    Is California overdue for a major earthquake?

    California is located in a hot-zone of fault lines that can rupture without warning. Parts of the San Andreas fault have not ruptured in over 200 years, meaning it’s overdue for a high-magnitude earthquake commonly referred to as “The Big One.”



    What are the signs of a big earthquake coming?

    Signs that an earthquakes may occur include foreshocks, ground tilting, water levels in wells, and the relative arrival times of P- and S-waves.

    The analysis of seismic activity by Rystad Energy reveals that tremors of above the magnitude of 2 on the Richter scale quadrupled in 2020 and are on track to increase even further in frequency in 2021 if oil and gas activity sticks to its current drilling methods at the same pace.

    When’s the next big earthquake in California?

    The threat of earthquakes extends across the entire San Francisco Bay region, and a major quake is likely before 2032. Knowing this will help people make informed decisions as they continue to prepare for future quakes.
