A Tool for Processing and Inversion of MASW Data and a Study of Inter-session Variability of MASW
Geotechnical Testing JournalABSTRACT Multichannel analysis of surface waves (MASW) is a noninvasive active-source technique for determination of near-surface shear wave velocity (VS) profiles. Here we introduce and describe MASWavesPy, an open-source Python package for processing and inverting MASW data, whose design follows an object-oriented paradigm.

Analysis of Liquefaction Potential Based on Seismic Wave Velocity in Bengkulu City
Jurnal Fisika Flux, 2023 Bengkulu City has a high liquefaction rate, both geologically and geophysically. This is because Bengkulu City consists of rocks in the form of sand, silt, mud, clay, coral fragments and gravel in alluvial areas (Qa) and floodplains.

GPS source solution of the 2004 Parkfield earthquake [PDF]
, 2014 We compute a series of finite-source parameter inversions of the fault rupture of the 2004 Parkfield earthquake based on 1 Hz GPS records only. We confirm that some of the co-seismic slip at shallow depth (
