An earthquake struck Indonesia's Java Island on January 14, 2022, causing some minor damage.[1]
Tectonic setting[edit]
The earthquake's focus lies close to the major fault plane where the Indo-Australian Plate is being subducted beneath the Eurasian Plate. However, the focal mechanisms determined for this event shows reverse faulting at a high angle to the trend of the subduction zone and it has been suggested that the cause was deformation within the descending slab. Analysis of GPS data, tsunami run-ups and the effect of stress transfer compared to aftershock distribution supports a west-dipping reverse fault.[2]
Damage and casualties[edit]
Eleven homes were destroyed in the Sumur Regency and in Lebak Regency, 36 buildings sustained damage as well[3][4][5] An Islamic school had collapsed and cracks appeared at a mosque, a hospital and a wall in Jakarta.[6][7][8][9] A school in Lebak Regency was also sustained damage to the roof and toppled concrete walls of fence. One person was injured by falling concrete.[10]
