The seismic source parameters (seismic moment, corner frequency, source radius, static stress drop) of the moderate-size earthquakes which occurred in the Vrancea intermediate-depth seismogenic region (Romania) during the last decade are determined using the spectral analysis of S waves. The events have moment magnitudes between 4.5 and 5.7, and depths in the range from 90 to 150 km. The observed data are high-quality horizontal acceleration records. The source parameters are estimated from the displacement amplitude spectrum of the transverse component of motion. The duration of the time windows selected to compute the Fourier spectra is dependent on the earthquake magnitude and amplitude behaviour of the wave trains.The relations between the retrieved source parameters have also been examined. The trend of increasing fault radius with increasing seismic moment is visible, however the slope of the regression line is clearly smaller than the theoretical value predicted by the theory of self-similarity. The tendency of decreasing stress drop with decreasing seismic moment can also be noticed, which might indicate a deviation from the constant stress drop model., The 28th IUGG General Assembly (IUGG2023) (Berlin 2023)

La elaboración de este trabajo se centra en el análisis y la evolución de la normativa sobre la competencia judicial internacional en materia de separación judicial y divorcio. En esta línea, se examina el ámbito de aplicación de los Reglamentos y normativa interna correspondiente, con el objetivo de destacar la confusión generada por la redacción del conjunto de sus artículos. Asimismo, se hace referencia al esfuerzo realizado por las instituciones por reforzar la cooperación jurídica del derecho internacional privado., This proyect focuses on the analysis and evolution of the rules on international jurisdiction on judicial separation and divorce. Therfore, we will examine the application of the Regulations and the appropiate internal regulations, with the aim of highlighting the confusion generated by the drafting of all of its articles. Also, we will refer to the efforts made by the institutions in order to strengthen legal cooperation on private international law., Máster Universitario en Acceso a la Profesión de Abogado (M155)

The seismicity of Romania is significantly affected by earthquakes produced by the Vrancea seismic source with intermediate depth events (3 shocks/century with magnitude Mw greater than 7.0). The seismic activity on the Romanian territory consists of both shallow and intermediate-depth earthquakes. The crustal seismicity is moderate and more scattered in comparison with the intermediate-depth one. The recent upgrade of the seismic network in Romania with high dynamic range accelerometers ( 114 real time seismic stations equipped with episensors) allows recording of moderate to large magnitude earthquakes at very close epicentral distances (less than 10-20 km). Strong motion data of high quality are also of help in increasing the effective preparation against seismic disasters, and the response during seismic emergencies. The consequent increased ability of a community to quickly recover from the damages of an earthquake thus contributes to lower the seismic risk, usually measured in term of casualties and economic losses. During 2016 in this seismic area were recorded two moderate events with 5.7 magnitude in September respectively December. The purpose of this work consists mainly in the estimation of moment magnitude Mw using the strong motion network of the NIEP. A stable and automatic method was developed by Gallo et al.,2014, has been implemented in the real time data acquisition and processing system (ANTELOPE) to estimate in real time the seismic moment, the moment magnitude and the corner frequency of events recorded by accelerometers, using Andrews (1986) method applied to S waves. The main goals are the independent estimation of seismic moment and the common characterization for all events recorded by the strong motion network.
