Analysis of Site Liquefaction Using Earthquake Records

A one-of-a-kind set of surface and downhole acceleration and pore
pressure records were recovered at the Wildlife Refuge site (Imperial
country, southern California) during the 1987 Superstition Hills earthquake
(Holzer, Youd, and Hanks 1989).
These records documented for the first time ever the phenomenon
of seismically induced site liquefaction. An analysis of these
records produced valuable insight into the site seismic behavior
during liquefaction and associated loss of soil stiffness. This analysis
is summarized in the following sections, and is fully detailed in the article
entitled ``Analysis of Site Liquefaction Using Earthquake Records,''
M. Zeghal, and A.-W. Elgamal, Journal of Geotechnical Engineering,
ASCE, Vol. 120 No. 6, pp. 996-1017, June 1994.
The site description, recorded data, and its interpretation were presented
in T. L. Holzer, T. L. Youd and T. C. Hanks, ``Dynamics of Liquefaction
During the 1987 Superstition Hills, California, Earthquake,'' Science,
Vol. 244, pp. 56-59, 1989; and in T. L. Youd and T. L. Holzer
``Piezometer Performance at the Wildlife Liquefaction Site,'' Journal
of Geotechnical Engineering, ASCE, Vol. 120, No. 6, 975-995, June 1994.
