Understanding the 2011 Japan Earthquake and Tsunami

The video explores the devastating 2011 earthquake and tsunami in Japan, detailing the scientific analysis of the disaster, the mechanics of the tsunami, and the subsequent nuclear crisis at Fukushima. It highlights the immediate response, ongoing challenges, and future risks, emphasizing the importance of preparedness and scientific understanding in mitigating such disasters.

What was one of the immediate effects of the earthquake on Japan's geography?

• Japan moved closer to China.

• Japan shifted three meters out to sea.

• Japan's mountains increased in height.

• Japan's coastline expanded.

What geological feature is responsible for the earthquake in Japan?

• Tectonic plate movements

• Volcanic eruptions

• Meteor impacts

• Ocean currents

How did Japan's early warning systems respond to the earthquake?

• They failed to detect the earthquake.

• They were activated after the tsunami hit.

• They provided immediate warnings across the country.

• They only alerted the coastal areas.

What was a significant challenge faced by the Fukushima nuclear power plant after the earthquake?

• Its cooling systems were compromised by the tsunami.

• It was destroyed by the earthquake.

• It had no backup power systems.

• It was located far from the sea.

Why did the tsunami have varying impacts on different parts of Japan's coastline?

• Differences in local weather conditions

• Varying depths of the seabed and coastal geography

• The presence of sea walls

• Different times of day

What was one of the reasons the tsunami breached the sea walls in Miyako?

• The walls were not completed in time.

• The walls were poorly constructed.

• The earthquake caused the coastline to subside.

• The tsunami was unusually slow.

What was the global response to the tsunami as it spread across the Pacific Ocean?

• The tsunami was not detected outside Japan.

• Only Japan issued warnings.

• Countries ignored the warnings.

• Evacuations were ordered in several countries.

What is a major concern for future earthquakes in Japan?

• The potential for a large quake near Tokyo

• The lack of earthquake data

• The absence of warning systems

• The depletion of tectonic activity

How did the tsunami warning system in Hawaii contribute during the disaster?

• It failed to issue any warnings.

• It was activated after the tsunami hit Japan.

• It provided accurate predictions and warnings.

• It only warned the United States.

What is a key lesson from the 2011 Japan earthquake and tsunami?

• Earthquakes are predictable and controllable.

• Natural disasters can be completely prevented.

• Preparedness and early warning systems can save lives.

• Tsunamis are not a threat to developed countries.
