Question: The Buckner Building in Whittier Alaska withstood what natural disaster that claimed 139 lives?
Context: The Alaska Railroad (reporting mark ARR) is a Class II railroad which extends from Seward and Whittier, in the south of the state of Alaska, in the United States, to Fairbanks (passing through Anchorage), and beyond to Eielson Air Force Base and Fort Wainwright in the interior of that state.  Uniquely (for the US), it carries both freight and passengers throughout its system, including Denali National Park.  The railroad has a mainline over 470 mi long and is well over 500 mi including branch lines and siding tracks.  It is currently owned by the state of Alaska.  The railroad is connected to the contiguous 48 via three rail barges that sail between the Port of Whittier, Alaska and Harbor Island in Seattle (the Alaska Railroad-owned Alaska Rail Marine, from Whittier to Seattle, and the CN Rail-owned Aqua Train, from Whittier to Prince Rupert, British Columbia) but does not currently have a direct, land-based connection with any other railroad lines on the North American network.  In 2016, the company suffered a net loss of $4.3 million on revenues of $169.8 million, holding $1.1 billion in total assets. 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. Casualty prediction is the science of predicting the number of deaths or injuries that may result from an epidemic, natural disaster or act of war such as the explosion of a nuclear weapon, chemical weapon or biological weapon.  (Casualty estimation is the process of estimating the number of injuries or deaths in a battle or natural disaster that has already occurred.) The Buckner Building is an abandoned former U.S. military building in Whittier, Alaska.  Designed by Foss, Malcolm and Olsen architects, it was constructed by the military in 1953 as a combined mess hall, sleeping quarters, recreational, medical and administrative facility and used to be one of the largest buildings in Alaska, often being referred to as "the city under one roof".  The building was slightly damaged by the 9.2 1964 Alaska earthquake, though damage was minimized by its reinforced concrete construction. The 1964 Alaskan earthquake, also known as the Great Alaskan earthquake and Good Friday earthquake, occurred at 5:36 PM AST on Good Friday, March 27.  Across south-central Alaska, ground fissures, collapsing structures, and tsunamis resulting from the earthquake caused about 139 deaths. 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. Camp Sullivan was a United States Army camp located in Whittier, Alaska from 1943 to 1960.  Constructed out of a need to supply the region with military support during World War II, the area became important again during the Cold War after the Army decided to build the 14-story Hodge Building (now Begich Towers) completed in 1957 contained 150 two and three bedroom apartments plus bachelor efficiency units.  Dependent families and Civil Service employees were moved into this efficient high rise.  The new Whittier School was connected by a tunnel at the base of the west tower so students could go to school in short sleeves on the very worst weather days.  The building, originally was named in honor of Colonel Walter William Hodge Civil.  Engineer.  the CO of 93rd Engineer Regiment on the Alcan Highway.  The other structure, the Buckner Building, had been completed in 1953, and was called the "city under one roof".  Both buildings were at one time the largest buildings in Alaska.  The Begich Building is now a condominium.  Together with the 2-story Whittier Manor, Begich Building houses nearly all of Whittier's residents.  The port remained an active Army facility until 1960. The Glacier Discovery is a passenger train operated by the Alaska Railroad between the towns of Anchorage, Whittier Alaska and the rail station known as Grandview.  It is a seasonal train, only operating between the months of May and September. 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 Whittier Conservancy is a coalition of citizens in the city of Whittier, California.  It was born from the rubble of the Whittier Narrows earthquake of October 1, 1987, which had led to the destruction of many historic buildings in Whittier, including the Lindley Building, one of Whittier's "Four Bricks", and the landmark Whittier Theater.  In 1989, the Conservancy assisted the City to rezone the residential neighborhoods north of Hadley Street to protect this vital area from rampant, uncontrolled apartment construction.  The Conservancy spearheaded the preservation of the historic Whittier Depot and the McGee House.  Though primarily a historic preservation organization, the Conservancy is also interested in open space preservation, and is involved in the continuing movement to preserve the Whittier Hills as part of the Puente-Chino Hills Wildlife Corridor
