Event 72147965 M=0.80 - 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 72147965, which has the following hypoDD-RT solution:

Date: 2014/01/28 | Time: 11:49:18.140 | Latitude: 38.83222 | Longitude: -122.77123 | Depth: 2.317 | Magnitude: 0.80
Quality: 2 | Shift: 0.157 | Version: 0.1

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 9323 earthquakes in the box. Magnitude cutoff is 2 (except for events within the last week).

Legend:

  • Red circle is hypoDD-RT solution for event 72147965 (M=0.80)
  • Events in previous HOUR | DAY | WEEK
  • DD-RT catalog (2010-present) (M>2)
  • DD catalog (84-09) (M>2)
  • 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.
