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 75016392, which has the following hypoDD-RT solution:
Date: 2024/06/04 | Time: 23:57:27.970 | Latitude: 38.82373 | Longitude: -122.81598 | Depth: 2.699 | Magnitude: 1.10
Quality: 2 | Shift: 0.788 | 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 11353 earthquakes in the box. Magnitude cutoff is 2 (except for events within the last week).
