Analysis of the Guatemalan earthquake catalog
Journal of SeismologyAbstract In this paper, we study the geographic and temporal distribution of earthquakes in Guatemala, and their magnitudes, from 1526 to October 2022. We utilized the earthquake catalog of the national seismic network of Guatemala, complemented by two additional sources. First, we describe the development of the detection network and

Post-earthquake assessment of moderately damaged reinforced concrete plastic hinges
, 2020 Modern reinforced concrete buildings are often designed to dissipate energy during strong earthquakes by permitting the controlled formation of plastic hinges. Plastic hinges require assessment of residual capacity in post-earthquake situations. However,

Pervasive Foreshock Activity Across Southern California
Geophysical Research Letters, 2019 Foreshocks have been documented as preceding less than half of all mainshock earthquakes. These observations are difficult to reconcile with laboratory earthquake experiments and theoretical models of earthquake nucleation, which both suggest that ...

Deep Underground Science and Engineering, EarlyView.The fused data extracted from the distributed monitoring system as the data basis, combined with dynamic geological data, are imported into a deep learning model. As the geological conditions of mining and excavation change, the risk of water inrush at the working face is retrieved in real time.

Complex Versus Parsimonious Site‐Based Stochastic Ground Motion Models: Which One Is Better?
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Stochastic ground motion models (GMMs) provide a probabilistic representation of seismic input and are increasingly important for uncertainty quantification (UQ) in earthquake engineering. This study focuses on site‐based stochastic GMMs, which learn the statistical features of selected datasets of seismic records and generate statistically ...

Accuracy of modern global earthquake catalogs
Physics of the Earth and Planetary Interiors, 2003 We compare several modem (1977-present) worldwide earthquake catalogs to infer their completeness, earthquake origin time and hypocenter location accuracy, magnitude/scalar seismic moment errors, and difference between individual focal mechanism/moment tensor solutions.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT In current dynamic time history assessment protocols, ground motion recordings are mostly oriented along fixed sensor directions. Consequently, the orientation of the principal resultant of rupture energy, which may control the maximum structural demand, remains undefined, precluding consistent correlation with physically detrimental ...
