The great wave off Kanagawa by Katsushika Hokusai is probably the most famous image in Japanese art. It depicts three boats in heavy seas on the point of encountering the eponymous wave, while Mount Fuji is glimpsed in the distance. The print is today often reproduced as the artistic depiction of a tsunami. Did Hokusai really have a tsunami in mind when he composed this work? We examine that hypothesis together with the alternatives, by discussing the image itself and the circumstances surrounding its composition, and by evaluating the wave in terms of the fluid dynamics of breaking waves and in particular of the species termed plunging breakers, of which The great wave is a member, and conclude that it is more probable that Hokusai intended to depict an exceptionally large storm wave. There is a great deal of scientific interest at present in such abnormally high waves, which are often termed freak or rogue waves.

In the past few years we have unfortunately had several reminders of the ability of a particular type of ocean wave -a tsunami -to devastate coastal areas. The Indian Ocean tsunami of 2004, in particular, was one of the largest natural disasters of past decades in terms of the number of people killed. The name of this phenomenon, tsunami, is possibly the only term that has entered the physics lexicon from Japanese. We use Japanese and Western sources to document historical tsunami in Europe and Japan, the birth of the scientific understanding of tsunami, and how the Japanese term came to be adopted in English.

Katsushika Hokusai's 1829 woodblock print, "Under the Wave off Kanagawa," is the world's most iconic portrait of ocean waves. It has been reproduced, quoted, and repurposed over the last two centuries in a widening circle of representations of the unruly, powerful sea. Today's reimaginings of this storied Japanese image often remark upon the dangerous, damaged state of the contemporary ocean. Such commentaries sometimes refer directly to the 2011 tsunami and to its associated Fukushima nuclear power plant disaster. But adaptations of Hokusai's Wave these days also increasingly point to more general anxieties about catastrophic climate change and to worries about ocean pollution, acidification, and plastification. In such usages, the Wave operates as a synecdoche for, a symbolic capture of, the difficult-to-apprehend vastness of the ever-moving, interconnecting, and possibly threatening sea. 1 Hokusai's image has thus lately been leveraged into commentaries upon the Anthropocene-a provocative, and, so far, unofficial, geological term that postulates that humans (anthropos) have come to have significant deleterious effects on planetary ecosystems, effects that can be identified not only in the stratigraphic record, but also in the body of Earth's ocean. 2 If "Under the Wave at Kanagawa" (also "The Great Wave off Kanagawa" or, simply, "The Great Wave") in its early circulations emblematized the historical relation of Japan to the sea and to the transnational connections the sea afforded, re-imaginings today adapt the image to speak to contemporary human-generated global oceanic crisis. Such reimaginings of the Great Wave do so, significantly, by drawing attention to the materials of which such critical artworks are nowadays frequently made: plastic, trash, and other sea-borne detritus-the flotsam and jetsam of a sea damaged by the deleterious geohistorical practices of (some) humans. Heather Davis and Etienne Turpin in Art in the Anthropocene: Encounters Among Aesthetics, Politics, Environments, and Epistemologies argue that "the Anthropocene is primarily a sensorial phenomenon: the experience of living in an increasingly diminished and toxic world." 3 Contemporary revisions of Hokusai's Wave do indeed operate in the realm of the sensorially unsettling-although, perhaps contrary to Davis and Turpin's argument, they do so precisely by bringing into experience that which might otherwise be far away or beyond everyday apprehension and scale (e.g., islands of swirling ocean trash in the far middle of the Pacific). Such works also, through the garbage they incorporate, call into question the

There are some artworks that are simply part of our lives. We can’t imagine being without them. These artworks fascinate, are seemingly easy to understand. The themes are always whittled down to the essentials — like a logo! “The Wave” is one of them. “Under the Great Wave off Kanagawa” (H-7) from the series Thirty-six Views of Mount Fuji (Fugaku Sanjūrokkei) by Katsushika Hokusai is one of the most famous artworks in the world. It belongs to the whole world; it transcends place and time. We feel no initial need to categorize or explain. Why does Hokusai concentrate on this gigantic wave crashing down, seemingly devouring everything? Is the overpowering force of nature alone the aspects he wishes to convey to us? This is one possibility perhaps for understanding the picture: a sudden, precipitous force of nature, and we — symbolized by the people in the boats — are helplessly exposed to it. It is not only the clarity of the composition, but also our possible involvement, which makes...

