In this presentation, I will introduce "YUREO 2.0," a simplified version of the experimental device for simulating landslides caused by seismic motion, "YUREO.
On January 1, 2024, a large earthquake with a magnitude of 7.6 m on the Richter scale occurred on the Noto Peninsula Japan, causing tremors with an intensity of 6 to 7 on the Japanese seismic scale (JMA seismic intensity database) (Earthquake name: The 2024 Noto Peninsula Earthquake). As a result of this earthquake, seismic tremors and a tsunami caused extensive damage. The Noto Peninsula has many steep slopes, and the seismic tremors caused many landslides. As a result, roads were cut off and local relief efforts were severely hampered.
Japan has many mountainous areas, and landslides often occur during earthquakes. It is of great significance to learn about landslides caused by earthquakes in such a country. Ishida and Fujioka (2005) discuss the development of classes in "Sougouteki Gakushu" at elementary schools to deepen children's correct knowledge and understanding of local natural features and disasters, and to enhance their disaster awareness and ability to take action. Thus, it is important for disaster prevention to address landslide disasters caused by earthquakes in school education.
The " YUREO " is an experimental device for simulating landslides caused by earthquake motion (Suzuki et al. 2009a, Suzuki et al. 2009b, Suzuki et al. 2009c, etc.).
The " YUREO " consists of two plywood boards and nine springs. Nine springs are glued between the two boards, allowing the upper board to vibrate freely. The upper board can vibrate freely. A mountain is made of soil and shaken by hand to generate a landslide or landslide.
The "YUREO" was used in elementary school science classes and its effectiveness was verified (Suzuki et al., 2009c), and in the Mt. Kurikoma Area Geopark, it was used to explain the Aratosawa landslide that occurred during the Iwate-Miyagi Nairiku Earthquake in 2008.
The "YUREO" allows students to generate shaking with their hands and observe landslides and cliff collapses, which helps them to understand landslides caused by earthquakes.
In addition, "YUREO" was designed to be an inexpensive, easy, and impressive experiment to be used in school education.
However, the springs used must be very strong, and some home centers do not sell them.
Therefore, we developed "YUREO 2.0," a simpler version of YUREO. YUREO 2.0" replaces the spring part of "YUREO" with two round rods. These rods are readily available at 100-yen stores and cost 220 yen for two, which is less expensive than the spring.
You will need a sheet of plywood (about 30cm x 45cm), two round sticks (at least 20cm long), flower soil (about 2L; vegetable soil is also possible), a paper cup or tea strainer, a sprayer (mist), calendar paper (or advertising paper; about 8cm x 13cm), gloves, a bucket The following materials were used for the experiment: a cup of paper, a tea strainer, a sprayer, calendar paper (or advertising paper; about 8 cm x 13 cm), a bucket, green powder (chalk powder or soybean flour), water, newspaper (for one day), and a laboratory table.
As described above, "YUREO 2.0" is even cheaper and easier to use than "YUREO". We hope to promote this system to schools and geoparks in the future.
In the poster session, a demonstration of "YUREO 2.0" will be held.
