The last decade has witnessed a renaissance in the breadth of applications of seismology, which extended into non-traditional areas with the aim of studying environmental processes. “Environmental seismology” is a rapidly growing, relatively new, and inherently multidisciplinary research field which allows us to monitor surface events also in absence of direct observations. In this talk, I will present novel findings on the study of mass-wasting events and ocean/atmospheric events using seismic signals. In the first part of my talk, I will show how we can infer dynamics, runout trajectory, mass and main characteristics of remote rockfalls and landslides by using seismic data analysis and numerical modelling. In the second part of my talk, I will show how we can employ decades of continuous seismic records, called ambient seismic noise, to estimate the time-dependent behavior and strength of strong atmospheric and oceanic events through extensive numerical simulations and machine-learning techniques.
