If sound reverberates, the Tohoku Earthquake in 2011 extends to the Norwegian fjords. Also on March 11, 2011, Norway experienced waves climbing their coastline, although no damage was reported. People who caught sight of the waves were also surprised of the disturbance. Further studies traced the waves experienced in Norway back to the 9.0-magnitude earthquake in Japan.
The waves that the Scandinavian country experienced were called seiche, which is, according to Merriam-Webster, “an oscillation of the surface of a landlocked body of water (as a lake) that varies in period from a few minutes to several hours.” According to geologist Stein Bondevik, as high as 5 feet (1.5 metres) of waves were measured past 7:00 AM local time following the Great East Japan Earthquake. “Luckily, they happened at low tide,” said Bondevik, who is from Sogn og Fjordane University College in Sogndal, Norway. He is also a tsunami expert and leads the research on the seiche in Norway.
Bondevik described the oscillation looking “like tsunamis,” considering that it might’ve resulted from an underwater landslide. However, reports of the same sighting in other faraway fjords disputed his initial theory. “Later in the evening I realized there must be a connection with the big earthquake in Japan,” Bondevik admitted. Also, only the fjords facing northeast, and toward Japan, manifested having seiche, which were reported in five towns. People who witnessed the seiche also testified that they only saw the waves in shallow-shored beaches, like river deltas.
