LARSE '94 MARINE-LAND EXPERIMENT
In October of 1994, as part of the Los Angeles Regional Seismic Experiment (LARSE), deep crustal
multichannel seismic-reflection data was collected aboard the
R/V Maurice Ewing. The emphasis was placed on collecting data along
three long onshore-offshore lines (Lines 1, 2 and 3) . These lines included:
LINE 1 - trended N-S from the center of San Clemente Island through
Seal Beach projecting into the 1933 Long Beach earthquake epicenter and the
These three lines provide a general reconnaissance of the crustal structure
in the vicinity of two recent, damaging earthquakes in the greater Los Angeles
LINE 2 - trended N-S along the western shores of San Clemente and
Catalina Islands through Santa Monica, and projected through the 1994
Northridge earthquake epicenter.
LINE 3 - trended NE-SW from northwest of San Nicolas Island through
the center of the Los Angeles Basin.
The equipment and procedures used to acquire the multichannel seismic reflection
and other geophysical data aboard the Ewing, data reduction processes and near-trace
constant offset seismic sections of the aquired profiles are presented in the
following Open File Report.
