Aegean Sea Plate

The Aegean Sea Plate (also called the Hellenic Plate or Aegean Plate) is a small tectonic plate located in the eastern Mediterranean Sea under southern Greece and far western Turkey. Its southern edge is a subduction zone south of Crete, where the African Plate is being swept under the Aegean Sea Plate.[1] To the north is the Eurasian Plate, which is a divergent boundary responsible for the formation of the Gulf of Corinth.

1810 Crete earthquake

The 1810 Crete earthquake occurred at 22:15 on 16 February. It caused great destruction in Heraklion, some damage from Malta to northern Egypt and was felt from central Italy to Syria. 2,000 fatalities were reported from Candia (Heraklion).

1881 Chios earthquake

The 1881 Chios earthquake occurred at 13:40 local time (11:30 UTC) on 3 April. It caused severe damage on the island of Chios and also affected Çeşme and Alaçatı on the coast of Turkey. The earthquake had an estimated magnitude of 7.3 and there were an estimated 7,866 casualties. The devastation from the earthquake was the last of the three 'catastrophes' that affected the island of Chios in the 19th century.

1932 Ierissos earthquake

The 1932 Ierissos earthquake occurred at 19:20 on 26 September. It caused severe damage in Ierissos and the surrounding part of the Chalkidiki peninsula, with 491 casualties reported.

Adriatic Plate

The Adriatic or Apulian Plate is a small tectonic plate carrying primarily continental crust that broke away from the African plate along a large transform fault in the Cretaceous period. The name Adriatic Plate is usually used when referring to the northern part of the plate. This part of the plate was deformed during the Alpine orogeny, when the Adriatic/Apulian Plate collided with the Eurasian plate.

The Adriatic/Apulian Plate is thought to still move independently of the Eurasian Plate in NNE direction with a small component of counter-clockwise rotation. The fault zone that separates the two is the Periadriatic Seam that runs through the Alps. Studies indicate that in addition to deforming, the Eurasian continental crust has actually subducted to some extent below the Adriatic/Apulian Plate, an unusual circumstance in plate tectonics. Oceanic crust of the African Plate is also subducting under the Adriatic/Apulian Plate off the western and southern coasts of the Italian Peninsula, creating a berm of assorted debris which rises from the seafloor and continues onshore. This subduction is also responsible for the volcanics of southern Italy.

The eastern Italian Peninsula, the coastal part of Slovenia, Istria, Malta and the Adriatic Sea are on the Adriatic/Apulian Plate. Mesozoic sedimentary rocks deposited on the plate include the limestones that form the Southern Calcareous Alps.

African Plate

The African Plate is a major tectonic plate straddling the equator as well as the prime meridian. It includes much of the continent of Africa, as well as oceanic crust which lies between the continent and various surrounding ocean ridges. Between 60 million years ago and 10 million years ago, the Somali Plate began rifting from the African Plate along the East African Rift. Since the continent of Africa consists of crust from both the African and the Somali plates, some literature refers to the African Plate as the Nubian Plate to distinguish it from the continent as a whole.

Armorican terrane

The Armorican terrane, Armorican terrane assemblage, or simply Armorica, was a microcontinent or group of continental fragments that rifted away from Gondwana towards the end of the Silurian and collided with Laurussia towards the end of the Carboniferous during the Variscan orogeny. The name is taken from Armorica, the Gaulish name for a large part of northwestern France that includes Brittany, as this matches closely to the present location of the rock units that form the main part of this terrane.

Baltic Plate

The Baltic Plate was an ancient tectonic plate that existed from the Cambrian Period to the Carboniferous Period. The Baltic Plate collided against Siberia, to form the Ural Mountains about 280 million years ago. The Baltic Plate, however, fused onto the Eurasian Plate when the Baltic Plate collided against Siberia when the Ural Mountains were completely formed. The Baltic Plate contained Baltica and the Baltic Shield which is now located in Norway, Sweden and Finland.

Ebro Basin

The Ebro Basin was a foreland basin that formed to the south of the Pyrenees during the Paleogene. It was also limited to the southeast by the Catalan Coastal Ranges. It began as a fully marine basin with connections to both the Atlantic Ocean and the Mediterranean Sea, before becoming an endorheic basin during the Late Eocene. In the Miocene the basin was captured by a precursor to the Ebro river and the new drainage system that developed eroded away much of the basin fill, except for resistant lithologies, such as the conglomerates at Montserrat.

Geology of Andorra

Andorra is located in the Axial Zone of the central Pyrenees mountain range in south western Europe, which means that it has intensely folded and thrusted rocks formed when the Iberian peninsula was rotated onto the European continent.

Geology of Svalbard

The geology of Svalbard encompasses the geological description of rock types found in Svalbard, and the associated tectonics and sedimentological history of soils and rocks. The geological exploration of Svalbard is an ongoing activity, and recent understandings may differ from earlier interpretations.

