Earthquakes and their impact abroad are summarized below.
Occurrence and Damage of Earthquakes
Earthquakes frequently occur abroad and can cause significant damage. Here are some major examples:
Chile Earthquake (1960): The largest recorded earthquake with a magnitude of 9.5 occurred, causing tsunami damage along the Pacific coast. A tsunami over 3 meters high reached the Sanriku coast of Japan, killing more than 140 people.
Sumatra Earthquake (2004): A massive earthquake with a magnitude of 9.0 resulted in over 200,000 deaths in countries along the Indian Ocean.
Haiti Earthquake (2010): A magnitude 7.0 earthquake killed about 310,000 people and left 1.5 million homeless.
Problems Caused by Earthquakes
Earthquakes abroad cause serious problems such as:
Building Collapse and Human Casualties: In developing countries, poor building standards and construction shortcuts often lead to "pancake collapse" during earthquakes, resulting in many deaths.
Infrastructure Destruction: Lifelines such as electricity, water, and communication are cut off, causing major disruptions to the lives of the affected people.
Secondary Disasters: Earthquakes can trigger tsunamis and landslides, which can expand the damage.
Social Chaos: As seen in the Haiti earthquake, government functions can be paralyzed, security can deteriorate, and looting can occur.
Long-term Impact: Earthquakes can have long-lasting effects such as interruptions in education, economic stagnation, and psychological trauma.
Measures and Challenges
To reduce earthquake damage, the following measures are important:
Earthquake-resistant Buildings: Strengthening and enforcing building standards, especially in developing countries, is necessary.
Early Warning Systems: Building systems to quickly respond to distant tsunamis and other threats is crucial.
Promoting Disaster Education: Spreading correct knowledge and response methods for earthquakes and tsunamis is needed.
Strengthening International Cooperation: Building a rapid support system for disaster response is required.
Utilizing Digital Technology: Using digital technology for information sharing and damage assessment, as seen in Taiwan, is effective.
Earthquakes abroad vary in impact depending on the country's socio-economic situation and geographical characteristics. Therefore, it is important to take measures tailored to each country's situation and to work together as an international community to tackle disaster prevention and mitigation.
