Measuring sub-mm structural displacements using QDaedalus: a digital clip-on measuring system developed for total stations (2014)
Journal Article
Charalampous, E., Psimoulis, P., Guillaume, S., Spiridonakos, M., Klis, R., Burki, B., …Feltrin, G. (2015). Measuring sub-mm structural displacements using QDaedalus: a digital clip-on measuring system developed for total stations. Applied Geomatics, 7(2), https://doi.org/10.1007/s12518-014-0150-z

The monitoring of rigid structures of modal frequencies greater than 5 Hz and sub-mm displacement is mainly based so far on relative quantities from accelerometers, strain gauges etc. Additionally geodetic techniques such as GPS and Robotic Total Sta...

Long-period surface motion of the multi-patch Mw9.0 Tohoku-Oki earthquake (2014)
Journal Article
Psimoulis, P., Houlie, N., Michel, C., Meindl, M., & Rothacher, M. (2014). Long-period surface motion of the multi-patch Mw9.0 Tohoku-Oki earthquake. Geophysical Journal International, 199(2), https://doi.org/10.1093/gji/ggu302

We show that it is possible to capture the oscillatory ground motion induced by the Tohoku-Oki event for periods ranging from 3 to 100s using Precise Point Positioning (PPP). We find that the ground motions of the sedimentary basins of Japan were lar... Read More about Long-period surface motion of the multi-patch Mw9.0 Tohoku-Oki earthquake.
