| Тойм: | Earthquakes pose a significant risk to the safety of our society and communities. With
improved technology and measuring tools, earthquake data have become more accessible
and grown in size. However, it is challenging to conduct an efficient earthquake analysis on
those large amounts of data. To address this problem, this project proposes a web-based real time earthquake visualization tool, QuakeVisual, that offers users a more interactive way to
analyse earthquakes. The QuakeVisual allows queries on earthquake timing, location, and
magnitude and can visually display the results in a 2D map view with regular circle nodes
and cluster form nodes. On top of that, it also provides an accelerated playback of the
earthquake events feature which animates the earthquake points in time sequence. To
evaluate the effectiveness of the various features provided by QuakeVisual, a user study was
conducted. Results from the user study showed that features provided in QuakeVisual have
increased the users’ querying speed for the earthquakes, and the playback of earthquake
events has allowed users to gain more insights about the temporal patterns of earthquakes.
