We know the feeling when we start to read an article titled: Some scientists have found… But this time, it’s real – it’s not just another meaningless study based on a survey of several hundred respondents. In this case, it is an inescapable fact backed by common sense. So, what is the article about? About tsunamis that are most likely to occur in the Mediterranean area over the next thirty years due to continually rising ocean levels.

The Mediterranean’s Tsunami Challenge

The climatic situation has reached an irreversible point. The point of no return. Even if the way of life on Earth changes immediately, the damage has been done. Apparently, the consequences of the long-term neglect of environmental protection are no longer avoidable. This gloomy forecast, confirmed by the United Nations Educational, Scientific and Cultural Organization (UNESCO), urges coastal cities to prepare by putting in place the necessary precautions. The Mediterranean will therefore have to battle against the water element, and given the extent to which it poses a danger to the cities themselves and their inhabitants, preparations must begin immediately.

The countries affected by frequent storm surges are well aware of the imminent risks. But the situation may differ in others where sudden torrential rains have not yet typically occurred. The UNESCO warning targeted Mediterranean territories, led by cities such as Marseille (France), Istanbul (Turkey), and Alexandria (Egypt). In addition, other cities will have to face the same problem. In total, more than forty sites in twenty-one countries should be included in the special UNESCO programme. The preparatory programme was launched ahead of the UN Ocean Conference in Lisbon in July 2022.

Urgent Preparations for the Mediterranean’s Rising Tsunami Risk

To make matters worse, scientists have found evidence of a yet overlooked geological fault in the Mediterranean Sea (near Crete). The spot can produce earthquakes and subsequent tsunamis as powerful as the one that destroyed Alexandria in 365 AD. Such quakes are recorded approximately every eight hundred years. Since the last recorded activity was 1300 years ago, it is predicted to recur soon. According to a model developed by seismologists at Cambridge University, the tsunami waves thus generated could flood the northern coast of Africa, southern Greece, and Sicily and continue up to the Adriatic Sea as far as Dubrovnik.

Plan Z Seems To Be the Only One

Plans A to Y should have been made at a time when these anticipated events could still have been avoided. Today, however, Plan Z will have to be the only effective. The challenge for the territories included in the programme is to develop a plan to reduce the potential risk of storm surges by 2030. This should also include the identification of locations at risk, together with the publication of relevant maps. As part of these preparations, UNESCO has also set up twelve tsunami warning centres. Five of them are located in the Mediterranean.

Bernardo Aliaga, a UNESCO tsunami expert, said that tsunami risk is greatly underestimated in most areas, including the Mediterranean, and that there are still gaps in preparedness that need to be addressed. Residents in the affected areas will reportedly be provided with evacuation plans and early warning systems implemented through electronic sirens or mobile apps.

Early Warning Solutions as Part of the Plan

What does it all mean? It is more complicated than it may seem, and the preparations that generally take time will have to be made in a fraction of that time. Early warning systems are only a fraction of the equation anyway, the outcome of which is to help reduce the negative impact of what we can no longer change. Telegrafia offers specialist tsunami warning solutions and can become part of the global relief effort. Suppose it affects your area or country – although we can’t stop the danger, we are here to create an imaginary shield to protect you against it.

Summertime, the holidays and nice weather came, but accompanied by a series of totally undesirable events during the last years. These are heatwaves, and even worse: the fires. Our forests are on fire. If you do not trust, ask in Spain, Romania, Portugal, France, Italy, Croatia and Greece, which all suffer the worst consequences of the most destructive fires. During this year, more than 600,000 hectares were burned throughout Europe and 94.7% thereof belong to the countries mentioned above.

Estimates of Program Copernicus EFFIS* for EU Countries

As far as the fires in Spain concerns, already now the statistics indicate the year 2022 as the worst within this century. By July, approximately 230,000 hectares were burned there – in comparison with the total of 189,376 hectares burned by all 255 fires broken out in 2012 according to EFFIS* data for the entire 2012.

EFFIS* Annual Statistics for Spain

What is happening? Why so many fires are occurring?

It is very complicated to answer these questions as it is necessary to take into account that we are talking about a continent with very diverse climatic conditions, orography and features, and also because the experts themselves advocate variable opinions. Therefore, we will focus mainly on Spain (the most affected, with 30 big forest fires by the end of July), and to those points where the majority coincides apparently:

• The climatic change is real: among others, the heatwaves with temperatures over 40 °C, strong winds and droughts make possible another adverse meteorological phenomenon which spread the fires and/or makes more difficult their extinction.
• In Europe, there are more and more lightnings, which constitute another meteorological phenomenon causing fires. According to Blitzortung data, in the whole Europe, there were registered more than 1.5 million lightnings or electric storms just during the last week of July.
• There are no informative and educational campaigns and projects aimed at the population. Those might reduce the number of fires caused by negligence or accidents. And obviously, also the number of those deliberate
• In many Spanish municipalities with fire risk, neither act on forests nor the basic directive on planning of civic protection are observed. There are neither emergency plans nor plans of protection against forest fires, or, if they exist, they are not implemented.
• As many experts say, we miss sustainable forest management. This should include not only the forest cleaning and fires extinction, but also the fires prevention and dealing with the rural exodus…
• And at last, another cause of fires is in the spreading of the previous fires.

