Fig. 5.10. The liquefaction field sitethoroughly characterized through geotechnical
borehole samples, and the nearby sitepreviously studied by the USGS
Seismic records from the WLA site provide essential information about the liquefaction
phenomenon. In particular, predicting the ground response, ground failure, and
liquefaction effects from earthquakes using computer models requires such an instru-
mented siteto validate the simulation methods against real observations.
Researchers are using earthquakes that occur on a daily basis near this site, as well as
active testing using mobile shakers to try to better understand how the near-surface geo-
logic conditions affect theground shaking at thislocation.
