It was preceded by a number of foreshocks, the largest being a 5.7 w y shock on the previous day. The earthquake was felt strongly throughout central Malawi, and also felt in parts of Mozambique (Niassa and Tete Provinces) and Zambia (Eastern Province). Nine people were killed, with many others injured or left homeless. Geology The 1989 Malawi earthquake was the result of a dip-slip fault in the Malawi rift system, part of the larger East African Rift. It is believed to have occurred at a depth of about 30 km mi on, with the lack of surface faulting being attributed to its occurrence at a relatively deep level.Jackson James Blenkinsop Tom 1993 The Malawi Earthquake of March 10, 1989: Deep Faulting Within the East African Rift System http://orca.cf.ac.uk/50645/ Tectonics 12 5 1,131–1,139 10.1029/93tc01064 1993Tecto..12.1131J The International Seismological Centre (ISC) placed the epicentre of the 1989 Malawi earthquake at 13.74 S 34.41 E inline, although the accuracy of their determination was affected by the lack of seismic stations in the area – the closest was 300 km mi on away, and there were only two within 900 km mi on. It has been suggested that the margin of error for the epicentre is consequently around 20 km mi on. The earthquake triggered landslides in the Manyani Hills, around 90 km mi on east northeast of Kasungu. Slumping of 2 km mi on in length and 1 km mi on in width was observed, and attributed to heavy rainfall earlier in the year combined with deforestation-related soil exposure. There was also a large rock fall in the Chongomi Mountains of Dedza District, which resulted in hillside scarring. However, both of those areas were sparsely populated, and there were no reported casualties. Damage and casualties Nine people are known to have been killed as a result of the earthquake – six in Dedza, two in Salima, and one in Chitala. At least two of the deaths (one in Dedza and one in Chitala) were caused by roof collapses, in both cases occurring in houses with roofs built from blocks of baked clay (a non-standard method of construction).Gupta Harsh K.

Urban areas were worst affected by the quake, as houses were more likely to be built of brick and thus more susceptible to cracking. The major building with the most visible damage was the Nanjoka Railway Station complex, which developed severe cracks in its walls and was subsequently abandoned. The Chitala Farm Institute, an agricultural school, was also heavily damaged. In rural areas, most dwellings were simple huts, built by pasting mud or clay onto timber frames. These were left mostly undamaged. Aftermath In the same month as the earthquake, Malawi was hit by a cyclone and suffered severe flooding. The combination of natural disasters left over 200,000 people homeless and led to the government appealing for international assistance.Kalley Jacqueline Schoeman Elna Andor Lydia Eve 1999 Southern African Political History: A Chronology of Key Political Events from Independence to Mid-1997 https://books.google.com/books?id=oVrVK2ElINMC Greenwood 190 978-0313302473 A field study conducted in October 1989 concluded that the March 1989 earthquake "should be treated as an eye opener, drawing attention to the potential of medium-size earthquakes hitting major cities in Malawi".Gupta Harsh K. 1992 The Malawi earthquake of March 10, 1989: a report of the macroseismic survey Tectonophysics 209 1 165–166 10.1016/0040-1951(92)90018-2 1992Tectp.209..165G free References External links M 6.2 – Malawi – United States Geological Survey 409791 Category:Earthquakes in Africa Category:Natural disasters in Malawi Malawi earthquake, 1989 Malawi earthquake, 1989 Category:March 1989 in Africa
