7.3 quake hits Indonesia waters (tsunami possible)

JAKARTA — A 7.3-magnitude quake hit Indonesian waters, off the Moluccas, this morning (Nov 15) and has the potential to generate tsunami waves along nearby coasts, a monitoring agency said.

According to the US Geological Survey (USGS), the quake hit 154km northwest of Kota Ternate at a depth of 47km.
There are no immediate reports of casualties or damage.
The Pacific Tsunami Warning Center said the quake could cause hazardous tsunami waves within 300km of the epicentre along the nearby coasts of Indonesia and the southern Philippines. Waves could reach up to a metre or less, it said.
The nearest communities of Tabukan Tengah on North Sulawesi island could be at risk within an hour or so if a tsunami occurs, the agency said.
The waves could also reach as far as Taiwan, Okinawa in southern Japan, the US territory of Guam, Papau New Guinea, Solomon Islands and the Marshall Islands in the Pacific within the next six hours, it said.
Another quake measuring 6.2 was recorded soon after off Indonesia’s Sulawesi, according to the USGS.
The world’s largest archipelago, Indonesia is prone to earthquakes due to its location on the Pacific Ring of Fire, an arc of volcanoes and fault lines in the Pacific Basin.
In 2004, a monster temblor off Aceh shores triggered a tsunami that killed 230,000 people in a dozen countries. Most of the deaths were in Aceh.

Mediterranean, North Atlantic prepares for UN-backed tsunami warning system test -- (Simulations will be carried out between 28 and 30 October)

UN, 23 October 2014 – Some 20 nations with coastlines on the North Atlantic, and Mediterranean and Black Seas are set to participate in a United Nations-supervised tsunami warning exercise to improve their ability to respond to an alert and enhance regional coordination in the event of a disaster.

In a press statement released today, the UN Educational, Scientific and Cultural Organization (UNESCO) – the body coordinating the warning test since its first implementation in 2005 – reported that four tsunami simulations will be carried out between 28 and 30 October in an effort to assess the overall reactivity of countries participating in the Tsunami Early Warning and Mitigation System for the North-eastern Atlantic, the Mediterranean and connected seas (NEAMTWS).

Although tsunamis are not as frequent an occurrence in this area of the globe as they are in the Pacific Ocean, the shores of the Mediterranean and North Atlantic are densely populated prompting concern that tsunami shockwaves could strike and cause widespread damage and fatalities. In 1755, for instance, a tsunami caused by an earthquake in the Azores-Gibraltar Fault Zone destroyed Lisbon, the capital of Portugal. 

Another devastating tsunami swept over Messina, Italy in 1908, claiming tens of thousands of lives. And, more recently, in 2003, an earthquake in Algeria set off a tsunami that struck the shores of Spain's Balearic Islands and the southern coast of France. 

UNESCO noted that due to the short distances they travel in small bodies of water such as the Mediterranean, tsunami occurrences there strike shores with “great speed.”
According to the UN body, the upcoming exercise, named NEAMWave14, is based on a scenario in which four earthquakes unleash two tsunami events in the Mediterranean, one in the Atlantic Ocean, and one in the Black Sea. 

The Kandilli Observatory and Earthquake Research Institute in Turkey, the National Tsunami Alert Centre in France, the National Observatory of Athens in Greece and the Portuguese Sea and Atmosphere Institute, will send out the alerts, kick-starting the exercise, which set to involve a wide range of countries, including Croatia, Cyprus, Egypt, Finland, France, Greece, Ireland, Israel, Italy, Lebanon, Malta, Monaco, Morocco, Portugal, Romania, Russia, Spain, Sweden, Turkey, and the United Kingdom. 

“The exercise will be an opportunity to test the efficiency of the communication systems in charge of transmitting tsunami alerts and, in some countries, to ensure that the authorities in charge of public safety are prepared to face such a threat,” UNESCO explained in its press release. 

