Norway's Weird Waves Traced to Japan Earthquake

Source: Live Science

On a calm winter's day in Norway two years ago, the sea suddenly started to boil and rise, sending freak waves rolling onto nearby shores and mystifying residents. Turns out, the massive magnitude-9.0 earthquake that shook Japan in 2011 also triggered these surprise seiche waves, a new study shows.

Seiche (pronounced saysh) waves are standing waves that form in closed or semi-enclosed water basins, such as Norway's narrow, steep-walled fjords. Smaller examples of standing waves include water sloshing in a bathtub from a wriggly child, or in a swimming pool after an earthquake.

The roiling seas surprised and shocked Norwegians when the waves rolled in after 7 a.m. local time on March 11, said lead study author Stein Bondevik, a geologist at Sogn og Fjordane University College in Sogndal, Norway. The waves measured nearly 5 feet (1.5 meters) from trough to crest (their lowest to highest point). No damage was reported, however. "Luckily, they happened at low tide," Bondevik said.

events that have been attributed to methane gas bubbles erupting fast to the surface and causing damage.

Just as some ocean going vessels have been damaged without any weather related or seismic warnings. There was an example of a boat of American students that was damaged.

IDK where I read that, but it was pretty weird stuff and it's not a new thing. Neither are the damage by earth quakes, methane bubbles or tsunamis.

Glad no one was hurt this time by this event.

So much between the two present nations we see as separate, but they never really were. I know the water did part them, but then there's the chunnel.

Always thought that was a bit of a mistake as far as maintaining sovereignty, the more I learned, I came to realize I was all wrong about it. Europe is a fantastically diverse, yet united region, and they've found a way to now live with each other without warfare as in the past and without civil war within the different nations.

A huge accomplishment that was based on years of wars and working things out, but the creativity and determination seemed to have arisen from their pain. Their worst days seem to be behind them.

Just wish the USA would stop playing at not being a country. It's difficult to move forward with our mentality.
