The 2006 Mozambique earthquake occurred at 22:19 UTC on 22 February. It had a magnitude of 7.0 on the moment magnitude scale and caused 4 deaths and 36 injuries. The epicenter was near Machaze in Manica Province of southern Mozambique, just north of the Save River. It was the largest historical earthquake in Mozambique and the first earthquake in southern Africa to have an identified surface rupture.[3]

Tectonic setting

Southern Mozambique is at the southern end of the

Nubian Plate at a rate of several millimetres a year at the latitude of this earthquake. Most earthquakes in this zone are a result of either normal or strike-slip faulting
.

Earthquake

Focal mechanism diagram for the earthquake

The earthquake was felt throughout Mozambique and over a wide area of eastern southern Africa, including

Mercalli intensity scale.[5] In the cities of Beira, Inhambane and Maputo
the intensity reached V.

The

Interferometric synthetic aperture radar (InSAR), combined with field and seismological observations, have identified two fault segments with slightly differing strikes, with the hypocenter and most of the displacement being on the more southerly of the segments.[6]

Damage

Little damage was recorded, with only 294 buildings reported as damaged in the area between Espungabera, Beira and Chimoio.[5] A total of four deaths were recorded, one in Espungabera, one in Machaze and two in Beira, with a further thirty-six injured.
