A magnitude 6.8 quake shook western coast of Taiwan at around 9:42 am, Monday, April 20. The epicenter was located at 66 km southeast of Su’ao or 77 km east-northeast of Hualian in Taiwan with a depth of only 17 km.
The quake prompted Japan Meteorological Agency to issue a Tsunami Advisory for Miyakojima and Yaeyama of Okinawa Prefecture. Waves could be high as 1 meter were expected in Sakishima islands, southwestern portion of Japan but no warning was issued for main island Okinawa.
Students in Ishigaki moved in to safer grounds after the announcement and small boats seek refuge at the nearest port.
