In 2014, a massive landslide struck Oso, Washington. This disaster killed 43 people and erasing an entire community along the Stillaguamish River Valley. This is a true account of an ancient risk that stopped waiting — and broke loose and in 60 seconds, took a town with it.

The Oso landslide was not a mystery... and not an accident in the usual sense. It unfolded over decades, shaped by geology, rainfall, and how humans understand risk over time.

This episode of An Ounce examines what happened, why it happened, and what this disaster reveals about the space between knowing danger exists and recognizing it as real within time.
