Passive seismic identifies a meteorite crater in Western Australia
An intriguing presentation given by dr. Jayson Meyers (Resource Potential, Perth, Australia) that illustrates how passive seismic and other geophysical methods identify a young meteorite crater in Archaean greenstone of the Coolgardie Goldfield (Western Australia).
Passive seismic surveying for the quarrying industry
Good quarry design depends upon a ground model that reliably defines the quality, volume and spatial distribution of resource and waste. Most ground models are based on boreholes, sometimes with additional 2D or 3D control provided by ‘traditional’ geophysical surveys such as microgravity, resistivity and active seismic. However, for logistical and economic reasons, these may not always be practical options for site investigations.
A new article published by some authors from the British Geological Survey showcases ‘passive’ seismic survey as a rapid alternative means of imaging the subsurface.
Study of the Kathmandu valley seismic response during the 2015 M7.6 Nepal earthquake
A study of the site amplification in the Kathmandu valley during the 2015 M7.6 Gorkha, Nepal earthquake, has recently been published in the Bulletin of Earthquake Engineering (2016, vol. 14, p. 3301-3315) by Sarah Tallett-Williams et al. The study was performed by using as a main tool a Tromino® donated to the mission by MoHo srl.
The complementarity of H/V and dispersion curves
A new paper has been published on the complementarity of the H/V and dispersion curves, with practical insights (Geophysics, Nov. 2016). Write us (firstname.lastname@example.org) for further information.
Dynamic characterization of the Eiffel Tower
The Eiffel tower is the most visited monument in the world. Millions of visitors have taken millions of pictures of it over the last century but apparently a dynamic picture was not publicly available. In this paper the authors show the amount of information that can be extracted from a few recordings with TROMINO® on the tower, during a visit of pleasure. The original and complete version of this work (in English), which includes the dynamic characterization of the subsurface and other dynamic analysis (earthquakes, wind) of the tower, can be requested directly to the authors.
