On 13 May 2014, an explosion at a coal mine in Soma, Manisa, Turkey, caused an underground mine fire, which burned until 15 May.
 In total, 301 people were killed in what was the worst mine disaster in Turkey's history.
 The mine, operated by coal producer Soma Kömür İşletmeleri A.Ş.
, suffered an explosion, the cause of which is still under investigation.
 The fire occurred at the mine's shift change, and 787 workers were underground at the time of the explosion.
 After the final bodies were pulled from the mine on May 17, 2014, four days after the fire, the Minister of Energy and Natural Resources Taner Yıldız confirmed the number of dead was 301.
 Disaster and Emergency Management Presidency (AFAD) announced the names of 301 workers who died in the mine disaster and 486 people who survived but some politicians claimed that the number of dead is more than 340.
The Benwood Mine Disaster was a coal mine explosion that occurred on Monday, April 28, 1924, at the Benwood Mine of the former Wheeling Steel Corporation steel mill located in the city of Benwood in Marshall County, West Virginia.
 The explosion claimed the lives of 119 coal miners.
 There were no survivors.
 It is the third worst coal mining disaster in the state of West Virginia after the Monongah Mine disaster of December 6, 1907 that claimed the lives of 361 miners and the Eccles Mine Disaster of April 28, 1914 that claimed the lives of 183 miners.
The Ferris-Haggerty Mine Site was one of the richest components of the Grand Encampment Mining District in Carbon County, Wyoming.
 The site was first exploited by Ed Haggerty, a prospector from Whitehaven, England, in 1897 when he established the Rudefeha Mine on a rich deposit of copper ore.
 Haggerty was backed by George Ferris and other investors, of whom all but Ferris dropped out.
 The partners sold an interest to Willis George Emerson, who raised investment funding for improvements to the mine.
 These facilities included a 16 mi aerial tramway from Grand Encampment over the Continental Divide to the in Encampment.
 The mine's assets were eventually acquired by the North American Copper Company for $1 million.
 By 1904 the mine had produced $1.4 million in copper ore, and was sold to the Penn-Wyoming Copper Company.
 However, even with copper prices peaking in 1907, the company had difficulty making a profit from the remote mine site.
 The company was over-capitalized and under-insured and was suffered devastating fires at the mine site in March 1906 and May 1907 which halted production.
 Business disputes and a fall in copper prices prevented re-opening of the mine even after it was rebuilt.
 Machinery was salvaged after a foreclosure in 1913.
 A total of $2 million in copper ore was extracted from the mine during its life.
Barton Mine, also known as Net Lake Mine, is an abandoned surface and underground mine in Northeastern Ontario, Canada.
 It is located about 0.50 km north of the Temagami Arena in Temagami North and just east of the Ontario Northland Railway in northwestern Strathy Township.
 Dating back to the early 1900s, it is one of the oldest mines in Temagami.
 Barton was the site of a fire in the early 1900s, after which it never had active mining again.
INTERSOS is a non-profit humanitarian aid organization that works to assist victims of natural disaster and armed conflict.
 INTERSOS has operated as an independent organization since its foundation in 1992, its humanitarian actions are based on values of solidarity, justice, human dignity, respect for diversity, and equal rights and opportunities for all people, especially the most vulnerable.
 Through its own humanitarian operators, INTERSOS intervenes to answer the needs of people in serious crises situations, mainly in the world's poorest regions, who are suffering, deprived of rights, dignity and essentials goods.
 A Mine Action Unit was established within INTERSOS to deal specifically with the mine danger and its effects through mine awareness, victims assistance and mine clearance operations.
The Sago Mine disaster was a coal mine explosion on January 2, 2006, at the Sago Mine in Sago, West Virginia, United States, near the Upshur County seat of Buckhannon.
 The blast and collapse trapped 13 miners for nearly two days; only one survived.
 It was the worst mining disaster in the United States since the Jim Walter Resources Mine disaster in Alabama on September 23, 2001, and the worst disaster in West Virginia since the 1968 Farmington Mine disaster.
 It was exceeded four years later by the Upper Big Branch Mine disaster, also a coal mine explosion in West Virginia, which killed 29 miners in April 2010.
A natural disaster is a sudden event that causes widespread destruction, lots of collateral damage or loss of life, brought about by forces other than the acts of human beings.
 A natural disaster might be caused by earthquakes, flooding, volcanic eruption, landslide, hurricanes etc.
 In order to be classified as a disaster, it will have profound environmental effect and/or human loss and frequently incurs financial loss.
A natural disaster is a major adverse event resulting from natural processes of the Earth; examples include floods, hurricanes, tornadoes, volcanic eruptions, earthquakes, tsunamis, and other geologic processes.
 A natural disaster can cause loss of life or property damage, and typically leaves some economic damage in its wake, the severity of which depends on the affected population's resilience, or ability to recover and also on the infrastructure available.
The Camlaren Mine was a small gold mine 80 km north-east of Yellowknife, Northwest Territories, Canada at Gordon Lake.
 It consists of a property totaling about 981 hectares.
 The two claims that make up the property were staked in 1936 by prospectors Don Cameron and the Mclaren brothers and developed with two shafts during 1937-1938.
 The name "Camlaren" is a portmanteau of Cameron and McLaren.
 Conditions attributed to World War II halted development at Camlaren in 1939.
The ‘’’Volcano Disaster Assistance Program’’’ (VDAP) was developed by the U.S. Geological Survey and U.S. Office of Foreign Disaster Assistance after the eruption of Nevado del Ruiz (Colombia) in 1985.
 The volcanic eruption melted a glacier triggering a lahar that killed 23,000 people.
 It was determined that increased monitoring and enhanced communications between scientists and civil authorities would make evacuating local populations much easier, saving lives.
 Today the program responds to volcanic crises around the world.
 The aim of the program is to assist in saving lives and property, to reduce economic losses, and to prevent a natural hazard becoming a natural disaster.
 VDAP staff members are based at the USGS Cascades Volcano Observatory, in Vancouver, Washington.
 VDAP channels its energy into four main activities; response to natural disaster, capacity building, training and volcanological research.
