Seismic site characterization of the Kastelli (Kissamos) Basin in northwest Crete (Greece): Assessments using ambient noise recordings [PDF]

, 2014
Crete is actively seismic and site response studies are needed for estimating local site conditions subjected to seismic activity. In order to collect basic data, we performed ambient noise recordings to estimate the site response of the surface and near

Microtremor coherency

Bulletin of the New Zealand Society for Earthquake Engineering, 2010
By recording microtremors simultaneously using arrays having two apertures, the effect of incoherent noise, which can act to depress coherency values, may be reduced, leading to better estimates of azimuthally-averaged coherency, and hence to improved shear-wave velocity profiles at sites.

An integrated geophysical approach for investigating hydro-geological characteristics of a debris landslide in the Wenchuan Earthquake area [PDF]

, 2017
Debris landslides are one of the most widely distributed types of landslides in the Wenchuan earthquake area. The hydro-geological structure characteristics are the fundamental basis for stability evaluation, performing protection and administration of a

Simultaneous recordings of ocular microtremor and microsaccades with a piezoelectric sensor and a video-oculography system [PDF]

, 2013
Our eyes are in continuous motion. Even when we attempt to fix our gaze, we produce so called “fixational eye movements”, which include microsaccades, drift, and ocular microtremor (OMT).

Existing motor state is favored at the expense of new movement during 13-35 Hz oscillatory synchrony in the human corticospinal system [PDF]

, 2005
Oscillations in local field potentials in the β-frequency band (13-35 Hz) are a pervasive feature of human and nonhuman primate motor cortical areas. However, the function of such synchronous activity across populations of neurons remains unknown.

Site amplification in the Kathmandu Valley during the 2015 M7.6 Gorkha, Nepal earthquake [PDF]

, 2016
The 25th April 2015 M7.6 Gorkha earthquake caused significant damage to buildings and infrastructure in both Kathmandu and surrounding areas as well as triggering numerous, large landslides. This resulted in the loss of approximately 8600 lives.

Shallow Shear‐Wave Reflection Surveys in the Wellington Central Business District

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Seismic reflection profiling using shear waves provides constraints on the thickness of sediments beneath the Wellington Central Business District. Standard seismic methods were modified for urban environments where limited grassed areas are available and levels of cultural noise are high.
