Three-Dimensional Processing of Reflections for Passive-Source Seismology Based on Geometric Design
Applied Sciences, 2023 Passive-source exploration is a method of seismic exploration that has loose requirements on the conditions of the surface, is cheap, and does not require excitation by an active source.

Lab and Field Tests of a Low‐Cost 3‐Component Seismometer for Shallow Passive Seismic Applications
Earth and Space Science, 2023 We performed laboratory tests and field surveys to evaluate the performance of a low‐cost 3‐component seismometer, consisting of three passive electromagnetic spring‐mass sensors, whose 4.5 Hz natural frequency is extended down to 0.5 Hz thanks to hyper ...
