Minor injuries were also reported in the areas surrounding the epicentral area, and rockslides occurred at Tremadog in Gwynedd.The 19 July earthquake was followed by many aftershocks in the following months, the largest measuring 4.3 on the Richter scale, which itself was felt as far away as Dublin, in Ireland.

The parish was abolished in 1934 and incorporated into Llanystumdwy. The village lies 4 miles (6.4 km) north east of Pwllheli and is close to the village of Llangybi, a holy well and the mountain of Carn Pentrych. A well-preserved 15th-century manor house at Penarth-fawr is maintained by Cadw, and another ancient monument Plas Du (Welsh: Black Place) is a well-preserved, substantial sub-medieval gentry house. It also has important historical associations; it was known as the centre of the Roman Catholic faith in the region and was the home of Thomas Owen, High Sheriff of Caernarfonshire from 1569, who was imprisoned for sheltering missionary priests in the house in 1571. "The village is pleasantly situated in a fertile plain, and the neighbour-hood partakes of the pleasing scenery which prevails in this part of the country. The living is a rectory not in charge, annexed to that of Llangybi, in the archdeaconry of Merioneth, and diocese of Bangor, and in the patronage of the Bishop of Bangor. The church, dedicated to Saint Garmon, is an ancient and spacious structure in good repair : some additional windows have lately been inserted, previously to which alteration the interior was very dark." Samuel Lewis, Topographical Dictionary of Wales (1833)

Llangybi (English: Cybi's Church) is a village and former civil parish in the Eifionydd area of the Welsh county of Gwynedd, near Llanarmon. The parish was abolished in 1934 and divided between Llanystumdwy and Llannor. St Cybi's church is a grade II* building.As well as various menhirs, tumuli and stone circles in the countryside around, the village is particularly noted for a holy well, Ffynnon Gybi (English: St Cybi's Well). According to local tradition the girls who wished to know their lover's intentions would spread their pocket-handkerchiefs on the water of the well, and, if the water pushed the handkerchiefs to the south they knew that everything was right and that their lovers were honest and honourable in their intentions; but, if the water shifted the handkerchiefs northwards, they concluded the contrary. A reference to this is made in severe terms by a modern Welsh poet. "This parish, which derives its name from the dedication of its church to Saint Cybi, an eminent British saint, who flourished towards the close of the sixth century, is pleasantly situated in the south-western portion of the county, and nearly in the centre of the promontory which separates Cardigan bay from the bay of Carnarvon. It is of very considerable extent, and the lands are mostly enclosed and in a good state of cultivation : the surrounding scenery is pleasingly diversified, comprising some fine views of the adjacent country, which abounds with varied and picturesque beauty. At Pontrhyd Goch is a slate quarry, which, however, is worked only on a limited scale, the slates being of rather an inferior quality, and the demand for them confined principally to the immediate neighbour-hood. The road from Carnarvon to Pwllheli passes through the parish.

Llanaelhaearn is a village and community on the Llŷn Peninsula in the county of Gwynedd, Wales. The community includes the larger village of Trefor and has a population of 1,067, increasing to 1,117 at the 2011 Census.

Tre'r Ceiri (Welsh: [treːr ˈkɛiri]) is a hillfort dating back to the Iron Age. The name means 'town of the giants', from cewri, plural of cawr, 'giant'. The settlement is located 450 metres (1,480 ft) above sea level on the slopes of Yr Eifl, a mountain on the north coast of the Llŷn Peninsula in Gwynedd, north-western Wales. Evidence suggests the settlement was first built around 200 BC, though most of the archaeological finds date from AD 150–400, showing the site continued as a settlement during the Roman occupation.Tre'r Ceiri is one of the most spectacular ancient monuments in Wales. The settlement is surrounded by stone walls that are largely intact, and which reach up to 4 metres (13 ft) in some places. Within the walls are ruins of about 150 stone houses, which would have had turf roofs. During Roman times, it may have housed up to 400 people. Historian John Davies suggests that because the settlement is so far above sea level, the huts served as habitations for summer shepherds who also had winter dwellings in the lowlands.In modern times it was first brought to popular attention by Thomas Pennant in his Tours of Wales. Its location and importance have attracted visitors for years. The hillfort has recently been the site of conservation work and footpath maintenance. An extensive survey was made in 1956.

The Trefor Quarry railway was an industrial, 1 ft 11+1⁄2 in (597 mm) narrow-gauge railway connecting the Trefor granite quarry with the pier at Llanaelhaearn on the Llŷn Peninsula.

Yr Eifl, sometimes called the Rivals in English, is a group of hills on the north coast of the Llŷn Peninsula in Gwynedd, Wales. On a clear day, the views from the highest summit reach as far as the Isle of Man, the Wicklow Mountains in Ireland and the Lake District, as well as the entire sweep of Cardigan Bay. The view of Yr Eifl is especially striking from the SW coast of Anglesey, for instance from Ynys Llanddwyn. Ordnance Survey maps show a height of 564 metres, but a recent survey gives the height at 561 metres (1,841 feet).
