The Long Mynd is a heath and moorland plateau that forms part of the Shropshire Hills in Shropshire, England. The high ground, which is designated as an Area of Outstanding Natural Beauty, lies between the Stiperstones range to the west and the Stretton Hills and Wenlock Edge to the east. Much of it is owned and managed by the National Trust.
Pontesbury is a large village and civil parish in Shropshire and is approximately eight miles southwest of the county town of Shrewsbury. In the 2011 census, its population was 3,227. The village of Minsterley is just over a mile further southwest. The A488 road runs through the village, on its way from Shrewsbury to Bishop's Castle. The Rea Brook flows close by to the north with the village itself nestling on the northern edge of the Shropshire Hills AONB. Shropshire County Council in their current Place Plan detail the development strategy and refer to Pontesbury and neighbouring Minsterley as towns.
Shropshire's Geology is very diverse and most geological periods of time, and most rock types, can be found within the county. There is also a large amount of mineral wealth in the county, including lead, barytes, limestone, coal and iron, which helped the area develop the industrial revolution west of Clee Hill and, later, in the Ironbridge Gorge area. Quarrying is still active, with limestone for cement manufacture and concrete aggregate, sandstone, greywacke and dolerite for road aggregate, and sand and gravel for aggregate and drainage filters. Groundwater is an equally important economic resource.

The Myddfai Steep Belt is a geological structure which affects rocks of Silurian and Devonian age in mid Wales. It extends for tens of miles across country from near Carmarthen northeastwards via Mynydd Myddfai, Mynydd Bach Trecastell and Mynydd Epynt to the vicinity of Llangammarch Wells. Within this linear zone, the rock beds have been tilted steeply to the southeast. The folding took place in late Silurian to early Devonian times. This structure gives rise to a series of landscape features along its length, not least the steep northwest-facing scarps of the hills and ranges mentioned above. Indeed, the feature can be seen as a significant lineament in aerial and satellite views of Wales.
City is a hamlet in Powys, Wales.

The Longmyndian Supergroup is a 6,000-metre-thick (20,000 ft) sequence of Late Precambrian rocks that outcrop between the Pontesford–Linley Fault System and the Church Stretton Fault System in the Welsh Borderland Fault System. The supergroup consists of two major geological groups, the Stretton Group and the overlying Wentnor Group. The rocks are a generally regressive sequence from basinal facies to clastic sedimentation. The rocks are thought to be derived from Uriconian mountains that were formed during the southward subduction of an oceanic plate beneath a continental block. The rocks have since been folded due to fault movements and plunge gently to the south.
The Welsh Basin was a northeast-southwest aligned back-arc depositional basin during the Cambrian, Ordovician and Silurian periods during which a considerable thickness of marine sediments was laid down in the area. To the southeast lay the Midland Platform and to the northwest, within the Iapetus Ocean, through what is now Ireland and the Lake District, was an island arc; a northeast-southwest aligned Irish Sea landmass which was associated with volcanic activity. Examination of the sediments and associated fossils allows the deeper centre of the basin to be distinguished from shallower 'platform' areas along its southeastern margins. From the middle Silurian onwards, collision of Avalonia with the more northerly continent of Laurentia occurred giving rise to the Caledonian Orogeny. The inversion of the basin occurred at that time i.e. its uplift and deformation.
The 2019 Ridgecrest earthquakes of July 4 and 5, as well as a large aftershock on June 3, 2020, occurred north and northeast of the town of Ridgecrest, California and west of Searles Valley. They included three initial main shocks of magnitudes 6.4, 5.4, and 7.1, and many perceptible aftershocks, mainly within the area of the Naval Air Weapons Station China Lake. Eleven months later, a Mw 5.5 aftershock took place to the east of Ridgecrest. The first main shock occurred on July 4 at 10:33 a.m. PDT, approximately 18 km (11.2 mi) ENE of Ridgecrest, and 13 km (8.1 mi) WSW of Trona, on a previously unnoticed NE-SW trending fault where it intersects the NW-SE trending Little Lake Fault Zone. This quake was preceded by several smaller earthquakes, and was followed by more than 1,400 detected aftershocks. The M 5.4 and M 7.1 quakes struck on July 5 at 4:08 a.m. and 8:19 p.m. PDT approximately 10 km (6 miles) to the northwest. The latter, now considered the mainshock, was the most powerful earthquake to occur in the state in 20 years. Subsequent aftershocks extended approximately 50 km (~30 miles) along the Little Lake Fault Zone.
