Abstract
This paper presents a mobile application and a web-based geographic information system for an efficient and cost-effective sharing of geological hazards information in East and Southeast Asia. The information system uses the Open Geospatial Consortium (OGC), Web Map Service (WMS) and Web Processing Service (WPS) for spatial data rendition and processing online. Free and Open Source Software (FOSS) is also used for other important spatial data processing and sharing operations. WMS and WPS are formulated to access and view the geological hazard data in the system’s database. The mobile application is developed to access and share the system’s geospatial contents by sending requests to these web services. The application also makes geological hazard mitigation measures more effective by incorporating the mobile device’s GPS location information with geological hazard data. Information like the distance from the nearest active fault, active volcano and earthquake hypocenter can be easily determined using the application. The mobile application provides an interface for the users to easily access geological hazard information such as active fault, active volcanoes, shorelines inundated by tsunamis, and historical and real time seismic events. The widespread use of mobile devices with Internet connection makes geological hazard information dissemination very efficient using the application. The mobile application is called G-EVER Mobile. G-EVER stands for Asia Pacific Region Global Earthquake and Volcanic Eruption Risk Management consortium. The application can be accessed at https://ccop-geoinfo.org/gever-mo/index.php.

Summary
An efficient and highly accessible geological hazard information system is indispensable for an effective geological hazard mitigation endeavor This kind of information system requires the use of Geographic Information System (GIS) software to make it more efficient and cost-effective for spatial information processing, management and storage [1] [2]. The application formulates and sends the web services requests to the Web Services component of a WebGIS to access, render and share the geological hazard information in the system database. This paper presents a mobile application and a WebGIS system developed to efficiently share geological hazard information to the general public. Details of the mobile application, how it is used to formulate the web services requests and share geological hazard information will be presented. The use of the mobile device’s location information to determine the distance between the user and geological phenomena will be illustrated
