Earthquakes are one of the world's worst natural disasters. They collapse buildings and infrastructure while taking lives. Caused by movements of the Earth's crust the energy released causes seismic waves. Some are weak but strong earthquakes can destroy cities. Earthquakes can trigger tsunamis, avalanches, landslides and fires that further take a toll on life and property. The effects of an earthquake and its aftermath are worse in heavily populated areas where more lives may be lost and great damage done to property and the city's infrastructure. Depending on the strength of the earthquake and its geographic location earthquakes can be extremely costly. Some areas of the world have to completely rebuild following an earthquake.
Here are the top 20 costliest earthquakes in world history.
20. San Francisco, California
The San Francisco earthquake of April 18, 1906 is considered to be one of the most significant earthquakes in history. The earthquake and subsequent fires nearly leveled the California and left property damage of $400 million. That is the equivalent to $10.7 billion today. The earthquake had a 7.8 magnitude and lasted 45 to 60 seconds. It occurred along the northern 296 miles of the San Andreas Fault. With the epicenter near the city of San Francisco, the effect of the quake were felt south of Los Angeles, north to Oregon and through central Nevada. The earthquake helped advance building codes for earthquake safer buildings and advanced the science of earthquakes. The San Francisco earthquake triggered fires that burned for 4 days. These were mostly caused by ruptured gas lines and account for the destruction of 90 percent of the damage. 3000 people lost their lives and 80 percent of the city of San Francisco was destroyed. 25,000 buildings were destroyed over 490 city blocks. The damage caused by the earthquake spread to surrounding agricultural areas and to cities including San Jose and Santa Rosa.
The Great Alaska Earthquake struck on Good Friday, March 27, 1964. The 9.2 magnitude earthquake in south central Alaska is one of the strongest ever recorded. It triggered massive tsunamis that affected the entire coast of North America. The cost of the earthquake was over $570 million. The earthquake lasted 4 minutes and killed 15 people. More than 100 would die from the following tsunamis and landslides. An underwater landslide in Prince William Sound collapsed the harbor and docks in the city of Valdez killing 30 people. In the city of Chenega 23 of its 68 residents died in the tsunami. Buildings and infrastructure were heavily damaged and coastal cities were destroyed.
18. Tokyo, Japan
The "Great Kanto Earthquake" shook the main island of Honshu in Japan on September 1, 1923. The 7.9 magnitude earthquake triggered tsunamis and landslides causing further damage to the country. The damage cost over $600 million (that would be $14 billion today). A landslide pushed an entire train, train station and track into the sea. Over 142,000 died with 40,000 reported missing. Along with buildings and infrastructure damage, 570,000 homes were destroyed leaving 1.9 million people homeless. Japan would have more earthquakes including the costliest earthquake in history.
17. Valdivia, Chile
A 9.5 magnitude earthquake with the epicenter near the city of Valdivia, Chile struck May 22, 1960. Several severe earthquakes shook a wide swath of the country of Chile between May 21 and June 6. The damages were about $1 billion (that would be $6 billion today). The "Great Chilean Earthquake" lasted about 10 minutes and set off landslides and widespread tsunamis. Tsunamis reached Hawaii, Japan, the Philippines, New Zealand, Australia and the Aleutian Islands. Tsunamis off Chile's coast reached waves as high as 82 feet. More than 6000 people died. 20,000 people were left homeless in the heavily damaged Valdivia. The damage was widespread and severe through much of the country of Chile.
16. Tangshan, China
On July 28, 1976 at 4 am a 7.8 magnitude earthquake struck the Tangshan region of China. A second strong 7.1 magnitude aftershock followed hours later. The earthquake had the highest death toll of the twentieth century with about 255,000 people killed and 164,000 injured. The high death toll is in part attributed to the suddenness of the earthquake and, because it occurred at 4 am, most people were sleeping and unprepared. The earthquake struck with no warning pre-shocks. The initial earthquake lasted 14 to 16 seconds. Damage was extensive and tremors were felt far from the epicenter throughout China. 85 percent of the buildings in the Tangshan region were completely destroyed. It cost $1.3 billion to rebuild the damages, and the Chinese government at the time refused aid from the United Nations. This was one of the worst earthquakes in Chinese history.
15. Seattle/Tacoma, Washington
Named the "Nisqually Earthquake" after the Nisqually Delta, this earthquake centered in the southern Puget Sound and mostly affected areas including Seattle, Tacoma and Olympia. The 6.9 magnitude earthquake occurred on Ash Wednesday, February 28, 2001 and was felt throughout Washington, Oregon, Canada and Idaho. The damage was $2 billion. Fortunately there was no loss of life due to the earthquake, but there was a lot of property damage and infrastructure damage. Bridges and factories were heavily damaged. The air traffic control tower at Sea-Tac International Airport was damaged. Among the damaged buildings several were at thee Fort Lewis and McChord Air Force Base.
14. Kashmir, Pakistan

The total damage was $5.4 billion. The area was crippled by the earthquake and its aftershocks. Buildings, hospitals and schools were heavily damaged as well as infrastructure. An estimated 85,000 people died and more than 69,000 were injured. Many were left homeless and it took many years to rebuild the area
A 7.8 magnitude earthquake struck Nepal on April 25, 2015 causing $10 billion. The epicenter was the Gorkha District in Barpak, Gorkha and the effects were widespread. More than 5000 people were killed and over 10,000 suffered injuries. Many were left homeless. Many buildings including historically significant buildings and religious sites were destroyed in the worst earthquake to strike Nepal since 1934. The earthquake triggered an avalanche on Mount Everest killing 21 climbers. Another avalanche in the Langtank Valley left 250 people missing. A 7.3 magnitude aftershock caused further damage on May 12.
12. Jiji, Taiwan
On September 20, 1999 Taiwan was hit by a 7.3 magnitude earthquake, the deadliest in the nation since a 1935 earthquake. Known locally as the "921" earthquake it caused $10 billion in damages.
