Development of near real-time and archival Tsunami data visualization dashboard for Indonesia

Abstract

Tsunami is a prevalent issue in Indonesia ever since the 2004 Andaman Sea Tsunami. Various measurement systems are installed, such as broadband seismometers, tide gauges, and buoys are used to enhance the Indonesian Tsunami Early Warning System (InaTEWS). These data are held by their authorized organizations, to provide a quick overview of all Tsunami related data, a visualization platform is proposed showing earthquake and tidal height observed by tide gauge stations and tsunami buoys. This paper shows the development of such a platform and discusses the architecture and data flow from each data provider. The prototyped dashboard can successfully visualize the spatiotemporal data for near real-time Tsunami observation data and historical archived data to view past Tsunami events of the 2018 Tsunami in Palu.
