Inferring the depth and magnitude of pre-instrumental earthquakes from intensity attenuation curves [PDF]

Natural Hazards and Earth System Sciences, 2023
The Italian historical earthquake record is among the richest worldwide; as such it allows for the development of advanced techniques for retrieving quantitative information by calibration with recent earthquakes.

Nuove evidenze di correlazione tra l'attenuazione macrosismica ed i campi di lineamenti strutturali nell'Italia meridionale

Annals of Geophysics, 1982
The analysis of a large number of macroseismic fields of past and recent<br />earthquakes in Southern Italy allows a wider check of a previous interpretative<br />model of the anisotropy of the regional macroseismic field, in the context of a

28 March 2025 Myanmar Earthquake: Strong Ground Motions, Macroseismic Intensity, Liquefaction, and ALOS-2 ScanSAR Remote Sensing Damage Observations

Seismological Research Letters
On 28 March 2025, a devastating M 7.7 earthquake struck Myanmar along the right-lateral strike-slip Sagaing fault, followed by an M 6.7 aftershock twelve minutes later.

From historical earthquake records to intensity value: some results of a study

Annals of Geophysics, 1995
The use of historical records to assess macroseismic intensity involves problems seldom evidenced. This paper deals with the problems connected with the use of macroseismic scales, with particular attention to MSK 81 and the EMS 92, in the case of two ...

New relationships between macroseismic intensity and local magnitude for the volcanic region of Mt. Etna (Italy)

Journal of Seismology
The volcanic region of Mt. Etna (Italy) has a well-documented historical seismic activity, with records of seismic and volcanic events on the volcano dating back to late 1633.

Support Vector Regression for the Relationships between Ground Motion Parameters and Macroseismic Intensity in the Sichuan–Yunnan Region

Applied Sciences, 2020
In this paper, a nonlinear regression method called a support vector regression (SVR) is presented to establish the relationship between engineering ground motion parameters and macroseismic intensity (MSI).

Critical considerations on the evaluation of macroseismic effects

Annals of Geophysics, 1980
The definition of some of the standards used for evaluating local effects<br />and optimizing the relative macroseismic procedures are critically<br />considered, also from the different interpretative points of view to have<br />come ...

Constraining earthquake fault sources through the use of intensity data and seismic scenarios: application to the Betic Cordillera (South Spain)

Frontiers in Earth Science, 2023
Macroseismic observations can be useful to study pre-instrumental earthquakes when paleoseismological analysis are not viable for various reasons (e.g., erosion or lack of sedimentation).

Validation of Peak Ground Velocities Recorded on Very-high rate GNSS Against NGA-West2 Ground Motion Models

Seismica, 2023
Observations of strong ground motion during large earthquakes are generally made with strong-motion accelerometers. These observations have a critical role in early warning systems, seismic engineering, source physics studies, basin and site ...
