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 73372190, which has the following hypoDD-RT solution:
Date: 2020/04/17 | Time: 19:00:43.380 | Latitude: 37.66237 | Longitude: -118.85911 | Depth: 4.074 | Magnitude: 0.30
Quality: 2 | Shift: 2.826 | 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 14210 earthquakes in the box. Magnitude cutoff is 1.5 (except for events within the last week).
