ABSTRACT:

Vibrating-wire extensometer (RST Instruments, model EXSR-1300) data from two sensor that spanned the active earthflow margin, one (MX1049) approximately two meters away from the shear zone piezometer (SNAP) and the other (MX1048) is on the same shear margin, but 125 downhill. MX1048 is in line with the UNAVCO ORE2 GPS station, which is in the center of the earthflow. MX1049 is in line with the UNAVCO OREO GPS station, which is in the center of the earthflow. The extensometers were buried to a depth of 20 cm and the long axis was oriented as close to parallel to the strike of the slickensided shear zone as possible, with the flanges located diagonally across from one another. The folder below contains matlab processing scripts for the raw extensometer data.

ABSTRACT:

These are data from a 1.2 m deep vibrating wire piezometer (RST Instruments, model VW2100-0.07) grouted in place near the center of Oak Ridge Earthflow. The borehole was manually excavated into mélange with a hand auger and backfilled with a grout slurry composed of water, cement, and bentonite (weight ratio = 2.49 : 1.00 : 0.41). The files below include a Matlab script to process the raw piezometer data, and apply ground temperature and air pressure corrections.

Oak Ridge Earthflow Observatory Data
Created: June 12, 2020, 3:12 p.m.
Authors: Finnegan, Noah

ABSTRACT:

Oak Ridge earthflow is a seasonally active earthflow located in the northern Diablo Range, 20 km northeast of San Jose, California. Positioned on the south-facing flank of Oak Ridge, it extends 1.35 km in the horizontal direction from ridge top to near the valley bottom, spans about 400 m of vertical relief, and has an average slope of 15°. The landslide body is composed of Franciscan mélange, an assemblage of variably deformed and metamorphosed rock units formed in a subduction zone during the Mesozoic and early Cenozoic eras.

ABSTRACT:

These are data from a 2.7 m deep vibrating wire piezometer (RST Instruments, model VW2100-0.07) grouted in place near the lateral shear margin of Oak Ridge Earthflow. The borehole was manually excavated into mélange with a hand auger and backfilled with a grout slurry composed of water, cement, and bentonite (weight ratio = 2.49 : 1.00 : 0.41). The files below include a Matlab script to process the raw piezometer data, and apply ground temperature and air pressure corrections.
