In seismic research, a working hypothesis is that ionospheric disturbances is related to lithosphere activities such as earthquakes. Domain scientists are working to find patterns from certain ionospheric attributes related to seismic activities. However, to find patterns from large amount of data is challenging, since it is hard to extract, formulate and search patterns. To address on these challenges,we developed an interactive system which supports the workflow of seismic research on ionospheric data. Our system can assist domain scientists to propose and examine hypotheses on relationships between ionospheric disturbance and seismic activities.
