The 2012 Indian Ocean earthquakes were magnitude 8.6 and 8.2 Mwundersea earthquakes that struck near the Indonesian province of Aceh on 11 April at 15:38 local time. Initially, authorities feared that the initial earthquake would cause a tsunami and warnings were issued across the Indian Ocean; however, these warnings were subsequently cancelled.[5][6] These were unusually strong intraplate earthquakes and the largest strike-slip earthquake ever recorded.[3]
