Tuk-Tuk, a small peninsula on Samosir Island, provides a vista of Latung Strait, which separates the opposing resurgent blocks of Samosir (right) and the Uluan block on the left. The Latung Strait marks the center of post-caldera resurgence, which tilted the Uluan block, located within the SE part of the caldera, to the SE and the Samosir Island block to the NE.
