#Tsunami - New Zealand authorities have urged people in low-lying coastal areas to reach higher ground after a tsunami was trigged by a 7.5 magnitude earthquake and a series of strong aftershocks in the country’s South Island.

No injuries have been recorded thus far amid reports of widespread damage after the earthquake and this morning (Sunday 13 November) around 11am Irish time, according to RTÉ News.

TVNZ reports that tsunami waves up to one metre have been noted in Christchurch, some 90km south of the earthquake’s epicentre, as residents in Wellington, on the southern end of North Island, are urged to evacuate.

#Earthquake - Just a few weeks after the Bristol Channel was stirred up by a 4.1 magnitude earthquake, TheJournal.ie reports of tremors felt in Ireland's south-east yesterday evening (18 March).

No damage has been reported on the relatively minor quake, the magnitude of which is awaiting confirmation from Irish seismologists.

But the tectonic trembling was felt in many parts of Wexford, and detected as far away as Wales across the Irish Sea.

That may put offshore sailors on alert over the coming weeks, following as it did not long after the Bristol Channel quake, not to mention a 2.6 magnitude rumble off the Cork coast late last year.

TheJournal.ie has more on the story HERE, including a link to a questionnaire for anyone who believes they felt last night's quake.

#Offshore - Offshore sailors had best beware of some unusual tectonic activity between Britain and Ireland as of late, with the Bristol Channel experiencing its largest ever earthquake last month.

According to Met Éireann, the 4.1 magnitude quake on 20 February had an epicentre between Ilfracombe in Devon and Swansea in South Wales, and could be felt more than 200km away as far east as Guilford in Surrey.

"Most people described the shaking strength of the earthquake to be either weak or moderate, with mainly a trembling effect," said Met Éireann, "whilst others described the effect as swaying or jerky" and many reported rattling windows and shaking crockery.

There are as far no reports that the quake was felt across the Irish Sea here in Ireland, but experts will be vigilant for any further trembles beneath the waves...

#EARTHQUAKE - The North West region experienced its biggest ever earthquake this week in an event that poses “very interesting questions for geologists”.

The magnitude 4 quake on the morning of Wednesday 6 June, which was epicentred close to the Corrib Gas Field off the coast of Co Mayo, resulted in tremors felt from Sligo to Galway and numerous reports of houses shaking, as The Irish Times reports.

Minister for Energy and Natural Resouces Pat Rabbitte said all evidence pointed to the incident being a “naturally occurring earthquake” and emphasised there was “no link” to works on the Corrib field.

Experts from the British Geological Survey said it was "not a warning of anything bigger to come".

However, Tom Blake of the Irish National Seismic Network (INSN) said that the "moderate" quake was “significant” in that it challenged existing information about seismic activity in the region.

Shell EP Ireland said the seismic survey had not started and it had “no reason to believe that this event has had any impact on the sub-sea infrastructure”.

“However, as a precautionary measure, a visual inspection of the offshore infrastructure will be carried out in the coming days,” it said.

Ireland's biggest earthquake on record was in 1984, when a magnitude 5.4 quake struck off Wales, causing some structural damage along the east coast.

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
