HCMC promotes appropriate responses to earthquakes and tsunami | Ho Chi Minh City

The seismic zoning map of Vietnam reveals that a magnitude 6-6.2 earthquake could occur over the sea, resulting in a minor possibility of a tsunami with a height of about 0.65 m. This means that its wave crest is lower than the ground. In HCMC, the place that can see such tsunami is Can Gio water. Even so, the city must be well prepared.

Regarding seismic incidents, in the southern region of Vietnam, especially in HCMC, current faults are capable of creating an earthquake as strong as 5.5 magnitude and triggering level 7 tremors. For example , the series of M4.5-5.5 earthquakes in 2004, 2005 and 2007 in the South Sea of ​​Vietnam caused some aftershocks which caused some high-rise buildings in the city to vibrate slightly without any obvious damage.

To limit potential damage, HCMC’s 2022 Earthquake and Tsunami Propaganda Plan details appropriate responses. As a result, when a tsunami is spotted, people should immediately leave their ships parked in port and move to a higher place facing the sea. Ships at sea are not allowed to return to shore until the last Tsunami news is not announced.

When an earthquake is detected, the general rule is not to escape from the building as shaking occurs. When experiencing vibrations, people should move to a safe place and hide there until the shaking stops to exit the building. If you are staying inside a high-rise building, it is not advisable to use an elevator during an earthquake, or create congestion on the stairs. When moving during such an incident, people should have a sturdy object to cover their heads. A flashlight, not a candle, should be used in the event of a power outage to prevent a fire.

People on the street when an earthquake occurs should stay away from tall buildings, tall trees and power lines. People in their vehicles should stop on the sidewalk away from poles and power lines, not under bridges.
