Flood and earthquakes are the recent main natural disasters that have caused major treats to life of people and national economy in Malaysia. Both natural episodes have drawn significant intention to governments, industrial and international organization for synergizing in promoting national risk management and enhancing the potentiality to mitigate the impact at the highest possible. Based on the concept of Digital Earth, multi-platform resource and information of earth science data warehouse supported by grid and cloud technologies have created a digital online hub connecting to various networks of digital repositories over the world. Challenges of digital earth for natural disaster application are (a) different spatial and temporal resolution acquired from different platform and data processing tools that minimises the interoperability routines; (b) various data policy and security practices at national and international organization and the industry reducing the potential of data sharing; (c) sparse, redundant and doubtful quality of data handling for integration. This paper reviews the abovementioned challenges in digital earth application and its future opportunity in regards to the Industrial Revolution 4.0 and Sustainable Development Goal (SDG) as well as to national agenda (TN50). Proposed synergy between national, international and industry organization in digital earth application is highlighted. Exclusive research idea and potential related to flood and earthquake are also presented.
