Some interesting landslide sites
Posted by Dave Petley
I thought that it was high time to post a summary of some interesting landslide sites:
There is an interesting youtube video of a smallish progressive rockslide occurring at Aowanda in Taiwan here. It should also be visible below:
Not quite as dramatic as some others, but useful nonetheless.
Five disastrous landslides that changed the Canadian Landscape
There is quite a nice non-scientific piece here that describes in non-technical language five large and significant historic landslides in Canada over the last century or so. Good images!
There is an interesting new blog here that looks at measures that can be used to prevent rockfalls. Although it is in Italian, Google Language Tools do a pretty good job of translating the text. I guess one should be a little careful of the fact that it is promoting a company, but there is some nice stuff there.
The largest known landslide?
National Geographic has a nice story here that speculates that a large deposit on Mars might be the debris from a landslide that would have been the size of the United States. Working on Mars must be great because no-one can check your interpretation with field data.
It is a fine line between a debris-rich flash flood and a debris flow, so I thought that I would highlight this youtube video of a flash flood in Australia. The first minute isn’t terribly exciting, but stick with it! It should be visible below:
Extraordinary video of the Baldwin Hills dam disaster
There is an excellent video of the collapse of the Baldwin Hills dam in 1963 on youtube here. This is a great illustration of the dangers associated with the formation and collapse of landslide dams. Again, it should be visible below:
Dave -Mount Redoubt in Alaska is on the news, and Wikipedia (in its infinitely partially trustworthy glory) speaks of “lahars” or mudflows that happened in its 1989 eruption. Something to have on your radar.thanksEd
Dave, tank you for mentioning my blog (rockfall Blog); I want to underline the fact that the Blog is absolutly independent from any business activity. I mentioned the company I’ve incorporated with a similar name only for transparency against my readers. I’m open to every company that wants to appear in my blog. B.R. Thomas
