Earthquake preparedness can significantly reduce damage and losses. Having early warning systems, constructing earthquake resistant buildings according to building codes, and educating the public on safety measures can help minimize harm. Japan's earthquake early warning system issues alerts through TV, phones, and internet, allowing people to take shelter quickly. A semiconductor manufacturer in Japan saw losses reduced from over $15 million to $200,000 after installing the early warning system and retrofitting buildings. Earthquake preparedness presents business opportunities in areas like early warning systems, retrofitting, and rising insurance demand.
