COVID-19 societal response captured by seismic noise in China and Italy

, 2020
Seismic noise with frequencies above 1 Hz is often called cultural noise and is generally correlated quite well with human activities. Recently, cities in mainland China and Italy imposed lockdown restrictions in response to COVID-19, which gave us an ...

Separation of Body and Surface Wave Background Noise and Passive Seismic Interferometry Based on Synchrosqueezed Continuous Wavelet Transform

Applied Sciences
Passive seismic interferometry is a technique that reconstructs virtual seismic records using ambient noise, such as random noise or microseisms. The ambient noise in passive seismic data contains rich information, with surface waves being useful for the

Review of temporal variations of underground medium based on seismic waves

地球与行星物理论评
As a vibrant and ever-evolving planet, the Earth has a dynamic evolution process spanning more than a dozen orders of magnitude from seconds (e.g., seismic rupture) to millions of years (e.g., mantle convection).

Characterizing South Pole Firn Structure With Fiber Optic Sensing

Geophysical Research Letters
The firn layer covers 98% of Antarctica's ice sheets, protecting underlying glacial ice from the external environment. Accurate measurement of firn properties is essential for assessing cryosphere mass balance and climate change impacts.
