Seismicity of the Neom megaproject area, Northwestern Saudi Arabia

A new seismicity map has been developed for Neom megaproject in the north-western zone of Saudi Arabia which has experienced considerable earthquake activity in the historical and recent times. The data used an up-to-date earthquake (Mw ≥ 3.0) catalog, major structures and tectonic trends. The major...
