The 2025 Puerto Rico and Virgin Islands U.S. National Seismic Hazard Model Update: Ground Motion Model Selection and Comparison

Earthquake Spectra, Volume 42, Issue 2, May 2026.
We evaluate, select, and describe the ground‐motion models (GMMs) used in the 2025 update of the U.S. National Seismic Hazard Model (NSHM) for Puerto Rico and the U.S. Virgin Islands (PRVI). We identify the most appropriate models that align with GMM selection criteria for use in the PRVI region to improve the accuracy of seismic hazard assessments ...

Investigation of Subsurface Characteristics by using a Vs30 Parameter and a Combination of the Hvsr and Spac Methods for Microtremor Arrays

International Journal of Technology, 2017
Palu City is an active seismic area in Indonesia due to the very active Palu-Koro fault system. The development of the city area, therefore, must consider the risks induced by the seismic activities. The risk assessment has to be supported by information

IDENTIFIKASI ZONA POTENSI LIKUIFAKSI DI KOTA BANDAR LAMPUNG BERDASARKAN ANALISIS DATA SPASIAL

JGE
Likuifaksi terjadi ketika tanah yang jenuh air kehilangan kekuatannya akibat pergerakan tanah yang disebabkan oleh gempabumi. Keberadaan sesar-sesar aktif di daerah penelitian meningkatkan risiko aktivitas gempabumi yang dapat memicu likuifaksi.

Comparison of site classification from VS30, VS10, and HVSR in Italy

, 2009
The aim of this work is to verify if (1) the average of shear-wave velocity from the surface to 30 m depth (VS30) is a good proxy of site amplification in a country with complex geology like Italy, (2) the grouping of VS30 in different soil classes and ...
