Potential tsunami threat to the CNMI: Community urged to stay vigilant

Editor’s note: The CNMI Office of Homeland Security and Emergency Management said, “To be clear on the press release, there is no tsunami threat for the CNMI as of right now. We want to make sure that the community practices preparedness measures in case of a potential tsunami threat in the future. Due to the recent activities in Japan, we want the CNMI to be in a state of heightened awareness of the possibility of a potential tsunami.”

The CNMI Office of Homeland Security and Emergency Management is a tsunami-ready agency, partnered with the National Weather Service to ensure proper communications redundancies for receiving and pushing our earthquake and potential tsunami threat information to the community.

The large 7.1-magnitude earthquake in Southwest Japan on Aug. 8, 2024, is a reminder that the CNMI is in a seismically active region of the globe with earthquake, and potential tsunami sources up and down the Northern Mariana Islands chain and across the Asia Pacific region.

A potential tsunami threat is possible but is not guaranteed. Therefore, the CNMI should be in a state of heightened awareness of the possibility of a potential tsunami.

What is a Tsunami?

A tsunami is a series of large ocean waves typically caused by underwater earthquakes, volcanic eruptions, or landslides. These waves can travel at high speeds across the ocean, causing significant damage and loss of life when they reach shorelines.

It is crucial to understand the risks and take appropriate steps to protect yourself and your loved ones.

Recognize the warning signs

1. Natural Warning Signs:

• Strong Earthquake: If you are near the coast and feel a strong or prolonged earthquake, it could trigger a tsunami. Act immediately.

• Sudden Sea Level Changes: If the ocean suddenly recedes or rises dramatically, this is a clear sign that a tsunami could be imminent.

• Unusual Ocean Behavior: Rapidly rising or falling water, strange noises from the ocean, or a loud roaring sound could all indicate a tsunami is on its way.

2. Official warnings:

• Tsunami warnings will be issued through official channels such as local news, radio stations, and emergency alerts. Pay attention to these warnings and follow any evacuation orders immediately.

Tsunami preparedness tips

1. Know your risk:

• Determine if you live, work, or visit areas at risk of tsunamis. Coastal areas and regions near the ocean are most vulnerable.

2. Create an emergency plan:

• Identify safe evacuation routes to higher ground or inland areas. Practice these routes regularly with your family. • Establish a communication plan with your family members, including a designated meeting place if separated. 3. Build an emergency kit:

• Prepare an emergency kit with essential supplies that can last at least 72 hours. Include items such as water, non-perishable food, a first aid kit, medications, flashlights, batteries, important documents, and a battery-powered radio.

4. Stay informed:

• Keep up to date with weather reports, earthquake activity, and tsunami warnings in your area. Sign up for emergency alerts and follow local authorities on social media.

5. Practice Drills:

• Regularly participate in or conduct tsunami drills to ensure everyone knows what to do and where to go in the event of a tsunami.

During a tsunami

1. If you feel an earthquake:

• Drop, cover, and hold on until the shaking stops. Once it is safe, immediately move to higher ground or inland, avoiding coastal areas.

2. Evacuate immediately:

• Do not wait for official warnings if you observe natural warning signs. Move quickly to a safe location away from the coast.

3. Stay away from the shore:

• Do not return to the coast until authorities have declared it safe. Tsunamis often come in multiple waves, and the danger may last for hours.

4. Follow official instructions:

• Listen to local authorities and emergency services. Follow their instructions on when it is safe to return to your home or coastal areas.

After a tsunami

1. Return safely: Only return to your home when authorities say it is safe. Be cautious of debris, damaged infrastructure, and potential hazards such as downed power lines or contaminated water.

2. Provide assistance:

• Check on neighbors, especially the elderly and those with special needs. Offer help where possible and report any injuries or significant damage to emergency services.

3. Stay informed:

• Continue to monitor official channels for updates and information on any ongoing risks or recovery efforts. Stay Alert and Stay Safe The safety and well-being of our community are our top priorities. By taking proactive measures now, we can mitigate the risks and ensure the safety of our families and the community.
