The 1982 Flores earthquake struck the island of Flores in Indonesia on December 25. Registering a moment magnitude of 5.9, according to the International Seismological Centre, it created landslides and was reportedly accompanied by a tsunami. The earthquake killed thirteen people and left 390 injured, also destroying 1,875 houses [4] and 121 other buildings. [5] The villages of Layahong and Oyong Barang were damaged by seven seconds of shaking. [6]

Tectonic setting

The Lesser Sunda Islands lie in a region with frequent seismicity, and there is a history of tsunamis in the area. Both the subduction of the Australian Plate and the crust in the Flores Sea could be responsible for this activity. [7]

Impact

The five most affected districts were evacuated of 6,000 people. The local and regional governments were petitioned for supplies like tents, medicine, and food. The earthquake was followed by several aftershocks. [5]

The 2005 Nias–Simeulue earthquake occurred on 28 March off the west coast of northern Sumatra, Indonesia. At least 915 people were killed, mostly on the island of Nias. The event caused panic in the region, which had already been devastated by the massive tsunami triggered by the 2004 Indian Ocean earthquake, but this earthquake generated a relatively small tsunami that caused limited damage. It was the third most powerful earthquake since 1965 in Indonesia.

The September 2007 Sumatra earthquakes were a series of megathrust earthquakes that struck the Sunda Trench off the coast of Sumatra, Indonesia, with three of magnitude 7 or greater. A series of tsunami bulletins was issued for the area. The most powerful of the series had a magnitude of 8.5, which makes it in the top 20 of the largest earthquakes ever recorded on a seismograph.

The 1992 Flores earthquake and tsunami occurred on December 12 on the island of Flores in Indonesia. With a magnitude of 7.8 and a maximum Mercalli intensity of VIII (Severe), it was the largest and also the deadliest earthquake in 1992 and in the Lesser Sunda Islands region. The earthquake was caused by slip on the Flores Thrust fault. This fault dips to the south underneath Flores Island. The epicenters of most earthquakes on the Flores Thrust are on Flores island.

The April 2010 Sumatra earthquake occurred on April 7 at 5:15 AM local time with a moment magnitude of 7.8 and a maximum Mercalli intensity of V (Moderate). The shock occurred near the Banyak Islands, off the island of Sumatra in Indonesia. A tsunami watch was issued according to the Pacific Tsunami Warning Center in Honolulu which was later canceled. A 40 cm surge was reported in the Banyak Islands an hour after the quake, along with 62 injuries. Power outages were reported throughout the province of North Sumatra as well as in Aceh. This quake is one in a sequence of large earthquakes along the Sunda megathrust in the 2000s.

The 2010 Papua earthquake occurred on June 16 at 12:16 local time in Papua province of Indonesia. The magnitude 7.0 mainshock was preceded by an Mw 6.2 foreshock 10 minutes earlier, and was followed 42 minutes later by an Mw  6.6 aftershock.
