Radiation levels spiked up with M4.6 in 3 municipalities of Fukushima
Following up this article.. M4.6 hit Hamadori Fukushima / Seismic intensity 4 [URL]
From NRA (Nuclear Regulation Authority)’s real time monitoring data (Graphs attached below), radiation levels spiked up when the earthquake occurred.
The area is Southern part of Fukushima prefecture. 3 municipalities experienced the rapid increase of the atmospheric dose up to 54%.
The increase started around 16:30 and had the peak when M4.6 occurred. It went back to the normal level around 19:00.
Observing the spikes in 3 municipalities in the same area of Fukushima, it can be difficult to judge it was merely a malfunction of the monitoring posts.
There is a possibility that small quakes have been occurring before M4.6 hit and those lead to the increase in the radiation level.
However Tepco hasn’t announced any abnormality about the plant status.
