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 73693791, which has the following hypoDD-RT solution:
Date: 2022/02/16 | Time: 20:06:36.960 | Latitude: 35.93804 | Longitude: -120.48658 | Depth: 5.625 | Magnitude: 1.10
Quality: 2 | Shift: 0.785 | 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 5036 earthquakes in the box. Magnitude cutoff is 1 (except for events within the last week).
