“…According to the focal mechanism we obtained from Global Centroid Moment Tensor (GCMT) (Dziewonski et al 1981;Ekström et al 2012) (https://www.globalcmt.org/), it shows a normal faulting mechanism, while the surrounding events in the cluster are dominated by thrusting mechanism (Fig 12). Based on the location and depth, the seismicity in this cluster are intraslab events associated with intense deformation zone due to plates collision (Serhalawan et al 2017).…”

The Central and East Java region, which is part of Sunda Arc, has relatively high seismicity rates due to the convergence between two major tectonic plates in Indonesia region, the Indo-Australian plate that subducts under the Eurasian plate. Many devastating earthquakes in the study area occurred as results of these plates interaction, such as the 1994 Banyuwangi earthquake (Mw 7.6) and the 2006 Yogyakarta earthquake (Mw 6.3). This study aims to determine the precise earthquake This manuscript is a non-peer reviewed preprint submitted to EarthArXiv. It has been under reviewed for publication to Geoscience Letters on 13 Sept 2020 with submission ID GOSL-D-19-00015R2. Newer versions may be moderately different with slight variations in content. 2 location and analyze the pattern of seismicity distribution around Central and East Java, Indonesia. We manually re-picked P and S-wave arrival time recorded by Agency for Meteorology, Climatology and Geophysics (BMKG) of Indonesia network for the times period of January 2009-September 2017. We then determined the earthquake location by a non-linear method. To improve the accuracy of earthquakes location, we relocated 1,127 out of 1,529 events using a double-difference algorithm with waveform crosscorrelation data. Overall, the seismicity around Central and East Java regions are dominantly distributed in the south of the island, e.g. Kebumen, Yogyakarta, Pacitan, Malang, and Banyuwangi cluster. These clusters are probably related to the subduction activity. Meanwhile, the shallow depth earthquakes that are clustered in mainland indicate the activity of inland faults in the region, e.g. Opak Fault, Kendeng Thrust, and Rembang-Madura-Kangean-Sakala (RMKS) fault zone. Several other active inland faults have not shown significant seismicity over the times period, i.e.,

“…The other interesting question also comes from the far end of east Flores island, one village reported being lost due to being swept by the giant wave. This phenomenon was long discussed due to the anomalous 25 m run-up which struck the coastal zone of Riangkroko village [19,20].…”

In the 1990s there were 7 (seven) deadly tsunami events due to earthquakes in Indonesia. There is M 7.8 North-east of Flores island sea earthquake (1992), M 7.6 South of Java island sea earthquake (1994), M 6.8 South of Timor Island sea earthquake (1995), M 7.8 North-west of Sulawesi island sea earthquake (1996), M 7.9 East of Biak island sea earthquake (1996), M 7.7 Taliabu island sea earthquake (1998), and M 7.4 East of Banggai Island sea earthquake (2000). Those earthquake and tsunami disasters events affected the number of casualties and damaged houses in coastal areas. Surely those events present a few lessons learned for future disaster preparedness in Indonesia.
