Earthquake sensors can detect disastrous floods

Earthquake sensors can detect fast-moving floods barreling toward them, new research finds. That information is especially valuable to people working on early warning systems for floods, which could give people crucial time to get to safety, preventing deaths and flood damage, according to the authors of a recently published paper.

Communities in Germany’s Ahr Valley experienced a devastating flood that washed away homes and killed almost 200 people in July 2021. Studying that disaster, the researchers discovered that a nearby seismometer station — intended to monitor earthquakes — detected valuable details about the flood as it was happening.

“If the data stream from that station had been available and analysed as our research now...
