Slow-slip events (SSEs) are slow earthquake ruptures that generate just a few centimeters of slip over periods ranging from days to years. They are thought to occur in many of the world’s subduction zones, but these subtle slips can be tricky to observe, especially when they happen under the ocean, where monitoring capabilities are often more limited than on land.
