A local resident has sent this .."From memory this "Boundary" fault has a down throw of 1 000 feet 300m. I think its the result of isostatic balance. (The earth crust is floating on the mantle. During the ice age, 10 000 years ago, Cumbria land was covered with 600m of ice which pushed the land down. This ice was not present over the sea. Since, the ice melted, the mass of ice removed, the land, Lake District has been rising.

There is another fault, The Annie Lowther Fault running roughly North south up the Duddon Estuary, & separating Hodbarrow Hematite Mine; the Old Mine from the new Mine. Has a down throw of 30m. 23 million tons of Hematite removed. Now the RSPB reserve. Duddon Estuary SSSI & Ramsar international wet land site.)

The shaft at Moorbank near Haverigg is 590ft deep. The Old Mine shafts were less deep.

In the 80s a fight with Blue Anchor Cumbria & developers (See BA Skegness) large parts of the site, 177 acers, was ruled out as a caravan site due subsidence.

Hodbarrow Mine is reclaimed from the sea. It had two sea walls both failed. The

third, Outer Barrier, 120 years old is failing. This barrier is is Millom & Haverigg sea barrier. Much of Millom is built on reclaimed tidal mud flats.....when the barrier fails much of Millom & Haverigg will be inundated. The caravans on the Moorbank area of the Mine are metres BELOW 'high water springs'.

The 'Outer barrier' 'cut off' is mild steel. Pile driven, it some times did not seal driven into shingle. Outside this steel is 'puddled clay' & this is protected by concrete blocks. These blocks are breaking up. Rising storm sea water will wash the clay away. There are several signs of subsidence on the Outer Barrier & in the Old Mine area.

At Moorbank, a caravan site of top Moorbank filled shaft. Near is a large 40metre

wide, filled, subsidence hole, near Steel Green House.

Note; the Old Mine, East of Annie Lowther Fault was not back filled with sand, There are huge voids, Pillar & Stall, covered by a limestone pie crust, some of these are supported by 'wood rises'

At Haverigg Pool, there is a 'New', 30 years or so, sea wall. Before this wall was built much of Haverigg used to flood to the seventh step in peoples houses. The flood water will come up under the walls, as did the sewage to flood housing. Millom & Haverigg sewage, possibly the Prison Camp as well has to be pumped to the Sewage works. There is no separation between foul & surface water. Rain means untreated sewage direct to the sea.

Now the water rises to about 100mm from the top of this wall. Waves slop over.

'Pool Side' Beck is tidal almost to Silecroft about, three miles. Waingate Bridge hamlet road floods to about 600mm.

There is a grassed earth sea barrier running north, Millom to Duddon Bridge.

High tides here are close to topping this embankment. This Barrier also protects Millom, & much of the usable farm in the Millom & Haverigg Area. Before this embankment the tide used to surround Millom Castle & much of Millom. Again, Global warming threatens much of the farm land here. As is happening world wide London Tokyo New York, etc!

At Kirksanton, north of Millom & Haverigg, site of the rejected Kirksanton Nuke station, the land is protected by sand dunes. Land behind the dunes is a flood plane, & back to Haverigg. They are building on it NOW! "

Comment from Frances McKie…. I remember that this earthquake shocked the living daylights out of the Frank Feates /Sir Denys Wilkinson team who had been sent to Galloway in the 1970s to declare that Mullwharchar was an ideal spot to test drill for a high level nuclear waste dump...because it was so stable..... etc...The earthquake happened just before the opening of the planning inquiry in Ayr in which we were not allowed to consider the risks of nuclear waste dumps...but only the impact of test drilling. Then we were leaked the letter which confirmed they were in Galloway primarily because we were sparsely populated, unsophisticated and unlikely to make a fuss. In other words...they thought they could get away with it. There is no science involved in 2025 either. This hole is to hide the stuff...that's all . They know it will leak .... could there even be critical mass????They don't care ....they figure Cumbria is easily sorted with more economic blackmail...remote and expendable...just like Galloway and Caithness. The nuclear lobby has taken over in Westminster and the two great white elephants at Hinkley and Sizewell are going to make a lot more uncontainable nuclear waste. https://pubs.usgs.gov/publication/70169217
