A Mw 6.1 earthquake on 25 February 2022, at around 8:39 a.m. local time, struck Pasaman Barat Regency, West Sumatra, Indonesia, and was felt in Singapore Malaysia. The hypocenter of this 12 km deep preceded by an 4.9 foreshock a few minutes earlier. earthquakes originated blind fault triggered landslide Mount Talamau. Herein, the slip distribution asperities along plane during were examined tel...

Penelitian ini bertujuan untuk menganalisa material-material limpasan yang dibawa oleh Gunung Semeru mengetahui gambaran struktur bawah permukaan setelah erupsi tahun 2022. Metode digunakan yaitu metode kualitatif dihasilakan dari pengamatan melalui Oasis Montaj. Mencari nilai bouguer kemudian dipisahkan menjadi anomali regional dan residual menggunakan Filter Butterworth. Hasil pengolahan data...

In the second part of his prize-winning essay 1729, Bouguer (1698–1758) considers a light ray in spherically symmetric medium and introduces invariant named after him. He deduces an expression refraction integral, leading to table which is computed for particular atmospheric model. then studies influence ray’s curvature on horizon dip predicts hillingar effect. As complement, we recall that Bra...

This study investigates the variations of surface Moho inverted from Bouguer gravity data beneath northwestern Arabian plate. The results were obtained by applying 3DINVER program developed in a MATLAB environment using Parker–Oldenburg method. calculation show that maximum depth observed western shield approaches more than 40 km, while minimum values 16–20 km are mainly concentrated Mediterran...

This paper discusses a multivariate approach aimed at geophysical characterization of subsurface rocks for groundwater exploration in arid environments. We integrate several findings obtained from single-source, single-sensor seismic profile with gravity data to detail the tectonic settings and characterize subsurface, water-bearing formations Al Jaww Plain, one most important reserves United A...
