1999 Vargas, Venezuela Mudslide

Conditions Include:

Rocks, debris, and earth move down a slope. Mudslides usually occur on steep slopes and may be activated by earth’s disasters. Areas where vegetation has been destroyed on slopes can easily become mudslides when wet.

Water quickly collects in the ground and follows in a surge of water-saturated rock, earth, and debris.

How Does This Harzard Form?

Wildfires and humans have destroyed vegetation making more mudslides occur. Steep slopes, bottom of a slope or canyon, water flow near channel, areas where mudslides have occured, undirected surface runoff, or alternated slopes are usually where mudslides happen.

Risk locations

Our specific location was greatly affected by the mudslide. About 20,000 people were killed.

What technology is being used to reduce the impact in the future?

Agencies use regulatory measures to control who use the land. LiDAR data and hyperspectral data sense mudslides. Satellites and thermometers are being used to figure out when mudslide may be present. Geographic Information Systems (GIS), Meteorological Forecast, Environmental Assessment (EA), Institutional Building for Collaboration and Coordination, and Social Assessment (SA) are also used to prevent hazards.

What is the expense associated with the prevention/prediction of this hazard?

It costs money to be protected from a mudslide. People may want to leave their home, so go buy travel tickets. Saving food and supplies can be hard to do. The ground needs to fertile and wanting the water it receives, so people have take care of the land. Lasting, people might try to put up barriers to protect themselves from landslides.

Technology being tested to reduce the impact of a mudslide:

Blom operate similar plant reservoirs. Also, rain, wildfires, earthquakes, volcanic eruptions, and thawing/freezing results in this hazard. You can use the technology used for those hazards to figure out when a mudslide occurs.

Global and national

impact of this hazard:

Cleaning up after a mudslide costs a lot time and money so all over town people try to help. Mudslides are basically national.
