Forests are increasingly threatened by climate-change-fuelled cycles of drought, dieback
and wildfires. However, for reasons that remain incompletely understood, some forest stands …

Seismic refraction tomography provides images of the elastic properties of subsurface
materials in landslide settings. Seismic velocities are sensitive to changes in moisture …

Electrical conductivity tomography is a well-established galvanometric method for imaging
the subsurface electrical conductivity distribution. We characterize the conductivity …

An accepted paradigm of hydrothermal systems is the process of phase separation, or
boiling, of a deep, homogeneous hydrothermal fluid as it ascends through the subsurface …

The simultaneous estimation of 2D pressure (P-) and S-wave velocities (VP and VS,
respectively) is a promising approach for imaging subsurface mechanical properties. It can …

Improving our understanding of the relation between the water content and the seismic
signatures of unconsolidated superficial soils is an important objective in the overall field of …

A well‐developed soil structure is a key attribute of a productive and functioning soil.
Evidence shows that subtle changes in the spatial arrangement and binding of soil …

The vadose zone is the main host of surface and subsurface water exchange and has
important implications for ecosystems functioning, climate sciences, geotechnical …

Seismic tomography can be used to image the spatial variation of rock properties within
complex geological media such as volcanoes. Solfatara is a volcano located within the …

Core Ideas Saturation changes can be monitored with ambient seismic noise. We present a
new and nondestructive tool to investigate deep and heterogeneous vadose zones. At the …
