When an asset is no longer useful, it should be sold, traded, or discarded. The first step in recording the disposal of a plant asset is to update depreciation. Updating depreciation involves recording the depreciation expense for the time between the date on which depreciation was last recorded and the disposal date.
The largest mudslide in recorded history occurred just 140 miles south of Oso, on the slope of Mount St. Helens, when the volcano erupted in May 1980. The intense heat from the eruption instantly turned more than 70% of the snow and glacial ice on the mountain to water.
However, sometimes damage caused by a mudslide can take days or even weeks to surface. An example of this 'delayed triggering' of deeper landslides occurred in Los Angeles, Calif., in 1998, when mudslides forced the evacuation of more than 100 people and destroyed several houses five days after the rain had stopped, according to the California Geological Survey (CGS).
