Event 73738896 M=1.80 - 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 73738896, which has the following hypoDD-RT solution:

Date: 2022/05/28 | Time: 08:58:0.440 | Latitude: 36.24273 | Longitude: -120.80628 | Depth: 5.897 | Magnitude: 1.80
Quality: 2 | Shift: 0.527 | Version: 2.1

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 base catalog for Northern California (NCAeqDD.v201112.1). Hypocenters from 2012 up to present are taken from the real-time double-difference catalog DD-RT (NCAeqDDRT.v201201). Earthquakes from the DD catalog are represented by gray dots, those from the DD-RT catalog by colored dots.

There are 2496 earthquakes in the box. Magnitude cutoff is 1 (except for events within the last week).
