...Furthermore, the additional integration with geological and borehole information is useful for the improvement of the geophysical data interpretation, overcoming the non-uniqueness typical of the geophysical model obtained (McCann and Forster, 1990; Loke et al., 2013)....

...Loke et al. (2013) have highlighted and discussed the major ERT limitations among which, as also pointed out in the papers analyzed, themost important in landslide application are: the non-uniqueness of solution, the investigation depth and resolution, the calibration of data, the three-dimensional…...

...(a) The results from calculating changes in relative surface-wave velocity over time via cross correlation of ambient noise seismic records by Mainsant et al. (2012). Decreases in velocity by 2% develop over 20 days (1), before a total decrease of 7% is observed (2) in the seven days preceding a significant failure (shaded gray area). (b) The cross-correlation coefficient and (c) the daily and cumulative rainfall. From Mainsant et al. (2012). Copyright © 2012 by John Wiley & Sons, Inc....

...Non-polarizable electrodes (Reynolds, 2011) are widely used as the potential electrodes in I.P. surveys to reduce SP noise, although there has been recent progress in using conventional metal electrodes (Dahlin and Leroux, 2012) which aremore convenient to use with multi-electrode systems....

...One common form of the roughness filter is the first-order difference matrix (deGroot-Hedlin and Constable, 1990), but the elements of the matrices can be modified to introduce other desired characteristics into the inversion model (Farquharson, 2008; Pellerin and Wannamaker, 2005)....
