By the grace of God, six specialized and comprehensive scientific encyclopedias have been completed. They relate to the history of science in general and the relationship of earth sciences in particular to space, the environment, water, mining, energy, and natural hazards. These encyclopedias, supported by images and illustrations, aim to serve researchers, general education and university students, and all segments of society. Given the scarcity of Arabic references in this field, the encyclopedias specifically cover six areas: The fourth encyclopedia, with 1,112 pages, covers everything related to natural hazards, their management, and how to deal with them and reduce their risks, focusing on earthquakes, volcanoes, tsunamis, floods, landslides, desertification, and drought, and their role in affecting the Earth's structure and environment.
