Spectrum-compatible accelerograms with harmonic wavelets

Computers & Structures, 2015
AbstractModern building codes allow the analysis and design of earthquake-resistant structures with recorded and/or generated accelerograms, provided that they are compatible with the elastic design spectrum. The problem then arises to generate spectrum-compliant accelerograms with realistic non-stationary characteristics, which in turn may play an ...

Predicting Seismic Debris Distributions of Collapsed Unreinforced Masonry Structures Through Physics Engines and Machine Learning Algorithms

Earthquake Spectra, Volume 42, Issue 1, February 2026.
Unreinforced masonry (URM) structures are widespread worldwide, particularly in older urban districts. However, URM buildings—particularly those constructed before the introduction of modern building codes—are highly vulnerable to seismic hazard, and prone to experiencing local and/or global failures when subjected to significant horizontal shaking ...

Spectral analysis of Al Haouz earthquake and comparison with the design spectrum [PDF]

E3S Web of Conferences
Al Haouz earthquake damage highlights the insufficiency of the current normative spectrum. Spectral amplitude comparison against the local records shows that the spectral amplitudes, in certain periods ranges, were greater than RPS 2011 predictions ...

Supershear Transitions and Bilateral Asymmetric Rupture of the 2025 Sagaing (Myanmar) Earthquake Revealed by Geodetic and Seismic Observations

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Sagaing Fault (SF) accommodates major plate motion in Myanmar, yet large earthquakes along it have rarely been captured by modern geodetic and seismic observations. The 2025 Sagaing earthquake generated an exceptionally long rupture (∼535 km), offering a rare opportunity to investigate rupture dynamics along continental transform fault. We

Optical Instrument Survival In A Major Earthquake [PDF]

, 1980
Many organizations presently are evaluating the potential loss to plant, equipment and production capability in event of a major earthquake in their area. Often it is found that equipment can be protected at a fraction of the replacement cost.

Geological and Historical‐Based Approaches to Define Scenario Earthquake: Case‐Studies and Application at Municipality‐Scale in Italy

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 15, Page 3828-3845, December 2025.
ABSTRACT This study compares two approaches for determining earthquake magnitude (M) and source‐to‐site distance (R) to assess seismic scenarios in Italy. The first method relies on geological criteria from the Italian seismogenic sources database (DISS3.3.0), while the second method uses historical earthquakes from the DBMI‐CPTI15 Italian catalogue ...

A non-separable stochastic model for pulse-like ground motions [PDF]

, 2013
A phenomenological non-separable non-stationary stochastic model is proposed to represent near-fault pulse-like ground motions (PLGMs) by means of a parametrically defined evolutionary power spectrum (EPSD). Numerical data pertaining to ensembles of EPSD

Earthquake Accelerogram Selection and Scaling Procedures for Estimating the Distribution of Drift Response

, 2011
The problem of selecting a suite of earthquake accelerograms for time-domain analyses is of particular practical and academic interest. Research in this field has led to numerous approaches for compiling suites of accelerograms that may be used to ...

Near‐Fault Strong‐Motion of the 2023 Mw7.8 Kahramanmaraş Earthquake: Insights Into High‐Frequency Radiation Mechanisms

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract While classic double‐couple earthquake models explain seismic wavefields accurately at low frequencies, at higher frequencies, seismic radiation exhibits significantly more complex and stochastic characteristics. Various on‐fault and off‐fault mechanisms have been proposed to explain high‐frequency radiation, yet their relative contributions ...
