That was a long one, noisy too...enough to shake books off packed shelves. Double-checks quake kit.

grab-and-run bag? Where are you going to run to? Better to duck-and-cover and then figure it out.

A decent rattle in central Tokyo.

my biggest in 26+ years here... 

I can remember at least one a lot bigger than that. About 8 years ago.

I was on the train. Now I know why there was a small delay. Tokyo strikes it lucky again.

That was a strange one here in hachioji. A quick jiggle followed by gentle back and forth then another quick jiggle followed by the back and forth.

Checked my daughters to make sure that they were okay, and then checked around the house. Aside from a few broken cups, there wasn't damage.

I've noticed the past couple of weeks though that there's been a few moderately powerful quakes around the Kanto region.. Ibaraki, Nagano and now off of Chiba.

I was on the throne at work. Not somewhere I want to be if there's a 'big one' as you can't exactly make a quick and clean getaway from there.

Totally missed it... only a 2 here anyway, not really noticeable if you're moving about.

The teachers in Kanagawa prefecture are supposed to say "Shake out" when the evacuation drill begins at school. I was wondering, today, how many teachers used the English expression in their classrooms. I remember saying loudly by mistake "Shape up!"

Was on the way out the door with the kid to her bus stop and it felt like 2 completely different earthquakes, like a jumpy one followed by a rolling one. I’m out here in Hachioji and they said it was only a 2 but it felt a lot stronger than that tbh

I must have slept through it here in Nerima.

I remember saying loudly by mistake "Shape up!"

That’s a great expression to shout at kids in many situations including earthquake drills.

KariHaruka - I've noticed the past couple of weeks though that there's been a few moderately powerful quakes around the Kanto region.. Ibaraki, Nagano and now off of Chiba.

Yes, it’s a very similar scenario to the weeks prior to the 2011 mega quake. Sooner or later luck runs out.

I work at a School, and the School principal is the only one who completely missed the shake because he was busy doing something on his smartphone. I wonder what it was :) :)?

So massive numbers of smart phones going off at the same time with disaster alerts?

I got the powerful one last week even though I live in West Japan but nothing on this one.

How do you have your app set up? I have Yurekuru set up to only give me alerts if the earthquake is more than a Lower 5 on the Shindo Scale.

Thanks to the craftsmanship of Japanese construction that it takes more than a huge magnitude reading to topple a building. Kudos to the architects, scientists,builders etc who make our homes and buildings safe against all odds

6 ( +7 / -1 )

Ah, so there are still people living out there in the east of Japan. Stay safe peeps.

More effective than an alarm clock for habitually oversleeping university students.

-1 ( +1 / -2 )

Just a sharp, quick, up-and-down jolt in Nakano.

And another one, 19:22; this time centered close to Ito on Izu Shimoda, Mag 4.1 .

And I went straight back to sleep. That was a pretty tame one imo.

@Bugle Boy

well, I live 100 metres from the Pacific with nothing between but beach, so duck-and-cover wouldn't help much if a tsunami rolled in.....