NEAMTWS is one of four regional systems which are coordinated by UNESCO's Intergovernmental Oceanographic Commission (IOC) globally. Similar systems already exist for the Pacific and Indian oceans and for the Caribbean.

UN-organized tsunami exercise shows Indian Ocean region now ‘better prepared’

UN,  12 September 2014 – A decade after the Indian Ocean tsunami disaster, which killed nearly 250,000 people and left an arc of devastation across 12 countries, a warning system devised by the United Nations to assess communications flows and readiness procedures throughout the region is functioning “effectively,” the world body has announced after a two-day simulation exercise.

“The terrible images of the 2004 tsunami are still fresh in our memories. Ten years later, this new warning exercise demonstrates that the efforts of the Indian Ocean Rim countries to be better prepared for such disasters are bearing fruit,” said Irina Bokova, Director-General of the UN Educational, Scientific and Cultural Organization (UNESCO).


The warning system, established under the auspices of the Intergovernmental Oceanographic Commission of UNESCO, “is a major achievement of global scientific cooperation that can help to save lives,” declared Ms. Bokova in a press release.

The simulation exercise was conducted on 9 and 10 September, with the participation of 24 countries of the Indian Ocean Rim. According to the preliminary results of the simulated alert, all of the participating countries received timely tsunami advisory messages, and no delays were reported.

Notification messages were issued by the Indian Ocean Regional Tsunami Service Providers (Australia, India and Indonesia) and sent to National Tsunami Warning Centres. On this basis, most of the participating countries successfully conducted exercises involving the national tsunami warning, disaster management and main emergency response organisations.

  • UNESCO says that several countries also chose to involve the general public in the exercise, including India, Mauritius and the Seychelles, where evacuation exercises were conducted in coastal areas. Tourists and personnel were evacuated from a hotel in Mauritius.

  • A full evaluation report of the exercise will be published in November 2014.

“The Indian Ocean tsunami warning system is the result of significant international collaboration and contributions from countries all around the Indian Ocean in response to the devastating tsunami of December 2004,” said Rick Bailey, Chair of the Intergovernmental Coordination Group of the Indian Ocean Tsunami Warning and Mitigation System.

He added that countries now need to sustain the warning system, community education and response capability that have been developed across the Indian Ocean. “Countries must remain alert and prepared against the ever present tsunami threat,” he said.

The exercise, known as “IOWAVE14,” comprised two scenarios: the first simulated an earthquake with a magnitude of 9.1 south of Java, in Indonesia, on 9 September, while the second scenario simulated an earthquake with a magnitude of 9.0 in the Makran Trench south of Iran and Pakistan. In both cases, the earthquakes would have resulted in a tsunami affecting the entire Indian Ocean.

India to participate in mock tsunami drill in Indian Ocean. (is planned for 9 and 10 September)

India will participate in a two- day major mock tsunami drill in the Indian Ocean, starting Tuesday, along with 23 other countries, an official said Monday.

The drill, organized under the auspices of UNESCO's Intergovernmental Oceanographic Commission, is intended to test the Indian Ocean Tsunami Warning and Mitigation System (IOTWS), said the official.



The drill is expected to increase preparedness, evaluate response capabilities in each country and improve coordination throughout the region, a statement by the Indian government has said.

"The drill also aims at evaluating the system's operational capacity, efficiency of communication among the different concerned actors, and the state of preparation of national emergency services," it added.

Indian Ocean nations to carry out UN-organized tsunami readiness test


UN, 5 September 2014 – Ten years after the 2004 Indian Ocean tsunami, 24 countries in the region will participate in an exercise organized by the United Nations to test their readiness to address such rare but potentially destructive events. 

The large-scale simulation exercise – known as “IOWAVE14” – is planned for 9 and 10 September, and is organized under the auspices of the Intergovernmental Oceanographic Commission of the UN Educational, Scientific and Cultural Organization (UNESCO).

