Abstract
Pada tahun 2006, terjadi erupsi Gunung Merapi yang terletak di Jawa Tengah. Sebagaimana diketahui, Merapi termasuk gunungapi teraktif di dunia, dicirikan oleh tipe erupsinya yang spesifik, yaitu pembentukan kubah lava, disusul dengan guguran lava membentuk aliran piroklastika dan awan panas. Aliran piroklastika cukup besar terjadi pada tanggal 14 Juni, mencapai jarak 7 km kearah tenggara. Sebuah obyek wisata, Kaliadem di Kecamatan cangkringan terkubur endapan piroklastik setebal lebih dari 3 m rata-rata. Dua relawan terpanggang di dalam bunker. Kegiatan Merapi selanjutnya diikuti oleh banjir lahar. Dampak hidrogeologis dari aktivitas Merapi tersebut antara lain beberapa mata-air lenyap, dan komposisi airtanah mengalami perubahan, namun demikian distribusi muka airtanah dan arah alirannya secara umum relatif tidak mengalami gangguan. Kata Kunci: Gunung Merapi, erupsi, awan panas, lahar, airtanah ABSTRACT: In the year 2006, Mount Merapi that is located in the Central Java erupted. As we may know, Merapi belongs to one of the most active volcanoes on the world, it is characterized by a very specific type of eruption, i.e. lava dome development, following by lava collapse forming flow pyroclastics and glowing clouds. Such a great flow pyroclastics occurred on 14th June, reaching 7 km distant to the southeast direction. A tourist object, namely Kaliadem, in the Cangkringan District was buried by pyroclastic deposits more than 3 m thick in average. Two volunteers were assassinated in the bunker. Activity of Merapi was then followed by lahar flooding. There were hydrogeologic impact of Merapi activities to the surrounding areas.Some springs disappeared, and groundwater composition changed, but the groundwater table distribution and its flow direction relatively have not disturbed. Key words: Mount Merapi, eruption, nuee ardentes, lahar, groundwater
