SACRAMENTO – During Earthquake Preparedness Month, Governor Gavin Newsom today announced a major milestone: the MyShake app – which alerts Californians before an earthquake begins – has surpassed 4 million downloads, the equivalent of more than 10% of the state. This achievement is a significant step in expanding access to California’s life-saving earthquake technology and building resilience across the state.
Launched under Governor Gavin Newsom’s leadership, California’s nation-leading Earthquake Early Warning system notifies residents in advance of shaking by using ground motion sensors across California. More than 60% of the 1,046 sensors have been installed since the program launched in 2019, making the system more accurate and able to deliver alerts faster.
Last week, the MyShake app distributed 693,044 alerts for the 5.2 magnitude earthquake near Julian in San Diego County, a subset of the total 7.5 million alerts sent out for that event. Some MyShake users received as much as 35 seconds notice before shaking occurred.
