Event 75064221 M=0.30 - 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 75064221, which has the following hypoDD-RT solution:

Date: 2024/09/20 | Time: 00:30:43.750 | Latitude: 38.84027 | Longitude: -122.82359 | Depth: 2.593 | Magnitude: 0.30
Quality: 2 | Shift: 0.815 | 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 10857 earthquakes in the box. Magnitude cutoff is 2 (except for events within the last week).

Legend:

  • Red dot is hypoDD-RT solution for event 75064221 (M=0.30)
  • Events in previous HOUR | DAY | WEEK
  • DD-RT catalog (2010-present) (M>2)
  • DD catalog (84-09) (M>2)
  • Larger dots: M>4
  • White dot is original (NCSN) location
  • Brown lines at surface: faults from USGS
  • Top square of the bounding box has green/blue sides, blue on the North.
