What were the effects of the Sumatra earthquake?

Ten people were reported killed, and flooding destroyed a major bridge between the capital Port Victoria and main airport. Also, the island reported devastating economic loss in millions of dollars due to hotels, housing, public utilities, and fishing damages. More than 300 deaths were reported and 5,000 displaced.

What were the effects of the Boxing Day tsunami?

Through this source I learned that the direct impacts of the tsunami were damage to infrastructure such as utility lines, communication networks and transportation systems. While the indirect impacts were things such as the loss of tourism to Thailand and therefore a loss of income for many people who lived there.

Who was affected by the 2004 Sumatra earthquake?

The tsunami killed at least 225,000 people across a dozen countries, with Indonesia, Sri Lanka, India, Maldives, and Thailand sustaining massive damage. Indonesian officials estimated that the death toll there alone ultimately exceeded 200,000, particularly in northern Sumatra’s Aceh province.

How did the 2004 tsunami affect Sumatra?

The tsunami waves ranged from 4 to 39 meters high and destroyed more than 250 coastal communities. In the low-lying areas of western coastal Sumatra, including the city of Banda Aceh, the tsunami waves extended inland as far as 5 kilometers, affecting a large portion of the population of 300,000.

What damage did the 2004 earthquake cause?

The quake caused the ocean floor to suddenly rise by as much as 40 meters, triggering a massive tsunami. Within 20 minutes of the earthquake, the first of several 100-foot waves hit the shoreline of Banda Aceh, killing more than 100,000 people and pounding the city into rubble.

What caused the Sumatra earthquake 2004?

The tsunami from the 2004 M=9.1 Sumatra-Andaman earthquake was primarily caused by vertical displacement of the seafloor, in response to slip on the inter-plate thrust fault (see Tectonics section above). The other, the local tsunami, travelled towards Indonesia, Thailand, and nearby islands in less than an hour.

What environmental effects did the tsunami have on Indonesia?

Environmental Impact In the affected region, crops were destroyed and farm land was ruined by the salt water. Many forest and trees such as mangrove forests along the coast were also destroyed. Coral reefs and coastal wetlands were damaged.

What are the effects of tsunami in points?

The majority of deaths associated with tsunamis are related to drownings, but traumatic injuries are also a primary concern. Injuries such as broken limbs and head injuries are caused by the physical impact of people being washed into debris such as houses, trees, and other stationary items.

What caused the earthquake in Indonesia 2004?

The earthquake was caused by a rupture along the fault between the Burma Plate and the Indian Plate. A series of massive tsunami waves grew up to 30 m (100 ft) high once heading inland, after being created by the underwater seismic activity offshore.

How long did the Sumatra earthquake last?

Rather than tearing the land apart all at once, the rupture started beneath the epicenter marked in the figure below and progressed northward along the fault at about 2 km/sec (1.2 miles/second). The whole rupture lasted about 10 minutes.

How big was the earthquake in Sumatra in 2004?

This eyewitness assessment of damage from the earthquake and tsunami yields lessons for engineers. On December 26, 2004, at 07:58:50 local time, a powerful earthquake, moment magnitude (MW) 9.2, occurred in the Indian Ocean. The Sumatra-Andaman earthquake was one of the three largest earthquakes ever recorded.

Where was the tsunami in Indonesia in 2004?

On 26 December 2004, a magnitude 9.1 earthquake (3.316 N, 95.854 E, depth 30 km) occurred off the coast of northern Sumatra, Indonesia.

How is the hingeline related to the Sumatra earthquake?

During the 2004 Sumatra-Andaman earthquake, the seafloor on the overriding Burma plate deformed vertically, uplifting seaward toward the trench and downdropping (subsiding) landward toward the coastline. The line in map view where offshore uplift gives way to subsidence near the coast is termed the hingeline.

Where was the epicenter of the Sumatra Andaman earthquake?

The Sumatra-Andaman earthquake was one of the three largest earthquakes ever recorded. The fault rupture propagated 1,300 to 1,600 kilometers northwest for about 10 minutes along the boundary between the Indo-Australian plate and the Eurasian plate, from northwestern Sumatra to the Nicobar Islands and to the Andaman Islands.
