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 75089641, which has the following hypoDD-RT solution:
Date: 2024/11/24 | Time: 03:28:16.560 | Latitude: 38.78925 | Longitude: -122.81477 | Depth: 4.186 | Magnitude: 0.60
Quality: 1 | Shift: 1.006 | Version: 0.1The 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 11290 earthquakes in the box. Magnitude cutoff is 2 (except for events within the last week).
