Open AccessDiscrimination between earthquakes and quarry blasts in the Aswan region, southern Egypt, using P-wave source spectra
In order to distinguish between shallow earthquakes and quarrying activity, we evaluated 3069 seismic signals from 413 occurrences (112 explosions and 301 shallow earthquakes, depths 5 km), collected by the As...

Open AccessStrong motion estimation in Costa Rica at non-record sites using spectral inversion method
We performed the spectral inversion to separate the source, path, and site effects using strong ground motion records from essential facilities such as powerhouses and hydroelectric dams, distributed all over ...

Open AccessAn assessment of uncertainties in VS profiles obtained from microtremor observations in the phased 2018 COSMOS blind trials
Site response is a critical consideration when assessing earthquake hazards. Site characterization is key to understanding site effects as influenced by seismic site conditions of the local geology. Thus, a nu...

Open AccessIncrement in the volcanic unrest and number of eruptions after the 2012 large earthquakes sequence in Central America
Understanding the relationship cause/effect between tectonic earthquakes and volcanic eruptions is a striking topic in Earth Sciences. Volcanoes erupt with variable reaction times as a consequence of the impac...

Open AccessEarthquake early warning: what does “seconds before a strong hit” mean?
An earthquake early warning (EEW) system is designed to detect an event, determine its parameters (hypocenter, magnitude, and origin time), and issue an alert to sites/areas where necessary actions should be t...

Open AccessSubsurface velocity structure and site amplification characteristics in Mashiki Town, Kumamoto Prefecture, Japan, inferred from microtremor and aftershock recordings of the 2016 Kumamoto earthquakes
In order to investigate the seismic velocity structure in the region of concentrated severe damage during the 2016 Kumamoto earthquake sequence, we conducted continuous seismic observations in the central area...

Open AccessBuilding damage survey and microtremor measurements for the source region of the 2015 Gorkha, Nepal, earthquake
We performed a damage survey of buildings and carried out microtremor observations in the source region of the 2015 Gorkha earthquake. Our survey area spans the Kathmandu valley and areas to the east and north...

Open AccessEstablishing a reference rock site for the site effect study in and around the Kathmandu valley, Nepal
We propose a reference site for the site effect study in and around the Kathmandu valley, Nepal. The used data were the accelerograms recorded at two stations, DMG and KKA, and velocity seismograms co-recorde...

Open AccessCalibration of amplification factors using KiK-net strong-motion records: toward site effective estimation of seismic intensities
Estimated seismic intensities using conventional relationships are not always in agreement with those observed at specific sites. We investigate subsurface amplification factors using the KiK-net strong-motion...
