Japan - living in tectonically active locations Volcanoes
Japan's tectonic setting
110 active volcanoes
70% of Japan's land mass is mountainous formed by volcanic activity over millions of years
Japan is located where four tectonic plates meet
widespread subduction gives rise to intense volcanic activity
1200 volcanic eruptions in the last 2000 years
reasons why people choose to live in tectonically active locations
Japan has had geothermal power stations since 1960s
although much of these 'hot rock' locations are located in national parks
creates more jobs
minerals associated with volcanic eruptions, such as sulphur are used in a variety of industrial processes such as production of chemicals.
fertile soils for agriculture - Japan uses just 13% of the country's land area but does so intensively
intensive farming supports the dense population of japan
place attachment - people have emotional attachment to places especially if they have family living there, or its where they work, where there born etc.
some people less fortunate economically may not have much choice but to live in tectonically active locations
tourism also creates jobs
population = 125.7 million (2021)
The population density of Japan in 2022 was 327.94 people per Sq Km
impacts people experience as a result of volcanic eruptions -
Mount Ontake - strato-volcanoe situated 200 km West of Tokyo on Japan's largest island Honshu.
dormant for many centuries until a sequence of eruptions between 1979-1980. further eruptions in 1991 and 2007
27 september 2014 Mount Ontake erupted violently.
killed 63 people
large areas surrounding the volcano were affected by ash fall, pyroclastic flows, volcanic bombs and Lahars (links to spec) (environmental impact)
buildings covered in ash
economic, environmental and political impacts on the country
political
prime minister Shinzo Abe, ordered the military to assist with emergency rescue operations
economic
helicopters and more than 500 troops, police officers and firefighters.
Flights at Tokyo’s Haneda airport were delayed as planes changed routes to avoid the peak
ontake 2240 ski resort opened 2 months late as some slopes were within the 4km exclusion zone - people lost their job for a few months
environmental
soil fertile and rich in elements such as copper, iron, cobalt
