An international team of scientists digging in a sea cave in Indonesia has discovered the world’s most pristine record of tsunamis, a 5,000-year-old sedimentary snapshot that reveals for the first time how little is known about when earthquakes trigger massive waves.

Aftershock rattles Japan’s Fukushima region

A Mw 6.9 aftershock shook the Iwaki region of the coast of Japan on November 22, 2016. Considered an aftershock, since it was within 2 rupture lengths of the  2011 Great East Japan earthquake that itself ruptured a 300 km stretch of seafloor, this is just the latest shaker of the hundreds of quakes >Mw 4 that have occurred since March 11th, 5 years ago. While on the human timescale, there has been enough time for many structures to be rebuilt and life to return to normal for many, geologically speaking the M9 quake is still reasonably fresh. While aftershocks DO get more spaced out in time since the main shock, they do not necessarily become weaker and so this is unlikely to be the last tremor of this magnitude in the area.

Four years later, debris continues to wash ashore on Haida Gwaii and the BC Coast from the 2011 Japanese tsunami. This week, Prince Rupert and Terrace residents listened to two experts talk about the severe impact the tsunami is continuing to have.As waves crash against BC’s Northern Shores, more debris is being discovered says Shoreline Cleanup Manager Kate Le Souef.

“The quantity of debris that we’re finding on the coast line is probably what is the most shocking. So, for example we pulled 4 tonnes of debris off the West Coast trail just in a day of cleanup.”

However, its not just tsunami debris, but from everyday activities says Le Souef. If action is taken to reduce garbage and plastic production, it’s possible to make a difference. Continue reading Tsunami Talk Took Place This Week in Prince Rupert – CFTK Prince Rupert
