Tsunami proof technology

Natural disasters are an inevitable and unpredictable fact of life in many regions of the world, with technology offering one of the only realistic lifelines in boosting preparedness. Following the 2004 Indonesian Tsunami that killed around 225,000 people, US Aeronautical Engineer Julian Sharpe came up with a design for a tsunami-proof “Survival Capsule”. The idea was to provide a container that can house 2-10 people and withstand the destructive force of a natural disaster such as a tsunami, tornado, hurricane, earthquake or major flood, offering those with limited mobility a realistic option of escape. His prototype received positive feedback at the Yokohama disaster Preparedness Exposition of 2013 and the Survival Capsule has since gone into production. youtube.com/watch?v=5rBkOXdm45k

Clear evacuation routes

In countries or areas that have been struck by Tsunami it is common to see danger zones and evacuation routes clearly sign posted as the tsunami risk is considered higher in these areas. Likewise in countries such as Japan, where Tsunami’s a relatively frequent, clear marking of how high previous tsunamis went, the inundation height, is common, and helps to demonstrate how far you are likely to have to go before reaching safety. Routes to near by tsunami-proof buildings could also prove useful if there is a structure such as this in the vicinity.

Escape is the most realistic option to minimise the loss of life

Tsunami’s are unfortunately an incredible destructive forces, and it is hard to even predict the wave height from the measurements we can make with modern seismograph technology. The difficulty in predicting the occurrence, the scale and the level of destruction of a tsunami leaves escape as the only real credible option when mitigating the damages to human lives in the case of such disasters. There are technologies however such as the Deep-ocean Assessment and Reporting of Tsunamis (or DART II) system, that detect pressure changes on the seafloor in order to help predict and warn people of an impending tsunami.
