Earth's Pulse: Hazard Monitoring

2007 (approx.)

Detailed Description

Scientists rely on measurements and networks of sensors to monitor Earth’s movements. Similar to tracking someone’s pulse, these sensors check the ‘hazard heartbeat’ of Earth’s surface, waters, and air. Hazard monitoring helps us understand where, when, why, and how much things change over time.
