Japan issues tsunami warning after magnitude 7.3 earthquake
- temp 10y ago10km depth http://typhoon.yahoo.co.jp/weather/jp/earthquake/20161122055958.html http://typhoon.yahoo.co.jp/weather/jp/earthquake/20161122055...
- b_emery 10y agoApparently not a threat to Hawaii - Tsunami threat for Japan: http://ptwc.weather.gov/text.php?id=hawaii.TIBHWX.2016.11.21.2109 http://ptwc.weather.gov/text.php?id=hawaii.TIBHWX.2016.11.21... "THE PACIFIC TSUNAMI WARNING CENTER HAS ISSUED A TSUNAMI THREAT MESSAGE FOR OTHER PARTS OF THE PACIFIC LOCATED CLOSER TO THE EARTHQUAKE. HOWEVER... BASED ON ALL AVAILABLE DATA THERE IS NO TSUNAMI THREAT TO HAWAII."
- rubiquity 10y agoIf I read your link correctly, that announcement is saying the earthquake is not a threat to Hawaii.
- Freestyler_3 10y agoIt also says that there are warnings for places closer to the earthquake. (ie Japan)
- dsp1234 10y agoNot sure why the downvotes on this one. It's probably good news for the people in Hawaii, and for those of us who have friends/family there, that there is no threat.
- civilian 10y agoUSGS map: http://earthquake.usgs.gov/earthquakes/eventpage/us10007b88#map http://earthquake.usgs.gov/earthquakes/eventpage/us10007b88#... //edit Any idea when the tsunami will hit? The original news happened at 20:59 UTC (1pm PST), but I'm not sure how fast tsunamis travel. A sister comment referenced tsunami.gov, which is for US dwellers, but this NOAA website has more information for people living outside the US: http://ptwc.weather.gov/?region=1&id=pacific.TSUPAC.2016.11.21.2129 http://ptwc.weather.gov/?region=1&id=pacific.TSUPAC.2016.11.... text: http://ptwc.weather.gov/text.php?id=pacific.TSUPAC.2016.11.21.2129 http://ptwc.weather.gov/text.php?id=pacific.TSUPAC.2016.11.2... ESTIMATED TIMES OF ARRIVAL -------------------------- * ESTIMATED TIMES OF ARRIVAL -ETA- OF THE INITIAL TSUNAMI WAVE FOR PLACES WITHIN THREATENED REGIONS ARE GIVEN BELOW. ACTUAL ARRIVAL TIMES MAY DIFFER AND THE INITIAL WAVE MAY NOT BE THE LARGEST. A TSUNAMI IS A SERIES OF WAVES AND THE TIME BETWEEN WAVES CAN BE FIVE MINUTES TO ONE HOUR. LOCATION REGION COORDINATES ETA(UTC) ------------------------------------------------------------ KATSUURA JAPAN 35.1N 140.3E 2150 11/21 KUSHIRO JAPAN 42.9N 144.3E 2217 11/21 HACHINOHE JAPAN 40.5N 141.5E 2236 11/21 SHIMIZU JAPAN 32.8N 133.0E 2312 11/21 NOBEOKA JAPAN 32.5N 131.8E 2319 11/21 So, Katsuura was just hit, and the other cities will be hit soon.
- huangc10 10y ago(Edit) Japan Meteorological Agency has updated the earthquake to 7.4 magnitude.
- hccampos 10y agoLive stream: http://www3.nhk.or.jp/nhkworld/en/live/ http://www3.nhk.or.jp/nhkworld/en/live/
- johansch 10y agoI have been watching this (through their great Apple TV fourth gen app) for the past hour. They have been excellent at doing live-translations of the primary NHK domestic broadcast. About 45 minutes ago the tone of the japanese language speaker in the background was really, really emotional, loud and fast. Reports of tsunami sightings at various distances from the seaside, factory fires etc were coming in by the minute. They are warning people of returning to the seaside too early; now warning of a possible ~90 cm tsunami that might still be very strong. Edit: Prime minister Abe made a brief, live speech to the nation.. and the NHK put him in a small picture-in-picture box in the lower left part of the screen so that they could still show the live view of the seaside. That was special.
- agildehaus 10y agoThey're reporting a 3 meter tsunami is expected in Fukushima.
