High freak waves were not a ‘mini-tsunami’
Video by Michael Rizzo
A series of freak waves, which to the untrained eye looked like a mini-tsunami, had people scampering from their sun beds and rushing for cover in Sliema on Tuesday evening.
Two-storey high waves hit the area of the Sliema pitch at two-minute intervals at about 6 p.m., sweeping away the waterpolo club’s outdoor furniture. The phenomenon lasted for about two hours and was reported in Buġibba, Xemxija, Golden Bay and Marsascala.
“These freak waves are normally caused by atmospheric pressure. It’s similar to having a hammer pounding on the surface of the sea. The closer the waves get to land the bigger they become,” said Aldo Drago, Professor at the International Ocean Institute at the University of Malta.
“It may look like a very small tsunami but of course it has nothing to do with it,” he said, explaining that the waves can at times even reach a height of eight metres.
He assuaged fears that this might be caused by global warming and pointed out that these waves – technically known as seiche – are not an uncommon occurrence. “There is certainly no need to be alarmed. This is a very common phenomenon here – so much so that we even have a word for it in Maltese: milgħuba,” he said.
This is not the first time that Sliema in particular has been hit by this wave phenomenon: last year similar waves severely damaged the floating pool’s waterpolo pitch. “This year we secured the pool in a different way, so the damage was not as extensive as last year’s,” said Michael Gatt, President of the Sliema waterpolo club, estimating some €5,000 damages this time round.

The phenomenon comes without warming and is not linked to seismic movements. It cannot even be forecasted by the meteorological office.
“On Tuesday we did record a moderate swell, which means that although it’s not windy, the waves can go up to two metres,” said weather forecaster, John Darmanin.
No irregular situation was recorded and it is impossible to tell if it can happen again: “No one can forecast a freak wave,” said Mr Darmanin.
Some people on timesofmalta.com commented that the waves could be caused by the Virtu Ferries catamaran and pointed out that on Sundays, when the catamaran reaches the breakwater, high waves hit the Sliema front. However a spokesman for Virtu Ferries said that on Tuesday the catamaran was in Pozzallo all day and nowhere near Sliema. “The area is prone to freak waves. Without denying that our vessel could cause some waves, the area is full of big ships and pleasure boats,” said the spokesman.
Despite the freak waves people were back on their sun beds at the Sliema pitch early yesterday morning: even the fear of a “mini-tsunami” can’t scare people enough to stop them enjoying their summer.

A sort of mini Tsunami I witnessed years ago in Ghadira bay,when within20 minutes about 40 metres off the shore from the umbrellas the sea got dry,as if a low tide was on,then after the tide came back in and almost reached the wall beneath the road...

it has nothing to do with the waves but its a BIG shame that sliema ASC charge €4 For anyone just trespassing the area to swim in open sea !

Good but all i have to say is this. Despite what the virtue ferries spokesman claim, no known pleasure boat can generate that type of wave unless the boat in concern is about 300m long.........ehh which is not a pleasure boat at all, I assume,……… its an oil tanker on coarse at full speed, about 3 miles of the coast, in which case the wave will loose it’s power as it moves through the water. But in his defense I have been several times in a small boat with the catamaran moving in the harbor at high speed and non of them ever been that high I can assure you. Last but not least yes an atmospheric difference can cause something like this but I is not due to global warming. Global warming is a myth. The main reason for these atmospheric changes is due to climate change, which earth is going thru naturally

Climate Change at all! I hate it when these 'trying to make everything seem common' experts talk like that

Probably just a hint from God to get all those sunbeds and umbrellas off every square foot of sand so that his people can enjoy the beach!

