A real-time prediction model for macroseismic intensity in China [PDF]
Journal of Seismology, 2020 The macroseismic intensity spatial distribution is an important input for most rapid loss modeling and emergency work. Data from a total of 175 earthquakes ( M s ≥ 5.0) in China from 1966 to 2014 were collected, and the rapid assessment method of ...

Geophysical Journal International, 2022 We derived new, reversible relationships between macroseismic intensity (I), expressed in either the European Macroseismic (EMS-98) or the Mercalli-Cancani-Sieberg (MCS) scales, and peak ground acceleration (PGA), peak ground velocity (PGV) and the ...

Procedure to estimate maximum ground acceleration from macroseismic intensity rating: application to the Lima, Perú data from the October-3-1974-8.1-Mw earthquake [PDF]
Advances in Geosciences, 2008 Post-disaster reconstruction management of urban areas requires timely information on the ground response microzonation to strong levels of ground shaking to minimize the rebuilt-environment vulnerability to future earthquakes. In this paper, a procedure

Inhomogeneity of Macroseismic Intensities in Italy and Consequences for Macroseismic Magnitude Estimation [PDF]
Seismological Research Letters, 2021 AbstractWe show that macroseismic intensities assessed in Italy in the last decade are not homogeneous with those of the previous periods. This is partly related to the recent adoption of the European Macroseismic Scale (EMS) in place of the Mercalli–Cancani–Sieberg (MCS) scale used up to about one decade ago. The underestimation of EMS with respect to

USGS “Did You Feel It?” Internet-based macroseismic intensity maps
Annals of Geophysics, 2011 The U.S. Geological Survey (USGS) “Did You Feel It?” (DYFI) system is an automated approach for rapidly collecting macroseismic intensity data from Internet users’ shaking and damage reports and generating intensity maps immediately following earthquakes;

Visualization of macroseismic parameters during examination of epicentral zones of strong earthquakes [PDF]
E3S Web of Conferences, 2021 The article discusses the fragile destruction of building materials during strong earthquakes, the features of the macroseismic effect of cracking expressed in the protective coatings of buildings; it is recommended to optimize the composition based on ...

Macroseismic intensity attenuation equations for Central Asia earthquakes [PDF]
IOP Conference Series: Earth and Environmental Science, 2021 Abstract Based on macroseismic survey data for strong earthquakes in Central Asia, the coefficients of attenuation of seismic intensities with distance in the Blake-Shebalin- and Kovesligethy -type equations were refined. A new generalized dependence of macroseismic intensity attenuation on distance, taking into account the depth of the ...

1921–2021: 100 years of macroseismic studies at BCSF
Comptes Rendus. Géoscience, 2021 The French Central Seismological Bureau (BCSF) was set up in Strasbourg in July 1921 by a governmental decision. Since then, BCSF is in charge of the macroseismic survey for the French territories.
