#Kıbrıs’taki #depremlerin çoğunun kaynağı adanın güneyinde deniz içerisinde bulunan faylardan kaynaklanır. Kıbrıs’ta M.Ö. 26 ile M.S. 1900 yılları arasında, 8 şiddetine varan 16 yıkıcı depremin meydana gelmiştir. Bunların çoğu adanın batısındaki Papos (Baf) civarında yoğunlaşır.

1953 yılında 63 kişinin ölümüne neden olan 6.5 ve 1996 yılındaki 6,8 büyüklüğündeki depremler de Baf başta olmak üzere Magusa’ya kadar olan alanı etkilemiştir. Kıbrıs’ın depremler yönünden en aktif kesimi Baf’tan Limasol’a oradan da Larnaka ve Mağusa’ya uzanan kıyı şerididir

Kuzey kesimi oldukça sakin olan adanın #Hatay ve #Adana'ya bakan kesiminde yakın geçmişte olan depremler bu haritada verilmiştir (Drawchech vd., 2022). Deniz içerisinde ve karada olan depremler Kıbrıs kıyılarında #tsunamiye de neden olmuştur

Die Atomkatastrophe von #Fukushima wurde nicht durch den #Tsunami verursacht, sondern durch eine Vielzahl von Fehlern und Nachlässigkeiten. Das war 2012 das Fazit des offiziellen parlamentarischen Untersuchungsausschusses in #Japan. (1/3)

Das macht #Atomkraft auch heute und bei uns so gefährlich: Leichtfertig wurde die periodische Sicherheitsprüfung #PSÜ über ein ganzes Jahrzehnt (!) verschoben und Laufzeiten verlängert. Hinweise auf Haarrisse in den Reaktoren werden auf Seite gewischt. (2/3)

Dieser leichtfertige Umgang mit einer Hochrisikotechnologie ist nicht nur geschichtsvergessen, sondern gefährlich. Die Katastrophe von #Fukushima muss uns eine Lehre sein, das niemals zu vergessen und so schnell wie möglich alle #AKW abzuschalten. (3/3)

Zum verheerenden #Erdbeben in der #Türkei und #Syrien kursieren zahlreiche #Falschinformationen. Alte Aufnahmen werden aus dem Kontext gerissen und unter unter das echte Material gemischt. Einige Beispiele:

Dieses Foto eines Hundes, der neben einer unter den #Trümmern verschütteten Person liegt, ist ein Stockfoto von 2018 und nicht vom jüngsten #Erdbeben in der #Türkei und #Syrien.

In seguito al terribile #terremoto che ha colpito la #Turchia, il Dipartimento della Protezione Civile italiana ha diramato un'allerta per possibili onde di maremoto, raccomando di allontanarsi dalle zone costiere, di raggiungere l'area vicina più elevata e di seguire le

DEEP SEA VOLCANO NAMED AFTER MORDOR INTERRUPTS INTERNATIONAL SHIPPING ROUTES | The waterways of Indonesia carry 90% of the world's trade. But the volcanic activity at the Karma seamount has been making waves - literally - at an increased rate since December 14, 2021. 🔽🧵#tsunami

2. Indonesia's island volcanoes get most of the headlines, and even the research activity. Take Krakatoa, pictured here. It caused such a destructive tsunami in the 1800's that explosive activity can be alarming. And it is certainly erupting today. This is a recent photo.

3. But Krakatoa is only one of Indonesia's many erupting volcanoes. And most of them aren't even listed on this map. The map shows every volcano that has erupted in Indonesia over the last 100 years. Notice that none of them are in the sea. That's a big mistake.

Hilo

1/4
Un derrame de combustible ocurrido en La Pampilla por descarga de Buque Tanque italiano Mare Doricum puede haber ocurrido por una deficiente conexión de mangas de Refinería al Buque Tanque (caso muy inusual) por altos estándares aplicados de seguridad hace más de 20 años

2/4
Por un oleaje en la zona de carga y descarga inusual propio de marea o algún evento fortuito natural como el ocurrido tras erupción de volcán en #Tonga y género #Tsunami u #OleajeAnomalo
En este caso si puede ocurrir un derrame por que genera que mangas tuvieran accidente.

🌋 #HungaTonga 💥 Desde el sábado se esta hablando mucho de este volcán, pero...¿os gustaría conocer más sobre esta erupción? Arrancamos hilo desde el #IGNSpain sobre la erupción del #HungaTongaHungaHaapai
(👇 sigue para verlo 😉)

#HungaTongaHungaHaapai es una erupción ocurrida el 15 de enero en Tonga (pacífico sur) que ha afectado a 3 islas muy jóvenes: Hunga Tonga, Hunga Ha’Apai y una isla nueva que se había formado en medio de ambas. Las tres formaban el borde norte de una caldera de un volcán submarino

La última erupción comenzó el 21 de diciembre de 2021 y el 4 de enero ya había descendido mucho su actividad. Las columnas eruptivas habían llegado a más de 16 km de altura, cayendo ceniza en las dos islas y otras adyacentes.

