“…Microtremor (or ambient vibration) methods analyze the mechanical qualities of the Earth's subsurface, particularly seismic velocities, by measuring background seismic noise. Seismic noise is the constant vibration of the Earth's surface caused by a combination of the low-frequency (less than 1 Hz) natural phenomena (earthquakes, wind, tides, rivers, rain, variations in atmospheric pressure) and high-frequency (greater than 1 Hz) human activities [16,17]. Idriss and Boulanger [18] showed that damage to building structures due to earthquake intensity of ground shocks during an earthquake was significantly influenced by local geological and soil conditions.…”

The high intensity of the earthquake on Lombok Island on 5 August 2018, with a magnitude of 7.0 Mb, caused material losses experienced by the affected residential areas. The Indonesian Geological Agency in 2015 published a microzonation map that mapped zones prone to earthquake shocks to mitigate disasters. This study aimed to compare the level of damage and loss in residential areas due to earthquakes in Mataram City with earthquake-prone zones using a microzonation map. The correlation between damage and loss value of residentials with microzonation maps was evaluated using the overlay method. The results showed that the level of damage and the value of the loss of houses in the high disaster-prone zone (red zone) showed the highest loss value. In comparison, the level of losses in the moderate disaster-prone zone (yellow zone) and light disaster-prone zone (blue zone) on the microzonation map shows a low and lower loss value. This study concludes that the microzonation map helps determine the damage zone and the level of disaster vulnerability caused by the earthquake hazard.

“…This can be seen with the update in the Indonesian seismic code (SNI 1729:2019) with Indonesia's 2017 national seismic hazard maps. Significant accelerations are caused by shallow earthquakes on the coast of West Kalimantan (Syahbana et al, 2021). Based on the explanation above, it can be concluded that the West Kalimantan region is not entirely safe from earthquake hazards, so mitigation is necessary.…”

This paper focuses on the design of a reinforced concrete structure for an eight-story shopping building in Singkawang City, located in a low to moderate seismic area. The study integrates relevant design considerations in response to the region's seismic conditions. Through structural analysis, the building is categorized as seismic design category B due to moderate seismic risk, leading to the selection of an ordinary moment-resisting frame system compliant with SNI 1726:2019. Emphasis is placed on the importance of using such a system to enhance ductility and prevent brittleness during earthquakes.The research emphasizes the need to design structures capable of withstanding various loads, including dead, superimposed dead, live, wind, and earthquake loads, particularly in West Kalimantan, known for its historically low to moderate seismic activity. Recent earthquake records highlight the necessity of earthquake-resistant design for safety and durability. Structural analysis confirms the building's stability against seismic forces, with a modal participation ratio meeting SNI 1726:2019 requirements, indicating robust response under seismic loads.The study also assesses inter-story drift and P-Delta effects to ensure they meet allowable limits, which is crucial for preserving structural integrity and preventing post-earthquake instability. A detailed reinforcement design following SNI 2847:2019 enhances structural strength and durability, especially when under seismic loading. The foundation design uses tailored hollow spun piles to provide sufficient bearing capacity and stability. This approach demonstrates resilience against potential seismic events in low-to-moderate seismic regions, highlighting the importance of integrating seismic design principles and ductility considerations for effective earthquake hazard mitigation.

The Lembang Fault is one of the sources of earthquakes in the Bandung Basin area, Indonesia. Located at coordinates -6.795075°, 107.463449° to -6.865538°, 107.737159° and has a segment length of approximately 29 km, this fault has a potential earthquake hazard that needs to be taken into account. Earthquake hazards originating from its source, namely bedrock, must be analyzed up to the surface. For this reason, a study of the amplification value needs to be carried out. To date, an easy method for analyzing amplification is using the Vs30 approach based on CPTu and geomorphology. This paper aims to obtain amplification values based on the CPTu (electric sondir) and geomorphological methods. This study obtained a 43% agreement, which was indicated by the similarity of the amplification value, which was close to 1. The geomorphology method showed a larger value (more than 1.6). This finding indicates that the equation is used as if it were in an area with a PGA value below 0.1g. Meanwhile, the average value of the two methods is considered relevant, close to 1 or the same as at the earthquake's epicenter. In the future, a more comprehensive method is needed to evaluate the geomorphology equation and the CPTu correlation to the Vs.