- komali2 10y agoJapan has been mastering the art of picture-in-picture boxes for the last 30 years of television.
- huxley 10y agoWas that Abe, I thought it was one of his cabinet ministers?
- johansch 10y agoOops, may have been. I wasn't paying full attention to the TV at the time, just heard the english translator say "something something prime minister Abe something live statement something something" and then saw a small box with a Japanese man of approximately the right age speaking.
- cossatot 10y agoAccroding to the USGS's page (linked to by civilian), the earthquake was a strike-slip earthquake, where two blocks of crust slide laterally relative to eachother on a vertical fault, with no real uplift of subsidence of the seafloor. It's unlikely that there will be a major tsunami, as these are caused by rapid displacement of lots of water by the seafloor. However, given the right topography along the fault, it is possible.
- dforrestwilson1 10y agoInteresting thanks for the details!
- honkhonkpants 10y agoAuthorities are warning of at most 1m above high tide levels. http://ptwc.weather.gov/ptwc/text.php?id=pacific.TSUPAC.2016.11.21.2129 http://ptwc.weather.gov/ptwc/text.php?id=pacific.TSUPAC.2016...
- flukus 10y ago1.4m has been recorded so far.
- huangc10 10y agoFor reference, the tsunami from the Tohoku earthquake from 2011 (which caused the Fukushima disaster) was as high as 40m.
- samwilliams 10y agoI was going to ask for a source for that 40m figure, but I just found it. That is absolutely terrifying. Edit: To put in context, even if your were at the top of a ten story building, the wave (and ensuing mass of water) would still reach you.
- rconti 10y agoAnd if you were at the top of an eleven story building, you'd find yourself without 10 stories to support you!
- rdlecler1 10y agoI was in Tokyo at my hotel when it happened. I thought maybe I had a Japanese vibrating bed for an alarm clock before realizing what was happening. I was on the 7th floor of a hotel and there was a slight sway for about 45 seconds. Given the duration I assumed it was fairly sizeabke but far away.
- kazinator 10y agoJapanese vibrating bed? Motels in America have had those since the 60's. https://en.wikipedia.org/wiki/John_Houghtaling https://en.wikipedia.org/wiki/John_Houghtaling John Joseph Houghtaling (pronounced HUFF-tay-ling;[1] November 14, 1916 – June 17, 2009[1]) was an American entrepreneur and inventor who in 1958 invented the Magic Fingers Vibrating Bed, a common feature in mid-priced hotels and motels from the 1960s to the early 1980s. (Well, maybe they are Japanese, now, haha). The Japanese invented massage chairs some years before this, though, and a vibrating bed might be regarded as a derivative thereof: Robotic massage chairs were first brought to market in 1954 by the Family Fujiryoki company. https://en.wikipedia.org/wiki/Massage_chair https://en.wikipedia.org/wiki/Massage_chair Anyway, cheers to lucky you to be in Japan, even if shaken up!
- flukus 10y agoIt's funny how our attitudes change depending on the location. In Japan a vibrating bed is seen as technological sophistication, in America it's old and tacky.
- oolongCat 10y agoEverytime something important happens I notice reddit is a better source of getting an aggregate of information than twitter or (sometimes) news outlets. Relevant reddit thread for this incident. https://www.reddit.com/r/worldnews/comments/5e6jzt/73_magnitude_earthquake_hits_fukushima_japan_3/ https://www.reddit.com/r/worldnews/comments/5e6jzt/73_magnit... Also, /u/TheEarthquakeGuy should be posting soon.
- huangc10 10y agoAgreed. I would say this is actually a feature of Reddit that the team there has worked on over the years.
- rangibaby 10y agoExcept for that time they framed someone completely innocent for the Boston bombing. We did it Reddit!
- manachar 10y agoGood for news and raw info - REALLY bad at analysis.
- toomanybeersies 10y agoI found that for the New Zealand earthquakes last week, that Twitter was a better source than Reddit for information that was actually relevant to me as a local.
- komali2 10y agoThe livestream is talking about how 2 methods of water cooling at the Fukushima power plant, but there's no immediate danger because of some third system. Anybody have more details on this? "Right now the water temperature is 27 degrees and the water temperature will not rise to dangerous levels... for a while."