The exercise is intended to test the Indian Ocean Tsunami Warning and Mitigation System, which was set up in the wake of the catastrophe that struck the area on 26 December 2004.
On that day, an earthquake off the coast of the Indonesian island of Sumatra sent waves as high as 30 metres crashing into 14 countries, claiming nearly 230,000 lives and leaving around 2 million people homeless.

Next week’s exercise will comprise two scenarios: the first simulates an earthquake with a magnitude of 9.1 south of Java, Indonesia; the second simulates an earthquake with a magnitude of 9.0 in the Makran Trench south of Iran and Pakistan.
Both scenarios will simulate tsunami waves travelling across the Indian Ocean and be conducted in real time.
“The goal is to measure the capacity and response times of the various stakeholders involved to address such rare but potentially destructive events,” stated a press release from UNESCO.
The agency added that the test is designed to assess the effectiveness of communication flows between the stakeholders involved, country readiness and the efficiency of emergency procedures. 

Several countries will also include public evacuation exercises of coastal populations. An evaluation will be conducted after the exercise to identify gaps and weaknesses so as to improve the Warning and Mitigation System.
The following Indian Ocean Rim countries are participating in the test: Australia, Bangladesh, Comoros, France (Réunion), India, Indonesia, Iran, Kenya, Madagascar, Malaysia, Maldives, Mauritius, Mozambique, Myanmar, Oman, Pakistan, Seychelles, Singapore, South Africa, Sri Lanka, Tanzania, Thailand, Timor-Leste, and Yemen.

Η Ιαπωνία αναθεωρεί το σύστημα προειδοποίησης για απειλή τσουνάμι

H Εθνική Mετεωρολογική Υπηρεσία της Ιαπωνίας παρουσίασε σήμερα ένα υπερσύγχρονο σύστημα προειδοποίησης για απειλή τσουνάμι.
Όπως σημειώνουν οι ειδικοί η έμφαση θα δοθεί κυρίως στην έγκαιρη έκδοση οδηγιών για την απομάκρυνση των κατοίκων της χώρας και όχι στις πληροφορίες για το ύψος των κυμάτων, όπως γινόταν μέχρι σήμερα. 
Οι επιστήμονες αναφέρουν ότι θα είναι σε θέση να εκδίδουν την πρώτη προειδοποίηση σε εθνικό επίπεδο ότι πλησιάζει τσουνάμι μόλις τρία λεπτά έπειτα από μια ισχυρή σεισμική δόνηση.

  • 7.5-magnitude earthquake strikes off coast of Alaska; tsunami warning canceled

(CNN) -- A tsunami warning was canceled early Saturday for portions of British Columbia, Canada, and southeastern Alaska, officials said.
The warning was issued following a 7.5-magnitude earthquake that struck off the coast of Alaska 63 miles west of Craig, a town on Prince of Wales Island, and 208 miles south of the capital of Juneau, the U.S. Geological Survey said.
The size of the temblor, which struck at 3:58 a.m. ET, off the coast of Alaska was downgraded by the USGS from 7.7 to 7.5.
There were no initial reports of damage but the West Coast and Alaska Tsunami Warning Center said a small tsunami of about six inches was observed near the southeastern Alaskan town of Port Alexander on Baranof Island.
A tsunami watch for the coastal areas of the British Columbia-Washington border was also canceled.
Based on available data, the tsunami warning center said there is "no destructive threat" to Hawaii, though it warned that some coastal areas could experience larger waves and strong currents.
On October 27, a tsunami was spawned by a 7.7-magnitude earthquake that struck 86 miles south of Masset on British Columbia's Queen Charlotte Islands.
The tsunami reached all the way to Hawaii, where sirens were sounded to warn residents to get to higher ground. Visions of the devastating quake and tsunami that killed thousands in Japan in March 2011 fueled the fright, but the waves proved to be smaller and less powerful than feared.
While the warning at the time said waves could surge between 3 and 6 feet, the largest wave, measured in Kahului on the island of Maui, was about 2.5 feet above ambient sea level.

