Abstract

The report gives a brief qualitative review of hazards in the Karahnjukar area due to earthquakes and faults, taking into consideration relevant new geological observations that indicate Holocene faulting in the area. Although the KarahnjUkar area is currently seismically quiet, stress and strain fields in the area may change and revive seismic activity. Faulting may be triggered due to increased pore pressure due to the establishment of Halslon. A significant normal faulting near-field earthquake should be given due consideration. Hazards from the opening of fractures in response to increased pore pressure are considered significant as well.
