“…Previous research has shown sparsely vegetated areas are more prone to landslides (Aviva and Setiawan, 2022). The existence of forests can stabilize landslide-prone areas (Ivanik et al, 2021). Another study reported that landslide intensity is lower in forests than in open land.…”

One of the efforts to manage the risk of ground movement is to identify landslide-prone area characteristics. This study aimed to investigate the geophysical, geotechnical, and vegetation characteristics of landslide and non-landslide areas. This study adopted the resistivity geoelectric method to identify the type and structure of subsurface materials in landslide and non-landslide regions in Pujon and Ngantang, Malang Regency. Measurements in this study were done in four locations. Each geoelectric measurement path at each location was determined to be 100 m long. The electrodes were spaced apart by 10 m for measurements between the current electrode and the potential electrode. The dipole-dipole configuration of the geoelectric survey trajectory is determined based on the former landslide event to predict underground material. In addition, an investigation of geological, geotechnical, and vegetation characteristics was carried out. The results showed that the geophysical, soil, and vegetation characteristics of the landslide and non-landslide slopes were similar. The geophysical characteristics of the soil in all study locations indicate the presence of a slipping surface, which makes the land prone to landslides. The slipping plane was formed due to differences in the types of rocks between the surface and deep layers. The existence of vegetation has an important role in landslide management. Non-landslide areas tended to have denser tree vegetation and a higher number of shrub species.

“…After irradiation with a dose D γ ≈ 5×10 3 Gy, the IF maximum height at T M1 ≈ 330 K (Fig. 4) did not change significantly in comparison with the IF Q -1 (T) spectrum before irradiation, indicating a special effect of the dose D γ ≈ 5×10 3 Gy.…”

“…Among the methods for studying structural defects in these crystals, the structure-sensitive IF method is promising, making it possible to study dislocation dynamics (2). A structurally sensitive mechanical relaxation IF method was used to study the presence and dynamics of the structural defects (3,4). Mechanical relaxation of the elastic deformed semiconductor crystal manifests as an Internal Friction, Mechanical Spectroscopy in SiO2/Si Wafers Y.…”

In this work, after X-ray and electron irradiation, the outcomes of the evaluation dynamic characteristics of interstitial atoms Sij , vacancy V, and O-complexes were evaluated to account for the annealing conditions to derive specific structural defects in the SiO2/Si wafer. A non-destructive method, which allows the determination of the internal friction difference ΔQ-1/Q-1 0 of the elastic vibration structure defect density Nd and the depth of the broken layer hb , is offered for the SiO2/Si wafer. The method was developed, the installation was designed and manufactured for the excitation and registration of damped bending resonant oscillations in a SiO2/Si disc-shaped wafer with a thickness hSiO2 ≈ 100 nm, his = 300÷500×103 nm, and diameter D = 60÷100×10-3 m to measure the structurally sensitive internal friction Q-1 . Measurement of the internal friction background Q-1 0 at harmonic frequencies f0 and f2 allowed us to experimentally determine the nodal lines of the oscillating disks.