  • Τι είναι τα τσουνάμι;
Ιστορικά, τα σεισμικά κύματα του ωκεανού ονομάζονταν λανθασμένα "παλιρροϊκά κύματα". Πράγματι, αυτά τα γεγονότα δεν σχετίζονται με κανένα τρόπο με παλίρροιες. Τα σεισμικά κύματα του ωκεανού είναι σήμερα διεθνώς γνωστά ως τσουνάμι (Ιαπωνική λέξη που σημαίνει "κύματα λιμανιού"). Ένα τσουνάμι είναι μία σειρά ωκεάνιων κυμάτων τα οποία έχουν μεγάλα μήκη κύματος και τα οποία μπορούν να ταξιδεύσουν σε μεγάλες αποστάσεις. Ωστόσο, τα τσουνάμι μπορούν να δημιουργηθούν και σε μεγάλες λίμνες. Σε βαθείς ωκεανούς τα τσουνάμι μπορεί να αποκτήσουν ταχύτητες μεγαλύτερες των 800 χιλιομέτρων ανά ώρα. Τα ύψη των κυμάτων των τσουνάμι κοντά σε μία ακτή φθάνουν κατά μέσο όρο τα 9 μέτρα, αλλά έχουν επίσης καταμετρηθεί και ύψη κυμάτων πάνω από 30 μέτρα.
  •  Γιατί προκαλούνται τα τσουνάμι; Ποιες είναι οι κύριες δυνάμεις που προκαλούν τσουνάμι;
Τα τσουνάμι προκαλούνται κυρίως από σεισμούς μεγέθους μεγαλύτερου από 6,5 και εστιακό βάθος μικρότερο από 50 χιλιόμετρα. Ωστόσο, δεν δημιουργούν τσουνάμι όλοι οι υποθαλάσσιοι σεισμοί, καθώς αυτό εξαρτάται από την φύση και το μέγεθος της μετατόπισης του νερού επάνω από το επίκεντρο.
Οι κύριες δυνάμεις που προκαλούν tsunamis είναι οι ακόλουθοι:
Κατακόρυφες μετατοπίσεις του θαλάσσιου νερού που προκαλούνται από υποθαλάσσιους σεισμούς, οι οποίες προκαλούνται από απότομη μετατόπιση ενός ρήγματος στο βυθό της θάλασσας.
Οριζόντιες μετατοπίσεις της στήλης του ύδατος ως αποτέλεσμα των δονήσεων του σεισμού (οι σεισμοί που συμβαίνουν στην ξηρά μπορεί και αυτοί να δημιουργήσουν ένα τσουνάμι, αν συμβούν κοντά σε ακτές).
Ηφαιστειακές εκρήξεις στην θάλασσα οι οποίες μπορεί να μετατοπίσουν το θαλάσσιο νερό με σχετική βιαιότητα.
Κατολισθήσεις που γίνονται στον πυθμένα των θαλασσών (αυτές ωστόσο συνήθως δεν δημιουργούν τσουνάμι μεγάλου μεγέθους).
  •  Πού δημιουργούνται τα περισσότερα τσουνάμι;
Από τα καταστροφικά τσουνάμι, το 90% συμβαίνουν στον Ειρηνικό Ωκεανό, κατά μέσο όρο περισσότερα από δύο κάθε χρόνο. Τα τελευταία 190 χρόνια τα νησιά της Χαβάης υπέστησαν περισσότερα από 150 τσουνάμι και οι καταστροφές πολλές φορές ήταν εκτεταμένες. Οι Η.Π.