An earthquake measuring 8.0 Mw  struck Santiago, Chile, on 3 March 1985, killing 177 people and injuring about 2,575 others.

[3] Many landslides were registered too, pavement breaks with the destruction of the Pan-American Highway in several points, broken-down bridges and considerable damage in affected town's infrastructure, with a long interruption on basic services.

[4] Reports by local residents in the coastal area from Matanzas to several kilometers north of Algarrobo indicated unusually low tides for a period of 3 to 5 days following the earthquake.

[citation needed] Meaning that there is an expectation that a similar earthquake will happen in Chile in the future every 25 years.

The precautions that Chile takes now in order to mitigate future risks is to educate its citizens in drills on how to react, having better building codes, and studying seismic data.
