| Lord Howe Island (/haxcax8a/; formerly Lord Howe's Island) is an irregularly crescent-shaped volcanic remnant in the Tasman Sea between Australia and New Zealand, 600xc2xa0km (320xc2xa0nmi) directly east of mainland Port Macquarie, 780xc2xa0km (420xc2xa0nmi) northeast of Sydney, and about 900xc2xa0km (490xc2xa0nmi) southwest of Norfolk Island. | WIKI |
| Apart from Lord Howe Island itself, the most notable of these is the volcanic and uninhabited Ball's Pyramid about 23xc2xa0km (14xc2xa0mi; 12xc2xa0nmi) to the southeast of Howe. | WIKI |
| Other diving sites are found off Ball's Pyramid, 26xc2xa0km (16xc2xa0mi) away, where trenches, caves, and volcanic drop-offs occur. | WIKI |
| Lord Howe Island is an irregularly crescent-shaped volcanic remnant in the southwest Pacific Ocean. | WIKI |
| Both the north and south sections of the island are high ground of relatively untouched forest, in the south comprising two volcanic mountains, Mount Lidgbird (777xc2xa0m (2,549xc2xa0ft)) and Mount Gower which, rising to 875xc2xa0m (2,871xc2xa0ft), is the highest point on the island. | WIKI |
| This chain of nine volcanic peaks was probably produced by the northward movement of the Indo-Australian Plate over a stationary hotspot, so the oldest guyots were the first formed and most northerly as the plate moved northward at a rate of 6xc2xa0cm (2.4xc2xa0in) per year (see plate tectonics). | WIKI |
| Volcanic breccia on Mount Lidgbird beach | WIKI |
| Two periods of volcanic activity produced the major features of the island. | WIKI |
| The first about 6.9 million years (Mya) ago produced the northern and central hills, while the younger and highly eroded Mount Gower and Mount Lidgbird were produced about 6.3 Mya by successive basalt (an extrusive igneous rock) lava flows that once filled a large volcanic caldera (crater)[102] and can now be seen as horizontal basalt strata on mountain cliffs (at Malabar and Mount Gower) occasionally interspersed with dikes (vertical lava intrusions). | WIKI |
| [103][104] Geological pyroclastic remnants of volcanic eruption can be seen on the 15xc2xa0ha (37-acre) Roach Island (where the oldest rocks occur) and Boat Harbour as tuff (ash), breccia (with angular blocks), and agglomerate (rounded 'bombs'). | WIKI |
| The Lord Howe Island Group is an outstanding example of oceanic islands of volcanic origin containing a unique biota of plants and animals, as well as the worldxe2x80x99s most southerly true coral reef. | UNESCO |
| It is considered to be an outstanding example of an island system developed from submarine volcanic activity and demonstrates the nearly complete stage in the destruction of a large shield volcano. | UNESCO |
