Event 73677581 M=1.60 - 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 73677581, which has the following hypoDD-RT solution:

Date: 2022/01/12 | Time: 18:37:11.340 | Latitude: 36.96020 | Longitude: -119.85054 | Depth: 10.281 | Magnitude: 1.60
Quality: 2 | Shift: 0.394 | Version: 5.3

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

Legend:

  • Red dot is hypoDD-RT solution for event 73677581 (M=1.60)
  • Events in previous HOUR | DAY | WEEK
  • DD-RT catalog (2010-present) (M>1)
  • DD catalog (84-09) (M>1)
  • Larger dots: M>4
  • White dot is original (NCSN) location
  • Brown lines at surface: faults from USGS
