Abstract

Abstract : Banda Aceh is located at the geological segment vulnerable to earthquake. However as the capital of the Aceh province should be a serious concern in order to minimize the impact of the devastating earthquake. Therefore, the assessment of soil layer amplification using shear wave velocity values is done as one of the disaster mitigation efforts. Shallow seismic testing to get the parameters of shear wave by using MASW method. The results showed that Syiah Kuala subdistrict is divided into two zones of soil layers. The results of analysis Vs30 showed that Syiah Kuala subdistrict is divided into medium density and soft layers of soil characteristics.Keywords : earthquake, amplification, seismic and shear wave.Abstrak: Kota Banda Aceh terletak pada segmen geologi yang rentan gempa bumi. Bagaimanapun Banda Aceh sebagai pusat kota Provinsi Aceh semestinya menjadi perhatian serius dalam rangka meminimalisir dampak dari bencana gempa bumi. Oleh karena itu, asesmen karateristik amplifikasi lapisan tanah dengan menggunakan nilai kecepatan gelombang geser dilakukan sebagai salah satu bentuk upaya mitigasi bencana. Penelitian dilakukan di Kecamatan Syiah Kuala, Banda Aceh. Pengujian seismik dangkal untuk mendapatkan parameter gelombang geser dengan mengunakan metode MASW. Hasil analisis Vs30 memperlihatkan bahwa Kecamatan Syiah Kuala terbagi menjadi dua karakteristik lapisan tanah yaitu kepadatan sedang dan lunak.Kata kunci : gempa bumi, amplifikasi, seismik dan gelombang geser.

Abstract

Earthquake on July 2, 2013, destroyed several buildings in Aceh Tengah district and Bener Meriah district of Aceh Province. This earthquake gives Aceh government a clue that the seismic hazard map must become the reference in development plan in future. To respond this idea, we conduct the research and try to estimate the amplification factor for developing seismic hazard maps of those districts. This study aims to determine the average shear wave velocity up to the depth of 30 meters (Vs30) and the amplification factor of Aceh Tengah district and Bener Meriah district, to build the seismic hazard map of both districts. In this study, we use the MASW (Multi-Channel Analysis of Surface Waves) with 24 geophones in the frequency of 10 Hz at 10 locations to determine the Vs30 beneath the surface. The soil and rock classification from ASCE 2010 and SNI 1726:2012 used to classify the soil/rock based on Vs30 and calculate the predicted amplification factor using the Borcherdt Eeri equation. The result of this study reveals that the range of Vs30 in the study area is 76 m/s 308 m/s. The loosest sediment has 76 m/s located at point 2 in Aceh Tengah district. The shear wave velocity of 76 m/s classifies as soft soil (SE). Based on the calculation, the pyroclastic deposit and sediment in the basin of the study area will be amplified the seismic wave in the range of 2.9 to 3.3 times. In the future, we suggest conducting another geophysical survey to determine the correct amplification factor to improve the quality of seismic hazard map.
