[00:08] Hillsides, mountains, canyons and coastlines are under increasing development pressure as Earth's human population grows, and more people move in to these areas known for their scenic beauty.

[00:19] Unfortunately, many of these regions are as dangerous as they are breathtaking; highly susceptible to erosion and collapse from natural hazards such as volcanic eruptions, and earthquakes; human land alterations; and extreme weather.

[00:33] Along the California coast, wind-driven waves, abnormally high sea levels and heavy rains battered fragile sea cliffs and beaches during the El Nino events of 1982 and 1997.

[00:46] Many buildings placed directly on exposed beaches, or too close to rapidly retreating cliffs were destroyed, damaged or threatened.

[00:54] Despite the obvious danger, however, people continue to literally live on the edge.

[00:59] As Earth's climate warms, many scientists expect extreme weather events, including the kind causing landslides, to become more common.

[01:07] Better planning can help people learn to live in harmony with nature rather than defy its powers.

[01:13] Historical climate data, sea level records, measurements of slopes, and maps of vegetative cover are being combined to pinpoint spots especially vulnerable to landslides. Decisions on uses of those lands could prevent future loss of life and property.