Let's be constructive about this shall we? I think that since it's given that these sort of waves are granted to be battering the Northeast facing coast year-in year-out, a good way of protecting the coast would be that of creating a man made coral reef. Particularly, the scuttling of decommissioned vessels could help provide a breeding ground for corals. For those of us who are not familiar with this procedure, the scuttling of ships after decommissioning is not a source of pollution but actually helps the marine eco system though in a small manner, since the decaying metal would provide food for corals which at a later time would form a reef of their own from the remains.
This could also be aided by deploying underwater barriers, just out at sea so that they would provide a primary line of defense. Of course the waves would still make it to shore in part but at least the coast would not bear the full brunt of the waves. Other than that, it would be wise to seek ways in which to turn the sea into a powerful source of energy. Rather than stopping at just running away from it, we could harvest its potential and turn it into our no. 1 resource in full effect

Nature may be motherly but she can also be a bit of a bitch. In fact she is that all the time. So forget the 'mother' bit. She is an ogress who eats her own children. More prosaically, 'the sins of the mother' (but usually expressed 'in the name of the father and his sins visited upon his sons') is a truism if ever there was one.
Don't go near the water, says the mother to the child. You'll come back home without your flip-flops. Where's Johnny?! OMG, where's Johnny? Where's me? Aaaaaaaargh!!!!*
Mess with Nature and she'll mess with you. For Nature, like Britannia, rules the waves.
And on a more positive note - I remember as a child looked out on the roof of the family home in Hamrun for misbehaving - what was mum thinking? - seeing the sea-spray rise above two miles of roofs looking towards the capital. It was might exciting. The sea was having a bad-hair day. I told you, don't go near the water! Off you go to the roof, banished for half an hour. Until lunch. Because mothers may be punitive but they have a soft under-belly. Until the next punishment.
*Not at all funny, of course. So why say it? I was only trying to make a point, strongly. Honest!
@Kenneth Galea (19th July 11:04). Kenneth, Mother Nature has decreed that Malta's Summers will get sweatier, and England's muggier. Time to come and getted mugged in London, where the Summer months are like a Maltese September at its worse (riħ isfel, wind downstairs; but it loses something in translation , somewhat. Like Johnny's flip-flops, and the rest).

I was always under the impression that 'seiches' is another word for tide. When I was a student( long long time ago) we were taught that Malta does not experience tides but we have what we call seiches.

2 story high waves ?? i think not ! I was in Xemxija looking at my boat's mooring and i can assure you if the swell had been that high , most of the boats in the inner side of xemxija would be in Pwales right now ! from what i saw it was more like a metre , giving allowance to the fact that i might have broken up somewhat in Xemxija that in Sliema might have been twice that amount but not more

Let us not get all dramatic. It just waves like we see when the season changes..............Just be careful out there.

And when I foolishly thought it was a sign that this horrid, brutal summer was coming to an end! Wishful thinking. A lot of people now wish for this summer to be pushed out and we enter an early autumn, yes let the freaky waves give the sea fronts a good pounding by the gale force winds and rain and much cooler temperatures.

Waves like these have been hitting our shores throughout the years and there is nothing particularly weird about them.
The problem is that we keep occupying areas that are subject to these kind of natural phenomena and what years ago was unnoticed by most people, today these phenomena have suddenly become hazards especially in areas like the Sliema shore which is packed with people.
We have to learn to respect nature and that the sea is constantly moving and can be as dangerous as it is beautiful.

Sliema sea fron is a very unpredictable area, people should be aware of such freak waves as we seem to get this every year and one day its going to be IT. the giant of all giants.

What's that got to do with this phenomena? Many cosatlines have similar underwater features but these have nothing to do with the subject of this article.

If one is on 3 or 4 mts. boat say 200 mts. out at sea and see such a wave coming what is the best thing to do,.....increase speed and ride it like a surf board or face the wave at full speed.Knowledge can save lives.

If you're out in deep sea, you would barely notice that a tsunami wave would have passed beneath you, dismissing it as simply as a disturbance in the sea but nothing to worry about. It's when the wave reaches shallow waters that it manifests it's true power and a 200m wave is an absolute rarity even then - we're talking here about such a height being reached once every hundreds of thousands years if not millions as archeaological finds so far confirm. Other than that, 200m waves out in deep water do occur... but only in movies.

Seiches can also be induced by tsunami, a series of waves generated in a body of water by a pulsating or abrupt disturbance that virtually displaces the water column....nothing to worry about if you're safe & sound 10 miles away from the shore!

The comment about large catamarans is interesting. It was found in an English port some time ago that mysterious undertows appeared around the time large catamaran ferries entered. The catamaran did not appear to be making waves but further investigation proved that although the surface appeared calm, the ferries had created large undertows which tore yachts from their moorings.
