Review article: Review of fragility analyses for major building types in China with new implications for intensity–PGA relation development [PDF]

Natural Hazards and Earth System Sciences, 2020
The evaluation of the seismic fragility of buildings is one key task of earthquake safety and loss assessment. Many research reports and papers have been published over the past 4 decades that deal with the vulnerability of buildings to ground motion ...

Validation of ShakeMaps Created From Global Navigation Satellite System (GNSS) Velocities

Earthquake Spectra, Volume 42, Issue 3, August 2026.
Ground velocity observations generated through a time difference of Global Navigation Satellite Systems (GNSS) phase observables and orbits have been shown to be comparable to seismic recordings without clipping during intense ground motions. Computing GNSS velocities is also computationally scalable and increases the density of ground motion ...

New Constraints on Active Normal Faulting in the South Gulf of Evia, Greece: Geometry, Evolution, and Seismic Hazard of the South Coastal Fault System

Tectonics, Volume 45, Issue 7, July 2026.
Abstract In many areas of active faulting, the continuity of normal faults with short or incomplete historical earthquake records and more subdued topographic expressions is not fully understood and consequently the seismic potential of these faults is often underestimated.

A Deep Learning Framework for Peak Ground Velocity Prediction Using Multi‐Station Velocity Waveforms: The Taiwan Transformer Shaking Alert Model (TT‐SAM)

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract This study proposes a deep‐learning–based regional earthquake early warning model, the Taiwan Transformer Shaking Alert Model (TT‐SAM). The model adopts peak ground velocity (PGV) as its primary ground shaking prediction unit, aiming to better reflect actual structural damage and thereby enhance the practical utility and accuracy of the ...

Intensity assignments from historical earthquake data: issues of certainty and quality

Annals of Geophysics, 1998
The use of macroseismic data in assessing parameters for historical earthquakes for use in seismic hazard assessment has thrown more attention on the way in which these data are treated.

USGS “Did You Feel It?”—Science and Lessons From 20 Years of Citizen Science-Based Macroseismology

Frontiers in Earth Science, 2020
The U.S. Geological Survey (USGS) “Did You Feel It?” (DYFI) system is an automatic method for rapidly collecting macroseismic intensity (MI) data from internet users’ shaking and damage reports and for generating intensity maps immediately following felt

Source Parameters of the 1906 Manas (Mw 7.7), 1944 Xinyuan (Mw 7.2) and 1812 Nilke Earthquakes and Seismotectonics of the Borohoro Shan, Western China

Tectonics, Volume 45, Issue 6, June 2026.
Abstract The 1906 Manas Earthquake is the largest earthquake recorded in the Borohoro Shan (BRS) since 1900. The reported magnitude ranges from 7.2 to 8.3, but uncertainties remain regarding its size, mechanism, and responsible fault. Similar confusion exists for the 1812 Nilke and 1944 Xinyuan Earthquakes, the only other Mw > 7 earthquakes in the NE ...

Integrating strong-motion recordings and twitter data for a rapid shakemap of macroseismic intensity

, 2020
Rapid estimation of the intensity of seismic ground motions is crucial for an effective rapid response when an earthquake occurs. To this end, maps of updated grond-motion fields (or shakemaps) are produced by using observations or measurements in near ...

In for a penny: An empirical study of earthquake experience and non‐pharmaceutical intervention effectiveness in the Marche region

Annals of Public and Cooperative Economics, Volume 97, Issue 2, Page 469-501, June 2026.
Abstract This study investigates whether prior exposure to natural disasters influenced individual compliance with non‐pharmaceutical interventions (NPIs), specifically lockdown measures, during the Corona Virus Infectious Disease 2019 (COVID‐19) pandemic. Focusing on the Marche region of Italy, which experienced a severe earthquake in 2016, we exploit
