Earthquake below the greater Tokyo area, Japan – 首都圏、日本下の地震

USGS Near The South Coast Of Honshu, Japan Nov 24 08:59 AM 4.8


Based on an increasing number of visitors joining us from Japan, we believe that an earthquake was felt.
Update : The hypocenter of this earthquake was at an intermediate depth but the epicenter was very close to Tokyo. As the earthquake was so close to Tokyo, the capital had almost no warning  as the P wave arrived almost at the same time than the S wave.
Update 09:31 UTC : JMA Japan reports a Magnitude of (only) M4.9 at a depth of 80 km. Harmless but well felt by the population. The max. intensity was 4 JM. ER considers 5+ as a potentially dangerous level.
Based on the number of people visiting our site from Japan and compared to other events during the last couple of weeks, people were very anxious to see where the epicenter was.
Update 09:39 UTC : This earthquake proves that earthquakes also happen almost below the city itself and that Tokyo citizens will not always be warned of an upcoming wave as the P and S waves are arriving at almost the same moment.
