Researchers from Cardiff University have been busy investigating whether or not underwater sound waves might be helpful in assisting with tsunami warnings.
Researchers say that the AGWs, which are naturally occurring sound waves, travel much faster than the tsunami itself, about 10x faster, and that they can be detected by only a single underwater hydrophone.
Scientists say that from this data, that they would be able to determine information such as:
- the duration of a potential tsunami
- the location
- orientation
- speed
- dimensions
And with every second of extra warning time that people can get, the better chance that there is to try and save lives.
Right now, the warning systems for tsunamis around the world consist of using floating devices that are known as dart buoys (see image above).
These devices are used to measure pressure changes in the ocean. This method also requires a hefty distribution, with many buoys being scattered around the world. And researchers admit that they often aren't able to provide much of an advance warning, as well they're also costly to maintain.
Aside from possibly increasing the warning time, researchers have also previously looked at the possibility of using artifically-generated AGWs to possibly stop a tsunami from potentially reaching land, or if anything mitigate its effects.
Ideally, they suspect that they might be able to fire AGWs at an incoming tsunami in the hopes that it would in-return disrupt the waveforms and eventually reduce the impact and potential destruction. However, researchers say that at this point it's just an idea, we are still quite some time away from seeing this demonstrated in real-time.
Eventually, scientists behind the work say that they want to develop a method for tsunami warnings that could be set off within minutes of the hydrophone station picking-up the sound signals.

I also wonder why they have not done this before useing underwater sound waves it totally makes sense to me ! thanks for sharing @doitvoluntarily ! upped and resteemed !😀👍✌💕
I hope they will find a way to identify the tsunami asap!!! thanks for sharing @doitvoluntarily!
Tsunami and other natural disasters are scary. This summer my village suffered during the flood. The shower went a few days and all the rivers overflowed. fortunately, there were no casualties among the population. Hurt some animals and property of the people. And even such a small (compared to the tsunami) natural anomaly caused wild fear in my village. The people were panic-stricken. And the authorities and management were absolutely not ready for actions in an emergency situation. No one expected such a. Therefore, I am even afraid to imagine what is happening during the great natural disasters. Well, if scientists really help to anticipate such events in advance. So that people could prepare for the disaster, to save their lives and property. I hope one day humanity will be able not only to predict a catastrophe, but also to learn how to prevent it.
Good job of the researchers. Thanks for sharing this.
a very useful post
These are excellent news, these researchers can really help to save many lives not only at the UK but all around the world. Glad to read this post.
Waaw is very useful for everyone, I am in aceh Indonesia has never felt the tsunami in the year 2005 ago ,, hopefully they do not feel the same thing we have ever felt ,,, success selau ,, post useful @doitvoluntarily
Good post
With our country within the Pacific Ring of Fire, this would be very helpful. Early detection, more lives and properties saved. Thank you.
"they might be able to fire AGWs at an incoming tsunami in the hopes that it would in-return disrupt the waveforms and eventually reduce the impact"
That would be one hell of an underwater sound system.
To be perfectly honest, I'm surprised this is a new thing. Considering how much acoustic waves are used in marine life already.
Not that I'm much of an expert. Maybe I'm really ignorant. I don't know, ha!
The impact of the tsunami was enormous, not just the collapsed physical building but the human psyche. As happened on December 24, 2014 in Aceh-Indonesia. You've never seen it before
Many many thanks to Cardiff University for the Researchers of investigating whether or not underwater sound waves, obviously it might be helpful in assisting with tsunami warnings. All the Best @doitvoluntarily
I do not know much the mitigate of tsunami disaster, In Aceh province has become tsunami, now Just ready to far of sea area when the hightly earthqueke become
I would like to translate your post if you allowed to Indonesia, to spread This information for our people community :)
Greeting from Aceh sumatra Indonesia
Hi @doitvoluntarily ! Sorry but Steemit chat is now down , never mind about my previous request for a guest judge , I longer need one . Thanks ! 👍✌💕😀
Very useful technology
bookmarked!!, I like your web steemit blog!
If they could slow or decrease the tsunami that would be amazing. Great post 💯🐒
our history in aceh at the time of the tsunami has lost thousands of lives because there is no tsunami warning buoy after the tsunami warning altogether have been installed either still active or already damaged we do not know yet. in the development of Tsunami Instrument Analysts is more important. thank you scientists who have built the tsunami buoy.
