Do seismologists agree upon epicentre determination from macroseismic data? A survey of ESC Working Group ' Macroseismology'

open access: yesAnnals of Geophysics, 1996
In contrast to the case of instrumental data, the procedures for epicentral parameter determination (coordinates and I0) from macroseismic data are not very well established. Although there are some "rules", upon which most seismologists agree (centre of

Comparison of vulnerabilities in typical bridges using macroseismic intensity scales

open access: yesCase Studies in Construction Materials, 2022
The macroseismic intensity scale in different regions is extensively assessed in the vulnerability assessment of building structures and is rarely used to quantify the damage characteristics of group bridges. To more accurately examine the differences in

Seismicity and Seismotectonics in the Cantabrian‐Pyrenean Zone (N Spain) Using a Dense Temporary Network of Broadband Seismic Stations

open access: yesTectonics, Volume 45, Issue 3, March 2026.
Abstract Earthquakes in intraplate regions are often scattered and difficult to associate with specific geological structures, requiring detailed surveys to identify active faults. Improving knowledge of local seismicity in these areas is essential for accurate seismic hazard assessment and for safe planning of economic activities that could affect ...

National‐scale Mapping of the Expected Earthquake Magnitude for Soil Liquefaction Triggering Analyses in Italy

open access: yesEarthquake Spectra, Volume 42, Issue 1, February 2026.
This paper introduces a procedure to estimate moment magnitude (MW) in earthquake‐induced soil liquefaction probabilistic risk assessment. The method is based on using the historical seismicity modelled with a truncated Gutenberg‐Richter (G‐R) relation, jointly with an empirical model linking the MW to the maximum source‐to‐site distance at which soil ...

National borders earthquakes: an attempt at intensity maps unification

open access: yesAnnals 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.

Beyond Deaths and Dollars: Modeling Requirements to Support Equity‐Focused Disaster Risk Management

open access: yesEarthquake Spectra, Volume 42, Issue 1, February 2026.
The disaster risk modeling framework has long focused on quantifiable impact metrics to assess a hazard's potential direct effects, such as fatalities (deaths) and economic losses (dollars). Over time, as the framework has expanded to inform both public and private applications, additional impact metrics that more directly consider the societal roots ...

Revised History of Pleistocene Vertical Motions in NE Sicily and Southern Calabria, Italy, From 40Ar/39Ar Dating and Fault Zone Morphology

open access: yesTectonics, Volume 45, Issue 2, February 2026.
Abstract Long‐term rates of crustal uplift in southern Calabria and NE Sicily are incompletely understood due to limited information about the age of marine terraces at 1.0–1.3 km above sea level (asl). This study provides a new constraint on high‐elevation terrace ages through integrated analysis of geochronology, stratigraphy, shoreline modeling, and

Attenuating intensities

open access: yesAnnals of Geophysics, 1996
The study presents a methodology in which fractile distances for a given macroseismic intensity are used as a point measure on which to do attenuation characterization.

SPATIAL DISTRIBUTION OF FELT INTENSITIES FOR PORTUGAL EARTHQUAKES [PDF]

open access: yesThe 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 ...
