A journey to earth science projects at Physics Department, Universitas Negeri Surabaya: Progress in recent years

Abstract

Earth Science Projects are research topics conducted by some people working on subjects related to hazard mitigation study on the basis of efforts in disaster risk reduction to maximize awareness of earth science and minimize possible risks of earth-related disasters. These people have joined Center for Earth Science Studies at Physics Department since 2011 and performed computational work, focusing on tsunamis, earthquakes, and volcano eruptions for reliable early warning system development. Other work has in part included applications of geophysical methods to localize hydrocarbon reservoirs using data analysis of broadband-noise spectral amplitude and low-frequency spectrogram, and distinguish underground nuclear tests from natural earthquakes of seismic origin. The Projects may also be relevant to science and/or physics education students as final projects with earth-related disasters as the main themes using laboratory approaches. Several publications made by the group members and students in recent years are therefore discussed, emphasizing on seismic hazard assessment and analysis. Future direction of possible research collaboration between research groups in the department will also be discussed in terms of challenges and technical difficulties.
