The 64th parallel in Iceland is a proof that Earth’s rotation has profound effect on topography, volcanism, geothermal and seismic activity of the globe. Here it is shown on a map in context with the division lines of convection rolls system:
In the western part, at the Reykjanes Peninsula we find a very interesting volcano, Thrihnukagigur, where you can enter a huge, emptied magma chamber. https://insidethevolcano.com/the-volcano/
Next comes Hveragerdi, with exceptional geothermal activity. https://www.south.is/en/what-to-see-do/nature/geothermal-area-in-hveragerdi
South Iceland Seismic Zone: Then the whole area from Hveragerði Town to Hekla Volcano is defined as the South Iceland Seismic Zone. https://www.jonfr.com/volcano/?p=745
Hekla Volcano marks the end of the SISZ, and the western side of the East Volcanic Zone. https://en.wikipedia.org/wiki/Hekla
Landmannalaugar is a popular hot spring area, within the most powerful high temperature area of Iceland, the Torfajökull Area. In between the two points of Hekla and Laki, the East Volcanic Zone is found. https://en.wikipedia.org/wiki/Landmannalaugar
Laki Volcano is located within a long fissure, and is associeted with the Laki eruption which started in 1783, so fiercely that it is thought to have changed the history of the whole world. The magma of the eruption did flow from the Grímsvötn volcanic site, but Laki is actually older than that. The lava appeared on the surface when it crossed the division line found there, as seen on the map above. Laki is close to the eastern border of the East Volcanic Zone. https://en.wikipedia.org/wiki/Laki
Öræfajökull Volcano is the highest in Iceland. It is located on crossings of lines of different convection rolls layers. The existence of this mountain can then be explained, but without the convection rolls model, it is extremely difficult to find a reason for its location. https://en.wikipedia.org/wiki/%C3%96r%C3%A6faj%C3%B6kull
To travel along the 64th parallel, and the surrounding areas is interesting, and the fact that the convection rolls are regularly arranged exactly at that latitude, in the middle of the intersection zone of equatorial and polar parts of the convection rolls system, makes it so diverse and powerful.
