This document discusses various preparedness measures that can be taken to reduce the impact of earthquakes and tsunamis, including land use regulations, infrastructure development, emergency drills, and earthquake monitoring systems. Land use regulations involve stipulating which areas are suitable for residential or industrial development to avoid high risk zones. Infrastructure aims to build earthquake-resistant structures using both high-tech and low-tech methods. Emergency drills educate the public on evacuation procedures. Earthquake monitoring systems can provide early warnings by detecting seismic activity.
