The mainshock had a maximum intensity assigned VIII–IX on the European macroseismic scale (EMS), and an estimated moment magnitude of 6.2–6.4 Mw .

Southern Spain is located within a zone of compression caused by the complex convergence between the Nubian and Iberian plates.

[2] Prior to the mainshock in August, a strong earthquake was also reported in the region on 13 January 1804.

[3] Based on the macroseismic data available, the approximate epicenter would likely be in the Alboran Sea or near the heavily damaged town of Dalías.

In the flat plains, heavy damage was reported, many buildings were left in a state of ramshackle.

[6] The city of Almería was subjected to VII intensity shaking, causing buildings to crack.

Many residents became fearful, and the local government had to impose new regulations to maintain orderly conduct.

St Stephen's Day festivities were prohibited due to debris on the streets.

Collapses also occurred in Roquetas de Mar, where the seismic intensity was evaluated to be VIII.

[5] The heavy losses resulted in the government granting tax exemptions to the populations of Almería, Berja, Dalias, Vícar, Roquetas, Canjáyar, Adra, Ugíjar, Motril and Turón.
