This page uses the Three.js 3D JavaScript library to show real-time double-difference hypocenter locations of earthquakes in Northern California. The box below is centered on event 75069741, which has the following hypoDD-RT solution:
Date: 2024/10/03 | Time: 02:51:8.220 | Latitude: 37.59598 | Longitude: -119.01125 | Depth: 5.092 | Magnitude: 0.60
Quality: 1 | Shift: 3.113 | Version: 2.1The high-resolution background seismicity included in the box comes from two double-difference catalogs. Hypocenters for the years 1984-2011 are taken from the DD base catalog for Northern California (NCAeqDD.v201112.1). Hypocenters from 2012 up to present are taken from the real-time double-difference catalog DD-RT (NCAeqDDRT.v201201). Earthquakes from the DD catalog are represented by gray dots, those from the DD-RT catalog by colored dots.
There are 17556 earthquakes in the box. Magnitude cutoff is 1 (except for events within the last week).
