How can technology improve earthquake safety in a place like Tokyo?

When it comes to technology in Japan, Is Japan Safe (2013) found:

"Research highlights that Japan is subject to regular seismic activity and has minor earthquakes and these will occur on a regular basis. Experts estimate Japan has a 70% chance of experiencing a 7.0+ magnitude earthquake over the next four years. However, the percentage of all of their earthquakes that can be felt is quite low, let alone the figure that actually cause fatalities.

Due to their challenging circumstances, Japanese society has used technology to adapt to these severe events. Examples include:

- Ability to predict earthquakes and monitor trends in seismic activity.

- Improved communication systems to alert people to dangers of earthquakes and resulting tsunamis and to be able to respond should a disaster occur.

- Most modern Japanese buildings are built to withstand earthquakes and can absorb the shock without collapsing.

- People in Tokyo are trained how to respond should an earthquake occur.

- Counter measures against tsunamis, such as physical walls built on the Japanese coast and evacuation facilities built on high ground."
