Analysis of Earthquake Risk Zones Using the Horizontal to Vertical Spectral Ratio (HVSR) Method at Vital Objects of Radin Inten II Airport, Natar Market, and Branti Market

South Lampung, Indonesia, lies within the tectonically active Indo-Australian–Eurasian subduction zone, influenced by the Lampung-Panjang and Menanga Faults. Volcanic and volcaniclastic lithologies overlying thick alluvial sediments increase seismic amplification potential. This region hosts critical infrastructure inc...

Probabilistic seismic hazard assessment at bedrock conditions for the Jizan Region, Southwestern Saudi Arabia

The current work presents a probabilistic seismic hazard assessment (PSHA) for engineering bedrock conditions (Vs30} = 760 m/s) across the Jizan region of southwestern Saudi Arabia. For this purpose, we compiled a homogenised earthquake catalogue covering 827–2022 CE, including historical and instrumental records from...

Preliminary Seismic Hazard and Exposure Assessment of the Lombok Strait Strike-Slip Faults: A Comparative Analysis of the Mw 7.5 Southern and Mw 7.6 Northern Segments in Lombok Island

Lombok Island is situated within a complex tectonic environment shaped by subduction, back-arc thrusting, strike-slip faulting, and heterogeneous crustal structures. Despite this complexity, the ground-motion and population-exposure implications of the offshore Lombok Strait Strike-Slip Faults remain relatively underst...

Groundwater anomalies associated with seismic activity in the north fergana fault zone: Insights from the chartak no. 2 well

The paper presents long-term hydrogeoseismological investigations based on monitoring data from the Chartak No. 2 observation well, located within the North Fergana deep fault zone. The study aims to identify hydrogeoseismological anomalies associated with regional seismic activity using data collected during 2002–20...

Subsurface basin structure, seismic site conditions and earthquake damage: case study of the Gölbaşi basin, Türkiye

Gölbaşı (Adıyaman) Town, located within a basin along a left-stepping segment of the East Anatolian Fault Zone in Türkiye, experienced severe damage during the 6 February 2023 Mw 7.8 and Mw 7.6 Kahramanmaraş earthquakes. Widespread liquefaction, ground subsidence, lateral spreading, bearing capacity failures and bu...

Characterization of dynamic site properties in Quaternary-Tertiary geological formations using passive seismic techniques

This study presents a preliminary quantification of subsurface dynamic properties within the Quaternary-Tertiary geological formations in Jantho, Aceh Besar, Indonesia. The area lies near three major seismic sources, the subduction zone of the Indo-Australian plate under the Eurasian plate, the Great Sumatran Fault, an...
