1960 Agadir earthquake
The 1960 Agadir earthquake occurred on 29 February at 23:40 Western European Time near the city of Agadir, located in western Morocco on the shore of the Atlantic Ocean. Despite the earthquake's moderate Mw scale magnitude of 5.8, its relatively shallow depth (15.0 km) resulted in strong surface shaking, with a maximum perceived intensity of X (Extreme) on the Mercalli intensity scale. Between 12,000 and 15,000 people (about a third of the city's population of the time) were killed and another 12,000 injured with at least 35,000 people left homeless, making it the most destructive and deadliest earthquake in Moroccan history.

The Piedra Movediza (Moving Stone) of Tandil falls and breaks
La Piedra Movediza ('Wobbly stone') was a balancing rock located in Tandil, Buenos Aires Province, Argentina. Its weight was about 300 tons. It was particularly interesting not only because of the way it balanced on the face of the hill, but also because it rocked from morning to evening in a very slow fashion (imperceptible to the eye). The stone fell and broke on 29 February 1912.
