Abstract

This study aims to determine the seismic vulnerability index using microtremor data in Parigi City. A microtremor survey was conducted at 81 sites across the city. The data were analyzed to obtain the Horizontal to Vertical Spectral Ratio (HVSR) curve and the Rayleigh wave ellipticity curve. These two curves were combined to derive the dominant frequency (f₀) and amplification factor (A₀). The Rayleigh wave ellipticity curve was used to guide the determination of the dominant frequency (f₀) and amplification factor (A₀) on the HVSR curve. The results were then used to calculate the seismic vulnerability index (Kg). The peak of the Rayleigh wave ellipticity curve (Aₑₗₗ) can assist in identifying the dominant frequency (f₀), both when the A₀ peak is clearly visible (clear peak) and when there are multiple or unclear peaks. The use of Aₑₗₗ also helps refine the determination of A₀ values, yielding more stable results. The final mapping results show that the dominant frequency values range from 0.26 Hz to 2.9 Hz, the amplification factor ranges from 1.61 to 4.77, and the seismic vulnerability index ranges from 1.47 to 113.59. Conclusion, The integration of the HVSR curve and the Rayleigh wave ellipticity curve carried out in this study shows that both can be combined and complement each other.   Keywords: Dominant Frequency (f0), Amplification Factor (A0), Seismic Vulnerability Index (Kg), Rayleigh Wave Ellipticity Curve, Horizontal-to-Vertical Spectral Ratio (HVSR) Curve

Abstract

Kalisalak Hamlet in Sukoharjo District is faced with the risk of landslides that can affect the structure of residents' houses. This study aims to identify potential landslide zones based on the parameters of Dominant Frequency (f_0), Amplification Factor (A_0), and Seismic Vulnerability (K_g)to determine areas that are potentially vulnerable to landslides. Microseismic measurements were carried out at 25 measurement points in the landslide zone. Measurements used a 3-component digital portable seismograph (North-South, West-East, and Vertical). Microseismic data were processed using Geopsy software with the HVSR (Horizontal-to-Vertical Spectral Ratio) method to obtain an H/V curve that provides Dominant Frequency (f_0) and Amplification Factor (A_0) values. The results showed that Kalisalak Village has a dominant frequency value between 3 Hz to 12.5 Hz and an amplification factor value between 1.4 to 6.8. This variation indicates that some areas are more susceptible to seismic vibration amplification. Based on the Dominant Frequency (f_0) value and Amplification Factor (A_0), a Seismic Vulnerability (K_g) microzonation map was created for Kalisalak hamlet with a value range of 0.2 to 7 with a high vulnerability value located in the landslide area south of the village. This map is important for disaster mitigation planning in Kalisalak hamlet.

Abstract

The Yogyakarta region is prone to frequent earthquakes, highlighting the need for seismic vulnerability assessment and micro zonation analysis. This study aimed to evaluate the area's seismic vulnerability by utilizing microtremor methods to estimate dominant frequency, amplification, seismic vulnerability index, and shear wave velocity. Microtremor points were analyzed using the Horizontal Vertical Spectral Ratio method, with data processed through Geopsy software to obtain f0, A0, and H/V curves. The H/V curve was further inverted using Dinver software to derive ellipticity curves, ground profiles, and Kg values. The results revealed that the dominant frequency values ranged from 0.668 Hz to 18.271 Hz, with higher values prevalent. The soil types in the area were classified as type IV and type I, primarily consisting of older, hard sandy rocks and gravels. Amplification values ranged from 1.03 to 8.36, indicating low amplification levels and placing the area in zone 1. Kg values varied from 0.066 to 15.07 s²/cm, suggesting moderate seismic vulnerability. If an earthquake occurs, the region would experience shaking, though damage would be moderate. Vs30 values ranged from 179.64 m/s to 681.82 m/s, categorizing the soil as hard, dense, soft, or medium.

Abstract

The shear wave velocity (Vs) is a crucial parameter for determining subsurface layers by averaging the Vs value to a depth of 30 meters, known as Vs30. This study aims to analyze the subsurface soil layers, calculate the Vs30 value, and assess the potential seismic site classifications in Kapanewon Prambanan and its surrounding areas. The research utilizes secondary microtremor data from 27 observation points in the form of MSD files. The microtremor data was processed using Geopsy software with the HVSR method to generate an H/V curve. This curve was further analyzed with the Ellipticity Curve method via Dinver software to obtain the Vs profile at various depths. The findings suggest that the subsurface layers in Kapanewon Prambanan are predominantly composed of hard, very dense soil, soft rocks, and solid rocks, based on the Vs30 values. The Vs30 distribution across the region ranges from 267.857 m/s to 1675.977 m/s, classified into site categories A, B, C, and D. However, the majority of the area falls under site classes B and C. These classifications indicate that the regions under B and C have a relatively lower potential for significant earthquake wave amplification. Nonetheless, attention should still be given to areas categorized under sites D and E, particularly for earthquake disaster mitigation efforts. This detailed Vs30 analysis provides critical insights for seismic assessments, regional planning, and mitigation strategies in Kapanewon Prambanan.

Abstract

The southern Java subduction zone is one of the major tsunami hazard sources in Indonesia due to its potential to generate large megathrust earthquakes. This study evaluates tsunami hazards from a Mw 8.7 megathrust earthquake scenario using numerical modelling with COMCOT v1.7. A five-layer nested grid system is applied to simulate tsunami generation, propagation, and inundation from the Indian Ocean to the Pancer - Puger coast, Jember Regency, Indonesia. Earthquake source parameters are defined using the Wells and Coppersmith empirical relationships, while initial seafloor deformation is calculated using the Okada elastic dislocation model. Tsunami wave dynamics are analysed using Virtual Tsunami Gauges (VTGs). The results indicate that Puger Kulon and Mojosari villages experience the most severe impacts, with large wave amplitudes, strong currents, and inundation exceeding 20 m depths. Tsunami arrival times is about 21 to 27 minutes, providing a very limited evacuation window. The ETH (Estimated Tsunami Height) and ETA (Estimated Time of Arrival) maps show that low-lying, open coastal plains act as primary pathways for tsunami penetration. These findings emphasize the high vulnerability of the Pancer coast - Puger and the need for risk-based mitigation, improved evacuation planning, and strengthened local early warning systems.Keywords: tsunami; COMCOT; Pancer coast; inundation; arrival time
