| Question | Answer |
| 1.The Earthquake - Magnitude of the quake: | 9.0
|
2.The Earthquake - Energy released by the quake: | 480 megatons (a magnitude 9.0 earthquake releases as much energy as 32,000 magnitude 6.0 earthquakes)
| 3.The Earthquake - Energy released by the quake compared to the nuclear attack on Hiroshima: | 600,000,000 times the energy of the Hiroshima bomb
| 4.The Earthquake - Size of the quake: | 5th biggest in World history
| 5.The Earthquake - Duration of strong shaking from the quake: | up to 5 minutes
| 6.The Earthquake - There were four warning earthquakes (foreshocks) in the days leading up the quake of magnitude: | 6.0, 6.1, 6.1 and 7.2
| 7.The Earthquake - Number of aftershocks: | more than 900 (aftershocks from a 9.0 magnitude quake can last for years)
| 8.The Earthquake - First aftershock: | There were 3 aftershocks of magnitude 7.0 or greater within 45 minutes of the quake
| 9.The Earthquake - The quake moved entire island of Japan (Honshu): | 2.4 meters (8 feet) closer to North America
| 10.The Earthquake - The quake shifted the Earth's axis: | 10 cm (4 in) at least
| 11.The Earthquake - The quake made earth days shorter by: | 1.8 microseconds
| 12.The Earthquake - Japan's earthquake warning system sent a warning to Tokyo residents: | 1 minute before the quake hit Tokyo
| 13.The Earthquake - The quake moved a 180 km wide stretch of seabed up: | 8 meters (26 feet)
| 14.The Tsunami - Peak tsunami height: | 40.5 meters (133 feet) at Miyako — that's equivalent to a 13 storey building. The Japanese tsunami scale considers a 3 meter tsunami to be a major tsunami.
| 15.The Tsunami - How far the tsunami made it inland: | up to 10 km (6 miles) at Sendai
| 16.The Tsunami - Total land area covered by the tsunami: | 561 kilometers sq. (217 sq. miles)

| 18.The Tsunami - Number of people who evacuated after the tsunami warning in the worst hit areas: | only 42%
| 19.The Tsunami - Designated tsunami evacuation sites that were hit by the wave: | at least 101
| 20.The Aftermath - Estimated cost of the disaster: | US$300 billion (biggest in World history)
| 21.The Aftermath - Number of buildings destroyed: | 45,700
| 22.The Aftermath - Number of automobiles and trucks destroyed: | 230,000
| 23.The Aftermath - Number of people killed and missing: | 15,828 deaths and 3,760 people missing
| 24.The Aftermath - Number of children killed: | 378 deaths and 158 children missing.
