Technology can be used in a variety of ways. It can be used to manage the hazard as well as the vulnerability and loss. Despite the fact that unlike volcanoes, there is no definite or set method on predicting earthquakes, technology in terms of seismographs and tilt meters are used to give a slight clue.
One method of reducing the impact is by managing the vulnerability. One of the main uses of technology is the prediction of when and where an earthquake will occur. In terms of earthquakes it is very hard to predict when an earthquake will occur. However, there are tell-tale signs that give a nonetheless small idea. Technology here plays an important part; seismographs probably being the more common use. Little movements/ tremors under crusts are measured by seismographs and tilt metre; this information is looked at and then used to predict when. Radon gas is released which is measured by spectrometers. Water levels are also tend to rise before an earthquake giving a big hint. In addition to this land use planning uses GIS. This way the government can build important buildings such as official governmental offices in areas that are not risk prone. Earthquakes often require data to be collected from a variety of locations very quickly under adverse conditions. GIS is used to assess the risk and hazard prone areas in terms of population, property and natural resources. It can also be used to determine how and where aid should be assigned. It can also be used to assess short term and long term recovery operations. In Japan, the 6.8 magnitude Niigata Chuetsu earthquake in 2004 used GIS to develop three applications of GIS that were important to the response.
Another technique of managing vulnerability is community planning. Education and preparation are cost effective. The government can plan evacuation routes, and educate people. Even though education is
