context_page_description: Rissa is a former municipality in the old Sør-Trøndelag county in Norway in the Fosen region. The municipality existed from 1860 until its dissolution on 1 January 2018 when it became part of the municipality of Indre Fosen in Trøndelag county. The administrative centre of the municipality was the village of Årnset. Other villages in the municipality included Askjem, Hasselvika, Husbysjøen, Rørvika, Råkvåg, and Stadsbygd.
  The 621-square-kilometre municipality was the 179th largest by area out of the then 426 municipalities in Norway. Rissa was the 158th most populous municipality in Norway with a population of 6,628. The municipality's population density was 11.3 inhabitants per square kilometre and its population had increased by 4.1% over the last decade.
context_section_description: In April 1978, Rissa was home to a quick-clay landslide which encompassed an area of 330,000 square metres (3,600,000 sq ft) and sent 6,000,000 cubic metres (7,800,000 cu yd) of clay from the Årnset area  on the shore into Botn, causing a miniature tsunami on the north shore in Leira.  This slide is particularly famous because a large portion of the slide happened to be recorded on film by two amateur photographers.
