DISASTERS include both catastrophic accidents and natural disasters that claim a large number of lives or are otherwise significant. BC is particularly prone to certain types of natural disasters because of the nature of its CLIMATE and terrain (see PHYSICAL GEOGRAPHY). Coastal areas experience heavy rainfall and severe Pacific storms that imperil shipping. The Interior is characterized by steep mountain slopes, high snowfall and unstable rock formations, all of which contribute to LANDSLIDES and AVALANCHES. Seismic activity regularly occurs in the coastal MOUNTAINS, and shifting tectonic plates both on- and offshore pose the threat of a massive EARTHQUAKE, perhaps the greatest natural disaster of all. Disaster response activities are coordinated by the provincial government's Provincial Emergency Program (see also SEARCH AND RESCUE).

The list that follows is only a sampling of some of the worst disasters that have occurred in BC.
