First, I need to write an original article about "Expose Sur Les Tsunamis". The context provided includes snippets about tsunamis from various sources, but I must use this information naturally without directly copying. The article should be 600 to 900 words, with natural headings, and avoid unsupported claims. I should not mention that it was AI-generated. The keyword is "Expose Sur Les Tsunamis", which is French for "Report on Tsunamis". So, the article should be in French. I'll write in French to match the keyword. From the context: - "Want to know everything about tsunamis? In this ProjetÉcolo video, we explain what tsunamis ARE and how they form." - "Comment fonctionnent les" (How do they work) - "Les" (The) - "L'immense vague d'un" (The immense wave of a) - "C'est quoi un" (What is a) - "Retrouvez encore plus de vidéos 'C Jamy' sur france.tv" (Find even more videos 'C Jamy' on france.tv) - "Imagine a massive wall of water crashing into New York City..." - "Abonnez-vous, c'est pour la science !" (Subscribe, it's for science!) These snippets hint at topics like what tsunamis are, how they form, their causes, effects, and examples. I'll structure the article around these points. Outline for the article: 1. Introduction: Define tsunami and grab attention. 2. What is a tsunami? Explain the concept. 3. How do tsunamis form? Discuss causes (earthquakes, etc.). 4. The characteristics of tsunamis: Wave behavior, speed, etc. 5. Historical examples: Mention some major tsunamis. 6. Impacts and warning systems. 7. Conclusion: Summary and call to action. Ensure natural headings: Use h2 and h3 tags. For example, "Qu'est-ce qu'un tsunami ?", "Comment se forment les tsunamis ?", etc. Avoid unsupported claims: Stick to scientific facts. Don't speculate. Length: 600 to 900 words. I'll aim for around 750 words. Write in French. Use HTML tags: h2, h3, p, ul, ol, li, strong, em. No markdown fences. Start writing. First paragraph: Introduction. Use the keyword naturally. "Expose Sur Les Tsunamis" should be the theme, but I don't have to repeat it verbatim in the text. The title isn't required, but I'll incorporate it. I'll begin with: "Les tsunamis font partie des phénomènes naturels les plus impressionnants et dévastateurs. Mais que savons-nous vraiment d'eux ? Dans cet exposé sur les tsunamis, nous allons découvrir leur fonctionnement, leur formation et leur impact." Then, move to "Qu'est-ce qu'un tsunami ?". Explain that it's a series of ocean waves caused by large disturbances. Next, "Comment se forment les tsunamis ?". Discuss earthquakes, volcanic eruptions, landslides, etc. Use the context: "L'immense vague d'un tsunami peut atteindre des hauteurs impressionnantes..." etc. Incorporate phrases like "C'est quoi un tsunami?" naturally in the text. For historical examples, mention events like the 2004 Indian Ocean tsunami or 2011 Japan tsunami. Impacts: destruction, loss of life, environmental effects. Warning systems: how they work, importance of education. Conclusion: Emphasize understanding and preparedness. Now, write the HTML structure. I'll use: - h2 for main headings. - h3 for subheadings if needed. - p for paragraphs. - ul or ol for lists. Example:

Qu'est-ce qu'un tsunami ?

Un tsunami est une série de vagues océaniques provoquées par le déplacement soudain d'un grand volume d'eau...

Ensure it's safe HTML: only specified tags. Check word count: I'll write and then count. Let me draft the content. --- **Article:**
