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 73331011, which has the following hypoDD-RT solution:
Date: 2020/01/24 | Time: 03:23:22.050 | Latitude: 37.65153 | Longitude: -118.91497 | Depth: 7.196 | Magnitude: 0.90
Quality: 2 | Shift: 3.096 | 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 catalog for Northern California (NCAeqDD.v201112.1). Hypocenters from 2010 up to present are taken from the real-time double-difference catalog DD-RT (NCAeqDD-RT.v201001). Earthquakes from the DD catalog are represented by gray dots, those from the DD-RT catalog by colored dots.
There are 14808 earthquakes in the box. Magnitude cutoff is 1.5 (except for events within the last week).
