Abstract

Spring is a natural phenomenon that is commonly found on the slopes of a volcano. Springs appearance in Mt. Merapi are controlled by the local geological conditions, including geomorphology, lithology and geological structure. This research carried out by hidrogeological survey of several springs at southern slope area of Merapi Mt. before eruption, combined with secondary data of springs after eruption. Sampling have been taken together with hydrogeological survey by collecting data of hydrogeological characteristics such as aquifers condition and hydrochemical of springs.
The condition of existing springs in this area are also influenced by the eruption activities of Mt. Merapi. Changes in quantity and quality due to a fairly powerful eruption activities for approximately one month since October 26th, 2010. Some springs in the vicinity of Mt. Merapi still produce, although they reduce the discharge. There is Umbul Lanang spring that showed increasing of discharge. However, in general, many springs damaged and even do not produce water any more since buried by volcanic materials. Most of the pipelines do not function because of twofold; the volcanic materials broke or mud clogged them. Some of the pipe was totally destroyed by volcanic materials, or by hitting of cold lahars of Merapi.
