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 73516235, which has the following hypoDD-RT solution:
Date: 2021/01/25 | Time: 10:38:45.910 | Latitude: 35.55769 | Longitude: -120.81176 | Depth: 3.694 | Magnitude: 2.40
Quality: 2 | Shift: 0.698 | Version: 4.1The 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 5693 earthquakes in the box. Magnitude cutoff is 1 (except for events within the last week).