- dandelany 10y agoWorryingly, TEPCO is reporting that the cooling system for the 3rd reactor at Fukushima Daiichi has stopped (via the NHK live TV stream)... Supposedly there is enough water in the pool that it will not be dangerous for quite awhile, but this needs to get fixed soon.
- johansch 10y agoA week, they just said, I think. That seems manageable. The cooling system stopped operating because of the odd water movements, but wasn't reported to be damaged. "TEPCO expects the cooling system to operate normally in 1-2 hours from now."
- criley2 10y agoOut of curiosity... why is this on Hacker News?
- tempestn 10y agoSame reason as always. Because it is news, and of interest to many people who visit this site.
- Practicality 10y agohttps://news.ycombinator.com/newsguidelines.html https://news.ycombinator.com/newsguidelines.html This fits "Anything that good hackers would find interesting." "anything that gratifies one's intellectual curiosity." Major world events are pretty much always on topic. We just don't need minor regular news events here.
- mbesto 10y ago> "Anything that good hackers would find interesting." "anything that gratifies one's intellectual curiosity." So that can literally be anything... > If they'd cover it on TV news, it's probably off-topic. This caveats it nicely. This is certainly off-topic for HN.
- mynameisvlad 10y ago> probably off-topic Probably !== certainly. The only people who can really speak to something being certainly off-topic are the moderators.
- flukus 10y agoJavascript or PHP?
- mynameisvlad 10y agoHeh, didn't even realize it, but JS (well, Typescript.)
- euske 10y agoTsunami alerts/forecasts: http://typhoon.yahoo.co.jp/weather/jp/tsunami/ http://typhoon.yahoo.co.jp/weather/jp/tsunami/ They should really provide an English version of this page. Come on, Yahoo Japan.
- enzanki_ars 10y agohttp://www.jma.go.jp/en/tsunami/ http://www.jma.go.jp/en/tsunami/ The Japanese Meteorological Agency provides a greater source of info.
- reddytowns 10y agoI have a Japanese friend who said whenever a quake in NZ hits, the whole of Japan is on edge for the next month because Japan quakes often follow NZ quakes after a couple of weeks. It seems to have happened again. I wonder why you don't hear anything in scientific circles about this.
- sdrothrock 10y agoIt might be that the scientific circles have more data (that is, those of us in Japan only really notice the big ones and the local ones) that show that there isn't really a correlation at all due to the frequency of quakes in both areas.
- ekianjo 10y agoWas there this morning the shake was pretty long, several minutes. Its rare.
- euske 10y agoThis is a good opportunity so I'm gonna post what I, a native-born Japanese, have been always thinking: This country is literally shaped by earthquakes. This is true not only in a geological sense but it also applies to the culture. Earthquakes affect how all the buildings here are made, the way of transportation, and virtually every aspect of our daily life. We always fear them and talk about them, but we're kinda resigned to accept the fate. This concept of resignation is seen in many ways in the Japanese culture. But it's also earthquakes that make us truly united. I realized this when the big quake hit the country five years ago. As much as we hate them, we are defined by earthquakes.

- chdkcncnd 10y agoLiterally.
- marban 10y agoI remember reading that the majority of Japanese rather accepts the consequences of earthquakes than giving up natural hot springs in exchange.
- 6t6t6t6 10y agoAs someone living in Tokyo, I can only say: Too bad that earthquakes and tsunamis do not define the way how nuclear power plants are built, though....
- mark_edward 10y agoThey did. But resistance is not infinite. It was a really bad earthquake and tsunami combo.
- 6t6t6t6 10y agoA big tsunami like that happens about once every 500 years. It the life of the nuclear plant is 50 years, the risk of a disaster happening was 1/10. I don't think that this was an acceptable risk. Even a risk of 1/100 or 1/1000 would be unacceptable. That means that the nuclear plant should have never been there, or should have been prepared to be run over by a tsunami...
- SeoxyS 10y agoI was woken up by the quake this morning. Pretty strong feeling; it shook for a good few minutes. As far as I can tell everyone's safe in Tokyo, though the trains are a bit delayed and the elevators in my building weren't running. Stronger by far than any quake I've ever felt in 8 years in San Francisco.
- yitchelle 10y agoReading the news article, it says that the waves are about 1m in height, some are about 60cm in height. How do they distinguish that these waves are caused by the earthquake and not waves created by other causes (ocean currents, wind etc)?
