What areas were affected by the Indian Ocean earthquake?
Measured in lives lost, this makes it one of the 10 worst earthquakes in recorded history, as well as the single worst tsunami in history. The worst affected countries were India, Indonesia, Malaysia, Maldives, Myanmar, Sri Lanka, Seychelles, Thailand and Somalia.
What type of plate boundary was the Indian Ocean earthquake?
The December 26, 2004 magnitude (M) 9.1 Sumatra-Andaman earthquake occurred along a tectonic subduction zone in which the India Plate, an oceanic plate, is being subducted beneath the Burma micro-plate, part of the larger Sunda plate.
Is the Indian Ocean prone to earthquakes?
Because of its relatively low seismicity and limited recorded historic earthquakes it has often been considered incapable of generating major earthquakes. Plate boundary faults at subduction zones are expected to be prone to rupture generating earthquakes at temperatures of between 150 and 450 °C.
Where did the Indian Ocean tsunami hit?
The Indian Ocean tsunami of 2004 lasted for seven hours and reached out across the Indian Ocean, devastating coastal areas of Indonesia, Sri Lanka, India, Maldives, and Thailand, and as far away as East Africa.
Which country was hit hardest by the 2004 tsunami?
Sweden was likely the most seriously affected country outside of the disaster area. According to Swedish authorities, some 20,000–30,000 citizens were in the tsunami-affected areas at the time, mainly in Thai resorts.
Why are there earthquakes in the Indian Ocean?
The Indian plate is a heavy ocean plate, and it slipped under the lighter coastal plate, rupturing a 900-mile length of the fault. Indonesia lies between the Pacific Ring of Fire, where 90% of earthquakes occur, and the second-most active seismic zone, the Alpide belt.
How often do earthquakes occur in the Indian Ocean?
about once every 230 years
Sieh says that earthquakes in the region happen about once every 230 years.
Where are the earthquake zones in India located?
Regions that fall under the Earthquake (seismic) Zones in India Zone-V covers entire northeastern India, some parts of Jammu and Kashmir, some parts of Ladakh, Himachal Pradesh, Uttarakhand, Rann of Kutch in Gujarat, some parts of North Bihar and Andaman & Nicobar Islands.
What was the size of the 2004 Indian Ocean earthquake?
The 2004 Indian Ocean earthquake came just three days after a magnitude 8.1 earthquake in the sub-antarctic Auckland Islands, an uninhabited region west of New Zealand, and Macquarie Island to Australia’s north. This is unusual since earthquakes of magnitude eight or more occur only about once per year on average.
Why are there so many earthquakes in the Indian subcontinent?
The Indian subcontinent has a history of devastating earthquakes. The major reason for the high frequency and intensity of the earthquakes is that the Indian plate is driving into Asia at a rate of approximately 47 mm/year.
Which is the most seismic active region in India?
Of all these four zones, Zone-V is the most seismic active region whereas Zone-II is the least. Zone-V covers entire northeastern India, some parts of Jammu and Kashmir, some parts of Ladakh, Himachal Pradesh, Uttarakhand, Rann of Kutch in Gujarat, some parts of North Bihar and Andaman & Nicobar Islands.
