The discipline of seismology is based on observations of ground motion that are inherently
undersampled in space and time. Our basic understanding of earthquake processes and our …

Monitoring landslides is essential to understand their dynamics and to reduce the risk of
human losses by raising warnings before a failure. A decade ago, a decrease of apparent …

Historic levels of drought, globally, call for sustainable freshwater management. Under
pressing demand is a refined understanding of the structures and dynamics of groundwater …

Aquifers are vital groundwater reservoirs for residential, agricultural, and industrial activities
worldwide. Tracking their state with high temporal and spatial resolution is critical for water …

We demonstrate the feasibility of detecting very weak deformation in the shallow crust with
high temporal resolution by monitoring the relative changes in seismic wave velocity (dv/v) …

The spatial distribution of temporal variations in seismic wavespeed is key to understanding
the sources and physical mechanisms of various geophysical processes. The imaging of …

Through the release of groundwater, most mountain rivers run year‐round despite their
small catchments and sporadic precipitation. This makes mountain ranges important …

The fast‐growing interests in high spatial resolution of seismic imaging and high temporal
resolution of seismic monitoring pose great challenges for fast, efficient, and stable data …

Seismic noise interferometry is an exciting technique for studying volcanoes, providing a
continuous measurement of seismic velocity changes (dv/v), which are sensitive to …

A large fraction of volcanic eruptions does not expel magma at the surface. Such an eruption
occurred at Mt Ontake in 2014, claiming the life of at least 58 hikers in what became the …