When considering science fiction as a vehicle for artists and thought leaders to consider the nature of humanity, no better opportunity exists than to explore how humans react to extreme circumstances. Although much of science fiction is situated in the vast, emptiness of outer space, science fiction scenarios also exist on Earth under catastrophic circumstances. Natural phenomena, in particular, present some of the most extreme catastrophes because these are completely uncontrollable by humans. As examples of many possible events Earths natural systems can throw at the fabric of civilization and test the mettle of the strongest individuals, tsunamis and tidal waves can bring with them overwhelming devastation. As a result, relentless tsunamis and giant tidal waves are frequent catastrophic devices in science fiction. One then ponders to degree to which creators take artistic license when invoking tsunamis as compared to a scientific accurate representation. Upon reviewing a subset of instances of tsunamis in recent science fiction films, it is clear that there is significant separation between giant tidal wave walls of water portrayed in film as compared to the relentless reality of tsunamis filmed by actual survivors and victims on Earth, with both being terrifying events.

Tsunami generation by an earthquake is generally modeled by water surface displacement identical to the vertical deformation of ocean bottom due to faulting. The effect of horizontal deformation is usually neglected. However, when the tsunami source is on a steep slope and the horizontal displacement is large relative to the vertical displacement, the effect becomes significant. We show this for two recent earthquakes which generated much larger tsunamis than expected from seismic waves. In the case of the 1994 June 2 Java, Indonesia, earthquake, the focal mechanism was a very shallow dipping thrust and the source was near a very steep trench slope. In the case of the 1994 Nov. 14 Mindoro, Philippines, earthquake, strike-slip faulting extended from ocean to land perpendicular to the coast line. In both cases, we found that the horizontal motion of slope had an important contribution to the tsunami generation.

Truth to say, for most of the three decades that we’ve been involved, tsunami research has been a fairly sleepy field. There happened the occasional tsunami in Japan or Central America and the odd Pacific warning issued for never-materialized waves [“tsu-NO-mi ” broadcast the next day’s headlines], but not much grabbed people’s attention for long. The past few years however have noticed a change of tide (sorry about that) in tsunami perceptions. Certainly this year’s events in the Indian Ocean forged the change, but the turn began earlier primarily due to massing information about “exotic ” tsunami sources like submarine landslides. With accelerating increases in sonar technologies, scientists began spotting undersea landslides everywhere — in submarine canyons, on continental slopes, adjacent to seamounts, and off the flanks of oceanic volcanoes. Like terrestrial slides, the submarine slides spanned a vast range of volume from <0.01 km 3 to>1000 km 3 [Figures 1, and 2]. With ...

