The 1989 Salima earthquake struck Malawi at 23:49 local time on March 10, 1989, with its epicenter located near the town of Salima, situated on the shores of Lake Malawi. The earthquake primarily affected the central and northern regions of the country, including areas such as Salima, Kasungu, and Lilongwe, leading to significant damage to infrastructure and homes. The reported fatalities were around 9, with approximately 100 people injured and thousands displaced. Economic losses from the event were estimated at around $28 million USD (at the time of the event), primarily due to damage to buildings, roads, and public infrastructure. Although the earthquake caused widespread destruction, there were no reports of tsunamis, fires, or significant liquefaction. However, landslides were observed in some areas, especially in regions with hilly terrain, contributing to the overall destruction caused by the quake.

The folder OpenQuake_gmfs contains the input files required to generate ground motion fields, considering different rupture solutions and conditioning the ground shaking to the recording stations for the event, where available. The figures below present an example of the results, illustrating the median ground motion fields with and without conditioning. These results are based on the rupture and ground motion model that demonstrates the lowest nominal bias. The maximum recorded Peak Ground Acceleration (PGA) was [insert value here], observed at [insert location here]. If no seismic station data were available for the event, the generated ground motion fields are shown without conditioning to recording stations, as illustrated in the figures.
The information collected for the consequences of the event and the corresponding references is available in the Impact folder. When available, information at different geographical levels is provided considering the building damage, economic losses and human impact.
