A 50-centimeter tsunami hit an island south of Tokyo, Japan, on Tuesday following a magnitude 5.8 earthquake in the area, Japan's weather agency said.The focus of the quake was located in waters near Torishima Island in the Izu island chain in the Pacific. The tsunami was detected at Hachijo Island, while a 20-cm tsunami and a 10-cm tsunami were also recorded on Kozu Island and Miyake Island, respectively, according to the Japan Meteorological Agency (JMA).The agency issued a tsunami advisory for the Izu and Ogasawara islands shortly after the temblor but lifted it then, determining that the activity had sufficiently subsided. The quake initially registered M5.9 but was later revised down, Kyodo News Agency reported.No damage has been reported, according to Tokyo police.Japan is located at the meeting point of 4 tectonic plates, making it particularly vulnerable to seismic activity. The country is also home to 100 active volcanoes.A 9-magnitude earthquake in 2011 and a tsunami killed more than 15 thousand people and caused a disaster at the Fukushima nuclear plan
