Progress on the earthquake early warning and shakemaps system using low-cost sensors in Taiwan

open access: yesGeoscience Letters, 2022
Building an earthquake early warning (EEW) network requires the installation of seismic instruments around the seismogenic zone. Using low-cost sensors to build a seismic network for EEW and to generate shakemaps is a cost-effective way in the field of ...

Peak Ground Velocities for Seismic Events at Yucca Mountain, Nevada [PDF]

open access: yes, 2005
This report describes a scientific analysis to bound credible horizontal peak ground velocities (PGV) for the repository waste emplacement level at Yucca Mountain. Results are presented as a probability distribution for horizontal PGV to represent uncertainties in the analysis.

Neural Network-Based Equations for Predicting PGA and PGV in Texas, Oklahoma, and Kansas

open access: yes, 2018
Parts of Texas, Oklahoma, and Kansas have experienced increased rates of seismicity in recent years, providing new datasets of earthquake recordings to develop ground motion prediction models for this particular region of the Central and Eastern North ...

The effects of walking speed on minimum toe clearance and on the temporal relationship between minimum clearance and peak swing-foot velocity in unilateral trans-tibial amputees [PDF]

open access: yes, 2015
yesBackground: Minimum toe clearance is a critical gait event because it coincides with peak forward velocity of the swing foot, and thus, there is an increased risk of tripping and falling.

An updated 1-dimensional seismic velocity model has been developed for the Mw 6.1 Pasaman earthquake that occurred on February 25, 2022

open access: yesJournal of Applied Geospatial Information
On February 25, 2022, a strong-felt earthquake with magnitude Mw 6.1 occured within the western portion of Pasaman, West Sumatra, Indonesia. The impact of the seismic activities has produced an enormous shaking which measured as VI on the Adjusted ...

New constraints for site-effect characterization from seismic noise analysis in southern Italy. San Fele case study

open access: yesAnnals of Geophysics, 2010
In the framework of ground-motion amplification analysis for southern Italy, the main target of this study is to provide new constraints on one-dimensional, shallow-velocity profiles for a site in the San Fele area near the city of Potenza (southern ...

Ground-State SiO Maser Emission Toward Evolved Stars

open access: yes, 2004
We have made the first unambiguous detection of vibrational ground-state maser emission from SiO toward six evolved stars. Using the Very Large Array, we simultaneously observed the v=0, J=1-0, 43.4-GHz, ground-state and the v=1, J=1-0, 43.1-GHz, first ...

Effects of Topography on Seismic-Wave Propagation: An Example from Northern Taiwan [PDF]

open access: yes, 2009
Topography influences ground motion and, in general, increases the amplitude of shaking at mountain tops and ridges, whereas valleys have reduced ground motions, as is observed from data recorded during and after real earthquakes and from numerical ...
