There is another triple junction where the Eurasian Plate meets the Anatolian Sub-Plate and the Arabian Plate. The Anatolian Sub-Plate is currently being squeezed by the collision of the Eurasian Plate with the Arabian Plate in the East Anatolian Fault Zone.[5][6]
The boundary between the North American Plate and the Eurasian Plate in the area around Japan has been described as "shifty".
All volcanic eruptions in Iceland, such as the 1973 eruption of Eldfell, the 1783 eruption of Laki and the 2010 eruption of Eyjafjallajökull, are caused by the North American and the Eurasian plates moving apart, which is a result of divergent plate boundary forces.
The convergent boundary between the Eurasian Plate and the Indian Plate formed the Himalayas mountain range. The geodynamics of

The Anatolian tectonic block (sub-plate) is being affected by converging plate movements that occur between the Arabian-African and Eurasian plates (e.g. Armijo, Meyer, Hubert, & Barka, Citation1999; Bozkurt, Citation2001; Jackson & McKenzie, Citation1984; Le Pichon, Chamot-Rooke, Lallemant, Noomen, & Veis, Citation1995; McKenzie, Citation1972, 1978; Şengör, Citation1979, 1980; Sengör, Görür, & Saroglu, Citation1985; Taymaz, Jackson, & McKenzie, Citation1991). As a result of this collision, the North Anatolian (NAF) and East Anatolian (EAF) transform faults have been formed. The Anatolian sub-plate is bounded to the north and east by these faults. The impingement started to move the sub-plate westward and resulted compression and uplifts near the Karlıova triple junction in the Eastern Anatolia. As a result of anti-clockwise rotational movement of the Anatolian sub-plate in a westward direction four different neotectonic regions have been formed namely: (1) East Anatolian compressional region, (2) North Anatolian region, (3) Central Anatolian 'ova' region and (4) West Anatolian extensional region (Sengör et al., Citation1985).

Hence, the problem: geodetic models imply a plate boundary between Japan and Eurasia, but published geological and seismological evidence does not support placing it in the Japan Sea or at the ISTL. If, as studies show, almost half of the convergence between North America and Eurasia is taken up in Hokkaido and across N Japan, the small amount of remaining convergence may be difficult to distinguish given the large elastic response in the upper plate (N Honshu) after the 2011 Tohoku-oki (M9.0) earthquake, and strong coupling at the megathrust. To draw such a plate boundary on tectonic maps implies a degree of certainty about its location which is unfounded
