Spatial Analysis of Seismic Hazard Based on Dynamical Characteristics of Soil in Kota Baru, South Lampung [PDF]

, 2019
Kota Baru, a new capital Lampung province location, planned and developed since 2012, will be a densely populated in near time. The province located in near Semangko fault, southern of Sumatra Island, is a vulnerable area to earthquake.

Microtremor recording techniques

Bulletin of the New Zealand Society for Earthquake Engineering, 1973
For some years seismologists and engineers have been recording and measuring microtremors. In this paper a review of earlier micotremor investigations is presented and microtremor recording apparatus developed at Auckland University Engineering School is described. Two distinct methods of recording have been developed. One uses a conventional low-cost

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

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.

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.

Vertical‐Component Seismic Response and System Identification of a 52‐Story High‐Rise Building Using Earthquake Data

Earthquake Spectra, Volume 42, Issue 2, May 2026.
This study investigates the vertical dynamic response of a 52‐story high‐rise building in downtown Los Angeles using small‐magnitude earthquake data recorded by the Community Seismic Network. While seismic design traditionally emphasizes horizontal ground motion, vertical accelerations can have a significant impact on tall structures, leading to ...

Evaluating Seismic Ambient Noise Techniques for Imaging Lava Tubes on the Moon

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Detecting and characterizing lava tubes is a key objective of upcoming lunar missions. While evidence for their presence exists, their precise dimensions and depths remain uncertain. This study evaluates the potential of seismic ambient noise methods, such as seismic interferometry, H/V spectral ratios, distributed acoustic sensing (DAS), and ...

Seismic Site Effects in Owhiro Bay Quarry, Wellington: Field Observations and Numerical Modelling

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Local topography and geology are well known factors affecting the intensity of seismic shaking. We have investigated the seismic site effects at a site of the Owhiro Bay Quarry in Wellington, New Zealand, using instrumental records and numerical models.
