Question about tsunami from Japan hitting Vancouver Island

There was a documentary a while back about a certain First Nations community on Vancouver Island, Sarita, British Columbia, near Port Alberni, that had been the victim of a tsunami that reached it from Japan - in other words, not from the Cascadia earthquake - but I'm not certain of the date; 1790 seems a bit late but that might be it, the Okinawa - Iyejima Islands? - tsunami seems like a better date, but would it have had any strength on the other side of the Pacific? I'll see what I can find out about the Sarita tsunami disaster; must be something online somewhere....Skookum1 (talk) 07:44, 21 February 2008 (UTC)

There was a huge tsunami recorded in 1771 in Ishigaki island. The sources are all in Japanese. 61.245.81.52 (talk) 19:31, 21 July 2010 (UTC)

Plural

How would people feel about changing the plural to "tsunamis" throughout the article (including its title)? Wiktionary lists it as a valid plural, and the lack of a final "s" can be needlessly confusing to English readers. --Doradus (talk) 20:12, 20 May 2008 (UTC)

Forgot to mention, I went ahead and made this change a few weeks ago. --Doradus (talk) 17:58, 27 June 2008 (UTC)

Arabian Sea Tsunami - 1341?

A catastrophic event similar to a Tsunami is mentioned in the history of the territory now known as the south Indian state of Kerala. The event occurred in 1341 leading to the silting and closure of the ancient port of Muziris, opening up a new port in Kochi and displacing vast areas of land and water. Since Kerala is on the cost of the Arabian Sea, a sea which has not apparently reported any other tsunami, the event remains to be satisfactorily explained. 116.68.91.27 (talk) 05:13, 2 December 2009 (UTC)

Could have had a Makran origin, especially if it came from the north as the account describes. Still, however, not much data from that region either. —2602:306:BCA6:8300:D57C:89F6:2F46:88BA (talk) 10:29, 1 December 2015 (UTC)

Turkey

'Historic' of 'Historical'

Many of the tsunamis on this list are 'historic', but some like the 2007 Niigata and any before recorded history can only be called 'historical', like that caused by the Storegga Slide. I think that this article should, therefore, be renamed to List of historical tsunamis. I'm aware that there is a slight difference in usage here between American and British English, so I'm seeking comments before making any formal move proposal. Mikenorton (talk) 13:01, 19 November 2011 (UTC)

The most historic tsunami was in 1976. The Google NGram shows how the word tsumani has replaced tidal wave since the WW2 and the biggest peak is in 1976. [2]87.113.178.233 (talk) 14:13, 15 April 2014 (UTC)

If you change the range from 1970 to 2008, you'll see that the biggest peak is actually in 2005-8 (a reaction to the 2004 Indian Ocean earthquake presumably). The second highest peak is actually in 1977, although it's not clear what that's related to, unless it's the 1976 Moro Gulf earthquake. Mikenorton (talk) 18:18, 15 April 2014 (UTC)

Regarding the first point in this section - it's over 2 years and there have been no responses, so I'm being belatedly bold and moving the page. Mikenorton (talk) 20:38, 15 April 2014 (UTC)

Regarding whether the words "and prehistorical" should be added to the list description:

• According to most dictionaries and spell-checks, "prehistorical" is not a word.
• General usage: "prehistoric" is used in contrast to "historic", which in turn is used for past events of note, which are generally included in written history. In the case of human history, "prehistoric" is often systematically used for events before written history. However, this usage is not consistent across all fields.
• We already changed "historic" to "historical", which is simply used to mean past events, not necessarily those of note or those written down. This distinction is common in fields like geology, where some events may be important, while others may merely have occurred in the past. However, many phenomena occur both before and after the advent of written history, but there is no scientific reason to distinguish between the two.
• There are only two event listed for which there are no historical writings, the Storegga slide and Santorini.

Elriana (talk) 18:23, 11 June 2015 (UTC)

Intuitively, it feels strange that an event can be both prehistoric and historical, but your logic seems sound. Pburka (talk) 20:56, 11 June 2015 (UTC)

The English language is a bit quirky. I think there may also be some subtle difference between American and British usage of these words, but I have yet to figure it out.Elriana (talk) 15:49, 12 June 2015 (UTC)

It has only just occurred to me that there would be nothing wrong in simply renaming this page to List of tsunamis (althought that title is currently a redirect to this page) - would that work? Mikenorton (talk) 18:16, 30 June 2015 (UTC)

Table?

