This page uses the 3D JavaView viewer to show the real-time double-difference (DD-RT) location solution for event 72201145:

Date: 2014/04/17 | Time: 23:25:39.920 | Lat: 36.55110 | Long: -121.14276 | Depth: 7.066 | Mag: 1.70

Shift from initial location: 0.260 km | Version: 2.1

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 11263 earthquakes in the box. Magnitude cutoff is 1 (except for events within the last week).

Legend:

  • Red circle is hypoDD-RT solution for event 72201145 (M=1.70)
  • Events in previous HOUR | DAY | WEEK
  • DD-RT catalog (2012-present) (M>1)
  • DD catalog (1984-2011) (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.
