Green Valley Road landslide, plan view. The three tiltmeters were connected to a continuously recording, battery powered data logger in order to obtain an uninterrupted record of ground behavior over several months. A field technician retrieved the data biweekly and plotted it on a PC for review and analysis. Movement essentially stopped at this time, attesting to the effectiveness of the repair. Accelerated movement in early January 1989 corresponded to a period of heavy rainfall.
Little trend is apparent in the data.
Tiltmeter B data showed that the ground above the slide remained stable. Copyright 1999 Applied Geomechanics Incorporated. All rights reserved. This material may not be published, broadcast, rewritten or redistributed.
