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 72572475, which has the following hypoDD-RT solution:
Date: 2016/01/02 | Time: 00:14:17.990 | Latitude: 36.81862 | Longitude: -121.53704 | Depth: 5.833 | Magnitude: 1.50
Quality: 1 | Shift: 1.408 | 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 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 circles, those from the DD-RT catalog by colored circles.
There are 4420 earthquakes in the box. Magnitude cutoff is 1 (except for events within the last week).
