How big was the Indonesian tsunami 2018?
Indonesia was hit with several major earthquakes and tsunamis in 2018 with the first major ones striking off Lombok on 29 July 2018 with the magnitude of 6.4 and followed by a 7.4 magnitude earthquakes, tsunami and liquefaction in Central Sulawesi on 28 September 2018, damaging hundreds of thousands of houses in both …
What happened in Sulawesi Indonesia?
A 7.4 magnitude earthquake struck off the coast of Indonesia’s South Sulawesi province, prompting people to evacuate homes and buildings. The earthquake happened around 10.30 local time (03:30 GMT) on Tuesday in the Flores Sea.
What happened in Palu Indonesia?
On 28 September 2018, a magnitude 7.5 earthquake shook Sulawesi Island in Indonesia and triggered a tsunami that pummeled Palu, the provincial capital. The quake and the resulting tsunami, with waves that topped 5 meters in Palu Bay, wreaked extensive damage on one of Indonesia’s largest and most populous islands.
What caused the Palu earthquake?
The earthquake was caused by movement on the Palu-Koro fault. Geodetic evidence suggests that about 150 km of the fault ruptured. During the mainshock, the rupture propagated at speeds in excess of the S-wave velocity as determined by back-projection of teleseismic data, and supported by satellite geodesy.
How far did Indonesia tsunami travel inland?
In many places, the waves reached as far as 2 km (1.2 mi) inland. Because the 1,600 km (1,000 mi) fault affected by the earthquake was in a nearly north–south orientation, the greatest strength of the tsunami waves was in an east–west direction.
How tall was the Sulawesi tsunami?
Background. On 28 September 2018, a 7.5 magnitude earthquake struck Central Sulawesi, Indonesia, resulting in 1.5 metre tsunami waves that caused widespread damage and destruction to the areas of Palu and Donggala.
How high were the waves in the Indonesia tsunami?
This quake caused the Indian Ocean tsunami of 2004, which reached out across the Indian Ocean, devastating coastal areas with waves that in some places reached a height of 30 feet (9 metres) or more when they hit the shoreline.
When was the Palu tsunami?
September 28, 2018 at 3:02 AM PDT2018 Sulawesi earthquake and tsunami / Start date
Why does Indonesia have so many earthquakes?
The Indonesian archipelago is located on the tectonic zone where the Pacific, Eurasian, and Indo-Australian plates collide. Because Indonesia is at the center of a complex tectonic zone, earthquakes occur almost every day more than three times.
What plates caused the Sulawesi earthquake 2018?
The January 15 event was a shallow crustal earthquake at the boundary between the Sunda plate and the Banda Sea microplate at a focal depth of 18 km. The earthquake occurred along the Mamuju–Majene thrust fault, which is known to be an active seismic source that has caused several deadly earthquakes in the recent past.
How much did the Sulawesi tsunami cost?
The magnitude 7.5 earthquake and tsunami that struck Central Sulawesi in September of 2018 was particularly tragic, resulting in 4,402 deaths, approximately 170,000 displaced people, and USD1. 3 billion in economic losses.
What was the worst earthquake in Indonesia?
The strongest earthquake in Indonesia happened on 12/26/2004 in the region Sumatra (Aceh: Off West Coast) with a magnitude of 9.1 on the Richter scale. The shifting of tectonic plates in a depth of 53 km resulted in 1001 deaths. The earthquake also triggered a tsunami with further victims and destructions.
What was the deadliest tsunami ever recorded?
What is the deadliest tsunami in history? The deadliest tsunami in history occurred in the Indian Ocean in 2004. It was the result of an earthquake off the coast of Sumatra that took around 230,000 lives across fourteen countries.
