Some volcanoes often sleep for hundreds of years, and some even sleep for tens of thousands of years.
The time when a volcano wakes up is only a short period of sleep.
If it weren't for the "once-in-a-thousand-year" volcanic eruption in Tonga in June 5438 +20221October, maybe the volcano is just a noun to us.
The volcanic eruption triggered a severe tsunami, which not only affected the countries around the Pacific Ocean. Tonga was interrupted by volcanic eruption and the whole territory fell.
How do we tell children about volcanoes? Apart from its unpredictable terror, what influence does the volcano have on our lives?
Then this book "Volcano Sleeping, Volcano Awakening" is definitely a treasure picture book, telling parents and children about the popular science knowledge of volcanoes in a story way.
After 5 years and 38 arguments, it is a light science picture book that combines beauty and rigor.
From modern times to ancient times, tell us the true volcano story.
The author Yasuhara was born in Chiba Prefecture and graduated from Musashino Fine Arts Short-term University.
This book is edited by Yukio Hayakawa, Ph.D. in Geology at the University of Tokyo. Two professionals work together to introduce the perspectives of geology and history. Through exquisite painting style and rigorous revision, readers can feel the activities of nature from the life scenes, expressions or reactions on people's faces at that time.
Open the front cover and the back cover at the same time. Two little girls, with their backs to us hand in hand, stood on a lawn blown by the wind and waved to the volcano in the distance.
The story begins with the title page. On a sunny day, the teacher took the children up the hillside and looked at the volcano in the distance. With maps and notes in their hands, the children listened to the teacher talk about the process of volcanic eruption, and observed and recorded it.
The picture is spread out in a large space, highlighting the majesty of nature and the sense of power of volcanic eruption.
Volcano is a landscape formed by volcanic eruption, which is composed of lava and pyroclastic rocks. Usually, the shape of a volcano is conical, which is mainly composed of a volcanic cone, a crater and a spout.
The prototype of this volcano in the book is Mashan, which spans Nagano Prefecture and Gunma Prefecture in Japan, with an altitude of 2,568 meters. It is one of the few active volcanoes in the world and one of the famous mountains in Japan 100.
Mashan has erupted several times in history. This book introduces four volcanic eruptions in the past 25,000 years. Even the same volcano will have different eruptions in different periods.
In the Showa era, the volcano woke up in the latest eruption. A southerly wind blew the volcanic ash to the north, and people living near the volcano seemed to be used to it. The next day, climbers will run to the volcano, stick paper on the still hot rocks and drink a cup of hot tea.
More than 200 years ago, in the Edo era, this volcano woke up one day in midsummer, and people were killed by smoke and stones all over the sky. Everyone was so scared that they fled the town in a hurry.
During the peacetime 900 years ago, the volcano also woke up. Huge mushroom clouds rose into the sky and volcanic ash spewed out. Before people could react, they were ruthlessly swallowed up by the pyroclastic flow.
25,000 years ago, it was much colder then than it is now. There are still a few people living at the foot of the mountain. With the awakening of the volcano, people can obviously feel the strong earthquake. The collapsed volcano not only swallowed the foot of the mountain, but also annihilated a large area.
Four outbreaks, each of which has an impact on human environment. However, with the progress of human beings and their understanding of volcanoes, human beings are becoming more and more calm in the face of volcanic eruptions.
Volcanic eruption is terrible, and it will also trigger a series of natural disasters such as earthquakes and tsunamis. However, it will also bring some benefits. For example, sulfur after volcanic eruption is a good mineral; Volcanic eruption can make the originally barren land fertile; Volcanic eruption can also preserve a complete city, which will be a good monument hundreds of years later; Volcanic eruption will form rain.
At the end of the picture book, there are professional explanations and Asayama eruption chronology, which will help us to deepen our understanding of volcanoes.
Human beings are so small in front of nature, cherish life, respect nature and fear nature.
