Congress finds the following:
(1)
While landslides can and do occur in every State and territory of the United States, the type, including sink holes, ground fissures, and subsidence, the severity, and frequency of landslides vary from place to place, depending on the terrain, geology, seismicity and climate.
(2)
Landslides in the United States cause an estimated $3,000,000,000 in damage each year, and that estimation could be improved through better tracking of landslide occurrences and losses.
(3)
The most recent official estimate of deaths from landslides in the United States was in 1985, and it found that landslides kill an estimated 25 to 50 people each year.
(4)
On March 22, 2014, a massive landslide near Oso, Washington, killed 43 people, engulfed 42 homes, and severely damaged public infrastructure and private property.
(5)
There is no collective landslide inventory for most counties, States, or the United States, nor is there an agreed-upon methodology for creating one, since the availability of Light Detection and Ranging (LIDAR), a powerful tool for creating landslide inventories, is uneven and the quality is highly variable.
(6)
Because landslide hazard analysis continues to evolve, developing analysis methods is an important element of technical assistance for nongovernmental entities and State and local governments.