If this list were in table form it could be sorted by date, continent or death toll without creating separate lists for each ordering system. Most lists of earthquakes in wikipedia seem to be in table form. Any opinions? Elriana (talk) 04:23, 7 March 2015 (UTC)

I entirely agree - list articles in prose like this are really hard to navigate. I will eventually do it, if no-one gets there first. Mikenorton (talk) 17:34, 27 June 2015 (UTC)

I'm working on turning this list into a table. The columns I'm thinking of are Date, Location, Main Article, Primary Cause (e.g., earthquake, volcanic eruption, etc), and Description. Is there any reason to separate the different time periods (pre-1001 AD, 1001-1700 AD, etc)? Or should all of the events be in a single table? Many of the more recent events have heights associated with them. So we could add a maximum height column, making a separate table for events after 1900 or 1950. All opinions welcome! Elriana (talk) 22:12, 28 June 2015 (UTC)

I made the lists that were organized by date into tables. I'd still like opinions as to whether the separate time periods should be combined (entirely or in part) into a single table. Elriana (talk) 14:15, 30 June 2015 (UTC)

To do

• The section on Other Historical Tsunamis seems out of place, and most of the entries are entirely unreferenced. I would advocate moving that section to the talk page and adding events from it to the main list as references are found.
• Many of the event descriptions need copy editing for conciseness, grammar, and tone.
• The divisions of the table/list by date seem somewhat arbitrary. Is there a justification for keeping these divisions?
• Highest and Deadliest sections could use a little fleshing out. Perhaps we could list the top 5 in each category?

I'll be working on some of the copy editing when I have time. Elriana (talk) 14:21, 30 June 2015 (UTC)

• Agreed, only add those that are sourced and putting others on the talk page is probably the best solution.
• Agreed
• They are arbitrary, but I think that some subdivision is a good idea, as this aids navigation. Historical earthquakes uses similar subdivisions, although of course there are no prehistoric earthquakes to list and 20th century and 21st century events have there own articles already.
• That seems worth doing - this NOAA list of tsunamis with over 30,000 deaths is a start - the 1737 event was a cyclone and this NOAA list of maximum wave heights would also be a start.

Finally, thanks for doing this, it's a lot easier to look at now. Mikenorton (talk) 19:26, 30 June 2015 (UTC)

References

To Do Update

1) We still seem to be missing a number of events.

2) The descriptions column could still use some judicious editing. In particular, those events with their own articles do not need to be described with quite so many details here. That's why we link to the main articles. If we stick to time, place, cause, size, casualties, and, in a few particular cases, one other reason for historical notability, I think we will have covered the important bits. Events without their own article could have a few more details, but if they get much longer than other entries, that content should be migrated into a separate article.

3)Highest and Deadliest sections still need fleshing out. The NOAA database mentioned above is a great source for this.

2017 Greenland tsunami

Doesn't the one on 2017-06-17 in western Greenland qualify (4 deaths), even though it was not caused by an earthquake, but a landslide?

Alternative organization?

I wonder if you folks busily working on this article would like some criticism, and a suggestion. The main criticism is this: in viewing this article, as soon as I get down to the list(s), what I see is four columns of mostly empty space, and a final column jam-packed with text. This is very unbalanced, both aesthetically, and in the presentation of information; it is wastefully inefficient use of screen space. It also means that (for my typical browser configuration) I can see only three or four entries at a time, which is so "zoomed in" that I loose sight of the overall list.

A more efficient way of organizing immediately occurred to me, and I have taken the liberty of replicating your first list ("Prehistoric") here, with a slight but, I think, very useful modification: moving the over-full descriptions out of the table. These are replaced with a link to the descriptions, which now follow the table as regular text.

Exempli gratia:

Tabular list

Date	Location	Main Article	Primary Cause	Description
≈7000–6000 BCE	Lisbon, Portugal		Unknown	Desc.
≈6225–6170 BCE	Norwegian Sea	Storegga Slide	Landslide	Desc.
≈1600 BCE	Santorini, Greece	Minoan eruption	Volcanic eruption	Desc.

[Big change: descriptive text pulled out of the table, replaced with links. Also some formatting adjustments.]

Descriptions

[Anchors can be visible, as here, or not. Various schemes possible here.]

t001: A series of giant boulders and cobbles have been found 14 m above mean sea level near Guincho Beach.

The Storegga Slides occurred 100 km north-west of the Møre coast in the Norwegian Sea, causing a very large tsunami in the North Atlantic Ocean. This collapse involved an estimated 290 km length of coastal shelf, with a total volume of 3,500 km³ of debris. Based on carbon dating of plant material recovered from sediment deposited by the tsunami, the latest incident occurred around ~6225–6170 BCE. In Scotland, traces of the subsequent tsunami have been recorded, with deposited sediment being discovered in Montrose Basin, the Firth of Forth, up to 80 km inland and 4 metres above current normal tide levels.

The volcanic eruption on Santorini, Greece is assumed to have caused severe damage to cities around it, most notably the Minoan civilization on Crete. A tsunami is assumed to be the factor that caused the most damage.

Discussion

Having all that text in a table makes the table harder to edit. But likewise, the text was hard to handle because of all the citation details. So a second thing I did: I moved the full citations (done with the (cite} templates) into their own section where they are easier to handle. In their place I put in short cites that link to the full citations. I also put the full citations in (mostly) vertical format, so that in edit mode they are easier to read, and thus easier to check for errors.

If you play around with this format I think you will find that the display is easier on the reader – the actual list(s) becomes essentially a sortable index into the text, which could become a review article — and also much easier to edit.

