Monitoring data from the Aleppo rockslide, Allegheny County, Pennsylvania, November 2013 - December 2018
type: Dataset
description: Upon reactivation, movement of deep-seated landslides in the Greater Pittsburgh region may persist for long periods of time. Monitoring equipment was located at two sites on a deep-seated rockslide in Aleppo Township, Pennsylvania to establish relationships between precipitation and changes in the state of activity and velocity. Precipitation, snow depth, and air temperature are monitored at a weather station (ARS_WS) located in a relatively flat, open area in the northern part of the rockslide. Displacement and soil moisture are monitored at a second site located in the southern part of a graben (ARS_GR) in the head of the rockslide. At ARS_WS, instrumentation includes a tipping bucket rain gauge, temperature probe, and a sonic ranging sensor, and at ARS_GR instrumentation includes two cable extension transducers and a soil moisture probe. This data release presents the time series data from this instrumentation for an initial monitoring period starting on November 6, 2013 and ending on December 31, 2018. The data release generally presents the output for each sensor type as recorded on the datalogger, except in one case, for which the output requires conversion to engineering units and the factor necessary to make this conversion is provided. ARS_WS instrumentation Rain gauge: The rain gauge at ARS_WS has a resolution of 0.01 inch (in.) and an accuracy of 1 percent for rainfall intensities up to 2 in/hr. Initially, rainfall was recorded by a Hobo event datalogger and each event was equal to 0.01 in. Beginning on November 18, 2016, 15-minute (min) rainfall totals were recorded by a Campbell Scientific CR1000 datalogger. The rain gauge collector is subject to periodic clogging due to vegetative debris and insect activity. This type of rain gauge is not designed to accurately measure the snow water equivalent of snow fall and likely underestimates precipitation during the winter. Maintenance of the rain gauge is only performed periodically during site visits to retri…
