When will a particular city on the Eastern Seaboard have a 70% chance of flooding at least one hour on at least 70 days of the year? This jam-packed question drives this study, as…

Machine learning has been widely applied in numerical weather prediction, but the incorporation of new observational sites into models trained on stations with long historical rec…

Large earthquakes are usually modeled with simple planar fault surfaces or a combination of several planar fault segments. However, in general, earthquakes occur on faults that ar…
