#Japan #Earthquake: Ground Noise in Yonezawa, Yamagata Prefecture

Yonezawa City is in southern-most part of Yamagata Prefecture, bordering Fukushima Prefecture.

A curious bit of news from Yomiuri Shinbun (in Japanese; 4/26/2011), that Japan Meteorological Agency's Yamagata Branch has been receiving reports of loud ground noise in Yonezawa City since early April.

JMA Yamagata Branch speculates that the noise may be caused by small, shallow earthquakes that have been happening very frequently since March 18 in the adjacent Kitakata City and Kita Shiobara-mura in Fukushima Prefecture, and is telling the Yonezawa residents to remain calm.

There is no marked volcanic activity in the Mount Agatsuma on the south of the city.
