Event 72860971 M=0.80 - 3D View

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 72860971, which has the following hypoDD-RT solution:

Date: 2017/08/05 | Time: 16:20:54.680 | Latitude: 38.81438 | Longitude: -122.78547 | Depth: 2.622 | Magnitude: 0.80
Quality: 1 | Shift: 1.272 | Version: 0.1

The 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 10419 earthquakes in the box. Magnitude cutoff is 2 (except for events within the last week).
