Editing Flores (section)

== Seismology ==
Flores Island is bounded by active tectonic regions, with the [[Sunda Trench]] to the south and the [[Flores back-arc thrust fault]] to the north. As a result, the island experiences many earthquakes each year and on occasion, tsunamis. The largest recorded earthquake in the region was the [[1992 Flores earthquake and tsunami]], a magnitude 7.8 event that caused Severe shaking on the [[Modified Mercalli intensity scale|Mercalli intensity]] scale. The Flores back-arc thrust is of particular interest to researchers as it is believed to accommodate the transition between the Sunda Trench in the west and the subduction of the [[Australian plate]] in the east. The Flores [[Thrust fault|Thrust]] is approximately 450&nbsp;km long and consists of a deep rooted basal fault and many overlying imbricate thrust faults. The system is highly active, with more than 25 earthquakes of a magnitude 6 or above since 1960. In 2018, a large sequence of earthquakes (such as on the [[5 August 2018 Lombok earthquake|5th of August]] and in [[July 2018 Lombok earthquake|July]]) in [[Lombok]] ruptured sections of the Flores Thrust. The dip of the main thrust fault of approximately 2–3° compared to the 3–4° dip of the subducting plate on the Sunda Trench leads some to believe that the fault could someday be the site of a [[subduction polarity reversal]] and begin subducting.<ref>{{Cite journal|url=https://academic.oup.com/gji/article/221/2/758/5757908|title=Did the Flores backarc thrust rupture offshore during the 2018 Lombok earthquake sequence in Indonesia?|author1=Xiaodong Yang|author2=Satish C Singh|author3=Anand Tripathi|date=25 February 2020|access-date=2024-02-12|journal=[[Geophysical Journal International]]|volume=221 |issue=2 |pages=758–768 |doi=10.1093/gji/ggaa018 |doi-access=free }}</ref>

A volcanic eruption in southeast Flores triggered earthquakes that killed at least 10 people as of 4 November 2024. Authorities warned of the possibility of more earthquakes in coming days.<ref>[https://www.nytimes.com/2024/11/04/world/asia/indonesia-volcano-eruption.html "At Least 10 Killed in Indonesia After Volcano Erupts"], ''[[The New York Times]]'', Nov. 4, 2024</ref>
