Cloud Computing in natural hazard modeling systems: Current research trends and future directions

Abstract

Every year, natural disasters cause major loss of human life, damage to infrastructure and significant economic impact on the areas involved. Geospatial Scientists aim to help in mitigating or managing such hazards by computational modeling of these complex events, while Information Communication Technology (ICT) supports the execution of various models addressing different aspects of disaster management. The execution of natural hazard models using traditional ICT foundations is not possible in a timely manner due to the complex nature of the models, the need for large-scale computational resources as well as intensive data and concurrent-access requirements. Cloud Computing can address these challenges with near-unlimited capacity for computation, storage and networking, and the ability to offer natural hazard modeling systems as end services has now become more realistic than ever. However, researchers face several challenges in adopting and utilizing Cloud Computing technologies in this area. Moreover, accessing the Cloud services during the disaster where the communication and power supply can break down, is still an open challenge. As such, this survey paper discusses these challenges, needs and existing problems to reflect the current research trends and outlines a conceptual Cloud-based solution framework for more effective natural hazards modeling and management systems using Cloud infrastructure in conjunction with other technologies such as Internet of Things(IoT) networks, fog and edge computing. We draw a clear picture of the current research state in the area and suggest further research directions for future systems.

Development of the SiAlong Platform to Improve Digital Literacy on Landslide Disasters among Generation Z in Semarang City

“…A study by Li et al [116] stated that WEBGIS is one of the appropriate and effective technologies for implementing disaster education. GIS can be useful for creating and presenting spatial processes and analyses, which can then be beneficial for better decisionmaking [117]. GIS has also been widely used for analyzing and mapping hazards, risks, and vulnerabilities, thus facilitating and effectively enhancing understanding and risk management in various areas [118][119][120].…”

Cloud-Enabled High-Altitude Platform Systems: Challenges and Opportunities

“…The authors propose a general architecture of a cloud infrastructure with direct access to satellite data, and discuss the possibilities for bridging professional and home-based satellite receivers into an integrated satellite cloud computing framework. Finally, the authors in Ujjwal et al (2019) describe how the computation, storage, and networking capabilities of cloud computing enable natural hazard modeling systems that utilize Satellite Remote Sensing to achieve accurate results in real-time.…”

Analysis of Earthquake Emergency Command System According to Cloud Computing Methods

“…This system can provide people with escape routes and other help in the event of disasters, greatly improve the reliability and safety of the indoor workplace, and prepare and manage for various emergencies or events [19]. Ujjwal et al (2019) investigated that in the event of earthquake and other disasters, cloud computing and Internet of things technology can be used to more effectively construct natural disaster prediction model and management system [20].…”
