Fragility‐based seismic assessment of traditional masonry buildings on Azores (Portugal) using simulated ground‐motion records

open access: yesEarthquake Spectra, Volume 40, Issue 4, Page 2836-2861, November 2024.
Traditional unreinforced masonry structures are extremely vulnerable to seismic events, featuring large losses in many countries worldwide. This study focuses on the seismic assessment of a traditional masonry structures located in Faial Island—Azores (Portugal), which was hit by an earthquake of Mw = 6.2 on 9 July 1998. A set of analyses was conducted

An analytic method for separating local from regional effects on macroseismic intensity

open access: yesAnnals of Geophysics, 1995
nterpretation of macroseismic data is hazardous, due to its qualitative nature. This, linked with errors in eval- uation,) and the variations of local intensity, makes it difficult to draw valid conclusions.

Developing a global risk engine [PDF]

open access: yes, 2010
Risk analysis is a critical link in the reduction of casualties and damages due to earthquakes. Recognition of this relation has led to a rapid rise in demand for accurate, reliable and flexible risk assessment software.

An extreme wave event in Timanfaya National Park: Possible first geological evidence of the 1755 Lisbon tsunami in Lanzarote, Canary Islands

open access: yesEarth Surface Processes and Landforms, Volume 49, Issue 13, Page 4133-4153, October 2024.
Two extreme wave event deposits of boulders have been located on a coastal platform formed by lavas from the 1730‐36 Timanfaya eruption in Lanzarote Island. The modelling of wave heights and tsunami heights required to mobilise these blocks shows that a tsunami was necessary to accumulate the boulders into ridges.

The French macroseismic database SISFRANCE: objectives, resultsand perspectives

open access: yesAnnals of Geophysics, 2004
To comply with nuclear safety requirements, an in-depth research program for the revision of existing catalogues was initiated back in 1974. The priority of the partners involved in the SISFRANCE project was to establish the most exhaustive documentary ...

Testing and Developing the Macroseismic Intensity Attenuation Relationships for the Vrancea (Romania) Crustal Earthquakes

open access: yesIOP Conference Series: Earth and Environment, 2019
A correct seismic hazard assessment and intensity-based shake maps of a seismic zone depend on the determination of parameters that emphasize the distribution and the macroseismic intensity attenuation for that seismogenic zone. Due to the reduced number

Investigating the Last Millennium Coulomb Stress Transfer in the Central Apennine Fault System (CAFS)

open access: yesTectonics, Volume 43, Issue 10, October 2024.
Abstract The Central Apennine Fault System (CAFS) characterizes an active tectonic region of significant importance, witnessing numerous destructive seismic events over the last millennia. Although numerous studies have underscored the role of Coulomb stress transfer (CST) in initiating some of the most catastrophic earthquakes, investigations focusing

Assessing the Reliability of Earthquake Environmental Effects in Historical Events: Insights from the Southern Apennines, Italy

open access: yesGeosciences, 2020
Earthquake Environmental Effects (EEEs) are a common occurrence following moderate to strong seismic events. EEEs are described in literary sources even for earthquakes that occurred hundreds of years ago, but their potential for hazard assessment is not

Active Fault Interaction in the Eastern Betic Cordillera: A Model of Coseismic and Postseismic Stress Transfer Following Historical Earthquakes in SE Spain

open access: yesTectonics, Volume 43, Issue 10, October 2024.
Abstract The Spanish historical earthquake catalog reveals a significant number of destructive earthquakes (≥ ${\ge} $Mw 6.0) that have occurred along the Eastern Betic Shear Zone (EBSZ), a major active fault system at the Eastern Betic Cordillera. However, during the last century, seismic activity in this region has been characterized by the absence ...
