Key Technologies Used by PRSN:
- Seismometers: These instruments measure the ground motion caused by seismic waves. The PRSN uses a network of seismometers spread across Puerto Rico to detect even minor earthquakes.
- Accelerometers: These devices measure the acceleration of the ground. They are used to detect strong earthquakes and provide data on the potential for damage to buildings and infrastructure.
- GPS Sensors: The PRSN also uses GPS technology to track any slow movements of the earth’s crust, which may indicate long-term changes in tectonic stress that could lead to future earthquakes.
- Seismic Arrays: A seismic array is a group of seismometers located close to each other, which helps scientists accurately locate the epicenter of an earthquake.
How It Works:
- Real-time Data Collection: Seismometers and other instruments continuously send data to a central processing facility, where the information is analyzed.
- Earthquake Detection: When an earthquake occurs, the sensors immediately detect the seismic waves and record the event’s intensity, depth, and location.
- Data Transmission: Data is transmitted to the PRSN’s central system for immediate analysis and distribution.
Early Warning System:
The PRSN has contributed to the development of an early warning system for Puerto Rico, which can alert residents before the seismic waves from a large earthquake reach their location. These warnings can help people take protective actions, such as taking cover or evacuating vulnerable areas.
4. Seismic Stations and Equipment
