Abstract

Pemantauan aktivitas gunungapi dapat dilakukan dengan berbagai metode, dimana salah satunya adalah metode deformasi. Metode ini dapat diimplementasikan menggunakan beragam sensor dan teknik, dimana salah satunya adalah teknik yang menggunakan pengamatan terhadap satelit GPS (Global Positioning System). Makalah ini menjelaskan penggunaan metode survei GPS secara periodik untuk studi deformasi Gunungapi Ijen, gunungapi aktif tipe-A yang terletak di Jawa Timur. Dari hasil survei GPS yang telah dilaksanakan pada Juni 2002, April 2004, Juni 2004 dan Agustus 2005 teramati bahwa pada saat aktivitas gunung Ijen meningkat, pergeseran titik-titik pengamatan dapat mencapai sekitar 1-2 dm, baik dalam komponen horisontal maupun vertikal. Deformasi dalam level ini belum disertai dengan aktivitas letusan dari gunung Ijen.
