Abstract

Spectral is a basic characteristic that needs to be understood from a volcanic event. This study aims to analyze the spectral and direction of orientation of the source of the volcanic tremor of Ijen volcano. Volcanic tremors are the volcanic events that usually appear before, during and after volcanic eruptions. In 2012 the Ijen volcano showed abnormal conditions, namely the recording of many volcanic tremors with a dissertation on changes in the condition of the lake. This study used secondary data, digital seismic recordings of the Ijen volcano in January-February 2012 (the conditions at Ijen were not normal). Spectral analysis was performed using the Fast Fourier Transform method. Analysis of the direction of source orientation is carried out using the convariance matrix method. The volcanic tremor spectral of Ijen volcano has the characteristics of two frequency peaks with one dominant frequency peak in the range of 1.3-1.5 Hz. The direction of the orientation of the epicenter is towards the Ijen crater and the hypocenter is towards the bottom of the Ijen crater, ranging from a depth of 400-1000 meters. The most appropriate source model to explain the source process of volcanic tremors of Ijen volcano is fluid fill crack.