is a small town hidden in a bay on Korčula Island in the Adriatic Sea. In the early morning of 21 June 1978, the sea suddenly began to rise in the town, overtopping the piers and surging into the streets. The rumble of the incoming water awakened inhabitants who witnessed a series of destructive ocean waves, flooding much of the city and causing devastation and widespread damage. Tsunami-like waves with trough-to-crest heights of up to 6 m and periods of about 18 min appeared without any warning, resulting in the greatest natural disaster in the modern history of Vela Luka. Subsequent scientific investigations indicated that the waves were not related to a seismic event or submarine landslide but to atmospheric processes, identifying this as a meteorological tsunami event (Hodžić , 1979/1980; Orlić , 1980). Tsunamis are the main cause of destructive seiches observed in the World Ocean. However, long waves generated by atmospheric forcing (atmospheric gravity waves, pressure jumps, frontal passages, and squalls) can also be responsible for significant, even devastating, long waves which have the same temporal and spatial scales as typical tsunami waves. These waves are similar to ordinary tsunami waves and can affect coasts in a similar way, although their catastrophic effects are normally observed only in a limited number of specific bays and inlets. Nomitsu (1935), Defant (1961) and Rabinovich and Monserrat (1996, 1998) suggested the term 'meteorological tsunamis' ('meteotsunamis') for such waves. At certain places in the World Ocean, hazardous atmospherically-induced waves occur regularly and have specific local names: 'rissaga' in the Balearic Islands, 'marubbio' ('marrobio') in Sicily, 'šćiga' on the Croatian coast of the East Adriatic, 'milghuba' in Malta, 'abiki' and 'yota' in Japan, 'Seebär' in the Baltic Sea, 'death waves' in Western Ireland, and 'inchas' and 'lavadiads' in the Azores and Madeira islands. These waves have also been documented for the Yellow and Aegean seas, the Great Lakes, the northwestern Atlantic, for coastal areas of Argentina and New Zealand, and in some specific ports such as Port Rotterdam (cf.
There is no sea without waves. The openness, the vastity, the amplitude of the immense surface of water is intrinsically associated with the idea of movement, from the little ripples that come ashore in the calm days of the Mediterranean to the gigantic tidal waves of the oceans. Agitated by both internal and external forces, by submarine currents, winds, and, in the Anthropocene, also by human navigation, the sea is perennially striated, as Deleuze would have put it. The liquid essence of the sea makes it the instable counterpart of the terrestrial world, a continuously changing mass of water that, exactly because of this mutability, both fascinates and terrifies. Waves are the visual patterns of the sea. They are a promise of topological order that constantly suggests a rhythm but constantly alters it into a myriad of variations. Waves are, also, the curvilinear result of the encounter between the rectilinear essence of water and the forces that bend it, that move it upwards or downwards, that cause its inflation and deflation, its inflexion and deflection. Waves are, then, an element of conjunction between two worlds, between earth and sea, between land and water, and between water and air. Winds touch the sea, the sea touches the land, and what results is an ungraspable spectacle of particles of water arranged into complex configurations. There lies the charm and the mystery of waves: they break the order of water, yet they also compose the visual order of the sea. They elude any attempt at calculation (thus representing a conundrum even for present-day physics), yet they constantly promise an order, or at least a range of patterns. Waves are also a force in themselves, combining the energies of water and air, of sea and wind, able to destroy but also to create power, that of ancient myths as well as that of modern wave-powerplants. Thus, whenever an instable material is inflected by forces that imprint on it some rhythmic, curvilinear configurations, humans recognize waves, not only in water, but also in air (soundwaves) or in even light, to such a wide extent that a certain quantum physics identifies waves as the primary constituent of the universe. Thus defined, waves are indeed everywhere in nature, in the rhythms and sounds of the human body, in those that are used to compose the voice of language, in the semantic patterns that grow and dwindle in culture, exactly like waves. Yet the most famous waves, the epitomic waves of all, remain those that seem to emerge from nothingness in the middle of an ocean, then run for long distances as delicate white horses, and finally break their crests against the cliffs of the world. The theory of catastrophes seeks to pattern this evolution, yet before modern mathematics traditional cultures too have sought to come to term with waves, denominating them, articulating them into types, naming these types in more or less detailed categorizations depending on how important waves were in the meshes of each culture. Waves are words, but waves are images too, in countless representations, and they are metaphors as well, of a force that mounts and declines, of a sudden burst of energy, of a rhythmic arrival, of everything that is wavy and undulating, that comes and goes, that rocks and breaks, that splashes and washes, that advances and withdraws, in the perennial, liquid oscillation that seems to beat at the heart of nature.

More-than-human cosmologies, as expressed in contemporary art practice, present a plane for sensing and feeling the extent of the ecological strain on our planet. The relationship between geos, biota and Anthropos is untenable; we are divided by forced climate displacements for humans and the rapid mass extinction for a plethora of flora and fauna. From the intensifying tropical cyclones in Te Moana-Nui-A-Kiwa, the Pacific Ocean in 2019–2020, to the swathes of violently destructive wildfires in Australia and California sparked on occasion by dry lightning and fanned by strong winds, we no longer need scientific projections to hear and feel the shattering signs of climate change. Even the bastions of contemporary art can’t escape the convergence of weather gone awry as art objects and more-than-human waters meet. Venice, where I visited the Japanese Pavilion described in this paper, was later swamped by a deluge of lagoon water during the 58th Art Biennale in 2019. To radically shift...

