2013年2月19日四川省绵阳市三台县发生MS4.7地震,震中位于四川盆地中部基底断裂绵阳—三台—大足断裂与蒲江—三台—巴中断裂的交会区域。基于地震目录、震相报告和波形等资料,对地震序列进行重定位,采用近远震联合波形反演求解主震震源机制,结合野外地质调查对该地震的发震构造进行分析。余震序列重定位的空间展布方向为NW-SE向,与节面Ⅰ走向吻合,认为此次地震发震断裂走向为NW−SE,倾向为NE,且破裂面近于直立,发震断层在近NS向的近水平挤压应力作用下作右旋走滑错动。实地调查中未见地表破裂及地表断层行迹 ...

Abstract An intense seismic swarm started on 27 January 2025 in the Santorini‐Amorgos region and lasted for approximately 45 days. A widely observed seismic tremor on 14 February 2025 suggested a volcanic origin for the 2025 Santorini crisis. Here we present an in‐depth combined seismological analysis of the earthquakes and tremors that occurred during

With the recent increases in measured ground motion records for large earthquakes, most notably the 2023 M7.8 Pazarcik earthquake in Türkiye, the potential for pervasive high velocity fault rupture propagation over an extensive fault length has been observed.

This study investigates the effect of incorporating the Devil's Mountain Fault (DMF) and its interaction with the Leech River Valley Fault (LRVF) on the elastic surface deformation hazard in and near the city of Victoria, British Columbia, Canada. Previously, the surface deformation hazard of the region has been characterized by considering the LRVF ...

通过初至P震相定位法测定了2021年固原震群中ML≥3.0地震的震源深度,同时根据多阶段定位和微震匹配定位方法对该震群序列进行了重定位,基于Snoke方法和HASH方法计算了震群序列中ML≥2.8地震的震源机制解,并根据gCAP方法反演了震群中最大的地震即2021年6月22日固原ML3.6地震的震源机制解及矩心深度,确定了ML≥2.8地震基于各种方法所得震源机制的中心解,然后根据重定位结果拟合了断层面,最后初步分析了固原震群的发震构造。结果表明:微震检测到901次ML0.0以上地震事件 ...

From tomographic images to fault heterogeneities
Local Earthquake Tomography (LET) is a useful tool for imaging lateral heterogeneities in the upper crust. The pattern of P- and S-wave velocity anomalies, in relation to the seismicity distribution along active fault zones.

Abstract Statistical earthquake forecasting models, such as the Epidemic‐type Aftershock Sequence (ETAS), embed decades of empirical knowledge and assumptions about earthquake triggering, clustering, and catalog completeness. In contrast, neural spatio‐temporal point process (STPP) models often treat seismicity as generic spatiotemporal data without ...

From Risk Perception to Action: The Behavioral Forces Shaping Disaster Preparedness
Abstract The study examines the behavioral forces spanning cognitive, social, and environmental determinants that transform disaster risk perception into tangible preparedness actions. The case study at hand focuses on Bucharest, the European capital with the highest seismic risk.

New 2010 Maule Aftershock Catalog Reveals Structure of the Deep Subduction Interface
Abstract On 27 February 2010, a Mw 8.8 earthquake occurred near Maule in south‐central Chile. The subsequent rapid deployment of a dense network of seismic stations on land was able to capture the first year of its aftershock sequence. Here, we revisit this data set using picking Artificial Intelligence tools, a 3D velocity model of the region and ...
