This page uses the 3D JavaView viewer to show the real-time double-difference (DD-RT) location solution for event 72295461:

Date: 2014/09/09 | Time: 23:31:32.560 | Lat: 38.80456 | Long: -122.77457 | Depth: 0.363 | Mag: 0.80

Shift from initial location: 1.011 km | Version: 0.1

The box below is centered on the event's hypocenter (red), and includes high-resolution background seismicity for Northern California
from both the DD base catalog (1984-2011, NCAeqDD) and the DD-RT real-time catalog (2012-present; NCAeqDD-RT).
Earthquakes from the DD catalog are shown in gray, those from the DD-RT catalog in yellow.

There are 9836 earthquakes in the box. Magnitude cutoff is 2 (except for events within the last week).

Legend:

  • Red circle is hypoDD-RT solution for event 72295461 (M=0.80)
  • Events in previous HOUR | DAY | WEEK
  • DD-RT catalog (2012-present) (M>2)
  • DD catalog (1984-2011) (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.
