National borders earthquakes: an attempt at intensity maps unification

Annals of Geophysics, 1994
In this paper the problem of unification of macroseismic maps across national borders is discussed. Up to now some attempts in this way have been carried out, evidencing the difficulties present in such analysis.

Rupture of the 1949 Khait Earthquake on a Cryptic Fault: Implications for Earthquake Hazard

Tectonics, Volume 44, Issue 10, October 2025.
Abstract The 1949 Mw 7.6 Khait earthquake, Tajikistan, was one of the most destructive of the Pamir—Tien Shan region, killing over 7,000 people by building collapse and landsliding. It occurred at the transition between the Pamir and Tien Shan mountain ranges, which converge along the narrow Vashkh river valley.

SPATIAL DISTRIBUTION OF FELT INTENSITIES FOR PORTUGAL EARTHQUAKES [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
Macroseismic intensity is a parameter of the severity of ground movement evaluated in terms of the effects that earthquakes produce on people, buildings and the environment, constituting an extremely important information source for the seismologist and ...

A seismic vulnerability index method for masonry schools in the province of Yazd [PDF]

, 2014
School facilities in Iran, in particular masonry schools, have shown poor performance during past earthquakes and can be identified as the most vulnerable buildings to the earthquakes.

Observational Seismic Fragility Models for Unreinforced Masonry Buildings Based on Building‐by‐Building Damage Data From the 2012 Emilia Earthquakes

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 11, Page 2927-2946, September 2025.
ABSTRACT Over recent decades, Italy has been affected by multiple earthquakes, revealing the significant vulnerability of existing structures. These seismic events have resulted in notable human and economic losses, emphasising the importance of evaluating the impact of one or more seismic events on various building types.

Ground Motion Estimates Updated by Building Damage

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 11, Page 2981-2997, September 2025.
ABSTRACT Classical ShakeMap relies on a conditional Gaussian random field approach to earthquake shaking estimation, where the mean and covariance matrix are derived from a ground motion model, a correlation model for intra‐event residuals, and the recordings from seismic monitoring stations.

Attenuation of Macroseismic Intensity for Crustal Romanian Earthquakes: Calibrating the Bakun-Wentworth’s Method

IOP Conference Series: Earth and Environment, 2019
The purpose of the present study is to elaborate a new model of the macroseismic intensity attenuation using all observed intensities data for the crustal earthquakes in Romania and then, based on this relationship, to calibrate the Bakun-Wentworth ...

Did They Feel It? Legacy Macroseismic Data Illuminates an Engimatic 20th Century Earthquake

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract The challenges and the importance of preserving legacy instrumental records of earthquakes are now well‐recognized (e.g., Richards & Hellweg, 2020, https://doi.org/10.1785/0220200053). Seismologists may not be aware of parallel challenges and opportunities with legacy macroseismic data for earthquakes in the United States. For much of the 20th

Reassessment of the historical seismic activity with major impact on S. Miguel Island (Azores) [PDF]

Natural Hazards and Earth System Sciences, 2003
On account of its tectonic setting, both seismic and volcanic events are frequent in the Azores archipelago. During the historical period earthquakes and seismic swarms of tectonic and/or volcanic origin have struck S.

Developing a global risk engine [PDF]

, 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.
