The number of buildings threatened by flooding in the U.S. could be higher than previously thought, according to a study published Monday.

The study focused on North Carolina and found 43% of flooded buildings in the state between 1996 and 2020 were located outside the Federal Emergency Management Agency’s (FEMA) Special Flood Hazard Area. The agency predicts Special Flood Hazard Areas have a 1% risk of flooding each year, and flood insurance is mandatory for buildings in these areas.

The researchers said the study shows the value of simulating flood events beyond those that generate the most damage and get the most attention from governments, media, and researchers. A database of flood maps also can be used to better understand how flood exposure, vulnerability, and risk change over time, the researchers said.

Experts told NBC News that with access to the right data sources, databases like the one described in the study could be developed nationwide. Currently, FEMA’s maps are the main source nationally to identify flood-prone areas and buildings that need to be insured.

Entertainment studio Cineverse will release the U.S. debut of The Toxic Avenger on Aug. 29. Based on Lloyd Kaufman’s original 1984 horror/comedy, when a downtrodden janitor, Winston Gooze, is exposed to a catastrophic toxic accident, he’s transformed into a new kind of hero: The Toxic Avenger. Now, Toxie must rise from outcast to savior, taking on ruthless corporate overlords and corrupt forces who threaten his son, his friends, and his community. In a world where greed runs rampant… justice is best served radioactive.

Staring Peter Dinklage (Game of Thrones), Elijah Wood (The Lord of the Rings franchise), Jacob Tremblay (Room, Wonder), and Taylour Paige (Beverly Hills Cop: Axel F, Zola), the movie is written and directed by Macon Blair (I Don’t Feel at Home in This World Anymore, writer for Marvel Comics/Dark Horse Comics). Dinklage plays Winston Gooze armed with a signature mop and ready to battle gangsters and corrupt CEOs.

Before it hits theaters next month, the cast and director will host a panel on July 24 at San Diego Comic-Con in support of The Toxic Avenger. Taking place in Hall H, the panel will feature exclusive clips from the film, limited-edition swag for attendees, and behind-the-scenes chaos with the cast and creators.
