| Abstract: | This paper describes the results of investigations of the consequences of the storms on the Pacific coast of Shikotan Island
that occurred on October 7–10, 2006 and January 6–8, 2007. These storms and their impact on the coastal zone can be considered
as extreme events for the last 40–50 years. The heights and flooding area of the storm surges within bay coasts of different
types were measured. The coastal relief’s changes are described. During the storms, a cover of deposits was formed having
a size of up to 30 m outside the beach zone and up to 52 m in the near-mouth zones. The grain-size composition of the storm
deposits is analyzed and their difference from other coastal facies, including tsunami sands, are established. |
