Event 75153492 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 75153492, which has the following hypoDD-RT solution:

Date: 2025/03/22 | Time: 23:12:4.470 | Latitude: 39.26653 | Longitude: -123.48532 | Depth: 6.058 | Magnitude: 1.80
Quality: 2 | Shift: 0.593 | 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 196 earthquakes in the box. Magnitude cutoff is 1 (except for events within the last week).
