Aftershock monitoring

Immediately following the earthquake a multi-institution effort was initiated to deploy seismic instruments in the source zone of the August 23, 2011 earthquake. This summarizes the deployment geometry in relation to the earthquake locations:

Aftershocks

ANSS solutions

The ANSS list of larger earthquake in the source region is given at the link
http://earthquake.usgs.gov/earthquakes/recenteqsus/Maps/US2/37.39.-79.-77_eqs.php

SLU solutions

As of August 29, ANSS solution use the same data streams as the SLU solution, but focus on the larger earthquakes. The SLU solutions provide locations for all events with NetQuake triggers that are posted on the NetQuakes page. The station 791 seems most sensitive and its plots are used to start the location processing.

Vertical Profile centered 37.94N 77.95W in direction of N030E (for positive x)


Vertical Profile centered 37.94N 77.95W in direction of N120E (for positive x)
Neglecting the two shallow outliers, this orientation gives best planar fit. The inferred plane dips down 46 degrees to the east-southeast.



Vertical profile in direction N120E with projected moment tensors. The blue colors indicate the earlier solutions before the operation of the earthquake monitoring network. The red colors indicate solutions whose hypocentral coordinates are well known.

The following is a tabulation of the earthquakes plotted on the figure above. The yellow colored symbols are ANSS solutions. The red colors are SLU elocate solutions using real time waveform data in the NEIC CWB. The SLU solutions are initiated by an examination of the NetQuake waveform page http://earthquake.usgs.gov/monitoring/netquakes/station/NQ794_NQ_01/, and also for 791, 792 and 793 substituted for 794. This is not a process of examining continuous data streams.

Waveforms in Sac format are available.
