Map of the southern section of the Walker Lane Belt around surrounding regions showing the the past 30 days of earthquake activity. The three stars indicate important quakes—the July 2019 Ridgecrest magnitude-6.4 foreshock, the July 2019 Ridgecrest magnitude-7.1 mainshock, and the Tonopah magnitude-6.5 event of May 15, 2020. Stars are scaled to correspond with magnitude. Credit: Temblor
