Event 72151871 M=1.40 - 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 72151871, which has the following hypoDD-RT solution:

Date: 2014/01/29 | Time: 11:39:47.960 | Latitude: 36.78348 | Longitude: -120.91790 | Depth: 8.378 | Magnitude: 1.40
Quality: 1 | Shift: 2.655 | Version: 2.1

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

Legend:

  • Red circle is hypoDD-RT solution for event 72151871 (M=1.40)
  • 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.
