A new study uncovered hidden activity on California's fault lines.

Last January 19, 2026, residents in the Coachella Valley felt quite shook. It wasn't any celebrity drama or local gossip, but a literal 4.9 earthquake.

By tracking swarms of very small earthquakes, seismologists are getting a new picture of the complex region where the San Andreas fault meets the Cascadia subduction zone, an area that could give rise to devastating major earthquakes.

It was a groundbreaking discovery. Scientists have found previously concealed fault lines along California’s north coast, sparking concerns that we could be drastically underestimating the earthquake risk in the region,

Scientists are uncovering a hidden and surprisingly complex earthquake zone beneath Northern California by tracking swarms of tiny earthquakes that are far too weak to feel. These faint tremors are revealing what lies beneath the surface where the San Andreas fault meets the Cascadia subduction zone,

When it comes to emergencies and natural disasters, one of the main concerns for residents in California is earthquakes. World-renowned seismologist Dr. Lucy Jones says the San Andreas Fault is not the only show in town. Jones added that there are hundreds ...
