When Will Mount Fuji Erupt? | The True Meaning of 1991 in the Prophetic Manga "The Future I Saw"

Summary

This video delves into the geological features of Mount Fuji, its eruptions, and the complex relationship between earthquakes and volcanic activity. The video highlights Mount Fuji's unique structure, the challenges of predicting eruptions, and historical eruptions linked to seismic events like the 1707 Hoei Earthquake and the 2011 Great East Japan Earthquake. It also touches on ancient texts such as the *Sarashina Diary* and explores the possibility of future eruptions, including prophetic dreams. Emphasizing preparedness, the video urges viewers in nearby regions to stay informed using hazard maps in light of potential volcanic risks.

Takeaways

• 😀 Mount Fuji's height is influenced by pressure from multiple tectonic plates, including the Eurasian, North American, Philippine Sea, and Pacific Plates.
• 😀 The structure of Mount Fuji is unique, with older volcanoes hidden within, contributing to its greater height.
• 😀 Predicting volcanic eruptions at Mount Fuji based on past volcanic activity in nearby regions (like the Izu-Ogasawara Arc) is scientifically uncertain.
• 😀 Studies have explored a potential relationship between volcanic eruptions and major earthquakes, but clear statistical evidence remains limited.
• 😀 The 1707 Hoei Earthquake was followed by Mount Fuji's eruption, but recent events (like the 2011 Tohoku earthquake) did not trigger an eruption at Mount Fuji.
• 😀 Understanding the mechanisms behind earthquakes triggering volcanic eruptions is complex and still a subject of research, with no clear predictions possible.
• 😀 Mount Fuji has been a significant cultural symbol, with references to it in ancient texts like the Tale of the Bamboo Cutter and the Sarashina Diary.
• 😀 The Tale of the Bamboo Cutter suggests Mount Fuji emitted smoke in ancient times, which is supported by historical records of eruptions in the 10th century.
• 😀 Mount Fuji has erupted 10 times since the 8th century, and its current state is relatively peaceful with little volcanic activity.
• 😀 Predicting volcanic eruptions, like those at Mount Fuji, is difficult, and even prophetic dreams, such as those in the manga 'The Future I Saw,' are speculative.
• 😀 If Mount Fuji erupts, it could significantly affect eastern Japan, especially Tokyo, with potential volcanic ash and lava flow, leading to disruptions in daily life.

Q & A

What tectonic plates influence the height of Mount Fuji?

Mount Fuji's height is influenced by pressure from several tectonic plates, including the Eurasian Plate, North American Plate, Philippine Sea Plate, and the Pacific Plate.

Why is Mount Fuji's structure considered unique?

Mount Fuji's structure is unique because it consists of several old volcanoes hidden within it, which have contributed to its increased height through multiple eruptions over time.

What was the relationship between Mount Fuji's eruptions and seismic activity from 1983 to 1989?

From 1983 to 1989, there were several volcanic eruptions around the Izu Peninsula, but there isn't enough data to establish a definitive link between these eruptions and a potential eruption of Mount Fuji.

How do earthquakes and volcanic eruptions potentially trigger each other?

There is speculation that major earthquakes could trigger volcanic eruptions, as seen in historical events like the 1707 Hoei Earthquake, which occurred 49 days before Mount Fuji erupted, and the 2011 Great East Japan Earthquake, which led to increased seismic activity around Mount Fuji.

Why is it difficult to establish a clear correlation between earthquakes and volcanic eruptions?

Establishing a clear correlation is challenging because there aren't enough data points for analysis, and the timing between earthquakes and eruptions can vary greatly, making it hard to define a 'triggering' event.

What was the focus of the 2021 research from Tohoku University regarding earthquakes and volcanic eruptions?

The 2021 research from Tohoku University explored the mechanisms by which major earthquakes might trigger volcanic eruptions, but it emphasized that understanding the mechanism does not allow for accurate predictions of volcanic eruptions after earthquakes.

How did ancient texts, like *The Tale of the Bamboo Cutter*, depict Mount Fuji's volcanic activity?

Ancient texts such as *The Tale of the Bamboo Cutter* suggest Mount Fuji was known for emitting smoke, and it was believed to be the site of significant volcanic activity. This is consistent with evidence that Mount Fuji erupted in the 10th century.

What does the *Sarashina Diary* reveal about Mount Fuji's activity?

The *Sarashina Diary*, written in the 11th century, describes seeing smoke coming from the summit of Mount Fuji, indicating that the mountain was active and potentially erupting during that time.

How has Mount Fuji's activity changed from the past to the present?

In contrast to its frequent eruptions in the past, today's Mount Fuji is much more peaceful, with occasional minor smoking but no large-scale eruptions or volcanic activity.

What are the implications of the prophetic manga 'The Future I Saw' regarding Mount Fuji's eruption?

The prophetic manga 'The Future I Saw' suggests a major natural disaster, possibly an eruption of Mount Fuji, might occur in July 2025. However, this prediction is speculative, and the accuracy of such prophecies remains uncertain.

What is the significance of the 2023 Mount Fuji hazard map?

The 2023 Mount Fuji hazard map is significant as it reflects the government's concern about the possibility of an eruption. It aims to prepare residents for potential volcanic hazards and emphasizes the importance of evacuation plans.