• Pretty creative and elegant. Readability/usability often gets overlooked around here, so it seems like this would be a good change. Dawnseeker2000 23:44, 6 July 2017 (UTC)

Thanks. I'm glad that someone likes it. ~ J. Johnson (JJ) (talk) 00:05, 11 July 2017 (UTC)

• From a usability point of view, it might be more useful to keep the description contained within the table. That way, readers can easily scroll through the list and get a quick overview of the various causes and effects of tsunami's. I do however agree with you that the overloaded descriptions create a cumbersome and outright ugly presentation. I'd suggest two somewhat less radical tweaks: First, by widening the last column, the visual balance of the text is somewhat restored. Secondly, the contents of the "description" field could be reduced to a short description, while the reference to the main article is the real "dig deeper" link. As an example of the first tweak:

Date	Location	Main Article	Primary Cause	Description
479 BCE	Potidaea, Greece	479 BCE Potidaea tsunami		The earliest recorded tsunami in history. During the Persian siege of the sea town Potidaea, Greece, the Greek historian Herodotus reports how the Persian attackers who tried to exploit an unusual retreat of the water were suddenly surprised by "a great flood-tide, higher, as the people of the place say, than any one of the many that had been before". Herodotus attributes the cause of the sudden flood to the wrath of Poseidon.

Onkl (talk) 06:38, 10 August 2017 (UTC)

With refactoring the use of space becomes more efficient, but the description becomes dominant, even overwhelming, while the other elements diminish into mere side dishes of information. You might as well put all the descriptions into regular paragraphs, with the other fields incorporated into the headers. It wouldn't be so bad if, as you suggest, the descriptions could be reduced – to something like 10 words. But it is doubtful that the general run of WP editing would be so disciplined. You might do away with the description if each and every tsunami to be included in the list was notable enough to have its own article. But that seems quite unlikely.

The form I have shown here, of taking these elephantine descriptions out of the table, allows the table to do what tables are good at: presenting a set of data in a compact, regular format that facilitates inter-record comparisons. If you expand your example with another couple of records, and then compare with my example, you might notice how breaking the lines in each field (e.g.: "479 / BCE") makes them harder to read, while the increased vertical separation makes it harder to compare fields between different records. Large sections of text generally do not work well in tables; the form shown is a standard way of handling such a problem. ~ J. Johnson (JJ) (talk) 23:54, 10 August 2017 (UTC)

I prefer the descriptions in the table itself. Having them in a separate linked place is confusing to me. The paragraphs for adjacent events end up in sequence with no information on where one ends and the next starts or which paragraph is about what. At the point at which enough information has been added to make this information less confusing, you've essentially duplicated the existing table. If there was a way to make the descriptions show as a preview of a couple of lines that is expandable into the full paragraph upon clicking, that would be very cool. But I don't think wikipedia supports this in tables at the moment?

One thing I have tried to do over the years is shorten the descriptions. Most are not too long (making each entry 4-6 lines tall on my screen), but some are still much longer. I'll keep poking at shortening when I get time, however the consensus here turns out. Elriana (talk) 21:40, 27 December 2018 (UTC)

Orphaned references in List of historical tsunamis

I check pages listed in Category:Pages with incorrect ref formatting to try to fix reference errors. One of the things I do is look for content for orphaned references in wikilinked articles. I have found content for some of List of historical tsunamis's orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for this article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. AnomieBOT⚡ 05:58, 6 October 2018 (UTC)

Icy Bay, Alaska

What about the tsunami at Icy Bay, Alaska in 2015? https://www.gi.alaska.edu/alaska-science-forum/giant-wave-icy-bay --Spucky123r (talk) 22:23, 2 June 2020 (UTC)

You can add it. Wykx (talk) 21:24, 3 June 2020 (UTC)

Missing Teide, ca. 160.000–220.000 BP

It's lacking a major landslide-causing tsunami in the Atlantic, the massive collapse of Volcano Teide (Tenerife, Canary Islands) dated to around 180.000 years ago. Take a look at the caldera left behind (Las Cañadas del Teide) to get an idea of the scale. I can't find immediate data on Wikipedia regarding volume, magnitude, etc., but a quick search could come up with some estimates. In any case, equally ill-documented tsunamis are present in this table, and I believe this one also deserves a mention. Il Qathar (talk) 14:16, 14 September 2024 (UTC)

What we need is a reliable source that a) describes this event and b) gives evidence that a major tsunami was triggered, either from imaging of the landslide or more likely from tsunami deposits. The S2 impact event on the list seems to be insufficiently cited in this regard, not that there's any reason to think that an impact that size wouldn't cause a tsunami (if there was any depth of water at the impact site), but we still need cited evidence.

Is this good for a start?

That's enough on its own to add an event dated to ~170,000 years ago. There is evidence for two tsunamis in the the same time bracket, one due to an initial collapse, the other due to a collapse following a major explosive eruption, which can be covered by a single entry in the list - nice find!
