Precursor to a huge quake.

Showa sensei wand: check

Handheld mic for extra senseidom: check

Silliest mask available: check

I'm actually in awe of the geniuses of the JMA and their supercomputer. But please don't let NHK hold you back in the 1970s.

(Rant over)

Lately, Kagoshima has had a lot of earthquakes. Is it connected to the recent earthquake in Indonesia?

NOT in the "middle of nowhere", for 1. people live on the islands and for 2. earthquakes in the middle of the ocean? See 2004, 2011, for recent examples for what happens.

The reason he is wearing that mask? For lip readers. Not ridiculous.

Several significant-sized quakes in a relatively short period of time. Makes one a bit uneasy.

Renews those old worries about Sakurajima and the greater caldera in southern Kyūshū, not to mention what lies a little further north.

Several significant-sized quakes in a relatively short period of time. Makes one a bit uneasy.

But not ‘fear mongering’ right? I heard only scientists and the left do that.

PS Akuseki Island itself is a stratovolcano.

The TV camera in the helicopter stayed trained on the peak where the clouds were concentrated.

Quake is unrelated to geological activity in Indonesia.

The nature of earthquakes makes them inherently hard to predict. No one earthquake is identical to another, as they vary in depth within the crust, the amount of energy released and how the rock around them responds.

That said: When a large earthquake is in preparation, the area in which that earthquake will occur will experience a sequence of smaller earthquakes prior to the event. This clustering of precursory earthquakes can occur over just a few months or over a period of decades prior to the major earthquake. The larger the coming earthquake is, the larger the precursors will be and the longer the period and larger the area occupied by the precursors. This phenomenon is known as the precursory scale increase.

However a 6.3 is a major earthquake. And. looking at a current earthquake map - seismic events are so often, it would be difficult to determine what & which quakes are precursors.

but no tsunami warning was issued

You need about 7.5 magnitude to get much of a tsunami at all. A 6.1 earthquake has probably never produced a tsunami, though it is large enough to cause a pretty good shake.

Morning, noon and night these earthquakes go on and on and on, once or twice an hour, so it's not surprising that half the population is fleeing on special ferries to Amami and Kagoshima, a day's journey each way.

@Thomas Goodtime Ridiculous thought on your part!

What a ridiculous mask

-4 ( +3 / -7 )

there's been many earthquakes in Japan recently… I wish a major earthquake wouldn’t happen….

0 ( +0 / -0 )

It is not a ridiculous mask because it is announcement to the general public for a safety emergency. Some people are legally deaf and not all TVs provide closed captions

3 ( +4 / -1 )

If the mask fogs up then it is ridiculous!!!

Akuseki isn't a stratovolcano. That's Suwanose. I live here in Toshima.
