Some of the land of Beltring Hundred survived the flood, however, and became the Hallig of Nordstrandischmoor as well as the site of the modern municipality of Ockholm.
Rungholt was situated on the island of Strand, which was rent asunder by another storm tide in 1634, and of which the islets of Pellworm, Nordstrand and Nordstrandischmoor are the only remaining fragments.
