were rapidly mobilized to deal with the crisis.
What did Japan do to prevent the tsunami?
As with most tsunami-prone areas, Japan has developed a mixed strategy that primarily relies on
evacuation
rather than defense. As seismic detection and preemptive warnings improve, death tolls can, and likely will be, reduced over time.
What did Japan do to prepare for the 2011 earthquake?
- Earthquake-resistant buildings.
- Phone updates.
- Earthquake-ready bullet trains.
- Immediate TV coverage.
- Awareness and education on disaster prevention.
- Earthquake Memorial Museum.
- Earthquake survival kits.
- Water Discharge Tunnel.
Does Japan have a tsunami warning system?

Japan has one of the most advanced earthquake early-warning systems in the world
. It detects tremors, calculates the epicenter, and sends out warnings from over a thousand seismographs scattered throughout the country.

How can you predict a tsunami is coming?
To help identify and predict the size of a tsunami,
scientists look at the size and type of the underwater earthquake that precedes it
. This is often the first information they receive, because seismic waves travel faster than tsunamis.
