Remote Sensing - Design of a Spaceborne Sensor Essay

Remote Sensing - Design of a Spaceborne Sensor - Essay Example For these earthquakes prediction and monitoring, lots of works are being done and lots more are in progress. These include a wide range of technologies such as seismographs, accelerometers and satellite imagery. All provides information having vital importance depending on area and costs. The upcoming technologies are thought to have more significant features that hopefully are able to predict the earthquakes with more accuracy and vivid predictions that will help to mitigate the population even before the earthquake would have occurred. Earthquakes are occurred by the movement of ground due to insufficient stress and strain in the earth’s tectonic plates. It could cause devastating effect when it magnitudes are high and the duration of the earthquake is also high. The death toll could increase to thousands within seconds after the earthquake of high intensity has occurred. The devastating effect also depends on the quality of the infrastructure and more importantly the prepar edness for the disaster. In most cases, because of the rapid ground shaking without any warnings and early signs usually there is a lot of destruction because it is not easy to predict when the earthquake will occur. According to the EAS, The effect of earthquake includes landslides, shaking, tsunamis and liquefaction (EAS, 2011). Most of the death toll is due to the collapse of the infrastructure whereas other reasons also exist. The post traumatic stress disorder is also a reason for the death toll to rise even after the earthquake. Here are some pictures of earthquake destruction as follows There are different methods by which the earthquakes are determined. These methods includes the use of different wavelengths for predicting the change in the structures of the rock, the light that is reflected from the minerals present in the rocks and also the use of graphs that monitors different waves that are caused because of the movement of the tectonic plates. The different methods that are used are stated below that either monitor is used to predict the future earthquakes that are likely to happen. Space borne sensors:- The space borne sensors are used in many different fields and the one important filed is used to predict the earthquakes and study the behavior of rocks that are altered after the earthquakes. The land Sat satellite is used in different field that includes the field of the geologist. It travels in different directions and with the help of the earth’s revolving around the axis, with the help of electromagnetic waves it takes the snaps and are compared with previous data and experts by making calculations can predict where might the next earthquake could occur. The diagram below shows its behavior of working. With the help of geologic maps that are taken from the satellites, the seismologists evaluate the seismic activity and it helps them to predict the earthquake, though not utmost success but still helps to widen the knowledge. According t o NASA the magnitude 9.0 earthquake struck and these images were found very helpful in determining the earthquake destruction (NASA, 2007). Boeing Constant WC-135 Phoenix: - It is a military aircraft that is used by The United stated for determining the nuclear and seismic activity on the ground and it is found to be very helpful in determining the situations. In certain cases because of the nuclear activity is altered due to earthquakes because of
