What modern technology allows for predicting the probability of an earthquake by assessing build-up of stress along faults?

1. Seismographs

2. GPS technology

3. Remote sensing

4. Satellite imagery

The correct answer is: GPS technology

GPS technology is instrumental in predicting the probability of an earthquake by enabling continuous monitoring of the Earth's crustal movements. This technology uses a network of satellites to track minute ground deformations and shifts along fault lines. As tectonic plates move, any build-up of stress along these faults can be detected through changes in position measured by GPS instruments. By analyzing this data over time, scientists can identify patterns and assess the likelihood of an earthquake occurring in a particular area. The high accuracy and real-time nature of GPS technology provide valuable insights into the dynamics of tectonic activity, making it a crucial tool in earthquake prediction efforts. While other technologies, such as seismographs, are essential for detecting and recording seismic activity after it occurs, they do not predict earthquakes in advance. Remote sensing and satellite imagery are also useful in studying geological features but lack the precision in real-time monitoring that GPS offers, specifically in tracking stress accumulation along faults.
