A procedure for a dip angle determination of a fault plane from gravity field data is presented to
constrain a seismic profile interpretation. This procedure is applied on Mahjouba normal fault at the
western border of Kalaa Khesba graben (Central Tunisian Atlas Province, North Africa). Seismic and
detailed gravity data, in this region, were analyzed to provide more constraints on the geometry of the
fault dip angle. The Mahjouba fault is mapped as three major parallel lineaments extended for 2 kmwith

App Inventor (AI) for Android is a block-based programming environment that enables nonprogrammers to create fully functional mobile applications for Android phones by dragging and dropping code blocks. Since the launch of AI, many improvements were applied to it, which aimed to increase its effectiveness in promoting programming education for beginners. In our workshop, which targeted high school female students, we taught mobile programming using the improved version of AI2 (a free cloud-based tool).
