The theme of this lecture was the 14th and 18th Earthquake and Volcano Children's Summer Schools.
The 14th Earthquake Volcano Children's Summer School was held from August 3rd to 4th, 2013 in Shimoda City, Shizuoka Prefecture (the tip of the Izu Peninsula), entitled "The Story of the Earth from the South". The chief lecturer was Professor Masato Koyama of Shizuoka University, and the event was held with the full cooperation of the Izu Peninsula Geopark. We traveled around the Izu Peninsula by bus, conducted experiments at the experimental venue, and while discussing with experts, there were presentations by the children, "What did you learn?" And "What did you think?"
Among them, Hayashi is in charge of the experiment. The Izu Peninsula was a submarine volcano in the past, but it has risen in the process of collision with Honshu, and the submarine volcano has appeared on the surface of the earth. In order for children to understand this difficult concept, it is necessary to convince them that hyaloclastite and the like erupted on the seafloor. Hyaloclastite is called "crispy lava" at summer school, and "crispy lava experiment" was conducted to show the place where "crispy" cracks in the experiment. This is an experiment in which the tip of a glass rod is heated with a burner, put into water, and a water-cooled crushing phenomenon occurs. In the interviews with the children, it was found that there were reactions as intended, such as "a square piece was formed" and "a bubble was generated". When I interviewed Mr. M, a 6th grade elementary school student who is very familiar with volcanoes and earth science, he said, "The size of the rock seen on the finished glass and the cliff was different, but since I was watching the experiment, how to make underwater lava. I understand. "
The 18th Earthquake Volcano Children's Summer School was held in Mashiki Town, Kumamoto Prefecture from August 9th to 10th, 2017 under the title of "The Secret of the Earth Found in the Kumamoto Earthquake". Mashiki Town was severely damaged by the Kumamoto Earthquakes on April 14th and 16th, 2016. Approximately 30 people from the 4th grade of elementary school to university students take a bus to observe the town, and at Shioi Shrine in Sugido, Mashiki-cho, they observe the surface fault of the Kumamoto earthquake and pumice at the quarry. Taiyo Yamada, a sixth grader at Tsumori Elementary School, felt the power of the earthquake when he saw the displaced fault. I was surprised to hear that the pyroclastic flow was as fast as the Shinkansen, "he said in an interview with the Kumamoto Nichinichi Shimbun. An experiment was conducted at the Mashiki Town Exchange Information Center and a presentation was held.
At this time, I was also in charge of the experiment, and conducted a pyroclastic flow experiment using bath salts and a spring water experiment using bread with Dr. Hikaru Yokoyama of the Volcanological Society of Japan.
What did you get as an expert in these summer schools?
There were two interesting scenes, so I would like to introduce them in the lecture.
