Abstract: Case studies of regional landfills show that electromagnetic geophysical methods can accurately and inexpensively define boundaries and thickness of waste. Degradation of putrescible solid waste generates conductive leachate that can be imaged with a frequency-domain terrain conductivity meter. Terrain conductivity measurements can be modified through a simple algorithm based upon ...
Passive seismic exploration methodology, in particular the IPSS/IPDS (Infrasonic Passive Seismic Spectroscopy/ Infrasonic Passive Differential Spectroscopy ) and PST/MST (Passive Seismic ...
This is an update to their 2016 forecast and the second year both types of hazards are forecasted, as previous USGS maps only identified hazards from natural earthquakes. The new report is valuable for making more informed decisions to reduce the ...

Geovista manufactures monitoring geophones for use with long term seismic recording in shallow wells. A three axis geophone is lowered into a shallow well and analogue measurements are measured over time. These geophones are generally deployed as part of a field array of geophones connected to a central database for long term monitoring. Please contact us for more information.
