Ambient noise tomography is one of the most important breakthroughs in seismological
research since the 21st century. The method does not depend on the occurrence of natural …

Seismic anisotropy of the upper crust beneath the eastern of south China block has been
studied by shear wave splitting analysis of local earthquakes recorded by the HN Array and …

Ambient noise interferometry between seismic stations makes it possible to monitor temporal
changes of the Earth's media continuously. Here, we examined seasonal changes of …

We have developed a minimal Portable Active Seismic Source (PASS) system for imaging
and monitoring geological formations. Stacking of the signals continuously generated by the …

This study explores the feasibility and limitations of using Rayleigh wave (Rg) ellipticity for
noise-based seismic monitoring at near-surface depths (4–70 m). We use the degree of …

背景噪声成像技术是21 世纪以来地震学研究最为重要的突破性进展之一. 该方法不依赖于天然
地震事件的发生, 利用连续地震记录中普遍存在的“背景噪声”, 通过不同台站对间连续时间信号的 …

Ambient noise interferometry has become a common technique for monitoring slight
changes in seismic velocity in a variety of contexts. However, the physical origin of the …

Abstract On 8 July 2020, an ML 4.2 earthquake occurred in the **aojiang fault zone along
the eastern margin of the Tibetan Plateau. Applied ambient noise monitoring technique to …

Advances in noise‐based velocity change measurements have revealed anomalies before
volcanic eruptions. Still, it is difficult to assign them to a certain depth based on the traditional …

For seismographic stations with short acquisition duration, the signal-to-noise ratios (SNRs)
of ambient noise cross-correlation functions (CCFs) are typically low, preventing us from …
