Geography · Geomorphology and Tectonics

With reference to the Himalayan Frontal Fault (HFF), consider the following statements: I. It marks the tectonic contact between the Siwalik belt and the Indo-Gangetic alluvial plains. II. It is regarded as the youngest and among the most active thrusts in the Himalayan tectonic framework. III. It reflects the continuing convergence in which the Indian Plate is being driven beneath the Eurasian Plate. IV. Its relative continuity without major seismic gaps suggests a lower likelihood of great earthquakes. How many of the statements given above are correct?
