Abstract


Sudah 5 Tahun, luapan Lumpur Sidoarjo (LUSI) belum dapat dihentikan. Akibat luapan lumpur tesebut, memicu terjadinya dinamika tanah seperti subsidence dan uplift di sekitar area luapan/semburan LUSI. Pengukuran subsidence dan uplift telah dilakukan pada tahun 2006 hingga 2007 (Abidin, et. al, 2008). Pada tahun 2011 dilakukan pengukuran GPS di sekitar area tanggul penahan LUSI hingga radius sekitar 5 km. Hasil yang diperoleh
