6.2的强烈地震，震中位于亚平宁山脉中部，尽管震级适中，但由于震源浅、破裂面复杂等特点，导致了严重的地震灾害。本研究基于经验格林函数（Empirical Green's function， EGF）法，利用0.2~2.0 Hz频段的近断层强震数据，反演了Amatrice地震的震源破裂过程。研究结果表明：地震破裂的最大滑动量集中分布区域在震源西北约5 km和东南约4 km的浅层区域，最大滑动量为1.5 m，深度约3.5 km，破裂速度为3.0 km/s。研究进一步通过多组EGF事件组合的敏感性分析、模拟未参与反演分析的强震观测台站波形与观测数据（0.2~2.0 Hz频段）、与基于不同频段地震动数据反演的震源模型对比，充分验证了反演的震源模型的稳健性与可靠性。研究结果对浅源地震引起的地震动模拟及抗震设计具有重要的学术和工程意义，特别是可为近断层工程结构的抗震设计提供关键参数。

Abstract

On August 24

2016

a strong earthquake with a magnitude of

6.2 occurred in the Amatrice region of Italy

with the epicenter located in the central Apennine Mountains. Despite the moderate magnitude

the shallow depth and complex fault rupture led to severe seismic damage. This study employed the Empirical Green's Function (EGF) method and inverted the source rupture process of the Amatrice earthquake

utilizing near-fault strong-motion data in the frequency range of 0.2~2.0 Hz. The results indicated that the area of maximum slip on the earthquake rupture was primarily concentrated in the shallow regions approximately 5 km to the northwest and 4 km to the southeast of the hypocenter

with a maximum slip of 1.5 m at a depth of 3.5 km. The inverted rupture velocity was 3.0 km/s. To validate the robustness and reliability of the proposed source model

sensitivity analyses of multiple EGF event combinations were performed

synthetic waveforms at strong-motion stations not used in the inversion were compared with their observed records (0.2‑2.0 Hz)

and comparisons with source models inverted from different frequency bands were conducted. The findings have significant academic and engineering implications for simulating ground motion ind

uced by shallow earthquakes and for seismic design

especially in providing critical parameters for the seismic design of near-fault engineering structures.
