Dpreview.com posted an article about the footage of Sony Kumamoto sensor factory right after the disastrous earthquake last year. The footage was published yesterday. Here is the direct link to the footage on YouTube...

The workers brought the factory back to the fully normal operation in three months.

interesting video, thanks for sharing

Remarkable video about the effects of the earthquake.
The building looks pretty damaged, but I assume it was built to withstand earthquakes?
-
Armando and John, thanks for the comments.
John, the building should be built to withstand the earthquake, but the two consecutive quakes (M6.5 on April 14th and M7.3 on 16th) was powerful enough to leave significant damage to the building. The magnitude number was not extremely high, but the building was so close to the seismic source that the Japanese scale of the earthquake reached to the highest value of "7".

Thank you Akira. Very interesting. And only imagine the nightmare to have a "clean room" clean again. And this is only a detail, to speak.
-
Dave, "we" are well aware of that...
Christian, yes, the clean room appears to have lost everything to keep the room "clean".
-
Very dramatic! My condolences...
-
Akira, thank you for posting. This video shows clearly the terrifying force of the earthquakes.

The media often trot this out.
So why is it called the "Ring of Fire"? Because of all the earthquakes and volcanoes there. Why are there so many earthquakes and volcanoes there? Because it's on the Ring of Fire. The whole concept as used by the media is based on circular logic.
There's nothing special about the Ring of Fire compared to other active tectonic zones around the world. It does contain the majority of the planet's subduction zones (https://www.livescience.com/43220-subduction-zone-definition.html) which tend to create conspicuous tectonic activity, in contrast to seafloor spreading zones where the action is three km underwater and gets ignored by everyone except scientists.
Why does the Ring of Fire exist? Because a majority of the earth's surface is moving towards the Pacific Ocean from both east and west, leading to lots of visible tectonic activity around most of the perimeter of the ocean. Mostly this consists of a series of linked subduction zones, but in a few spots like California and New Zealand, the 'ring' is composed of a transform fault (https://en.wikipedia.org/wiki/Transform_fault).
Besides, it's not even a ring. It's shaped like a deformed horseshoe, with a gap of many thousands of miles at the south end. The term itself is a misnomer.

To my knowledge, the term may be not a misnofmer, as Antarctica in the south is also home to several volcanoes, maybe buried under thick ice...
-
László and Anthony, thanks for your sympathy.
Bill, although the term "Ring of Fire" was new to me, its meaning was obvious. The term is not used or common in Japan. The "circum-Pacific orogenic belt" would be more scientific, I guess?
-

Tejpor, the Antarctic volcanoes occupy a limited area and don't connect up the belt, even roughly. Thanks for bringing this up, though, as I just learned that a new volcanic field has been discovered in west Antarctica with some volcanoes buried under the ice. If there are more discoveries, perhaps in time my statement about the lack of continuity of the ring will prove to be rash.

Akira, you are absolutely correct. I guess what bothers me about the "Ring of Fire" concept being trotted out every time there's a seismic or volcano activity in the area is that it's often used as a somewhat sensationalistic term, one that pretends to convey important meaning but really doesn't. I also live in this belt and can expect earthquakes in the future, but I wouldn't breathe any easier just because I moved to a different tectonically active zone that's not part of the feared Ring of Fire. The degree of seismic or volcanic risk asserted to exist at any one location needs to be based on scientific study of that risk, not on mere co-location with a very lengthy tectonically active region where the type and degree of activity and associated danger vary wildly from one location to the next.
That said, my political jurisdiction of California has the second-highest risk of earthquakes and the highest risk of earthquake causalities and damage of any state in the U.S. We also have some volcanic risk, more than most people realize.

I live rather close to the San Andreas Fault and his friends fracture the San Bernardino valley. Yes, I'm now one of the dirt people, the 909. I've looked into people's bedrooms in Glendale, California where a brick wall once was. The corner walls fell but the floor stayed in place. I think that one hit while people may have been asleep. Bricks were all over the sidewalk and in the street. As far as I know there where no fatalities in Glendale that time.
The perimeter of the Pacific is fair game for earthquakes, tsunamis, do we have to worry about volcanoes too [here in California]?
I'll take this earthquake thing as apposed to living in Tornado Alley. I Apologize in advance is case someone objects to the term Tornado Alley.

As someone born in New Zealand, I am quite well aware of the devastation wrought by earthquakes, tsunamis, and volcanoes.
My grand parents lived in Christchurch and an uncle & aunt on NZ's west coast - two very earth quake prone areas.
I feel very sorry for the devastation suffered by the Japanese people and the Californians as a result earthquakes and tsunamis.

Akira, my condolences too! Forces of nature always remind us how insignificant we are at times.
I am no expert on the Ring of Fire but it's fascinating to learn.
Is Iceland on this ring, because when I visited Iceland I had the impression that they are the most endangered when it comes to earthquakes and volcanoes.
-
Bill, I agree. To me, the term "Ring of Fire" is not really scientific but rather an ironical one inspired by a movie or something like that. I don't know how long this term has been used, though, and I don't really appreciate the term.
Dave and Bill, indeed we share the same fear and sorrow in relate to the earthquake...
Hugh, I well remember the severe earthquake in Christchurch just a couple of weeks before the totally devastating one in the northeastern part of Japanese archipelago. Again, we share the same fear and sorrow.
According to the modern study of the earthquakes in the eastern Asia area, the earthquake attacked Japan in 2011 is said to belong to the series of ones that would occur once in every millennium. And the earthquake would occur as a set of the earthquakes that attacks the north-eastern, central and south-western part of the archipelago. We have only had the north-eastern one yet, we stay warned and horrified.
-
Jakov, I appreciate your condolence. Iceland is not on the ring we are talking about. It should belong to the similar one in the Atlantic area.

David, there are well-known volcanic risks in California, but they're generally located fairly distant from the large metropolitan areas. Mt. Shasta and Lassen Peak are the two best-known volcanoes in the state, but there other locations that have been active in recent centuries such as the Mono Craters near Mono Lake.
On the plus side, we have so much spectacular scenery to photograph here precisely because of all the tectonic activity in recent millions of years. The same is true of other tectonically active areas around the rim of the Pacific Ocean such as Japan, Alaska, New Zealand, etc.

My family has been lucky so far. I don't remember which earthquake, the fireplace and house moved about 6-7mm (1/4") apart. The fireplace was intact with no cracks in the chimney so we calked the gap. Many chimneys fell in the neighborhood. A few cars were crushed. No one was on the streets in the wrong place so no deaths from falling bricks. There will often be a few deaths from heart attacks.
Earthquakes like I've experienced in lessor developed countries often result in multiple thousands of deaths from collapsing buildings. Building codes save many lives.
In nearby Cajon Pass I've been on dirt roads and crossed numerous train tracks and the come out in to rock formations I'd seen in western movies made in the '50s. I don't know why I don't have photographs from the adventure. Maybe I didn't take a camera. I usually did.
My impression is that Japan has suffered the worse earthquakes in the last 25 years while California has been fairly quiet.
