A critical component of managing the effect of debris flow is to know when and where it may happen next. That’s where USGS involvement begins.

"Technical Readiness Level (TRL) is a metric used to assess the maturity of a technology. The scale consists of nine levels where each level characterizes the progress in the development of a technology, from the initial idea (Level 1) to the full uptake of the product into the marketplace (Level 9) .
The objective of BRIGAID is to provide innovators with guidance to develop testing plans which increase the TRL of an innovation and its potential for market uptake."

Bridging the Gap for Innovations in Disaster Resilience BRIGAID is a 4-year project (2016-2020) under EU Horizon2020 aimed to effectively bridge the gap between innovators and end-users in resilience to floods, droughts and extreme weather. Europe is particularly prone to these natural hazards and e...

Earthquake lights? Well, yes, apparently.

"A characteristic feature of seismic luminosities (and other earthquake‐associated phenomena) is the observation that most EQL are seen before and/or during an earthquake, but rarely after the release and dissipation of the seismic‐stress energy in the crust. This strongly suggests that the processes responsible for EQL formation are related to a rapid build‐up of stress prior to fault rupture and rapid stress changes during the actual fault movement.

Based on our compilation, most pre‐earthquake luminosities have been observed from a few seconds to up to 3–4 weeks prior to seismic events, such as the Saguenay earthquake (St‐Laurent, 2000). The duration of EQL varies from less than a second to several minutes. They vary in shape and extent, the most frequent occurrences being globular luminous masses, stationary in the air or moving. Light emission during the time of seismic activity, termed coseismic luminosity, is most frequently observed as either short flashes of light shooting high up into the air, diffuse but relatively bright atmospheric illuminations that last from seconds to a few minutes, or flame‐like luminosities coming out of the ground." (Theriault et al., 2014).