Α. υφίστανται κάθε χρόνο περισσότερα από 26.000.000 $ σε υλικές ζημιές, ενώ 500.000 άνθρωποι ζουν σε περιοχές της χώρας που απειλούνται από τσουνάμι ύψους 15 μέτρων και 1.200.000 άνθρωποι απειλούνται από τσουνάμι ύψους άνω των 30 μέτρων. Η δυτική ακτή καθώς και τα νησιά της Χαβάης παρουσιάζουν το μεγαλύτερο κίνδυνο. Στις λεκάνες του Ατλαντικού και της Μεσογείου εμφανίζονται λιγότερο συχνά τσουνάμι. Για αυτό το λόγο οι κατάλογοι των τσουνάμι δεν είναι ολοκληρωμένοι και επομένως οι περίοδοι επανάληψης για την περιοχή είναι άγνωστοι. Ωστόσο, η ηφαιστειακή έκρηξη της Σαντορίνης που χρονολογείται γύρω στα 1650 π.Χ. προκάλεσε τσουνάμι το οποίο ταξίδευσε σε ολόκληρη την ανατολική Μεσόγειο και ο σεισμός που έλαβε χώρα το 1775 κοντά στη Λισσαβόνα, Πορτογαλία, υπολογίζεται ότι προκάλεσε 25.000 νεκρούς από ένα τσουνάμι στην πόλη και δημιούργησε κύματα που έφθασαν μέχρι την Καραϊβική.
  • Ποια είναι επίδραση των τσουνάμι;
Τα τσουνάμι συχνά γίνονται επικίνδυνα καθώς πλησιάζουν στην ακτή. Όταν φθάσουν, μπορούν να μεταφέρουν τα μεγάλα πλοία πολλά χιλιόμετρα μέσα στην ξηρά και να πλημμυρίσουν τις ακτές. Τα τσουνάμι μπορούν να δημιουργηθούν από ένα γεγονός το οποίο μετατοπίζει ένα μεγάλο όγκο ωκεάνιου νερού, όπως ένας σεισμός, ηφαιστειακή έκρηξη, ή κατολίσθηση.
  • Πώς γίνεται η πρόγνωση των τσουνάμι; Τι είδους όργανα χρησιμοποιούνται;
Οι προγνώσεις των τσουνάμι λαμβάνουν χώρα με δύο τρόπους. Ο πρώτος τρόπος είναι η χρησιμοποίηση υπολογιστών προκειμένου να προβλέψουμε πόσο μεγάλα σε ύψος τσουνάμι είναι δυνατό να φθάσουν στην ακτή για διαφορετικά είδη σεισμών. Όταν τοποθετηθούν αυτά τα δεδομένα στους χάρτες, οι προβλέψεις αυτές δίνουν τις καλύτερες οδούς διαφυγής αν συμβεί ένα τσουνάμι.
Ο δεύτερος τρόπος πρόγνωσης γίνεται από κέντρα προειδοποίησης τσουνάμι τα οποία προειδοποιούν αμέσως μετά από τη δημιουργία ενός σεισμού ο οποίος μπορεί να προκαλέσει ένα επικίνδυνο τσουνάμι. Χρησιμοποιούν σεισμογράφους για να υπολογίσουν τη δύναμη και την θέση ενός σεισμού. Η εμπειρία που έχει αποκτηθεί στο παρελθόν υποδεικνύει στους επιστήμονες ποιες περιοχές στην ακτή παρουσιάζουν το μεγαλύτερο κίνδυνο να χτυπηθούν από τσουνάμι. Χρησιμοποιώντας υπολογιστές, μπορούν επίσης να ενημερώσουν για το πόσο χρονικό διάστημα θα χρειαστεί για φθάσουν τα κύματα των τσουνάμι σε διάφορες περιοχές.

