Event 72168931 M=3.20 - 3D View

This page uses the 3D JavaView viewer to show real-time double-difference hypocenter locations of earthquakes in Northern California. The box below is centered on event 72168931, which has the following hypoDD-RT solution:

Date: 2014/02/16 | Time: 16:31:4.710 | Latitude: 35.87006 | Longitude: -121.48390 | Depth: 9.802 | Magnitude: 3.20
Quality: 1 | Shift: 0.981 | Version: 5.1

The high-resolution background seismicity included in the box comes from two double-difference catalogs. Hypocenters for the years 1984-2009 are taken from the DD catalog for Northern California (NCAeqDD.v200912.1). 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 circles, those from the DD-RT catalog by colored circles.

There are 112 earthquakes in the box. Magnitude cutoff is 1 (except for events within the last week).

Legend:

  • Red circle is hypoDD-RT solution for event 72168931 (M=3.20)
  • Events in previous HOUR | DAY | WEEK
  • DD-RT catalog (2010-present) (M>1)
  • DD catalog (84-09) (M>1)
  • Larger circles: M>4
  • Green circle is original (NCSN) location
  • Red lines: faults from USGS
  • Top square of the bounding box has green/blue sides, blue on the North.
  • XYZ box dimensions (km) = 15.0 x 15.0 x 15.0.
