Ocular microtremor (OMT) is a physiological high frequency (up to 150Hz) low amplitude (150-2500nm) involuntary tremor of the human eye. It is one of the three fixational ocular motions described by Adler and Fliegelman in 1934 as well as microsaccades and drift. Clinical OMT investigations to date have used eye-contacting piezoelectric probes or piezoelectric strain gauges. Before contact can ...

Telah dilakukan penelitian mikrozonasi seismik di Desa Nekbaun, Kecamatan Amarasi Barat, Kabupaten Kupang dengan menggunakan metode Horizontal to Vertical Spectral Ratio (HVSR). Penelitian ini bertujuan untuk menentukan nilai indeks kerentanan (Kg) dan percepatan tanah maksimum (PTM), memetakan yang mencakup peta (PTM). Pengukuran mikrotremor Seismometer tiga komponen TDS-303S frekuensi natural...

In the frame of a Belgo-Haitian cooperation project (PIC 2012–2016), study local seismic hazard was performed in Fond Parisien, an area located on foothills “Massif de la Selle”, along easternmost portion Enriquillo Plantain Garden Fault (EPGF). The H/V Spectral Ratio (HVSR) technique applied to resonance frequency target areas and azimuth wave field. amplification factors were estimated using ...
