Geologists predict earthquakes by monitoring seismic activity using seismographs, studying fault lines, analyzing historical earthquake data, and looking for patterns in the movement of tectonic plates. They also use technology such as GPS and satellite imagery to track changes in the Earth's crust that may indicate an increased risk of an earthquake. It's important to note that while geologists can make educated guesses about where and when earthquakes may occur, predicting them with absolute certainty is still a major challenge.
