The strongest earthquake to hit southern Africa in over 100 years last night killed two people in Mozambique.
The magnitude 7.5 earthquake was felt as far south as Johannesburg and Durban in South Africa.
The earthquake hit on east Africa's rift system.
The US Geological Survey (USGS) reported at least three significant aftershocks during the night.
Police in Beira denied rumours that a building had collapsed in the city, but British charity Actionaid, which has officials in the area, said at least 13 houses had collapsed.
The earthquake comes after flooding that left 21 dead in central Mozambique in December, while tens of thousands of people lost their homes.
The government in January appealed to international donors for some €16.6m to help it set up a disaster relief programme.
The former Portuguese colony has also been hit by a lengthy drought that has left nearly one million people in need of food aid.
