2003 Boumerdès earthquake

The 2003 Boumerdès earthquake occurred in northern Algeria. The shock had a moment magnitude of 6.8 and a maximum Mercalli intensity of X (Extreme). Approximately 2,266 people died, 10,261 injured, and 200,000 left homeless as a result of the earthquake. The quake was the strongest to hit Algeria in more than twenty years - since 1980, when a magnitude 7.1 earthquake resulted in at least 2,633 deaths.

Gustav Lindenthal was born

Born in Brünn, Austrian Empire (now Brno, Czech Republic), civil engineer Gustav Lindenthal is known for designing the Queensboro and Hell Gate bridges in New York City, among other bridges. Additionally, Lindenthal's idea of the bridge not having to carry the full train load allowed bridge designers to create bridges that were still stable, but at the same time much lighter and cheaper.

Gaspard-Gustave de Coriolis was born

Gaspard-Gustave de Coriolis was a French mathematician, mechanical engineer and scientist. He is best known for his work on the supplementary forces that are detected in a rotating frame of reference, leading to the Coriolis effect. He was the first to apply the term travail (translated as "work") for the transfer of energy by a force acting through a distance.

1792 Unzen landslide and tsunami

The 1792 Unzen landslide and tsunami resulted from the volcanic activities of Mount Unzen. This caused the collapse of the southern flank of the Mayuyama dome in front of Mount Unzen, resulting in a tremendous tsunami, killing 15,000 people. Out of the estimated 15,000 fatalities, around 5,000 are thought to have been killed by the landslide, around 5,000 by the tsunami across the bay in Higo Province, and a further 5,000 by the tsunami returning to strike Shimabara. The initial wave once reached a height of 330 ft (100 m), classing this tsunami as a megatsunami.
