This $50 earthquake early warning system has the potential to save billions of lives. From Mexico City-based startup Grillo, the alternative device provides a solution for developing countries who can't afford the average $20,000 measurement device.
The earthquake early warning system consists of a small cube and a bypass of information-relaying systems. The Grillo Active is similar to today's smartphones, as it contains features like an accelerometer, GPS and wifi capabilities. It relies on wide sensor placement, so the more are installed, the better. Algorithms look at a variety of factors (like nearby faults) before broadcasting warnings to affected areas, when activity is detected. The Grillo dashboard compiles the gathered data, making recorded seismic activity easily accessible.
