Esse Vulcão JÁ APAGOU O JAPÃO uma Vez. KIKAI Está Recarregando!

In March 2026, researchers from Kobe University and JAMSTEC confirmed that the magma chamber of the Kikai Caldera, on the seabed south of Japan, is recharging with new magma—injected from an even deeper source, just 2.5 to 6 km from the ocean surface. --- 📍 TikTok:   / xandoes   📍 Instagram:   / xdlabstudio   --- 🌋 WHAT IS THE KIKAI CALDEIRA? The Kikai Caldera is a supervolcano located mostly on the ocean floor, south of Kyushu Island, Japan, within the Kagoshima Graben—a rift in the seabed that extends into the East China Sea. It is part of the Pacific Ring of Fire, the region responsible for about 90% of all earthquakes on the planet. --- ⏱ CHAPTERS ✅ 0:00 The Toba Supervolcano and the Near Extinction of Humanity ✅ 1:51 Why a Submarine Volcano is More Dangerous ✅ 2:59 What is the Kikai Caldera and Where is it Located? ✅ 3:27 The Kikai-Akahoya Eruption: The Largest of the Holocene ✅ 5:18 What the March 2026 Discovery Revealed ✅ 6:26 How Japan Monitors the Caldera Today ✅ 7:16 What Would Happen in a New Eruption ✅ 9:25 Supervolcanoes in the World: Yellowstone, Toba, and Others ✅ 10:12 Will This Happen Again? --- 📊 QUICK FACTS ABOUT THE KIKAI CALDEIRA Location: Ocean floor, southern Kyushu, Japan — Kagoshima Graben Caldera diameter: Approximately 19 to 20 km Last major eruption: 7,300 years ago (Kikai-Akahoya eruption) Akahoya eruption classification: VEI 7 — largest eruption of the Holocene Pyroclastic flow reach: Up to 100 km across the ocean Volcanic ash reach: As far as Hokkaido, 1,700 km away Study: Nagaya et al., Communications Earth & Environment, March 2026 — Kobe University / JAMSTEC Current alert level: Level 2 (scale of 5) — Japan Meteorological Agency Recent eruptions: September 2024, December 2025, May 2026 (small) Estimated chance of a major eruption in the next 100 years: 1% Comparison: same power category as the Tambora supervolcano (1815) --- ❓ FREQUENTLY ASKED QUESTIONS ABOUT THE KIKAI CALDEIRA Q: What is the Kikai Caldera? A: It is a submarine supervolcano located south of Japan, in the Kagoshima Graben, part of the Pacific Ring of Fire. Its last major eruption, 7,300 years ago, was the largest of the Holocene. Q: Why is the Kikai Caldera more dangerous than other supervolcanoes? A: Because it is on the ocean floor. While land-based supervolcanoes, such as Toba and Yellowstone, mainly generate volcanic winters, Kikai would combine tsunamis, pyroclastic flows, and ash cover in the atmosphere in a single event. Q: What did scientists discover in 2026? Q: Researchers from Kobe University and JAMSTEC have identified that the magma chamber from the 7,300-year-old eruption is being replenished with new magma—injected from an even deeper chamber—and lies only 2.5 to 6 km deep beneath the ocean floor. Q: Does Japan monitor the Kikai Caldera? A: Yes. The Japan Meteorological Agency maintains the region at Alert Level 2, on a scale of 5. Small eruptions were recorded in September 2024, December 2025, and May 2026. Q: What is the chance of the Kikai Caldera erupting? A: Studies estimate approximately a 1% chance of a large-scale eruption in the next 100 years. There is no way to accurately predict when or if it will happen—but the size of the potential impact justifies constant monitoring. Q: What would happen if the Kikai Caldera erupted today? A: The sequence would be: a large magnitude earthquake, followed by a tsunami hitting the entire coast of Asia, Central America, and North America. Then, pyroclastic flows sweeping up to 100 km around. Finally, ash in the atmosphere generating a volcanic winter with a global impact on temperature and agriculture. Q: What is the difference between the Kikai Caldera and the Toba supervolcano? A: Toba is on land, on the island of Sumatra. Kikai is on the seabed and, therefore, a new eruption would also generate tsunamis—making the scenario potentially more destructive in terms of immediate impact. --- 🔎 TOPICS OF THIS VIDEO Kikai Caldera Japanese supervolcano Submarine volcano Kikai-Akahoya eruption Largest eruption of the Holocene Underwater supervolcano Kagoshima Graben Pacific Ring of Fire Volcanic winter Volcanic tsunami Pyroclastic flows Kobe University JAMSTEC study Toba supervolcano Yellowstone supervolcano Kyushu volcano, Japan Global volcanic threat --- 💬 Would you live in southern Japan, a three-hour boat ride from an awakening underwater supervolcano?
