On tuesday I felt two earthquakes while I stayed in the office. Both were situated in the same region, a little north east of Tokyo out in the sea. The first one was at 5.4 in strength, the next one was at 6.0 in strength. No tsunami warnings were sent out and the Fukushima reactors were reported to still be stable. The strength was of course a lot lower in Tokyo than in the epicenter, but it was still noticeable. I first realise that it was an earthquake by feeling a bit dissy, a little bit seasick, maybe like being on a boat. This is only due to the quite slow swaying of the building we work in when an earthquake of low frequency. The last one of the two earthquakes was a bit bigger than what we normally have, but not big enough that it was any scary. At least I got a video from it! You can only see a very small shaking of the plant we have in the office.
Even though this was not a big earthquake, it´s good to know that they take EHS seriously at the office and are prepared for bigger earthquakes in the future. Elkem Japan has actually moved office after the 9.0 earthquake in March to a safer building now. We all have a helmet (to put on if there is a big earthquake) underneath our desk. In addition there are blankets, water and some food stored in case of a bigger emergency. And as you may have read there is a 70 % risk of a big earthquake (over 7.0 in strength) hitting Tokyo within 4 years. Then it´s good to be prepared and on the safe side!
