The 1995 Antofagasta earthquake occurred on July 30 at 05:11 UTC (01:11 local time) with a moment magnitude of 8.0 and a maximum Mercalli intensity of VII (Very strong).

The Antofagasta Region in Chile was affected by a moderate tsunami, with three people killed, 58 or 59 injured, and around 600 homeless.

[5] Slip rate on the fault is 68–80 mm (2.7–3.1 in)/yr, and as a result the subduction zone is responsible for many megathrust earthquakes in the region.

[9][10] At 1:11 local time on July 30, 1995, a large earthquake struck northern Chile.

[13][11][14] Foreshock activity was minimal, but large aftershocks lasted a while after the mainshock, with the largest being a shallower Mw  6.4 event with a Modified Mercalli Intensity of VII three days later.
