Special Issue Information

Dear Colleagues,

Technological improvements in sensors and advances in computational power, together with the increased number of satellites dedicated to Earth observation, have promoted a significant evolution in remote sensing science in the last decades.

Satellite-, aircraft-, and land-based geophysical, geodetic, and geochemical data have proved to be key tools to not only extensively map surface phenomena associated with tectonics and earthquakes, even for light-magnitude events, but also to depict tectonic strain, allowing the identification of areas of increased seismic risk.

Additionally, continuous data (in space and time) on slow surface displacement, e.g., post-seismic relaxation following large earthquakes, represent a precious reference for modeling the rheology of the crust and upper mantle in these regions.

Besides applications to natural seismic hazards, remote sensing techniques have also demonstrated the ability to detect the surface effects of underground industrial exploitation, providing timely information on the possible risks associated with induced seismicity and deformation caused by these anthropic activities.

More recently, the introduction of robot and drone technology in remote data acquisition has also facilitated more detailed characterizations of fault movements and monitoring of volcano tectonic activity, representing strong support in constraining the interpretation of satellite data.

Detecting surface deformation associated with low-magnitude (Mw5) seismicity using interferometric synthetic aperture radar (InSAR) is challenging due to the subtlety of the signal and the often challenging imaging environments. However, low-magnitude earthquakes are potential precursors to larger seismic events, and thus characterizing the crustal displacement associated with them is crucial for regional seismic hazard assessment. We combine InSAR time-series techniques with a Deep Learning (DL) autoencoder denoiser to detect the magnitude and extent of crustal deformation from the Mw=3.4 Gallina, New Mexico earthquake that occurred on 30 July 2020. Although InSAR alone cannot detect event-related deformation from such a low-magnitude seismic event, application of the DL method reveals maximum displacements as small as (±2.5 mm) in the vicinity of both the fault and earthquake epicenter without prior knowledge of the fault system. This finding improves small-scale displacement discernment with InSAR by an order of magnitude relative to previous studies. We additionally estimate best-fitting fault parameters associated with the observed deformation. The application of the DL technique unlocks the potential for low-magnitude earthquake studies, providing new insights into local fault geometries and potential risks from higher-magnitude earthquakes. This technique also permits low-magnitude event monitoring in areas where seismic networks are sparse, allowing for the possibility of global fault deformation monitoring. Full article
