In this project, we came up a assumption that if 2012 were coming, where is the safest spots in Manhattan. We find some information about what will 2012 Bring if it were coming. The research shows that the most possible disasters including tsunami, hurricane, earthquake. Regarding these three different disasters, each disaster also has different affecting factors.
We gather some information in the GIS, and then did the research that how all these factors can affect people’s safety. Finally according to the diagram, we conclude where is the safest area and where is the most dangerous area.
THE ANALYSIS OF TSUNAMI
A tsunami is a series of water waves caused by the displacement of a large volume of a body of water, typically an ocean or a large lake. Earthquakes, volcanic eruptions and other underwater explosions, landslides, glacier calvings, meteorite impacts and other disturbances above or below water all have the potential to generate a tsunami.
According to our research, we find that several factors will affect the security coefficient when a tsunami comes, including BUILDING ALTITUDE, TSUNAMI CENTRE, BUILDING DENSITY, AND SO ON. After considering all the possible factors, we conclude where is the safest area when a tsunami comes as the figure shows.

THE ANALYSIS OF HURRICANE
A tropical cyclone is a storm system characterised by a low-pressure centre and numerous thunderstorms that produce strong winds and heavy rain.Tropical cyclones strengthen when water evaporated from the ocean is released as the saturated air rises, resulting in condensation of water vapour contained in the moist air. They are fuelled by a different heat mechanism than other cyclonic windstorms such as nor’easters, European windstorms, and polar lows. The characteristic that separates tropical cyclones from other cyclonic systems is that at any height in the atmosphere, the centre of a tropical cyclone will be warmer than its surrounding; a phenomenon called “warm core” storm systems.

ANALYSIS OF EARTHQUAKE
An earthquake is the result of a sudden release of energy in the Earth’s crust that creates seismic waves. The seismicity, seismism or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time. Earthquakes are measured using observations from seismometers. The moment magnitude is the most common scale on which earthquakes larger than approximately 5 are reported for the entire globe.
