Japan gets bigger as new coastline emerges

/ 06:00 PM April 27, 2015

TOKYO — Crowded Japan has got a little bit roomier after a 300-meter (1,000-foot) strip of land emerged from the sea and attached itself to the coast, experts said Monday.

The extra stretch of coastline at the town of Rausu on Hokkaido island has risen as high as 10 meters from the sea surface in some places, exposing what used to be the ocean floor to the elements.

Initially the phenomenon, in a remote part of the island, prompted speculation among residents of mysterious seismic activities, fuelling fears of another big quake in a nation scarred by the 9.0-magnitude earthquake and tsunami of March 2011.

But geologists believe the emergence was probably a result of a landslide nearby, when melting ice and snow caused a section of land to drop, pivoting the underwater area into the air.

“An aerial survey indicates that the land swell happened as a result of a landslide,” local researcher Yoshinori Yajima told the Hokkaido Shimbun newspaper after he flew over the area Monday.

Authorities have not been able to determine exactly when the landslide hit the snow-covered coastline, but they do not expect it to expand further, said an official at the central government’s Hokkaido Regional Development Bureau.

“Our understanding is that this is different from earthquakes,” he told AFP.

Rausu is not the only place where Japan is expanding: a new island emerged from the sea 1,000 kilometers (620 miles) south of Tokyo and continues to grow as the volcano at its center spews magma.

In February it was reported to be a respectable 2.46 square kilometers (0.95 square miles) — roughly the size of 345 football pitches.
