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 73800111, which has the following hypoDD-RT solution:
Date: 2022/10/28 | Time: 03:57:37.250 | Latitude: 37.61141 | Longitude: -118.85848 | Depth: 4.610 | Magnitude: -0.20
Quality: 1 | Shift: 1.732 | Version: 3.1The 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 18984 earthquakes in the box. Magnitude cutoff is 1.5 (except for events within the last week).