Mango Island #Tonga via Airbus SPOT imagery 1/16/22. Unfortunately the inhabited part of the island obscured by clouds. It appears either survivors or debris in a spot not normally occupied by people on lower right.

Reference image from 1/14/22 of Mango Island, you'll notice the bright spot visible in the other imaging not present. I suspect survivors of the tsunami put up some kind of shelter up at the high point of the island. Tent, leanto or stretcher. Looks like at least 5-6 people too

Tough to tell 100% but I would put money on these being people around a tent or some kind of temporary structure. #MangoIsland #Tonga #tsunami

Kanokupolu #Tonga taken yesterday, 1/16/22 via Airbus SPOT #satellite. Post volcano/tsunami. High resolution image, this looks to me to be ashfall.

#Tonga taken by Airbus SPOT on 1/16/22. This is (was?) Ha'atafu Beach and Haatafu Beach Resort, but it seems to me that there are structures missing on this side (the resort appears to me to be missing, or extremely covered with ash). Possible tsunami scouring on the beach.

Reference image in Google vs. this acquisition -- you can see the big building on the top right in both images, but none of the structures you'd expect at Ha'atafu Beach, Nuku'alofa itself. #tonga #tsunami #volcano

Tonga Navy appears to have just reached the island of #Nomuka

This ship (the only one transmitting satellite AIS data) came from Nuku'afola this morning, when officials said they would be sending the Tonga Navy to the outer islands.

Found this video I had missed earlier from this location (FB Live... shot just as the seas were retreating. Hope this person made it up a hill, what was coming as likely worse)

Postdisaster msg from HRH Princess Latufuipeka (daughter of King Tupou VI & #Tonga’s High Comm to 🇦🇺). Focus on gratitude, faith &taking refuge in God. This type of reaction overwhelmingly present on Tongan social media atm. Not what you’d usually get elsewhere,but consider (1/4)

#Tonga is one of the most vulnerable countries in the entire world to natural #disasters & climate change. In less than 4yrs it has weathered 2 max strength (Category 5) cyclones, a pandemic and a 1 in 1000yr volcanic eruption + resultant earthquake & #tsunami. (2/4)

And each time, people pick up & carry on. Often with humour & while singing a hymn! I’m no expert but I would think being grateful/positive, having a form of faith & relying on each other as a community helps ease the otherwise depressing mental effects of so much trauma. (3/4)

#Nomuka #Tonga via Sentinel-1 #satellite, before and after the #HungaTongaHungaHaapai volcano eruption.

This island south of Nomuka looks to have been inundated, based on Sentinel-1 radar image (darker areas = water).

@sentinel_hub

Using a new feature of @sentinel_hub here's a sequence of SAR radar before/Sentinel-2 true color before/and then SAR radar after where you can see where the reflectivity of the land has changed to water.

Wir sehen aktuell an mehreren Küsten Europas leichte Meeresspiegelschwankungen um 10 Zentimeter. Wahrscheinlich der Tonga #Tsunami, der ein einmal um Südamerika (oder Südafrika) in den Atlantik geschafft hat (Oder Meteotsunami durch Druckwelle?). Ein paar Beispiele:

Ponta Delgada auf den Azoren seit ca. 2 Uhr mit einem Peak um 40cm Wellenhöhe. ioc-sealevelmonitoring.org/station.php?co…
Cascais bei Lissabon begann etwa zeitgleich, Amplitude 20-30 cm. ioc-sealevelmonitoring.org/station.php?co… #Portugal #Tsunami

Sehr schwaches Signal in Cadiz, SW Spanien zur gleichen Zeit. Sehr unsicher ob Tsunami oder nicht. ioc-sealevelmonitoring.org/station.php?co…Ähnliches in der Bretagne, Frankreich, ein wenig später. ioc-sealevelmonitoring.org/station.php?co…

Satellite imagery reveals first losses due to the #Tonga #tsunami.
It seems that the uninhabited islands of Nuku and Tau have been completely eroded. Their larger neighbors Tonumea and Kelefesia were at least partially inundated.

Satellite imagery via @sentinel_hub #Sentinel1

@sentinel_hub

@sentinel_hub Nomuka island , North of #Tonga was also significantly affected. Its barrier islands Nomuka Iki was at least partially inundated and traces of inundation seem visible for the main town of Nomuka (400-500 people).

Interpretation is difficult.

A few more islands show traces of inundation. Unfortunately, there is not yet much data available to assess more regions.

Waiting for imagery for Nuku'alofa and the islands of Fiji.
