| Natural hazards such as volcanic eruptions, earthquakes, and mudflows present a significant risk to the population of the surrounding area. |
|
| Heavy earth-moving equipment sent in to clear the mudflows are failing to make headway as torrential rains continue to fall in the region. |
|
| Even scarier and more destructive than volcanic mudflows are pyroclastic flows or glowing avalanches. |
|
| The center said there were 43 mudslides, most of them located in Nantou County, where the seismic activity has made the county prone to mudflows. |
|
| Thirty-six million years ago, volcanic mudflows blocked a stream flowing through this valley, producing a lake about twelve miles long. |
|
| Since then, the mountainous county has been prone to mudflows and landslides triggered by torrential rains. |
|
| The village has been buffeted by mudflows, landslides, river debris, flooding and earthquakes. |
|
| Rocks block the highway in various places and mudflows cover what were once rose farms along the road's edge. |
|
| Still, it was not until 1996 that the government began to identify specific areas threatened by potential mudflows and landslides. |
|
| Unconsolidated deposits of ash may eventually mix with water to become massive, quick-moving mudflows, called lahars, that can fill in small valleys. |
|
| The U.S. Geological Survey says mudflows from Mount Rainier would be the primary hazard to communities in the valley, including Orting, Sumner, Puyallup and Fife. |
|
| Rescue work continued yesterday in remote Taoshan Village, where more than 20 houses were engulfed by floods and mudflows within minutes on Wednesday. |
|
| Depending on the proportion of water to volcanic material, mudflows can range from soupy floods to thick flows that have the consistency of wet cement. |
|
| As the melting ice weakens the mountains, Switzerland is already experiencing more rockfalls, landslides, and mudflows, but things could get much worse. |
|
| When the glacial ice on Mt. St. Helens rushed down the sides of the mountain and created mudflows, potential energy in the ice became active and major changes took place. |
|
| On June 15, Mount Pinatubo spewed ash 40 km into the air and produced huge ash flows and mudflows that devastated a large area around the volcano. |
|
| Rieber proposed a more elaborate scenario, which included the animals dying of thirst or starvation, and being concentrated by mudflows. |
|
| Landslide lakes are lakes created by the blockage of a valley by either mudflows, rockslides, or screes. |
