Investigasi Kerentanan Tanah Berpotensi Likuifikasi Menggunakan Metode Mikroseismik Di Wilayah Prambanan, Yogyakarta

Abstract: <p>Metode mikroseismik merupakan suatu metode pasif seismik yang menggunakan sumber pasif bumi. Metode ini dapat digunakan untuk menganalisis potensi efek kerentanan tanah di sekitar wilayah Prambanan, Yogyakarta, Indonesia. Studi kali ini berlandaskan pada teori gempa bumi yang dapat memicu mengaktifkan bahaya lain seperti likuifaksi yang disebabkan karena tanah kehilangan kekuatan akibat kehilangan tegangan yang berasal dari pori batuan yang terisi oleh fluida. Dengan demikian, informasi tentang potens… Show more

“…Potential vulnerability of the soil can be investigated by analyzing vertical (SV) and horizontal (SH) waves from a micro seismic or tremor phenomenon from natural waves generated by the earth. the presence of liquefaction potential soil vulnerability will be influenced by the value of seismic vulnerability (SVI), earthquake frequency, amplification and ground acceleration (peak ground acceleration [10].…”

“…Seismic susceptibility is an index that shows the level of susceptibility of the surface layer to deformation during an earthquake [4]. Seismic susceptibility microzonation map can be used as a reference for urban development and planning [12]. The seismic susceptibility is directly proportional to the amplification value and inversely proportional to the dominant frequency value, as shown in equation 2.1.…”

“…Sedangkan untuk daerah yang berwarna biru hingga merah dengan rentang frekuensi natural sekitar 7-18 Hz memiliki klasifi kasi tanah yang lebih keras dengan ketebalan lapisan sedimen permukaannya lebih tipis dibandingkan dengan daerah berwarna ungu. Adapun frekuensi natural gempa menurut teori Nakamura adalah sekitar 5-15 Hz (Aditama, Saadi, & Nurcahya, 2020). Nakamura menjelaskan bahwa f 0 saling berkaitan dengan kedalaman batuan dasar.…”
