Shaking was intense with an assigned Rossi–Forel intensity of VII (Very strong tremor) and intensity of VI (Strong) on the Modified Mercalli intensity scale. This oblique-slip event generated a destructive tsunami of up to 1.5 metres in the Banda Sea region, but there were no deaths. Tectonic setting The Banda Sea is located within a very complex tectonic regime that accommodates the convergence between the Australian plate and the Sunda plate. The Molucca Sea plate, Bird's Head plate, Timor plate, and Banda Sea plate all help accommodate the elaborate plate boundary system in the region.Kaymakci Decker Orange Teas 2015Bird 2003 This collection of microplates leads to large amounts of seismicity in the area, including the 1852 Banda Sea earthquake which was potentially a w8.8 event, as well as the 1629 Banda Sea earthquake which was also estimated at up to w8.8.Fisher Harris 2016Ringer Whitehead Krometis Harris 2021Major Liu Harris Fisher 2011 Earthquake At around 04:00 local time, a large earthquake started to shake the Banda islands. The earthquake was assigned a moment magnitude (w) of 8.5–8.6 and caused a destructive tsunami of 1.5 m on at the Kai islands.Cummins Meilano 2017Okal Reymond 2003 The tsunami expected for an earthquake of this size is much greater, such as of those in 1629 and 1852, however this earthquake occurred at a depth of 60 km which impeded much of the ocean floor displacement which leads to a tsunami.Okal Reymond 2003 Due to its depth, the earthquake was felt strongly in far away Darwin and as far as Merauke and Daly Waters.Okal Reymond 2003McCue 2013 In Darwin, concrete floors cracked and windows were damaged.McCue 2013 This earthquake is of significant scientific interest as it remains a mystery as to precisely which fault produced this earthquake. Some studies consider this earthquake the largest intraslab earthquake on record.Cummins Pranantyo Pownall Griffin 2020 Tsunami Despite being a large thrust faulting event, the tsunami was rather small. This is assumed to be caused by the 60 kilometer depth. At the Kai islands, runups of 1.5 m on were recorded.Cummins Meilano 2017 Beachfront damage was reported across the Tayandu Islands and the entire Banda region.Okal Reymond 2003 See also List of earthquakes in 1938 List of earthquakes in Indonesia 1852 Banda Sea earthquake Weber Deep References ISC-GEM Global Instrumental Earthquake Catalogue (1900–2009) http://www.isc.ac.uk/iscgem/index.php ISC 27 June 2022 International Seismological Centre Version 9.1 Significant Earthquake Database https://www.ngdc.noaa.gov/hazel/view/hazards/earthquake/event-more-info/3609 National Geophysical Data Center / World Data Service (NGDC/WDS) National Geophysical Data Center, NOAA 10.7289/V5TD9V7K 1972 Data Set Sources Bird P.
