Natural Hazards Engineering Research Infrastructure

We all have experienced natural hazards in our lives: earthquakes, hurricanes, tornadoes, tsunami, floods: they impact our society at the most fundamental levels. Through rigorous testing and outreach programs, the team at the Natural Hazards Engineering Research Infrastructure is committed to making sure the next natural hazard doesn"t have to be a disaster for you and your family.

Episode 3 Understanding major storms: key to coastal resilience Understanding the behavior of coastal systems requires specialized researchers, including engineers, to instrument shorelines before a major storm — and to collect and analyze the resulting data. Woods Hole scientist Britt Raubenheimer reiterates the vital importance of federal funding, including NSF funding, which allows for multidisciplinary teams like NEER to perform nested, coordinated reconnaissance missions with NHERI engineers

Episode 1: Wind engineers hunt dust devils Dust devils! Understanding how these short-lived whirlwinds behave may help wind engineers understand tornadoes. In field studies, U of Illinois wind engineer Frank Lombardo collects data on dust devils, which occur more frequently – and are easier (and safer) to capture – than their high-powered relatives. Lombardo’s team has recorded more than 50 of these brief, 45 MPH windstorms. Find out how, where, and what the data show. Wind Engineering Research Lab,

U of Nevada earthquake engineer Keri Ryan shows us the external wall units on the 10-story NHERI Tallwood building: spandrels with ribbon windows and glass curtain walls, called mullions. Architects as well as engineers want to see how such non-structural elements perform under earthquake loading. During the March 2023 shake table test, more than 750 sensor channels will record behaviors like drift, acceleration, and joint slip and movement.