How can Telegrafia help with the forest fire management?

To put it simply, the forest fire management consists of four phases: prevention, preparation (prediction), response and recovery. Our intervention would support the second and third phases as our electronic sirens can be duly adjusted for an efficient response to fires.

The summary of the sirens use in several points is as follows:

• The sirens purpose is to speed up the response. They warn immediately, and provide more time for evacuation, thus avoiding potential victims and damages.
• In case of appropriate layout of static sirens (Pavian, Gibon or Bono) and use of mobile sirens (Pavian Car or Screamer Car), big area can be covered, and especially, remote residential zones can be reached as well as those with difficult access.
• Modern sirens are highly reliable. They have a lot of programming modes, they may emit various sounds even for different natural disasters, thus guaranteeing the population in the neighbourhood will be aware of the unambiguously.
• The installation and maintenance costs for electronic sirens are relatively low.

As proven by the experiences in many countries, notwithstanding the most advanced technologies, the electronic siren keep playing the fundamental role as warning systems in case of natural disasters. While performing detailed survey of the terrain, we can guarantee that the sirens are the system, which the most number of the affected will be aware of. If you wish so, Telegrafia may help you to design a suitable and reliable combination of electronic sirens, and configure them in a manner preventing effectively the biggest number of victims and damages.

In today’s world, people can hardly imagine their lives without smartphones and mobile applications. Apart from traditional telephoning, these help us navigate our journeys, take photos, or provide our everyday immediate access to e-mail and the Internet. Recently, a new idea has appeared to supplement such clever devices with another functionality, namely the mass warning, to issue warning against imminent dangers via SMS (i.e. by texting short messages to people in emergency situations) or mobile applications. But is it really a wise idea?

Simple and seemingly brilliant idea

The idea of public mass warning using the SMS seems to be simple and brilliant. Almost any person in the highly developed world owns a mobile phone, so why to invest money in an independent warning system with modern electronic sirens? It should be sufficient to use the commercial mobile operators’ networks and supplement the mobile phone with a new system that would text and send warning messages to the general public (well, only to those who own mobile phones, in fact) in a case of impending danger, describing its character. Quick, simple, and seemingly inexpensive. However, it is necessary to draw attention to some unaware fundamental shortcomings on the part of such solution.

Unpleasant details that really matter

The application of mass warning systems based on the SMS or, in general, on mobile networks and smartphones, involves many serious risks, both on the side of mobile networks and on the side of end-user devices. The main problem is that mobile operators’ networks are designed and built for ordinary, everyday use in standard conditions. In other words, for situations when everything works well. When designing and building such networks, it was never taken into account that they should be resilient enough and fully functional in extraordinary situations and prepared for large-scale emergencies, such as dangerous tsunami waves, volcanic eruptions, serious industrial accidents, and severe floods. And, we do not mean only their projected life, but also their reliable operability. Even today, for example, it is quite common that mobile networks in big town centres get overloaded and prevent their normal operation. Is it not incredible just to imagine that this network should suddenly be capable of sending thousands of warning messages to so many mobile phones in a couple of seconds?

At least, to approach the mobile network parameters to the standards currently effective for real mass warning systems (i.e. make such systems fully operative for a minimum of 72 hours after a power failure, equip them with two independent communication channels for activation, etc.), a new and relatively costly infrastructure must be built. Consequently, we have to face another problem: because end-user devices to receive warning messages are mobile phones, the system wholly depends on the ground radio infrastructure. It is a standard for modern electronic sirens to be activated by at least two independent communications channels, e.g. via a dedicated radio network and satellite channel. There is no such possibility in mobile phones. Moreover, have you ever heard that one of the first measures taken after a terrorist attack is the immediate deactivation of the public mobile network? This is to prevent remote activation of laid bombs or make the escape of survived terrorists harder; however, all mobile phone owners are left abandoned at the same time.

