Facts
11/3/11 2:46pm local time
8.9 magnitude earthquake triggered huge tsunami swept inland near city of Sendai in Miyagi prefecture.
The earthquake occurred as a result of thrust faulting on or near the subduction zone interface plate boundary between the Pacific and North America plates. (USGS, 11.03.11)
According to scientists Japan moved approximately 8 feet (2.4m) closer to North America and the force of the quake had caused the Earth to shift between 4 and 6.5 inches (10-16cm) on its axis.
General
quake and subsequent tsunami led to over 18,000 deaths.
2,184 people still missing 18 months on.
In places the tsunami waves reached as far as six miles (10k) inland and entire towns such as Minami Sanriku have virtually disappeared.
As a result of the tsunami, Japan also faced a nuclear disaster after reactors at Fukushima power plant were damaged in the floods.
Although relatively unaffected during the initial earthquake, Tokyo continues to experience strong aftershocks and scientists have warned that another powerful earthquake could hit the city very soon.
In a speech to the country, Japanese Prime Minister Naoto Kan called the disaster the 'worst crisis since World War II'.
Stringent seismic building codes and early warning system prevented many deaths from the earthquake.
Tourism
In April 2011, tourism numbers fell by over 60% compared to the year before. They are yet to recover to pre-tsunami levels, despite a new 12.1tn yen ($157bn; £100bn) budget for the reconstruction
The disaster even had a significant knock-on effect in other countries, with fewer Japanese tourists travelling abroad.
In the weeks after the tsunami, Kasikorn Research Centre predicted £650m of Thailand's tourism revenue would be lost because of the situation in Japan
The government did look at ways of including free flights to increase tourists to come back to japan.
Beach resort of Okumatsushima wiped from map.
Train station left a jumbled mess.
Train tracks torn and twisted.
Broken metal pieces from shipping container lies in beach.
Dramatic cliffs on the island of Miyatoshima cut off.
Nuclear emergency at Fukushima saw many foreign tourists to cancel trips.
Tanpo no Yado hotel chain said there was "no prospect" of resuming operations in Okumatsushima.
Indonesia sits above the "Ring of Fire:
series of fault lines
make archipelago nation of approx. 18,000 islands prone to volcanic and seismic activity.

Roger Musson, a seismologist from the British Geological Survey, said:
where ground had been pushed under the continental plate, "flipping up" the seabed.
"It seems to be a large earthquake within the Indian Plate and the plate has broken in a sort of lateral way,"
"It's a sort of tearing earthquake, and this is much less likely to cause a tsunami because it's not displacing large volumes of water.”

US Geological Survey (USGS) measured the center of the earthquake at a depth of 33km (20 miles), about 495km from Banda Aceh.

Sutopo, a spokesman for Indonesia's disaster mitigation agency, said electricity had been cut off. Traffic jams were reported in Aceh, where people scrambled for higher ground as sirens mingled with sounds from the mosques.
Ten meter tall waves passed northern tip of island to race south down the straits of Malacca and strike along the northeast coast as far as as east of Lhokseumawe.
residents forced to evacuate the place.
What physically happened
The UN estimates: 655,000 people homeless and sheltering in scattered refugee camps across the province.

Destroyed coastline, concrete pads, several numbers of bridges collapsed, and lack access of roads.

As of January 23, 2005 the Health Ministry reported 173,981 dead. On 25 January Health Minister Fadilah Supari updated the estimated death total to 250,000.
General Physical Impact
“I think this is awesome!” Ponny said. “The people in this ship, nobody die, so this is a miracle.”Ponny is among the growing numbers of tourists who have come to Aceh some seven years after the tsunami to see the relics of destruction. Around the wreckage, facilities have sprung up, with viewing platforms, drink vendors, and snack shops.
Petriani and her sister have opened a popular noodle shop under the beached boat. Petriani said after the tsunami this place became very well-known.“That’s why my sister and I took the place. And word of mouth spread quickly, so people know the place and it’s easy to find us here,” Petriani said.
“I didn’t expect it, actually, how it looked like,” said Erlbrich Elsenga, who’s here from the Netherlands, looking up at the fishing boat on the house. “It’s different from what I expected, it is a big boat. I thought it was maybe a small boat on top of a small house, but really big.”
Officials say more tourists come to see the aftermath of the tsunami than come for the area’s wide, sandy beaches.
Creation of spiritual tourism. Yusny Saby, a professor at the State Institute of Islamic Studies in Aceh, said it may sound morbid, but it’s actually very healing. Saby said. “If it were not for the tsunami, we would have still been in war. So the tsunami is a sort of blessing in disguise. We lost a lot, but it speeded up the process of bringing peace.”The peace came after a nearly 30-year civil war between Acehnese rebels and the government of Indonesia. And that’s become another draw for tourists.

Duration 40-300 seconds

Magnitude of 7.4

Situated atop three of the large tectonic plates that constitute the earth's surface, Mexico is one of the most seismologically active regions on earth. The motion of these plates causes earthquakes and volcanic activity.

Some rural areas affected by over 30,000 houses damaged or destroyed.
At least 800 houses were damaged in Guerrero state.

Casualties: 48 deaths 11 people injured.

125,000 people without power.

About 40 passengers stranded for a short time on the Mexico City airport. The airport was closed for a while.

Mobile phone networks affected, people had trouble contacting loved ones.
Tourism impact



The 7.4-magnitude earthquake that struck the northern Pacific coast of Costa Rica did not significantly disrupt tourism operations in the country, the Costa Rican Association of Tour Operators and the Costa Rican Chamber of Hotels, reports that “tourism is operating normally throughout the country.”

As the most active volcano in indonesia
10,000 people evacuated 2.5 km away from the crater.
