Local officials say such small quakes are not unusual for the Bay Area, but the <strong>frequency \u2014 not just the magnitude \u2014 is stoking public concern.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Earthquake Swarms: Normal or a Sign of Something Bigger?<\/strong><\/h3>\n\n\n\n<p>Many of the recent quakes near San Ramon are part of what scientists call an <strong>earthquake swarm<\/strong> \u2014 clusters of small tremors without a single obvious mainshock. These can persist for days or weeks.<\/p>\n\n\n\n<p><strong>Scientists generally describe these swarms as \u201cnormal seismic behavior,\u201d<\/strong> especially along active faults like the <strong>Calaveras Fault<\/strong> beneath the Tri-Valley. But the daily rattling has left some residents anxious and wondering if this could be a prelude to a larger quake \u2014 <strong>even though experts caution that swarms don\u2019t reliably predict big events.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Why the Controversy?

Seismic monitoring has become more sensitive, so we detect more smaller events than in past decades.
