| Summary: | Micro-seismic monitoring at Bledug Kuwu area using three components
seismometer has been measured. The aim of this monitoring is to analyze the
internal dynamics of mud eruption in Bledug Kuwu from a certain depth to the
surface.
Data were collected from the record of three seismometers which were
installed simultaneously forming a triangle with the eruption source in the center.
The internal dynamics of the mud eruption in Bledug Kuwu was obtained by
analyzing the pattern of source motion which is showed by the change of
Azimuth, Back-Azimuth, Incidence angle and depth of the source as a function of
time.
According to the analysis results, the internal dynamics of fluid bubble
eruption of Bledug Kuwu can be detected. The internal dynamics eruption of
Bledug Kuwu is vertically distributed. It can be identified by the azimuth direction
from station to source which is relatively constant and the indication of incident
angle shifted as a function of time. The epicenter position is shifted about (20-25)o
from the estimated center eruption. The average depth of the hypocenter is about
200 meters from the earth�s surface. |
