The urban municipality of the city of Angra do Heroísmo. Geological evidence points to the bay being formed by basaltic lavas, much eroded and covered by pyroclastic surges, tuffs of palagonite-like matter, material formed by the interaction of molten basalt and cold seawater, and consolidated volcanic ash ejected from vents during volcanic eruptions, all from the volcano that helped define ...
Neoeuxinian deposits are found in the Black Sea below −20 m (−66 ft) water depth in three layers. The upper layers correspond with the peak of the Khvalinian transgression, on the shelf shallow-water sands and coquina mixed with silty sands and brackish-water fauna, and inside the Black Sea Depression hydrotroilite silts. The middle layers ...
The lake is situated within the caldera of the Sete Cidades Massif, an ancient volcano built on various layers of ash, pyroclasts and trachyte and basaltic lavas.It is a stratovolcano constructed from alternating phases of explosive and effusive ejecta, from dominantly basaltic pre-caldera eruptions, a trachytic caldera-forming stage and a post-caldera stage consisting of alternating trachytic ...

The wave reached about 10 palms (about 150 m) and up to 80 palms (about 120 m). 1757 - Earthquake in São Jorge, 9 ...
The following day, 19 June, Sabrina Island had grown to an estimated altitude of 20 metres (66 ft) above sea level and measured approximately 1 kilometre (0.62 mi) in diameter. Despite being 5 kilometres (2.7 nmi; 3.1 mi) away from the island, Sabrina became covered in fine black ash and water thrown into the air by the eruption. The ship's ...
