This compilation shows thermal maps of Kīlauea summit collected on May 14 and 28, 2025. These maps followed episodes 21 and 23 of the ongoing Kīlauea summit eruption, respectively, and both show inactive but warm lava flows produced by the preceding lava fountaining episodes.

Introduction The bedrock geology of the Bellows Falls 7.5- x 15-minute quadrangle, Vermont and New Hampshire, consists of polydeformed Ordovician to Devonian metasedimentary, metavolcanic, and metaplutonic rocks of the Connecticut Valley trough, Bronson Hill anticlinorium (or Bronson Hill terrane), and the Central Maine terrane. Previous work in this area includes a 1:62,500-scale...
