“…Most of the explosion waveform characteristics are similar in our analysis. This characteristic is similar to the explosion waveform at different volcanoes [16]. The dominant frequency of explosion is approximately 1-5 Hz (see Figure 3b).…”

We investigated the distribution between the magnitude and corner frequency of explosion earthquakes at the Anak Krakatau volcano during June - July 2014. We analyzed 100 explosion waveforms recorded at the KRA3 and KRA4 seismic stations located approximately 0.55 km and 3.84 km away from the active crater, respectively. We observed a relationship between the moment magnitude and the corner frequency of the explosion earthquake distribution. The result shows that the moment magnitude is inversely proportional to the corner frequency in a logarithmic scale using the full waveform of explosion earthquakes. The distribution equation of full waveform (0-20s) at KRA3 and KRA4 as follows; fc = −2.72145 log(Mw ) + 7.99523, and fc = −1.13971 log(Mw ) + 5.97855 respectively. The magnitude range is approximately 1.5–3 Mw. Meanwhile, the corner frequency range is about 4-8 Hz. Our result shows a similar distribution to those in the tectonic earthquake and volcano studies at different locations which is the magnitude is inversely proportional to the corner frequency. We also observed the relation between seismic moment and corner frequency which shows that the seismic moment is inversely proportional to the corner frequency with the range of seismic moment is about 1013-1015 N.m. Meanwhile, the stress drop is proportional to the corner frequency with the range of stress drop is about 100 and 103 bar. Our results are similar to those of other studies. These parameters show the basic statistical properties of volcanic eruptions. This study is important for understanding the dynamics of volcanic eruptions at the Anak Krakatau volcano.

“…The comparison of explosion earthquake of our study with another study on Sakurajima volcano, Japan is applied to understand the differences that indicate the mechanism of explosion earthquake. The characteristic of waveform of explosion earthquake at Sakurajima volcano, Japan occurs at about 30-50 s, then S/N ratio become smaller [15]. The waveform duration of explosion earthquakes in this study is longer than the general of observed explosion…”

“…The analysis of energy of explosion earthquake has been done investigated by hasib et al in [15] at different volcanoes, and shows the energy gradually decrease more than 50 s and continue stable for more than 50 s. In this study, the examining the waveform, spectra, and energy of explosion earthquakes during October to December 2014 at Sinabung volcano is investigated to characterize the explosion earthquake and to compare the result with another volcano to briefly understand its mechanism.…”

The characteristic of explosion earthquakes associated with lava avalanche at Sinabung volcano from October to December 2014 is investigated. The 1-component short-period seismometers which are Sukanalu (SKN), Laukawar (KWR), and Kebayaken (KBY) are used. All stations are located about 3-9 km away from the summit. The result shows the characteristics of these waveforms as follows; the amplitude increases rapidly to maximum for about 2-5 s, then the amplitude is almost constant for about 30-40 s followed by the gradual decrease of amplitude for about 40-50 s. Most of explosion earthquakes have a dominant frequency at about 1-4 Hz. The result also observed that the energy of explosion earthquake changes with lapse time and much stable for longer duration compared with explosion earthquake study at different volcano. Our result suggests that the explosion earthquake at Sinabung volcano may have a different waveform generation and/or mechanism to the general explosion earthquake at different volcano.

Sinabung volcano is one of the active volcanoes in Indonesia. the study used seismogram recording data from January - December 2015. from this period there were 163 volcanic earthquake events with 5 stations spread across the sinabung volcano area. this study is about the hypocenter distribution of the sinabung volcano earthquake. Hypocenter distribution is done using Geiger's method with Adaptive Damping (GAD). by analyzing the depth of the earthquake with a special technique (Geiger's method with Adaptive Damping), the hypocenter distribution is obtained at a depth of 1-5 kilometers.
