Article history: Received 4 July 2015 Received in revised form 4 December 2015 Accepted 10 December 2015 Available online 11 December 2015 This paper presents the time history maps of horizontal-to-vertical spectral ratio (HVSR) of 12 long-term microtremor recordings (LTRs) in Northern Mississippi and the coastal area of Gulf of Mexico. These maps show that a stable predominant frequency (f0) v...

Microtremor measurements and the horizontal-to-vertical spectral ratio (HVSR) technique, generally used for site effect studies as well as to determine the thickness of soft sedimentary layers, can effectively be applied to map the thickness of glaciers. In this work the radio-echo sounding, geoelectric and active seismic methods, widely employed to image the earth interior, are applied to veri...

Ljubljana, the capital of Slovenia, is located in the central region of the country in a shallow sedimentary basin filled with Quaternary deposits. It is one of the most seismically active regions in Slovenia, with some important historical earthquakes that have caused damage and economic losses. The soft sediments are some of the most important factors responsible for the amplification of seis...

Microtremor is ambient vibration on the surface ground by natural phenomena, human activities, etc. data can be processed using various software such as Geopsy, easyHVSR, and MATLAB. Another alternative to process microtremor Scilab. This research was conducted classify soil HVSR methods Scilab 6.1.0. in Sendangmulyo, Semarang. Data processing includes generating synthetic signals, coding Scila...

Bandung basin is surrounded by active volcanoes at the center of Western Java region. Soil type this area consists mostly volcanic alluvial, formed past activities. At location, we performed passive seismic surveys to reveal sedimentary characteristics using a triaxial seismometer, study properties which have potential implications on environmental aspects, such as natural disaster mitigation a...

SUMMARY The stability of the low-frequency peaks (<1 Hz) obtained in passive seismic survey Campo de Dalías basin (CDB) by applying horizontal-to-vertical spectral ratio (HVSR) method was investigated. Three temporary stations were installed remote sites that enabled studying stationarity their characteristic microtremor HVSR (MHVSR) shapes. All began to operate mid-2016 and recorded at ...
