However, since potential risks are related to structural locations and community development, they can be evaluated more accurately. The second most important achievement of IIPLR is community land use. Its purpose is to promote the placement of buildings in areas of high risk of being exposed to floods, hails, fires of the wilderness, earthquakes and storms. Land use policies and decision makers need to understand the vulnerability of individual assets against natural disasters and consider the vulnerability in land use, development and construction decisions. Consumers (owners and developers) need to be educated about natural disasters related to construction sites and use this information when selecting such places. IIPLR works with other partners to develop incentives for not building or using special mitigation techniques in high-risk areas.
The aim of natural disasters and risk assessment is to determine the extent and nature of the risk in a particular field by evaluating the risks that may harm the destruction of people's property, goods and services (UNISDR , 2009). Various studies have found that society is increasingly vulnerable to disasters due to the increase in population in dangerous areas and increased economic and environmental pressure (Rougier et al., 2013). The socio-economic and physical impact of volcanic ash on the environment is obviously large. Through years of research and observation, the understanding of the past 30 years has been significantly improved (eg Soufrière Hills (Montserrat), 1995; Eyjafjallajökull (Iceland), 2010) (Vervaeck, 2012). The current impacts associated with volcanic eruption have allowed interdisciplinary research on volcanic ash. The purpose of this research is to examine the formation, migration, and effects of Mayan Shan volcanic eruption in 2014.
