Is the seismic moment-frequency relation universal? [PDF]
Geophysical Journal International, 2000 SUMMARY We evaluate the seismic moment‐frequency relation for the Harvard catalogue in the period 1977‐1994. This catalogue is composed of about 12 000 earthquakes. After selection of events in terms of depth and energy, we retain about 8000 data points.

Match Compliance of Conventional Design Codes with Instructions for Seismic Rehabilitation of Buildings in Performance Evaluation of Steel Moment Frames [PDF]
Journal of Structural and Construction Engineering, 2019 Today, instructions for seismic rehabilitation of existing buildings are widely used for seismic performance evaluation of existing buildings. Moreover, nonlinear structural analysis methods are permitted for seismic design of new buildings in recent ...

Buildings, 2023 The Soil–Structure Interaction (SSI) effect has been widely evidenced during several earthquakes around the world. In the Venezuelan context, the seismic event in Caracas in 1967 showed the significant consequences of designing buildings without ...

Energy Reports, 2020 The safety of a nuclear power plant against earthquakes can be improved by installing seismic isolation devices. As such seismic isolation devices handle seismic loads, however, displacements larger than those generated before the application of such ...

Seismic Moment Evolution During Hydraulic Stimulations [PDF]
Geophysical Research Letters, 2020 AbstractAnalysis of past and present stimulation projects reveals that the temporal evolution and growth of maximum observed moment magnitudes may be linked directly to the injected fluid volume and hydraulic energy. Overall evolution of seismic moment seems independent of the tectonic stress regime and is most likely governed by reservoir specific ...

Consistency between a strain rate model and the ESHM20 earthquake rate forecast in Europe: insights for seismic hazard [PDF]
Natural Hazards and Earth System SciencesThis work aims at investigating the consistency between a strain rate model and a long-term earthquake forecast at the European scale. We take advantage of the release of geodetic strain rate models by Piña-Valdés et al.

Annals of Geophysics, 1997 We analyzed the distribution of seismic moment in Italy, computed from instrumental seismicity recorded by the Italian National Seismic Network in the past 14 years, to map the areas where seismic deformation processes have been active in this time ...

Seismic moment distribution [PDF]
Geophysical Journal International, 1991 SUMMARY We review possible errors in determining the size of earthquakes. We propose that the size distribution can be effectively defined only for earthquake sequences, not for ‘individual’ earthquakes. As a result of the error analysis, we question the validity of many reported correlations between the 6-value and spatio-temporal characteristics of ...

The first-order statistical moment of the seismic moment tensor [PDF]
Geophysical Journal International, 1985 Summary. If a complex earthquake is assumed to be a set of individual, randomly oriented elementary pure double couple sources, the solution for the seismic moment of the complex event projected on the mean trend of the fault will perforce be comprised of sources of both double couple and compensated linear vector dipole (CLVD) types.
