“…The variety of soil characteristics each produce their own unique set of velocity values for shear waves in the soil matrix. As a result, it is possible to connect it with various aspects of the soil, and it is also possible to use it as a crucial variable in usages such as the identification of the soil and the evaluation of its technical behavior [52].…”

The Central Bengkulu Regency possesses a coastline measuring 21.8 km, situated in direct proximity to the Indian Ocean. The heightened wave and ocean current dynamics possess the capacity to induce detrimental effects in the form of coastal abrasion along the coastline. This study conducted an examination of the rate of shoreline changes resulting from coastal abrasion in Central Bengkulu Regency, Bengkulu, Indonesia. Horizontal-to-vertical spectral ratio (HVSR) analysis, multichannel analysis of surface waves (MASW), and Landsat-8 remote sensing were all used in the current investigation. The project gets started with conducting field investigations and measurements of geophysical techniques, including the collection of Landsat-8 satellite imagery spanning the period from 1990 to 2020. Additionally, an examination was conducted on the rate at which the shoreline undergoes changes in velocity. In order to determine the increase in change that occurs along coastlines over a period of several decades, a study was carried out during which Landsat-8 satellite images were analyzed. This study investigates the application of the HVSR technique for assessing the seismic vulnerability of the ground and, additionally, the MASW technique for measuring the shear wave velocity of the coastline’s soil. Both of these methodologies are compared and contrasted with one another in this research. The findings indicated that the mean pace of coastline change in Central Bengkulu Regency was 1.5 m/yr, with the maximum velocity recorded at 4.1 m/yr. This high velocity of shoreline change is correlated with the Vs30 value of MASW measurement and Kg of HVSR measurement, where the subsurface soil structure along the coast of Central Bengkulu Regency from Vs30 measurement shows that it is dominated by stiff soil structure that is susceptible to erosion. Outcomes from the study can inform decision-making processes about safeguards and preventative measures to prevent further coastal degradation. HIGHLIGHTS In this paper, we present a framework using application passive and active seismic method with Landsat 8 for knowing the changing of shoreline coastal area in Central Bengkulu Indonesia This study demonstrated that the high velocity of the shifting shoreline is correlated with Vs30 and Kg values The subsurface soil structure is predominantly composed of stiff soil, and the changing shoreline starts at 1.5 mm/yr, which makes the coast of Central Bengkulu vulnerable to erosion GRAPHICAL ABSTRACT

“…Unfortunately, it has been shown that different forms of the correlation equations have been devel oped in different areas. It appears that local correl ations are necessary for satisfactory use of the technique as demonstrated for example by L'Heureux and , Duan et al (2019) or Elbeggo et al (2021). In this paper data for clays in eastern Canada will be examined and compared with similar clays in Norway and southern Sweden.…”

The purpose of this paper is to encourage the use of the seismic cone penetrometer (SCPTU) in soil characterisation studies. There has been an increase in use of shear wave velocity (V s ) data in geotech nical engineering. This has been prompted by improvements in measurement and analytical systems. A significant advantage, as is confirmed here, is that V s can be measured easily and repeatedly by several different techniques in the sensitive marine clays under consideration here. Here the focus is on the derivation of preconsolidation stress (p c ') from V s . A rational method of determining a V s /p c ' relationship is outlined with resorting to empirical data analysis. The proposed relationship is shown to work well for Canadian sensi tive clay data as has been shown previously for Norwegian and Swedish clays

“…Vs is considered a reliable parameter, more than Vp, for the definition of mechanical properties and behavior of soil materials. In various studies, Vs was taken into relation to cone penetration resistance [1][2][3][4][5][6], general geotechnical parameters [7][8][9][10][11][12], rock quality [13][14][15], liquefaction, and unsaturated soil densification [16][17][18][19][20][21][22][23][24] as well as, groundwater or hydrocarbon detection by combining Vs with Vp [25].…”

This contribution introduces a computerized semi-automated procedure coupled with a dedicated algorithm to improve shear wave velocity assessment and the on-site elastic damping ratio estimation of ground materials. The standard equipment of the downhole method is integrated with a horizontal geophone (guardian) placed on the field surface. Mask tapering and band multi-filter functions improve first arrival, recognizing and isolating SH-wave trains to estimate damping ratio profiles. These are computed by treating signals using a frequency–time combined approach (frequency–time packets method). The signals are corrected to consider the different source pulse amplitude, the effects of the propagation path, and scattering. The damping ratio profile is statistically computed in terms of the local drift of trend on the amplitude ratio series that would otherwise have a normal distribution centered on zero. These profiles intercept the lithology changes in the test sites and meet the damping values stemming from previous field tests and the laboratory experimental tests available in the literature regarding materials such as the ones investigated here.
