Digital library, also known as a digital repository, focuses on collecting digital objects such as visual materials, visual videos, and text and audio material stored in the form of electronic media formats. The library provides means of keeping, organizing and retrieving information contained in the media collection. Digital library has many uses such as it can be used by people to access information at any time and any place. The library can also be used to access primary information sources and support multimedia content together with the text. Other uses of digital library include accessibility of network on intranet and internet, provision of user-friendly interface and hypertext links for navigation. Moreover, the library is useful when carrying out advanced search and in retrieval of information. In addition, it is easier to link with other digital libraries which can act as a server for clients doing architectural work (Papy, 2010).
The Geological Hazard Mapping website actively identifies, assess, and maps hazards caused by geological features by use of geophysics and geotechnical instruments. The hazard map is very crucial during emergency-planning management, response to disasters and in designing code amendment for land use. There is the observation that when population continuous to grow, pressure builds on hazardous areas and geologist use the information to educate the people under the Growth Management Act, about the dangers of settling in these regions. The website can detect earth movements such as earthquakes, volcanoes, landslides and tsunamis (Castleton, Elliott & McDonald, 2011).
In response to geological hazards, new technologies continue to emerge such as Advanced National Seismic Systems for detecting earthquakes in timely data and measuring their extent of damage on buildings and structures. In addition, there is innovation of remote sensing technology for monitoring, assessing and analyzing the geological hazards (Castleton, Elliott & McDonald, 2011).
