Current ‘significant’ earthquake in Indonesia:

– Seismicity in West Java 1 January 2019 to 16 February 2020 (Click here).


– The 25 September 2019 Mw 6.5 Ambon earthquake: (Click here to download our article about this earthquake in the Indonesian language)



– The 2 August 2019 Mw 6.9 earthquake located near Sunda Strait, Southwestern Java. Here I compute the finite fault model by using teleseismic waveform. The earthquake produced anomalous large ground motion and had a deficiency of aftershocks’ productivity.2019sunda_position
