Damage[edit]

Over 1000 houses collapsed, 4 people were killed and 300 people were wounded in this earthquake sequence.[5]

Extent[edit]

The 6.0 earthquake could also be felt in Tanzania and Zambia.[6]

Geology[edit]

Being in the southern East African Rift, the 100 km-long Livingstone Fault marks the limit of the Karonga Basin. The earthquakes were about 50 km west of the Livingstone Fault. A research of J. Biggs et al. shows that one of the west dipping faults which cut the Karonga Basin might rupture in the earthquakes.[7]
