Earth’s history, structure, and change is archived in our rocks. Through the lens of geophysics, structural geology, stratigraphy, palaeontology, and sedimentology we can reveal how our planet has changed in the past and is undergoing change today.
Seismic arrays are installations where several seismic sensors are typically distributed over an aperture covering up to 10 km or more. Routine array signal processing is applied to the data streams recorded. This generates near-realtime estimates of direction-of-arrival for impinging signals that, for example, are due to earthquakes.
Globally, seismic data from arrays have proven to be of great value, for example, in characterization of earthquakes, in monitoring that the nuclear test-ban-treaties to limit nuclear testing, in vulcanology, in glaciology, in monitoring CO2 storage sites, and beyond.
