[最後はグループごとにプレゼン！]
[A final presentation by each group]
|
All 5 groups did their presentation on their favourite topics. Here are topics and some important points that each group introduced.
Group A: Topic[Volcanos]
1: Pre-Fuji volcanoes; Mt. Fuji consists 4 volcanoes.
2: Volcanic history of Shin Fuji; The volcanic activity of Mt. Fuji can be divided into five different stages. Activity decreased from A.D.1000.
3: Crater locations and the tectonic settings of Mt. Fuji; The craters of Mt. Fuji follow the line of subduction.
4: Macroscopic Geomorphology; The Hoei Eruption dykes.
5: Culture; Goraiko, the sunrise seen from the peak of Mt. Fuji.
6: Evacuation plans; Evacuation plans are showed for the event of future Mt. Fuji eruption.
7: Microscopic Geomorphology; Lava Tree Molds and the womb Mold.
Group B: Topic [Tsunami in Japan]
1: Generation of the tsunami; Energy released by the earthquake inside the oceanic plate generates the Tsunami.
2: Evidences from the past; Can be seen from the past tsunamis deposits in Sanriku region. Also from the historical literature such as the Nihon Sandai Jitsuroku.
3: Tsunami features; Tsunami has some interesting features, such as its relationship between the velocity, depth, and the height. When the tsunami is travelling around deep ocean, velocity is very fast, but the height is short. When the Tsunami is travelling around shallow ocean, the velocity is slower, but the height is a lot taller.
4: Coastal Features and Mitigation Strategies; Since the topography of coastlines affects the force of tsunami, it is important to have mitigation plans that are suitable for each locality.
5: Technologies and Engineering; After the great Tsunami event, engineers tried hard to reconstruct the sights that are damaged by the Tsunami.
Group C: Topic [Volcano]
1: Geomorphology of Mt. Fuji; Structure of the mountain is unique since it contains different volcanos from the past.
2: Volcanic Histories; Indicating the Hoei eruption was the most recent eruption. Existence of 3 different craters at Hoei eruption site indicate that Hoei eruption was not a single eruption, but was 3 different eruptions.
3: Evacuation plans; Evacuation plans are made and updated regularly to enhance the awareness that Mt. Fuji will erupt in future.
4: Culture: Warship and Art; For example, a poem of Mt. Fuji from “Manyoshu”, which is the oldest collection poetry. Another example of painting of Mt. Fuji from “Thirty-six views of mount Fuji”.
5: Modelling; The use of geophysical flow model, ash distribution models, and tephra dispersal models help to construct the Hazard map for Mt. Fuji future eruption.
Group D: Topic [Tsunami]
1: What is Tsunami; There are several types of Tsunami categorised by how it is generated such as landslide generated, and earthquake generated.
2: The Tohoku region and 3.11; Explained by one of the members from Group D who was living in Tohoku region during the 3.11 earthquake. She told us what she experienced during the earthquake.
3: The outside perspective of 3.11; Explained by showing how the media reacted to the event.
4: What technology exists to mitigate the effects of a Tsunami; Japan Meteorological Agency has an equipment to monitor all the small earthquakes occurring at Japan, which can detect the micro earthquake before the big earthquake occur. This is used as a warning system in Japan.
5: What can be done to prepare for the future Tsunami; By analysing the Nankai trough activities, past Tsunami deposits, and constructing Inochi-yama mountain, and Tsunami evacuation tower, we are able to mitigate some impacts of the Tsunami in the future.
Group E: Topic [Mt. Fuji]
1: Cultural history; Religion at Mt. Fuji is based on Shinto which is one of the Japanese original religion.
2: Volcanic History; There were two main eruption, Jogan and Hoei eruption.
3: Geomorphology; Group E showed the lava flow history of Mt. Fuji and the magma contained at Mt. Fuji is explosive basaltic magma. Also, they showed that Ropy Pahoehoe Tree Molds are observable at Mt Fuji.
4: Evacuation plan; Since the eruption can be explosive, a hazard map is created for Mt. Fuji future eruption.
5: Miscellaneous; Building construction; Group E explained how to construct a building in a country with such intensive earthquakes. Understanding the geography, right use of material and design provide a well quake resisting building.
Even though some groups presented similar topics in their presentations, but they were still very inspiring for everyone.

[AORIにある寿司屋「はま」にてさよならパーティー]
[Farewell Party at Hama the Sushi restaurant in AORI]
|
After all the presentations were done, we had a farewell party at Hama the Sushi restaurant. After spending two weeks in Japan, students from ANU said that they have seen and learnt so much that they would never experience back in Australia. Even though it was very sad to say goodbyes, we knew that we will see each other again in near future. Of course, the trip was not only inspiring to the students from ANU, but also to the U Tokyo students as well. We all learnt about the geological hazards not only by the lectures but also by seeing and feeling through visiting many different sights.
