World Tsunami Awareness Day Quiz

The purpose of World Tsunami Awareness Day is to promote tsunami awareness and preparedness, ensuring that people living in coastal areas are better informed about potential risks and how to respond in case of a tsunami.

Tsunamis are primarily caused by underwater earthquakes. When tectonic plates shift and release energy, it creates powerful seismic waves that can propagate across the ocean and result in a tsunami.

If you are near the coast and feel strong shaking from an earthquake, you should evacuate immediately to higher ground. Tsunamis can arrive within minutes and it's important to move to safety as quickly as possible.

The Pacific Ocean is most prone to tsunamis due to the presence of tectonic plate boundaries, particularly in the Ring of Fire, which makes it a seismically active region.

Staying in low-lying areas is not a recommended action during a tsunami warning. The safe course of action is to move inland and to higher ground, as advised by local authorities, and follow evacuation orders to ensure personal safety.

The Intergovernmental Oceanographic Commission (IOC) leads the international coordination of tsunami warning systems. It provides a platform for countries to collaborate in sharing tsunami-related data, information, and best practices.

Seismic sensors are used to detect and monitor tsunamis. These sensors are capable of measuring and recording seismic waves that result from earthquakes, providing crucial data for accurate tsunami warnings.

World Tsunami Awareness Day is observed on November 5th, which marks the anniversary of the devastating Indian Ocean tsunami that occurred on December 26, 2004.

The formation of a mushroom cloud is not a sign that a tsunami is approaching. Receding ocean water, unusual rise or fall of tides, and strong shaking or earthquake can be warning signs of an incoming tsunami.

Indonesia was the most affected country by the 2004 Indian Ocean tsunami, with Aceh province experiencing the highest number of casualties and widespread destruction.

The approximate speed of a tsunami in open ocean is 500-600 miles per hour (800-970 kilometers per hour). Despite this high speed, tsunamis can still travel across entire ocean basins, allowing sufficient time for coastal regions to prepare and evacuate.

The term 'tsunami' means 'harbor wave' in Japanese. This term accurately describes the characteristic behavior of a tsunami, where the height of the waves increases significantly near coastal areas and in harbors.

Developing community evacuation plans is a recommended practice for tsunami preparedness. These plans involve identifying safe evacuation routes, establishing designated meeting points, and educating community members about the necessary steps to take in case of a tsunami warning.

If you are caught in a tsunami while swimming in the ocean, the appropriate action is to dive underwater and remain submerged until the waves pass. Trying to swim towards the shore or staying afloat can expose you to greater danger and risk of injury.

Emergency broadcast systems play a crucial role in disseminating tsunami alerts to the public. These systems utilize various channels such as radio, television, and mobile devices to inform coastal communities about the imminent danger and necessary actions to take.