Gothian orogeny

The Gothian orogeny (Swedish: Gotiska orogenesen) or Kongsberg orogeny was an orogeny in western Fennoscandia that occurred between 1750 and 1500 million years ago. It precedes the younger Sveconorwegian orogeny that has overprinted much of it. The Gothian orogeny formed along a subduction zone and resulted in the formation of calc-alkaline igneous rocks 1700 to 1550 million years ago, including some of the younger members of the Transscandinavian Igneous Belt.The deformation associated with the orogeny can be seen in metatonalite, paragneiss and biotite orthogneisses in southeast Norway. These rocks were all subject to amphibolite facies metamorphism.

Hallandian-Danopolonian event

The Hallandian-Danopolonian event was an orogeny and thermal event that affected Baltica in the Mesoproterozoic. The event metamorphosed pre-existing rocks and generated magmas that crystallized into granite. The Hallandian-Danopolonian event has been suggested to be responsible for forming an east-west alignment of sedimentary basins hosting Jotnian sediments spanning from eastern Norway, to Lake Ladoga in Russia. The alignment of subsidence is thought to correspond to an ancient back-arc basin parallel to a subduction zone further south.

Hellenic arc

The Hellenic arc or Aegean arc is an arcuate tectonic feature of the eastern Mediterranean Sea related to the subduction of the African Plate beneath the Aegean Sea Plate. It consists of an oceanic trench, the Hellenic Trench, on its outer side; two arcs—a non-volcanic outer arc and an inner volcanic arc, the South Aegean Volcanic Arc; and a marginal sea on its inner side.

Island arc

Island arcs are long chains of active volcanoes with intense seismic activity found along convergent tectonic plate boundaries (such as the Ring of Fire). Most island arcs originate on oceanic crust and have resulted from the descent of the lithosphere into the mantle along the subduction zone. They are the principal way by which continental growth is achieved.

Island arcs can either be active or inactive based on their seismicity and presence of volcanoes. Active arcs are ridges of recent volcanoes with an associated deep seismic zone. They also possess a distinct curved form, a chain of active or recently extinct volcanoes, a deep-sea trench, and a large negative Bouguer anomaly on the convex side of the volcanic arc. The small positive gravity anomaly associated with volcanic arcs has been interpreted by many authors as due to the presence of dense volcanic rocks beneath the arc. While inactive arcs are a chain of islands which contains older volcanic and volcaniclastic rocks.The curved shape of many volcanic chains and the angle of the descending lithosphere are related. If the oceanic part of the plate is represented by the ocean floor on the convex side of the arc, and if the zone of flexing occurs beneath the submarine trench, then the deflected part of the plate coincides approximately with the Benioff zone beneath most arcs.

Mezen Basin

The Mezen Basin is a sedimentary basin located in northwestern Russia. It list southeast of the White Sea and bounds the Timanide Orogen to the north and west. The basin is classified as a pericratonic and epicratonic foreland basin within the East European Craton. The Mezen Basin contains the following pre-Vendian sediments: the Ust-Nafta Group with a maximum thickness of 1200 meters, on top of this is rests the Safonovo Group made up of carbonates and siliciclastic sediments reminiscent of flysch. The Safonovo Group upward end is a unconformity that separates it from the poorly sorted sandstones of the Uftuga Formation.


The Taygetus, Taugetus, Taygetos or Taÿgetus (Greek: Ταΰγετος, romanized: Taygetos) is a mountain range in the Peloponnese peninsula in Southern Greece. The highest mountain of the range is Mount Taygetus, also known as the "Profitis Ilias", or "Prophet Elias". The name is one of the oldest recorded in Europe, appearing in the Odyssey. In classical mythology, it was associated with the nymph Taygete. During Byzantine times and up until the 19th century, the mountain was also known as Pentadaktylos (Πενταδάκτυλος; Greek for five-fingered, a common name during that period).

Tisza Plate

The Tisza Plate is a tectonic block, or microplate, in present-day Europe. The two major crustal blocks of the Pannonian Basin, Pelso and Tisza, underwent a complex process of rotation and extension of variable magnitude during the Cenozoic era. The northward push of the Adriatic Block initiated the eastward displacement and rotation of both the Alcapa (or Pelso) and Tisza blocks. The Zágráb-Hernád line is the former plate margin between the Pelso of African origin and the Tisza Plate of Eurasian origin.


Volgo–Uralia is a crustal segment that together with the Sarmatian Craton and the Fennoscandian Craton makes up the East European Craton. Volgo–Uralia is the easternmost of the three segments and borders the Sarmatian Craton to the southwest along the Pachelma aulacogen and the Fennoscandian Craton to the northwest along the Volhyn–Central Russian aulacogen.