Last but not least, there are other problems arising from the very nature of the system. As the system has certain limitations, warning messages in some countries can be sent to specific recipients only based on their invoice particulars, not on their actual locations at the time of emergency. This means that the system fails to send a warning message to a tourist staying at an endangered area, albeit not normally residing there. On the other hand, a company sales representative, currently negotiating a business deal thousands of kilometres away from an endangered area, gets frightened by a warning message despite their not being endangered at all.

While some of the limitations of the mobile network can be partially removed by expensive and massive investments in the existing infrastructure, the greatest problem appears on the side of the recipient and their discretion about how to behave. The operation of modern electronic sirens is supervised by the relevant national authorities and message recipients, mostly civilians, have no control over the broadcasting of warning messages. So what happens to people who have dead batteries in their mobile phones? And what about ladies whose mobile phones rest too deep in their bags to be heard? What is more, what about people who go to the toilet and do not take their phones with them? Or what happens to managers in a meeting whose phones are set in the “Do not disturb” mode? Or people who will prefer to finish reading e-mails from their bosses instead of reaching for their beeping phones? Or people (including the author of this article) who switch off their phones every evening for the whole night, and this is not only because of electromagnetic smog?

Have you ever woken up at 3:00 a.m. only to immediately read a text message in your smartphone? At least, unless you belong to a group of people who turn off their smartphones before going to bed.

If an electronic siren starts screaming at 3 o’clock in the morning, being accompanied with a voice message about the nature of the danger and some more important information, you will certainly wake up and be on full alert immediately. In contrast, when did you last wake up at 3:00 a.m. only to read a text message on your smartphone? The meaning of warning siren sound is obvious to everybody. However, if a device normally and primarily intended for daily communication and entertainment is used for warning purposes, from the psychological point of view, this is a major and unjustifiable risk. And, in conclusion, are only people who decided to own smartphones worth warning against danger?

Test failure in real conditions

Mass warning systems based on mobile networks and smartphone technologies have been in operation in many countries, and so far the experience has shown unimpressive results. For example, during the terrorist attack in Nice, France, the people in danger received a warning message from the SAIP (Système d’alerte et d’information des populations) system as late as unbelievable 90 minutes following the attack, making the message practically useless. Many others did not receive the message during the whole emergency period. Moreover, regarding the scale, it was only a minor and isolated attack that did not disable the communications infrastructure, power supply, or other technology necessary for any similar system to remain operational at all.

Should we use mass public warning via SMS at all?

Mass warning of the general public against emergencies by using the SMS system may first sound like a breakthrough and trendy solution, well worth the 21st century. Albeit, only until the moment when all its benefits and shortcomings are realistically and professionally assessed. It may be advisable for rich countries to use the SMS system as a supplement to real mass warning devices complying with all relevant standards. If used as the only mass warning system in case of emergency, this solution can be without any exaggeration regarded as a risky behaviour, something of a gamble with human life. We can only hope that no large-scale catastrophe is needed to make all persons responsible aware of the consequences.

The New Caledonia tsunami warning system project in detail

Name of the project: Population tsunami alert system in the French Pacific
Country: New Caledonia
Goal of the project: Equipment of the French National Civil Security with a global tsunami alert system for the evacuation of people along the high-risk locations
Number of tsunami sirens: 60 Pavian tsunami sirens
Date of maintenance: 2015

Lifou after successful tsunami siren maintenance

The island of Lifou was discovered by a French traveller, Jules Dumont d’Urville, in 1857 and nowadays it is known to many tourists for its enticing nature, stunning beaches, soft golden sand, and pristine and picturesque landscape. It is a home to approximately ten thousand people. The irregularly shaped (81 km long and 16 to 24 km wide) island is an overseas Pacific territory of France, located in the archipelago of New Caledonia – Loyalty Island Province.

The duality of the island: tropical beauty and the threat of tsunamis

The beauty of transparent water and tropical aura lures numbers of tourists to the place every year where they find a pleasant rest and relief from the monotony of daily routines. In addition to its beautiful face, the island has its bad side as well, which results from its dangerous location. The Pacific is geologically one of the most active fields on Earth, producing dangerous tsunamis. They take a deadly toll: since the beginning of the 20th century they have killed thousands of people around the Pacific Ocean. Thanks to improved tsunami detection methods, authorities are able to take action more effectively today. Numerous procedures and policies supported by high-tech solutions have been implemented with a single goal – to warn the population before the wave reaches land in order to prevent major destruction and loss of life. Tsunami sirens have become an indispensable part of the warning ecosystem on the island. Installed in the most endangered areas, high-output tsunami sirens are now able to transmit both well-audible alarm signals and live-voice messages if any emergency should arise.

Regular maintenance is an activity that ensures that people trust warning systems. By performing routine actions which keep the devices fully functional, they are 100% confident that tsunami sirens are ready for use in need.
