Abstract
Gunung guntur merupakan salah satu gunung aktif di Indonesia dengan tipe gunung api strato volcano dan memiliki status kegempaan gunung api yang cukup tinggi. Beberapa kajian penelitian tentang Estimasi Centroid Moment Tensor (CMT) sudah banyak diterapkan untuk monitoring status gempa vulkanik. Akuisisi data di sekitar kawasan gunung Guntur dan data rekaman sebelumnya sangat mendukung dalam penelitian ini dalam proses pemilihan data. Pengolahan menggunakan software GAD untuk relokasi gempa dan ISOLA MATLAB-GUI untuk membuat pola sebaran (focal mechanism) gempa vulkanik pada sekitar gunung Guntur. Dari ketujuh event gempa lima event memiliki nilai DC dominan yaitu 72.8% sampai 96.1%, sedangkan untuk event lainnya mempunyai presentase non-DC dominan mulai dari 51.1% sampai 94%. Gempa Vulkanik yang terjadi di Gunung Guntur berkaitan dengan aktivitas vulkanik yang menimbulkan gaya yang bekerja pada medium batuan. Penelitian ini diharapkan dapat memberikan gambaran pola sebaran gempa vulkanik dan model focal mechanism untuk mengetahui bidang patahan dan monitoring tingkat kegempaan pada gunung Guntur. Selanjutnya dari penelitian ini dapat dimanfaatkan dalam pengembangan penelitian untuk studi kasus di sekitar gunung Guntur.
===========================================================================================================
Guntur mountain is one of the active volcanoes in Indonesia with a new type of strato volcano. Guntur Mountain have an active in the status of the volcano seismicity. Several research studies on Estimation Centroid Moment Tensor (CMT) has been widely applied for status monitoring volcanic earthquakes in the world. Data acquisition around the Gunutr Mountain and previously recorded data is strongly support for this research in the processing data. GAD software for relocation of the earthquake and ISOLA MATLAB-GUI Software to make the distribution pattern (focal mechanism) of volcanic earthquakes around Guntur mountain. The seventh event of an earthquake five events have a dominant DC value that is 72.8% to 96.1%, another event has a non-DC dominant have percentage ranging from 51.1% to 94%. Volcanic Earthquake that occurred on Guntur Mountain related to the volcanic activity that give rise to forces act on the rock medium. This research is expected to describe the distribution pattern of volcanic earthquake focal mechanisms and models to determine fault areas and seismicity level monitoring in the Guntur Mountain. Furthermore, from this study can be utilized in the next research for the development with case studies around Guntur Mountain.
