While the death toll and size of an earthquake can provide logistical data, other factors influence the devastation victims face and the rate they can recover. For communities already struggling, these disasters can be particularly devastating. Ranked below are the 15 worst earthquakes and the human toll of each.

15 Worst Earthquakes

1. Haiti (2010): At the top of the list of 15 worst earthquakes and the human toll, Haiti suffered an initial 7.0 magnitude quake followed by two aftershocks killing 316,000 people. Due to a lack of adequate reinforcement, buildings across the country crumbled. A loss of power and phone lines interfered with efforts to provide aid. After nine years, Haiti still attempts to repair itself.
2.  Nepal (2015): After crumbling landmarks and 10-story buildings, a 7.8 magnitude earthquake added landslides and avalanches to its path of destruction. An estimated 9,000 citizens died and 22,000 more suffered injuries. More than 600,000 people lost homes and began facing extreme poverty. However, its government and humanitarian organizations responded quickly. Temporary education centers and shelters helped the displaced, and over the last three years, facilities are recovering.
3. Sumatra, Indonesia (2004): The 9.1 magnitude disaster in the Indian Ocean produced severe casualties and devastation. The earthquake itself likely killed 1,000 but the tsunami that followed left 227,898 dead or missing. Because of the short time span between the earthquake and tsunami, no one could create separate death tolls. Indonesia had damages of $4.4 million.
4. Sichuan, China (2008): Whole villages lay flattened after a massive 7.9 quake. Schools and other facilities collapsed, trapping people inside. Estimates determined there were around 90,000 dead, 5,300 of them being children attending class. Buildings injured an estimated 375,000 more citizens and rescue teams attempted to find missing children after the chaos.
5. Tohoku, Japan (2011): An unfortunate 15,703 deaths occurred after an earthquake and tsunami struck the east coast of Japan. The total economic loss racked up to $309 billion to provide reconstruction and services. A nuclear power plant near Okuma suffered damages to its reactors, causing a radiation leak. Thanks to evacuation efforts, the leak did not harm anyone. Several fires occurred after and the event destroyed docks.
6. Izmit, Turkey (1999): Lasting less than a minute, an earthquake striking southeast Izmit left 17,000 dead and 500,000 homeless. Thousands of buildings and an oil refinery were among the destruction. There was a large outcry of people persecuting contractors for their poor workmanship and their use of cheap materials. Authorities found very few of them guilty, however. The 7.4 magnitude earthquake caused an estimated $3 to 6.5 billion in damages.
7. Rudbar, Iran (1990): A 20,000 square mile earthquake devastated homes and farms at midnight. An estimated 50,000 people died and 135,000 injured, some living in simple houses that lacked support. An aftershock the following day caused a dam to burst, adding to financial losses and further loss of farmland. Estimates determined that the reconstruction of the region cost $7.2 billion.
8. Kashmir, Pakistan (2005): Kashmir, the disputed area between India and Pakistan, suffered a loss of 80,000 people after a magnitude 7.6 earthquake. Four million others became homeless. Sections of towns completely slid off sides of cliffs; landslides also created a blockade for relief workers. In addition, the fact that it occurred just before winter worsened the conditions of those seeking shelters.
9. Mexico City, Mexico (1985): Mexico City fell to chaos when 400 buildings crumbled, and the power and phone systems blacked out. Public transportation also halted, leaving panicked citizens without communication or instructions. An estimated 250,000 people were without shelter, and a final death count totaled 10,000.
10. Yunnan, China (2014): Around 4.7 in magnitude, this earthquake killed 398 citizens. The earthquake injured an estimated 1,000 people and displaced over 200,000. Several homes and infrastructure susceptible to earthquakes faced damages as well. The Committee for Disaster Reduction had issued its highest-level response to provide aid: emergency responders prioritized search-and-rescue and the organization directly allocated resources for this purpose.
11. Puebla, Mexico (2017): A 7.1 magnitude earthquake struck central Mexico on the anniversary of its 1985 earthquake. Since the 1985 quake, people underwent earthquake drills which helped limit the damage in the 2017 earthquake although 225 deaths still occurred. Additionally, the earthquake damaged buildings and Mexico had to evacuate its people. Nearby, homes had also crumbled.
12. Norcia, Italy (2016): After suffering multiple previous quakes in a short timeframe, another 6.2 magnitude earthquake occurred between two towns: Norcia and Amatrice. Numerous aftershocks, magnitudes 5.5 through 7 then followed. Because of its unfortunate location between cities and mountain villages, the quake took 247 victims. Rubble from mountains trapped others and blocked roads.
13. Ecuador (2016): After this earthquake, 100,000 people needed shelter, 6,000 suffered severe injuries and 700 died. The earthquake destroyed schools and homes along with health care facilities. Flooding following the crisis worsened an outbreak of the Zika virus, but World Vision helped lessen its impact. It provided information on mosquito control and provided activities to teach sanitation in order to prevent the spread of Zika.
14. Balochistan, Pakistan (2013): The largest province in Pakistan, Balochistan felt an immense tremor from an earthquake with a 7.7 magnitude. Awaran, one of six districts affected, lost 90 percent of its houses. The death toll stood at 328 with more than 440 wounded. Excessive mud that the earthquake brought in buried food, water and houses.
15. Chile (2010): In 2010, a severe 8.8 magnitude earthquake damaged 400,000 homes. Copper production, crucial to Chile’s economy, halted until power resumed. Including loss of exports, the damages totaled $30 billion. The government estimated that the earthquake directly affected 2 million people, while another 800 had died.

Sporadic and unrelenting, earthquakes affect both coastal and inland areas. However, all of the 15 worst earthquakes and the human toll experienced in each have a uniting factor in that they received aid. Despite the severity, government programs and humanitarian bodies rushed to the scene, supplying temporary homes and rations to those suddenly without a place to live. Also, even though most major cases take years to restore themselves, organizations and governments often do not stop giving aid.
