Tectonic plates move slowly, from 2 to 10 centimeters each year⁸. These movements cause stress that can lead to disasters. The Ring of Fire shows how tectonic activity focuses in certain areas⁹.

Earthquake Zones and Risks

Earthquake zones are where plates meet, releasing a lot of energy. The San Andreas Fault is a good example, where the Pacific and North American Plates meet⁹. It moves about 5 to 6 cm each year, making big earthquakes possible⁹.

Plate boundaries generate most significant earthquakes
Subduction zones produce most destructive quakes⁸
Geological stress accumulates over time, leading to potential disasters

“Understanding plate tectonics is crucial for predicting and mitigating natural disaster risks.”

Today, we have better tools to track earthquakes, with over 26,000 stations worldwide⁸. These help scientists predict and warn about disasters, saving lives in danger zones⁸.
