As an historic pandemic ravaged the globe, Earth science as a whole has had to deal with major changes and delays...In spite of all the churn and change and challenges, we were still able to do some great work in geophysics and hydrogeology.
Geohazards have generally been understood and defined as events that take place on short human timescales, from milliseconds to a several months. However, both human- and naturally-induced events can develop and occur over the course of several years or longer. “Creeping hazards”—a term used as early as 1979 and referenced, though sparingly, in subsequent works—are a subset of events that exhibit the characteristics of geohazards (i.e., in terms of vulnerability, risk, and exposure). Distinct, but related to, “slow-onset” disasters, creeping hazards reflect permanent changes to a system. For example, although drought is often included as an example of such a hazard, drought is better understood as a slow-onset disaster. Better examples of a creeping hazard as defined here include aquifer depletion (and associated land subsidence), desertification, land degradation, certain hazards associated with climate change, and soil creep.
