Here is a look at the 10 deadliest earthquakes over the past 100 years after two massive quakes claimed more than 50,000 lives in Türkiye and Syria.
The devastating earthquakes that shook Türkiye and its neighbour Syria on February 6 did not stop right away: numerous aftershocks followed, killing more than 50,000 people across two countries and flattening buildings in 11 southern Turkish provinces as well as in northern Syria.
The Türkiye quakes went down in history as "disaster of the century" for the region and are among the ten deadliest earthquakes of the past 100 years.
1976: 242,000 dead, China
A quake measuring 7.8, according to the Chinese authorities, (7.5 according to the US Geological Survey), strikes near the industrial city of Tangshan in northeastern Hebei province. The official death toll is given as 242,000 but is believed to be significantly higher.
Western experts put the toll as high as 700,000, which would make it the second deadliest in the history of mankind, after the huge 1556 disaster that struck northern Shaanxi province, with estimates of the toll put at more than 830,000 people.
2004: 230,000 dead, southeast Asia
On December 26, 2004, a massive 9.1-magnitude earthquake strikes off the coast of Sumatra, triggering a tsunami that kills more than 230,000 people throughout the region, including 170,000 in Indonesia alone.
Waves 30 metres (100 feet) high, travelling at 700 kilometres per hour (435 miles per hour), swallow everything in their path.

A magnitude 7 quake on January 12, 2010, devastates the capital Port-au-Prince and the surrounding region.
The quake cuts the country off from the rest of the world for 24 hours, killing more than 200,000 people, leaving 1.5 million homeless and shattering much of Haiti's frail infrastructure.
In October the same year, Haiti is also hit by a cholera epidemic introduced by Nepalese peacekeepers who arrived after the quake. It kills more than 10,000 people.

More than 87,000 people, including thousands of school pupils, are left dead or missing when a 7.9-magnitude quake strikes China's southwestern Sichuan province on May 12, 2008.
The quake causes outrage after it emerges that 7,000 schools were badly damaged, triggering accusations of shoddy construction, corner-cutting and possible corruption, especially as many other buildings nearby held firm.
