to choose the specific field of study. My decision to apply for master program in Seismology at University of Potsdam is driven by my strong desire to be able to explore earth structure and seismic condition of this earth‚ especially in Aceh. According to the geographical condition‚ Aceh‚ one of provinces in Indonesia‚ is located on the ‘Pacific Ring of Fire’ which causes many earthquakes every year. Seismology is crucially needed in Aceh to be explored for further study about earthquake. Lack

Earthquakes and Logarithms Earthquakes are responsible for a wast majority of natural hazards on our planet. This natural geological phenomena are almost impossible to predict‚ and they occur usually in zones of the planet that are prone to movement in the uppermost crust of the earth. Certain areas are more likely to experience earthquakes‚ and also the aftermath of the earthquakes can be just as destructive or sometimes even more. Different methods of measuring earthquakes have been implemented

Abby is a seismologist: she studies earthquakes and the way that the vibrations caused by earthquakes move through the planet. One of the goals of seismology is to predict earthquakes in order to warn people who live in the area where they will happen‚ but accurate prediction is
