Abstract: The seismicity of Scandinavia is low to intermediate in intensity and with magnitudes that rarely exceed 5.5. Even so, the characterized by a great diversity space time, related fact its driving forces, or sources stress, are multiple also diverse nature. dominant forces range from plate-related (such as ridge push) through regional local ones topography); all, however, somehow lateral inhomogeneities lithospheric structure. Whereas it was earlier assumed post-glacial uplift main...
A new evaluation of seismic hazard in Central America has been carried out as part the cooperation project named RESIS II under auspices Norway Cooperation Agency (NORAD). Several seismic‐hazard experts from Costa Rica, Guatemala, Honduras, Nicaragua, El Salvador, Panama, Norway, and Spain participated study, which was aimed at obtaining results suitable for design purposes. The analysis started with a thorough revision national catalogs catalog compiled homogenized to moment magnitude, M w....
We investigate the influence of glacial isostatic adjustment (GIA) on deformation at surface and seismogenic depths in Fennoscandia. The strain rate field, derived from geodetic data, is controlled by GIA which causes NW–SE extension up to 4 × 10−9 yr−1 most mainland Fennoscandia, surrounded regions radial shortening towards centre uplift. seismic a new compilation focal mechanisms, shows consistent compression Norwegian continental margin tendency tension moment least two orders magnitude...

Abstract We document a complete seismic hazard study for mainland Norway and the Svalbard archipelago. The is based on Probabilistic Seismic Hazard Analysis (PSHA) method, first time new earthquake catalogue presented publicly that covers Norway, adjacent offshore regions. developed from an extensive analysis of historical earthquakes combined with more recent instrumental data 33,864 reports between 1497 through 2018, magnitudes up to Mw 6.7. With this computed 10% exceedance in 475 years...
Abstract Recent stress observations from in situ measurements and earthquake focal mechanisms the Norwegian onshore offshore areas are evaluated with aim of characterizing most important for present field around Norway. The evaluation is based on a set indicators that include both shallow (overcoring borehole breakouts) deep data (earthquake mechanisms). Computer simulations simple stress-generation models were used to constrain relative importance different stress-generating mechanisms....
Abstract. The primary background for the present study was a project to assist authorities in Thailand with development of plans how deal future tsunami risk both short and long term perspectives, wake devastating 26 December 2004 Sumatra-Andaman earthquake tsunami. is focussed on defining analyzing number possible scenarios (magnitudes 8.5, 8.0 7.5) associated return periods, each one accompanied by specific modelling. Along most affected part western coast Thailand, wave caused maximum...
A damage estimation exercise has been carried out using the building stock inventory and population database of Istanbul Metropolitan Municipality selected European earthquake loss packages: KOERILOSS, SELENA, ESCENARIS, SIGE, DBELA. The input ground-motions, common to all models, correspond a "credible worst case scenario" involving rupture four segments Main Marmara Fault closest in Mw 7.5 earthquake. aim is assess applicability software packages context rapid post-earthquake response...
Abstract A database of 109 earthquake focal mechanisms for Scandinavia and Svalbard has been compiled, comprising 29 new solutions. Stress directions extracted from these have calculated southeastern southwestern Norway, the Norwegian Sea Barents-Finnmark region. The principal horizontal stress is c. N45°W, indicates a clockwise rotation as one moves south to north, in accordance with trajectories that can be expected ridge push. data indicate southern Norway normal faulting regimes are more...
A comprehensive compilation of 112 earthquake focal mechanism solutions in Norway and adjacent areas has been completed, including 7 previously unpublished for recent earthquakes determined as part the NEONOR (Neotectonics Norway) project. Using method Gephart & Forsyth (1984), 97 on Norwegian mainland margin have inverted with respect to primary stress directions, which a regional basis best possible way could satisfy individual solutions. In doing this were divided into six zones...
A seismic risk assessment methodology based on socioeconomic clustering of urban habitat is presented in this paper. In methodology, the city divided into different housing clusters level occupants, representing reasonably uniform risk. It makes an efficient utilization high resolution satellite data and stratified random sample survey to develop building stock database. Ten classes found Indian cities are defined 34 model types (MBTs) prevalent subcontinent have been identified compared...
A comprehensive data base of about 17000 historical and recent earthquakes has been established for the Central American region, based on existing research reports from Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica Panama. The catalog includes known damaging historic earthquakes, as well more important data, including both macroseismic instrumental observations. starts in beginning 16th century is limited to (reeported phenomena associated damage) until 1902, while it time since...
