Shear Strengthening of Stone Masonry Walls Using Textile-Reinforced Sarooj Mortar

Buildings
Most historical buildings and structures in Oman were built using unreinforced stone masonry. These structures have deteriorated due to the aging of materials, environmental degradation, and lack of maintenance.

2025 U.S. Geological Survey National Seismic Hazard Model for Puerto Rico and the U.S. Virgin Islands: Overview of Model and Hazard Results

Earthquake Spectra, Volume 42, Issue 2, May 2026.
The U.S. Geological Survey recently updated the National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). The first version of the PRVI NSHM was released in 2003, and therefore this 2025 update includes over 20 years of new geologic, geophysical, and engineering data, methods, and models.

From Warnings to Actions: Factors Influencing Response to Earthquake Early Warning—A Systematic Literature Review

Earthquake Spectra, Volume 42, Issue 2, May 2026.
Earthquake early warning (EEW) systems offer critical seconds for protective actions, yet their effectiveness ultimately depends on human interpretation and response. This article presents a systematic literature review of factors shaping public behavior during earthquakes and in response to EEW alerts.

DYNAMIC RESPONSE OF VENTILATED MASONRY FAÇADES WITH INTEGRATED RETENTION SYSTEMS

ce/papers, Volume 9, Issue 1, Page 145-150, April 2026.
Abstract An effective strategy to mitigate seismic risk and enable the use of ventilated façades in seismic regions, while taking advantage of their high energy efficiency, consists of implementing retention or containment systems that prevent the detachment and fall of façade components during a seismic event.

Seismic Enhancement of Masonry‐Infilled Substandard Reinforced Concrete Frames Using Lightweight Steel Exoskeleton

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 603-623, March 2026.
ABSTRACT A significant portion of existing reinforced concrete (RC) structures in seismically active regions was constructed prior to the adoption of modern seismic design standards, leaving them highly susceptible to earthquake‐induced damage. The vulnerabilities of these structures, often exacerbated by material degradation, have been starkly ...

Evaluating the Seismic Damage Dynamics of Buildings’ Vertical Growth in Lima, Peru

Earthquake Spectra, Volume 42, Issue 1, February 2026.
In Lima, as in many cities, most residential buildings grow vertically over their lifespan due to incremental construction. Multiple stories are added to buildings, often without structural retrofits or even without design. As a result, the seismic vulnerability of these buildings increases, requiring the government to create resilience policies that ...

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 ...
