Study Notes
Earthquake Mechanics and Events
- Plates are converging at a rate of approximately 8 cm/year between China and Indonesia.
- The 2011 Tohoku Earthquake occurred on March 11, 2011, with a magnitude of 9.0 Megathrust.
- This earthquake is the largest recorded in Japan's history, with intense seismic activity noted in Kurihara City, Miyagi Prefecture.
Tsunami and Nuclear Crisis
- A massive tsunami struck 50 minutes after the earthquake, exacerbating the disaster.
- The Fukushima Daiichi Nuclear Power Plant's reactors were vulnerable, suffering damage from flooding.
- The Japanese government declared a nuclear emergency and initially evacuated residents within a 3-kilometer radius, later expanding it to 20 kilometers.
Human and Environmental Impact
- Approximately 200,000 residents were relocated due to radiation concerns.
- Radionuclide contamination led to long-lasting effects, with 18,000 teraBecquerels of radioactive cesium-137 released into the Pacific Ocean.
- Extensive damage to Japan's infrastructure was estimated between $195 billion to $305 billion.
Economic and Social Consequences
- Japan's economy contracted for two quarters, leading to a recession as production, consumer spending, and business revenue declined.
- The disaster severely disrupted industries, particularly car manufacturing and electronics, leading to global supply chain issues.
- Long-term recovery involves addressing mental health needs, with a spike in PTSD, anxiety, and depression among survivors.
Community and Societal Effects
- The earthquake disrupted community cohesion, leading to the scattering of families and loss of social ties.
- Innovative building technologies like Building Roller Foundation were adopted to minimize future seismic damage.
- Significant displacement forced thousands into temporary shelters due to destroyed or uninhabitable homes.
Seismic Intensity Observations
- Buildings experienced varied damage with different intensities recorded, highlighting significant structural impacts at intensity levels VII and VIII.
- Important buildings affected included hotels, universities, and government institutions, particularly in Baguio City and other regions like Dagupan and Agoo.
Historical Context of the 1990 Earthquake
- A previous significant earthquake occurred on July 16, 1990, with a magnitude of 7.8, causing 2,412 casualties.
- The earthquake's posterior effects included liquefaction leading to the collapse of approximately 20 buildings.
