| Summary: | This study has the purpose to evaluate the earthquakes data that occurred
in the study area over a period of 14 years with a research focus on earthquake
studies, determination of the surface structure, and correlation between two of
them. The research area include the area of Yogyakarta region. Yogyakarta is an
aera which is frequently hit by the earthquakes, because of the location that fall
under the ring of fire. The earthquakes that are studied generally has shallow
depth, between 10km to 15 km, with a magnitude of 3-7 magnitude SR. by using
earthquake data downloaded from the USGS and obtained from BMKG
Yogyakarta, the epicenter of the earthquake can be projected into the map for the
research.
The study was conducted by projecting epicenter earthquake point on a
map, assisted by regional geological map, straight pattern from DEM. Then it will
conclude the connection between the point of the epicenter of the earthquake
occurred, and the location of the surface structure.
From the results of research studies Yogyakarta earthquake, found that
2006 is the year in which has the highest frequency of occurrence of earthquakes
with the largest magnitude up to 6, 4 magnitude ritcher scale. While on the surface
structure of the study, showed that the distance between the epicenter of the
earthquake to the structure of the surface has a little variation with a little bit
diversity. As the result of a standard deviation between 1-4 km, it can be
conclude that the epicenter of an earthquake in study area has close proximity to
the surface structure. |
