Storfjorden (Sunnmøre)

Storfjorden or Storfjord is a 110 km long fjord in the Sunnmøre region of Møre og Romsdal county, Norway. It stretches from the village of Hareid in the west to the villages of Tafjord and Geiranger in the east. The Storfjorden system branches off into several smaller fjords including the famous Geirangerfjord and Tafjorden. At the village of Stranda, the main fjord branches off into the Sunnylvsfjorden-Geirangerfjorden to the west and the Norddalsfjorden-Tafjorden to the east.

The name literally means the "big" or "great" fjord, indicating that this is a long fjord and it is, in fact, the main fjord in this region. Stretching about 110 km, Storfjord is the 5th longest fjord in Norway. The Storfjord is a dominant topographical feature in the Sunnmøre region as it cuts the region in two parts that are only connected by ferry. The deepest point in the fjord is 679 m near the village of Dyrkorn in the municipality of Stordal.

The landscape around Storfjorden is typical for Western Norway. The mouth of the fjord is surrounded by islands with mountains reaching 500 to 800 m above sea level. Further to the east there are higher mountains. At the villages of Tafjord and Geiranger, the mountains climb to about 1500 to 1800 m above sea level. Most of the Storfjorden has characteristically steep or very steep shores, interrupted by several gentle valleys stretching up to 30 km into the hinterland. In this way, the Storfjorden system is, along with the Nordfjorden, Sognefjorden, and Hardangerfjorden fjord-systems, the major samples of the typical west coast fjords highly praised by visitors.

On the steep shores of the fjord, there are several historic mountain farms such as Ytste Skotet in Stordal and Me-Åkernes, Skageflå, and Knivsflå in Stranda.

Transportation
Several car ferries cross the fjord, but there are no bridges or tunnels. The proposed Storfjord Bridge may one day cross the fjord, but it is cost prohibitive at this time. Here is a list of the ferry crossings:
 * Hareid-Sulesund from Hareidlandet in the municipality of Hareid to Sula island in Sula across the Sulafjorden
 * Leirvågen-Festøya-Hundeidvik (a 3-point ferry crossing) from Leirvågen on Sula island across the Storfjorden to Festøya in Ørsta then on to Hundeidvik across the Hjørundfjorden in Sykkylven
 * Leknes-Sæbø across the Hjørundfjorden
 * Ørsneset-Magerholm from Ørsneset in Sykkylven to Magerholm in Ålesund, part of Norwegian County Road 60
 * Stranda-Liabygda from the village of Stranda in the west to Liabygda in the east, Norwegian County Road 650
 * Eidsdal-Linge across the Norddalsfjorden, part of Norwegian County Road 63
 * Geiranger-Hellesylt a tourist route along the Geirangerfjord, only operates in the summer

Due to the steep slopes along the shores, road construction is challenging and overland road transport is often limited to valleys. On the northern shore of the Storfjorden, there a continuous network of roads from Tafjord to the island of Sula using the roads 63, 650, E39, 656, 60 and 61. On the southern shore, there are only short sections of roads along the fjord itself.

During summer the Hurtigruten line visits the Storfjorden and Geirangerfjorden regularly.

Landslide and megatsunami
At 10:00 p.m. on 8 January 1731, a landslide with an estimated volume of 6,000,000 m3 fell from a height of 500 m on the slope of the mountain Skafjell into the Storfjorden opposite Stranda. The slide generated a megatsunami 30 m in height that struck Stranda, flooding the area for 100 m inland and destroying the church and all but two boathouses, as well as many boats. Damaging waves struck as far as way as Ørskog. The waves killed 17 people. It was the first natural disaster in Norway to be reported and documented in historic time.
