| Summary: | A preliminary study have been carried out to observe the influence of the tidal
force as a trigger for earthquakes with magnitude M � 6.4 in Indonesia from 2001
to 2011. Tidal force was calculated by using Gotic2 program developed by the
National Astronomical Observatory of Japan. The GOTIC2 program was tested
by comparing it�s result with the observed gravity data for 10 days at Jalan Kenari
Yogyakarta (7° 47 '55.14'' S and 110° 23' 16:41'' E, with elevation 109.12 m
above sea level).
53 earthquakes events were studied to correlate with tidal force by calculating the
tidal phase angle at the time of the earthquake happen. From this study it is found
that 87% of earthquakes at the time of maximum tidal force. This support the
indicated that tidal force can trigger earthquakes. For the analysis shows that M =
6.4 Yogyakarta at 26 Mei 2006 was triggered by tidal effect. |
