Furious Fiords
![Steve's picture Steve's picture](http://openhazards.com/sites/default/files/pictures/picture-1798.jpg)
Who doesn’t marvel at those wonderful travel pictures of the fiords of Norway? Waterfalls, quaint houses perched on green slopes, snowy glaciers far above and likely, a cruise ship sailing far below.
One hesitates to sully this image with negative mentions, but steep-sided fiords do present a real and present danger in the form of rockfalls and rockfall-generated waves. “Fiord tsunami” I call the latter, however some find this liguistic mixture ludicrous as ‘lutefisk sushi’.
Terms aside, rockfalls and rockfall waves are serious business -- many dozens have occurred in historical time. The latest fiord tsunami happened in 1934 just outside of the town of Tafjord. Waves rose up to 62 meters elevation there and 41 persons perished.
The greatest rockfall threat looming today lies on Akerneset Mountain, flanking Sunnylvsfjorden 23 km west of Tafjord. There, a set of ominous cracks gape 900 meters above sea level. The cracks are thought to bound a sliver of mountain maybe 60 million cubic meters in volume that, like others did before, will surely fall into the fiord someday.
My computer simulations in the movie above predict that a fiord tsunami 100 m high would be sourced from a Akerneset rockfall. Not good news for Hellesylt and Geiranger, two pretty towns nestled just four and eleven minutes away by tsunami. The truly scary part of the story is that the crack widths are expanding by 3-20 cm/year.
As you might expect, scientists now closely monitor the landslide region with a battery of instruments. Their hope is that a pre-failure increase in the rate of crack expansion could provide prior warning of an impeding slide perhaps days in advance.
The notion of “Furious Fiords” has not escaped the attention of big-budget moviemakers as fodder for a docudrama/disaster flick. Recently a Norwegian film company released the movie titled “Bolgen” (Norwegian for “Wave”) staring this very same fiord tsunami. Take a look at the teaser…

Thanks for providing such useful information. I really appreciate your professional approach. I would like to thank you for the efforts you made in writing this post.
You really did kill that illustration, very creatively and interestingly done. You are one awesome and gifted dude, like some of the students at BookWormLab reviews who are fond of doing creative simulation samples for their project.

This simulator video of showing fiords tsunami is very good creative presentation, as i have seen it before from rushessay com reviews blogs, and this video show the great danger for that city if anything like tsunami hit that place when can clearly see the falling of rocks and how much destruction those falling rocks can create in that city and change the face of the city in seconds time.
Awesome illustration of furious fiords. You are indeed very talented when it comes to simulation presentations, just like how the staff of BuyEssayOnline.org reviews did their simulation project in the past.
I will always remember how you helped me to get this wonderful opportunity خانه هوشمند

which are the best.
These are some really terrifying scenes shared in the video. I have watched the video and it is quite hard to believe. Unbelievable scenes are being recorded on the same and I am wondering about how they managed to capture those scenes. best internet service consumer triple play

Seeing the video, it seems as a big storm but I think that there are lot of things that can answer my questions that I got from The Academic Papers.
