A woman is reading the latest Tsunami Watch News 2025 indoors in a printed newspaper.

Is a tsunami really going to come?
What does Tsunami “Watch” mean?
Is this just an alert or something else?
We’ll explain what a tsunami watch is and what’s going on in the world right now in plain English in this comprehensive post.
π What is Tsunami Watch?
Tsunami Watch means that after a big earthquake, there can be a risk of a tsunami in the ocean, but it is not yet confirmed whether the wave is really happening or not.
This is just a precautionary alert which warns people to be prepared.
π Understand the difference:
Tsunami Watch = time for preparation and alertness
Go to high ground right away if there is a tsunami warning.
π Why did the Tsunami Watch Alert come?
On 3 July 2025, a 7.9 magnitude earthquake struck the ocean near Japan. This earthquake was so powerful that it shook the ground beneath the ocean.
Immediately after this, the Pacific Tsunami Warning Center issued a Tsunami Watch:
Affected areas included:
Japan
Indonesia
Hawaii (USA)
Alaska
Philippines
US West Coast (California etc.)
π How does the Tsunami Monitoring System work?
Seafloor pressure sensors
GPS buoys (which measure ocean waves)
Satellite signals
Earthquake sensors (seismographs)
As soon as a major earthquake occurs, all these systems are activated and track any unusual activity in the ocean waves.
If something dangerous is detected, a watch is issued first, and if necessary, a warning is issued.
π‘οΈ What should be done when a Tsunami Watch comes?
These are some important rules that should be taken during tsunami watch:

β Do this:
Prepare the way to the high ground beforehand
Keep emergency bag ready (water, mobile charger, medicine, torch, documents)
Keep fuel in the car
Keep your family safe
β Don’t do this:
Don’t go near the sea
Don’t spread rumours
Don’t share anything on social media without confirmation
Don’t panic, just stay prepared
π§ Lesson from the past
Indonesia of 2004 Tsunami:
The 9.1 magnitude earthquake and tsunami killed two lakh people. At that time the alert system was weak.
2011 Japan Tsunami:
There was an alert system here, but people ignored it thinking it was just a watch. Result: more than 15,000 people died.
That is why taking a tsunami watch lightly is not right in any situation.
π’ Need for awareness among the public
Often people do not understand the difference between “watch” and “warning”. When a tsunami watch is issued, people either panic or ignore it.
It is the responsibility of both the media and the government to give people timely and correct information.
πΊοΈ Tsunami Planning is the responsibility of every person
People in every coastal area should know about tsunami related things:
Make an evacuation plan
Prepare a list of safe zones
Hold drills in schools and offices
Create a map system or QR code that is simple to understand.
π¬ Understand with a simple example:
Imagine, you see on TV that the weather around you is bad, and it might rain β do you run away immediately?
No, you prepare by grabbing an umbrella.
The same is true for tsunami watches:
Be prepared, don’t panic.
π¨ What if a warning is issued?
If it changes from “Watch” to “Warning”, then immediately:
Go to high ground
Drive the car if the roads are open, otherwise run away
Steer clear of heading toward the water. Await the return of the authorities’ signal.
π Last thing:
Tsunami Watch is only an “advance alert”. It gives the news that there can be danger. In such a case:
Always stay updated
Keep your safety first
Keep the danger away with caution
Life is only available once a week. It is the responsibility of all of us to protect ourselves from natural hazards like tsunamis.

Tsunami Watch 2025 β FAQ
Q1: What was the cause of the recent tsunami watch?
The second earthquake occurred on July 29, 2025, and its magnitude of 8.8 struck off the Kamchatka Peninsula in Russia and caused a powerful tremor to occur, sending tsunami warnings to many parts of the Pacific.
What areas were put on tsunami warnings?
There were tsunami warnings or advisories in Russia, Japan, Alaska, Hawaii, and the West Coast of the U.S.
Japan made threats and evacuation notices along its coasts in the Pacific. Alaska and some of Hawaii were also put on the alert of possible waves hitting.
Q3: What was the expected or observed height of the waves?
It had been predicted that there would be surf waves of 3β4 meters in certain areas of Kamchatka and the surrounding Kuril Islands. Japan had a high of 1.3 meters waves at certain coastal areas.
Alaska and Hawaiian coasts were also getting ready to face lesser and still harmful waves and currents.
Q4: Did it have any casualties or damages?
Reported losses and massive casualties have not been confirmed so far. A single death took place in Japan during evacuation; a car drove off a cliff, as its driver was attempting to flee in a different place.
Far East Russia experienced some coastal flooding, heavy currents and property damage in Far East Russia, particularly in Severo-Kurilsk.
Does it have any current threats and warnings?
Majority of the tsunami warnings and advisories were canceled by the end of July 2025. Nevertheless, coastlines are monitored in case of aftershocks or unusual changes in sea level. Researchers emphasize the fact that tsunamis usually come in series with time.
