Fields of dislodged boulders and blocks record catastrophic coastal floodingduring strong storms or tsunamis and play a pivotal role in coastal hazardassessment. Along the rocky carbonate coast of Eastern Samar (Philippines)we documented longshore transport of a block of 180 t and boulders (up to23.5 t) shifted upslope to elevations of up to 10 m above mean lower lowwater level during Supertyphoon Haiyan on 8 November 2013. Initiation-of-motionapproaches indicate that boulder dislocation occurred with flow velocitiesof 8.9–9.6 m s<sup>−1</sup>, which significantly exceeds depth-averaged flow velocitiesof a local coupled hydrodynamic and wave model (Delft3D) of the typhoon witha maximum < 1.5 m s<sup>−1</sup>. These results, in combination with recentlypublished phase-resolving wave models, support the hypothesis thatinfragravity waves induced by the typhoon were responsible for theremarkable flooding pattern in Eastern Samar, which are not resolved inphase-averaged storm surge models. Our findings show that tsunamis andhydrodynamic conditions induced by tropical cyclones may shift boulders ofsimilar size and, therefore, demand a careful re-evaluation of storm-relatedtransport where it, based on the boulder's sheer size, has previously beenascribed to tsunamis
