Hidden Faults Found in California Earthquake Hotspot
Scientists have found hidden faults under Northern California.
They studied tiny earthquakes to map these faults, which are under the ground.
They discovered that there are five moving pieces of Earth's crust instead of three.
This helps explain why a big earthquake happened in 1992.
Understanding these hidden faults is important for predicting future earthquakes and keeping people safe.
Scientists discovered hidden fault structures beneath Northern California's Mendocino Triple Junction.
The region is a complex earthquake zone where three major tectonic plates meet.
Researchers found five interacting tectonic plates, including two hidden fragments.
The study used low-frequency microquakes to map the hidden faults.
The findings help explain the 1992 magnitude 7.2 earthquake and improve seismic hazard forecasts.
