Man’s search for hospitable living space throughout our short history has placed us in the face of natural and man made hazards and the risks that they potentially present. Our history is beset by instances of natural hazards that have wrought destruction on those unfortunate enough to be within the vicinity of the event and those that felt the overall repercussions. The event on the island of Santorini in the Aegean comes to mind as a classical event of mass destruction in which a volcanic eruption destroyed all the settlements of the island and dissected the formerly single island, indirectly bringing the collapse of the Minoan civilization on nearby Crete. Theses events of mass destruction are infrequent in the context of overall time and history, but nevertheless should serve as examples of potential hazards and the aftermaths that follow, given the higher risks that exist in our modern, over-populated world. The collection of images displayed each presents a hazard that the modern world must face and adequately access to both mitigate and protect from potential risks and plan for new areas of development.
The top left image reveals the natural hazard of earthquakes that, depending on where you live in vicinity to a natural fault line, can have the potential for great death and destruction. The 1906 San Francisco earthquake is a prime example of an event in American history that influenced earthquake risk mitigation, which developed into a monitor and warn system of mitigating risk, but included safe zones, architecture evolution, infrastructure post-quake response, and urban planning. The image below that is a potential hazard as a result of an earthquake either on the surface or subsurface, a tsunami. Japan has historically experienced the destructive effects of tsunamis, with three major events striking the island since 1896, with the 2011 event being significant with the inclusion of a man made risk, radioactive contamination from a damaged nuclear power plant. The sheer destructive potential of a major tsunami can be seen in the 2004 Indian Ocean Tsunami, which led to the deaths of 230,000 people and the unsettling of 1.6 million. The greatest defense against the risk of a tsunami is education and warning systems to expedite evacuation of risk areas. The next image displays our historically old friend, the volcano. Given our intimate history with said friend, there are many examples of potential risks involved with living near a volcano and the risks of super volcanic eruptions such as Santorini and Krakatoa. The risks of volcanoes include the immediate heat, debris, and poisonous gases released by the volcano. In the case of the super volcanoes, the release of particulate matter into the atmosphere can adversely affect the climate, creating the potential risk of famine and other climate related devastation. The greatest defense against the risks of volcanoes is the monitoring of active sites and warning populated areas of the potential risk of an eruption. The top right image seems to display one of the man made hazards and potentials for risk, contamination due to a radioactive release from a nuclear power plant. Events such as Chernobyl, Three Mile Island, and Fukushima each present the potential for radioactive risk and highlight the need for proper management of plants and thorough analysis of plant locations and the possible hazards that are present at potential locations. Lastly, the final image displays a hazard that has been with us since we decided to settle down into clustered cities that were prime fire hazards. The best counter to potential fire destruction is the use of fire resistant building materials, adequate fire fighting resources and response time, and a well designed infrastructure. Ultimately, the presence of hazards have not prevented human beings from establishing roots in potentially dangerous areas, but these hazards have forced us to adapt to potential risks, because if anything humans are adaptive, perseverant animals.
The usual rules…don’t attempt to identify the particular disaster, just talk about hazard and risk in each of these instances…