Tsunamis are gravity waves that propagate near the ocean surface. They belong to the same family as common sea waves that we enjoy at the beach; however, tsunamis are distinct in their mode of generation and in their characteristic period, wavelength, and velocity. The type of tsunamis that induce widespread damage number about one or two per decade. Thus ''killer tsunamis'' although fearful, are a relatively rare phenomenon.

The repetitive narrative that, "Tsunami waves and receded coastal water initiated by an earthquake are closely related," is analyzed through the sequential events that followed the earthquake; a mechanism based on the interaction of receded water with magma is suggested to explain the amplification of Tsunami wave deep beneath the ocean floor (Fig.1), where earthquake occurred under the seabed's or in coastline; the mechanism explained how the water is amplified into steam in the magma chamber, as its volume increased 1,700 times, the transformed water encompass the tremendous force that uplifted the ocean water endowed it with such destructive force; the mechanism explained characteristics related to Tsunami wave, including relation with earthquake and volcano, receding costal water, the foams, inundation, runup, the nature of the great force of Tsunami, ideas to calculate the magnitude of Tsunami force and energy, volume of receded water, volume of tsunami wave, the repetition of its wave; these and related issues are stated; the idea is derived based on the continual flow of lava from earth's interior and the existence of magma reservoir bellow earth's surface in places like Yellowstone in USA and hotspot beneath Hawaii, such magma chamber when existed under seabed, if opened by crack during earthquake, can easily lead to an interaction between receded water and the magma, resulted in the suggested mechanism, all is based on logical analyses and deep thinking to attained the Tsunami Mechanism in response to 2004 and 2011 human tragedies; thus understanding this mechanism will help laying measures to counter the phenomenon, which will reflect positively in saving lives and mitigate its destructive force and reduce consequences of its impact on local societies and above all to understand its true mechanism.

Writings on natural disasters reflect tragic experiences of peoples and the nostalgic cravings after it. This study examines the portrayal of earthquakes, storms and tsunamis as a national concern in Japanese literature. The portrayal of the theme, which has remained a topical issue, is psychological, and sociological. The portrait of personal and communal loss is a reflection of the perspectives and survival strategies that emerge after such disasters occur. This study examines two narrative accounts and a poetry piece written to capture the magnitude and effect of the earthquakes at different periods in Japan. The study examines these writings visa -vis media accounts of the recent 2011 Tōhoku earthquake and tsunami, and the Fukushima Daichi nuclear disaster.

Twenty-one papers on the 2011 Tohoku, Japan tsunami are included in Volume I of the PAGEOPH topical issue ''Historical and Recent Catastrophic Tsunamis in the World.'' Two papers discuss seismological aspects of the event with an emphasis on tsunami generation and warning. Five papers report the impacts and effects in Japan through field surveys of tsunami heights, building damage, and tsunami deposits or analysis of satellite data. Eight papers report the tsunami effects on other Pacific coasts, including the Kuril Islands, the USA, French Polynesia, the Galapagos Islands, Australia, and New Zealand. Three papers report on analyses of the instrumental records of the 2011 Tohoku tsunami, and two more papers report their modelling efforts of the tsunami. Several of the above papers also compare the 2011 Tohoku and 2010 Chile tsunamis.

Abstract. An extraordinary “rissaga ” event (the local name for high-amplitude sea level oscillations) with 4–5 m of amplitude occurred on 15 June 2006 at Ciutadella (Menorca, Spain). In this paper we describe the rissaga event and propose that the meteorological mechanism responsible for it was an unusual pressure jump, associated with a convective squall line. 1

The Hokusai woodcut entitled The great wave off Kanagawa has been interpreted as an unusually large storm wave, likely to be classed as a rogue wave, and possibly generated from nonlinear wave dynamics (J. H. E. Cartwright and H. Nakamura, Notes Rec. R. Soc. 63, 119–135 (2009)). In this paper, we present a complementary discussion of this hypothesis, discussing in particular how linear and nonlinear mechanisms can both contribute to the emergence of rogue wave events. By making reference to the Great wave's simultaneous transverse and longitudinal localization, we show that the purely linear mechanism of directional focusing also predicts characteristics consistent with those of the Great wave. In addition, we discuss the properties of a particular rogue wave photographed on the open ocean in sub-Antarctic waters, which shows two-dimensional localization and breaking dynamics remarkably similar to Hokusai's depiction in the woodcut.
