| description | Merapi volcano degassing event occurred in 15 July 2012 was recorded by
stations located in Pasar Bubar, Klatakan, Deles, Plawangan, and Pusung London.
Events marked with gusts of gas and fine material from the crater surface. During
the time, the characteristic of the degassing event have been unknown so a
comprehensive study of its seismicity is needed.
In this research, degassing event was analyzed using time frequency
analysis, crosscorrelation, and particle motion. The time frequency was analyzed
for stations in Pasar Bubar, Klatakan, Deles, Plawangan, and Pusung London.
Signal correlation had been calculated between station Pasar Bubar with station
Klatakan, Deles, Plawangan, and Pusung London. Particle motion analysis was
performed in three component seismic station, which are Klatakan and Pasar
Bubar to determine the back azimuth (α), incidence angle (i) and the dominant
direction of gusts event.
The results of the analysis showed that the range frequency of each
seismogram recorded at Pasar Bubar, Klatakan, Deles, Plawangan, and Pusung
london station is between 2-12 Hz. The correlation analysis result of degassing
events recorded by all stations shows that the small correlation (� = 0.32 to 0.55)
was associated with phase shift of wave propagation�s direction between stations.
Analysis of particle motion show that in Klatakan station, the value of back
azimuth (α) is 141 °and the incidence angle (i) is 227 °. Meanwhile, back azimuth
value (α) in the Pasar Bubar station is 154 °. The epicenter is located at 7 ° 32'54''
S and 110 ° 28'29'' E and the hypocenter is at a depth of 5982 m from the station
Klatakan. The dominant direction of degassing event when the cracks occured
was in the direction of the azimuth of horizontal plane |
