Sensor Technologies
Sensor Technologies is a skill on Pengi from Lesson 2: Engineering Trade-offs in Amplify Science (California) Grade 7.
Key Concepts
Detecting a tsunami requires specialized technology. Seismic sensors provide the fastest data by detecting ground shaking, but they cannot confirm if a wave has formed. Deep water sensors (like DART buoys) measure pressure changes on the seafloor, offering high accuracy but coming with a high price tag.
Shallow water sensors offer a cheaper alternative near the coast, though they provide very little warning time. Each sensor type functions differently, offering unique advantages regarding speed, cost, and information quality.
