The 1986 Kalamata earthquake struck the southern Peloponnese region of Greece on September 13th at 20:24 local time. The maximum Mercalli intensity reached VIII. This magnitude 6.0 earthquake, with an epicenter near the coastal city of Kalamata, caused significant damage and loss of life. The city of Kalamata and the surrounding areas were most heavily impacted, with numerous buildings collapsing or sustaining severe structural damage. At least 20 people were killed, and 300 more were injured. Economic losses were substantial, estimated at around 745 million USD. The earthquake triggered numerous landslides, and some localized liquefaction was observed.

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.
