes occurred before the instrumental period are a key issue in seismic hazard assessment. For such earthquakes, the only information available is provided by historical sources. These are first translated into macroseismic intensity by means of intensity scales and then intensities are used to estimate earthquake parameters such as epicentral intensity, magnitude...

Different geo-hazards are investigated in the framework of the German-Bangladesh technical cooperation project: “Geo Information for Urban Planning and Adaptation to Climate Change (GPAC)". Seismic hazard assessment is one focus of the project. Bangladesh is located close to the boundaries of the complex convergence of Indian and Eurasian plates to the north and to the east. These collision...

The seismicity of Eastern Europe before the 15th century is not well known because historical sour¬ces (annals, chronicles, etc.) are missing, except in Russia. Numerous claimed earthquakes in traditional com¬pilations were demonstrated as late forgeries in the study of Pierre and Dominique Alexandre (2012).
The first well known general shock is the one of June 5th, 1443. The former work...
