The damaging 1932 Uden Earthquake in the Netherlands – revision of cross‑border macroseismic data and its impact on source parameters
No full textA re-assessment of the macroseismic intensity data was conducted for the second-largest instrumentally recorded event in the Netherlands: the 20 November 1932 Uden earthquake. This event was felt across the Netherlands, Belgium and Germany. Intensity values on the EMS98 scale were assigned based on original data (reports/enquiries/letters), manually for the Netherlands and automatically for Belgium, with existing German data added for completeness. The updated dataset was used to calculate macroseismic location and magnitude using the Bakun and Wentworth (1997, 1999) algorithm. To capture epistemic uncertainty, four newly calibrated intensity attenuation relations were applied and their results averaged. The results using only intensity data from the Netherlands provided stable solutions within the region of maximum observed intensity ( Imax = VII). However, including Belgian and German data shifted the source location outside this region and becomes less reliable, likely due to differences in data collection methods and local/regional site effects. Comparison of confidence levels from the BW method with bootstrap modelling showed that almost all bootstrap results fall within the 50% confidence region. A more realistic estimate for the location uncertainty was derived from the bootstrap analysis. The revised source parameters are 51.63°N and 5.61°E ± 7.3 km for the source location and ML = 5.1 ± 0.3 ( MS 4.9 ± 0.3) for the magnitude
Flood preparedness in The Netherlands: A US perspective
No full textWe claim that, in The Netherlands, emergency management for flooding should be seen as an \u91add on\u92 to existing emergency planning. Therefore, some specific preparation is required to minimize loss of life and maximize the use of available information, resources and infrastructure. This booklet discusses this preparation based on the experiences of the NUWCReN network within the context of The Netherlands and other countries with limited budgets for flood preparedness and low risk perception of the public and limited urgency for preparation by decision makers
Luminescence dating of Netherlands’ sediments
No full textOver the last decades luminescence dating techniques have been developed that allow earth scientists to determine the time of deposition of sediments. In this contribution we review: 1) the development of the methodology; 2) tests of the reliability of luminescence dating on Netherlands’ sediments; and 3) geological applications of the method in the Netherlands. Our review shows that optically stimulated luminescence dating of quartz grains using the single aliquot regenerative dose method yields results in agreement with independent age control for deposits ranging in age from a few years up to 125 ka. Optical dating of quartz has successfully been applied to sediments from a wide range of depositional environments such as coastal dunes, cover sands, fluvial channel deposits, colluvial deposits and fimic soils. These results demonstrate that optical dating is a powerful tool to explore the natural archive of the Netherlands’ subsurface.Civil Engineering and Geoscience