  • Tsunami warning issued after Japan earthquake
  • Meteorological Agency says earthquake with a preliminary magnitude of 7.3 struck off the coast of Miyagi.


Authorities in Japan have issued a warning of a possible tsunami after a strong earthquake jolted the northeastern part of the country.

The Japan Meteorological Agency says the earthquake with a preliminary magnitude of 7.3 struck in the Pacific Ocean off the coast of Miyagi prefecture at 0818GMT on Friday. The epicentre was 10 km beneath the seabed.

The warning said the tsunami could be as high as 2 meters.

Buildings in Tokyo swayed for at least several minutes.

Sayaka Matsumoto, communications officer, at the Japan Red Cross told Al Jazeera that she felt "quite [a] large shake” at her organisation’s headquarters in Tokyo.

Matsumoto said the quake felt about “half the size” of the devastating March 11, 2011, earthquake and subsequent tsunami that left more than 15,000 people dead.

  • Erdstöße in Katastrophenregion: Tsunami-Warnung nach schwerem Beben in Japan
Wieder erschüttert ein starkes Erdbeben den Nordosten Japans. Die Behörden haben eine Tsunami-Warnung ausgegeben. Die Erdstöße, die auch noch in Tokio zu spüren waren, rufen Erinnerungen an das Unglück von Fukushima wach.
Das Beben der Stärke 7,3 im Nordosten Japans war auch in der Hunderte Kilometer entfernten Hauptstadt Tokio zu spüren. Gebäude schwankten, berichteten Zeugen am Freitag. Das Zentrum des Bebens lag in der Nähe des Erdstoßes, der im März vergangenen Jahres einen verheerenden Tsunami ausgelöst hatte. Allerdings erwarten die Behörden diesmal keinen großen Tsunami, sondern eine Welle von etwa einem Meter Höhe in der Provinz Miyagi. Auch die Bewohner umliegender Regionen wurden zu Wachsamkeit aufgefordert. Das zuständige US-Tsunami-Warnzentrum löste keinen pazifikweiten Alarm aus.

Über mögliche Opfer oder Schäden liegen keine Informationen vor. Ob es zu neuen Schäden am havarierten Atomkraftwerk Fukushima kam, ist ebenfalls noch unklar. Nach Angaben des Betreibers Tepco besteht keine Gefahr. Auch in Fukushima wird ein Tsunami von 50 Zentimetern erwartet, meldet der TV-Sender NHK.

Nach Angaben von N24 war die Welle eigentlich um 9.40 Uhr MESZ an der Küste erwartet worden. Bisher traf sie allerdings noch nicht ein.

  • M7.3 quake hits northeastern Japan; tsunami alert issued for Miyagi

TOKYO —

A tsunami alert was issued for the northeastern Japan Friday after a powerful 7.3-magnitude undersea earthquake struck at 5:18 p.m., setting buildings in Tokyo swaying violently for several minutes.

The Japan Meteorological Agency said the epicenter was 240 kilometers east of Sendai, Miyagi Prefecture and 10 kilometers beneath the seabed.

Media reports said a one-meter-high wave could sweep ashore in an area badly hit by the March 2011 tsunami that devastated a large swathe of the northeast coast, killing thousands.

Residents of at least one town, Minamisanriku in Miyagi Prefecture, were advised to evacuate to higher ground, reports said, suggesting other towns were also affected.

A presenter on state broadcaster NHK repeatedly told viewers to get to safety.

“Remember last year’s quake and tsunami,” he said. “Call on your neighbours and flee to higher ground now!”

NHK, quoting the Japan Meteorological Agency, said the tsunami was expected to hit the coasts of Iwate, Fukushima, Aomori and Ibaraki by 6 p.m.

There was no threat of a Pacific-wide tsunami, U.S. monitors based in Hawaii said. Officials in both Indonesia and the Philippines south of Japan said there was no threat of a localised tsunami.

Nuclear plant operator Tokyo Electric Power told AFP there were no reports of any problems at the crippled Fukushima nuclear plant.

“No abnormalities have been recorded on instruments at Fukushima Daiichi nulcear plant’s six reactors,” a TEPCO spokesman said.

“All workers were ordered to take shelter inside buildings at the Fukushima plant. No abnormalities were confirmed with the radiation monitoring posts at the Fukushima plant. No abnormalities were seen with the water processing facilities.”

Prime Minister Yoshihiko Noda was heading to his office where he would be monitoring the situation, Jiji Press said.

Japan Railways East temporarily suspended Shinkansen bullet train services to check any damage, Jiji said, while Haneda Airport near central Tokyo was reported to be operating normally. Narita airport briefly closed its runways.
