INTRODUCTION

During the summer of 1998, gravity surveys were conducted in the vicinity of Los 

Angeles and Hollywood to improve control of basement depth estimates, to better characterize 

the Hollywood Fault, and to resolve the extent of a small sedimentary basin at the base of the 

Santa Monica Mountains. Approximately 300 new gravity stations were sampled; many stations 

were occupied at least twice in order to minimize error. The Hollywood study area is located at 

the base of the south flank of the Santa Monica Mountains, in the northern extent of the Los 

Angeles Basin. The boundaries of the study area are 34° 00' to 34° 08' N latitude and 118° 25' 

to 118° 12' W longitude. A map showing the location of the study area and station locations is 

shown in figure 1. An index map of the study area is shown in figure 2. The gravity base 

station used for control for these surveys, PB0104, is located at the Griffith Observatory, 

directly in front of the statue of Sir Isaac Newton, and is illustrated in figure 3. This base was 

established by the U. S. Geological Survey (USGS) prior to these field operations. The observed 

gravity of this station was calculated based on multiple ties to other high precision base stations 

in the region.

GRAVITY REDUCTION

Conversion of meter readings to milligals was made using factory calibration constants 

and a calibration factor which varies with each gravity meter and has been determined by 

multiple gravity readings over the Mt. Hamilton calibration loop east of San Jose, CA (Barnes et 

al, 1969). Observed gravity values were based on an assumed linear drift between successive 

base readings. Horizontal control was mostly provided by a small portable Global Positioning 

System (GPS). Error in the horizontal locations calculated by GPS was usually less than ±3 m. 

Vertical control was provided by City of Los Angeles, Department of Public Works, Survey 

Division, and theodolite total station surveys conducted by the USGS. Vertical error for the data 

provided by the Los Angeles Survey Division was ±0.002 m. In contrast the error associated 

with the USGS theodolite survey is about ±0.015 m. This data set includes five closely spaced 

profiles; four trend north-south, crossing the Hollywood Fault, and one runs east-west, along the 

axis of the Hollywood Basin. All profile stations were occupied at least twice.

These data were processed through an isostatic reduction program (Jachens and Roberts, 

1981) in order to suppress the effects of deep density distributions that buoyantly support the 

topography. The following corrections were used in conjunction with this program. Field 

terrain corrections were made in the field, which calculates the effect of local terrain from the
station to a radial distance of 68 m; inner terrain corrections from 68 m to 0.59 km were 

calculated using 30 m digital elevation models (OEM's) of the area. Terrain corrections were 

computed for the area from a radial distance of 0.59 km from the station to a radial distance of 

166.7 km with a FORTRAN program (Plouff, 1977) and a digital terrain model. The isostatic 

reduction assumes an Airy-Heiskanen model with the following parameters from the station to 

166.7 km: density of topography above sea level, 2.67 g/cm3 ; crustal thickness at sea level, 25 

km; density contrast between the crust and mantle, 0.4 g/cm3 . From 166.7 km to a point on the 

opposite side of the Earth, isostatic and terrain corrections were taken off maps by Karki (1961). 

These corrections were added to the output of the isostatic reduction program of Jachens and 

Roberts (1981) to produce the isostatic correction. With the isostatically corrected values we 

have attempted to remove the effects of deeper sources, so the data primarily represent gravity 

and density changes occurring in the upper-middle crust.

Theoretical gravity at sea level is based on the Geodetic Reference System 1967 (GRS 

67) (International Association of Geodesy, 1971) for the shape of the spheroid. The datum for 

the observed gravity is the International Gravity Standardization Net 1971 (IGSN 71); (Morelli, 

1974). Observed gravity values were calculated by adding meter drift and earth-tide corrections 

to the milligal equivalent meter readings.

Free-air anomalies are calculated by subtracting the theoretical gravity from the observed 

gravity and adding the free-air correction as defined by Swick, 1942.

Simple Bouguer anomalies are calculated by subtracting the Bouguer correction, which 

accounts for the attraction of rocks between the station and sea level using a rock density of 2.67 

g/cm3 from the free-air anomaly. Complete Bouguer anomalies are calculated by adding the 

terrain correction and the curvature correction to the simple Bouguer anomaly.

The isostatic residual anomaly is calculated by adding the isostatic correction to the 

complete Bouguer anomaly.
