This study aimed to identify the degree of awareness about natural disasters among Social Studies' teachers in the Sultanate of Oman, according to gender, specialty and years of teaching experience. In order to achieve the aims of the study, a descriptive research approach was used which involved designing a three-dimension scale: a cognitive test, an affective test, and a behavioural test. The cognitive test was multiple-choice questions with four options while the affective and behavioural tests were based on five points Likert-scale. After establishing the validity and reliability of the scale, it was distributed to (397) Social Studies' teachers from Muscat and Batinah South governorates who constituted the sample of the study. The analysis revealed that the degree of awareness about natural disasters among Social Studies' teachers in the sultanate of Oman was generally moderate with (70%) on average. The participants demonstrated the lowest degree of awareness about natural disasters in the cognitive domain with (53%) while they demonstrated the highest awareness in the affective domain with (80%). The behavioural domain was high with (79%) of degree of awareness about natural disasters. The findings also showed statistically significant differences on (a=0.05) in the degree of awareness about natural disasters in the cognitive test among males and females favoring the females with an average of (2.776). However, there were no statically significant differences in the degree of awareness about natural disasters in respect of specialty and teaching experience. The study recommended working on the improving the degree of awareness about natural disasters among the Social Studies' teachers through organizing seminars, conferences and training workshops.
