    "descript": "The 14 January 2022 eruption of Tonga Hunga-Tonga Ha'apai volcano generated tsunamis that impacted the west coast of the United States on the morning of 15 January 2022. This data release presents runup heights and tsunami heights collected by the U.S. Geological Survey (USGS) and the California Geological Survey (CGS) during surveys at the Santa Cruz Harbor and beaches in Santa Cruz County, California, on January 19th and 20th, 2022 (USGS Field Activity 2022-607-FA). Evidence of tsunami inundation included high water marks on buildings and harbor infrastructure, wrack lines, and flow-direction indicators such as bent vegetation. Elevations surveyed at the maximum inland extent of tsunami inundation are classified as \u201crunup heights.\u201d High-water mark elevations are classified as \u201ctsunami heights.\u201d At Seabright, Beer Can, and Manresa beaches, the inferred tsunami inundation limit was identified as the highest wrack line on each beach. The wrack line coincided with a change in sand color, with the inundated side consisting of darker colored sand. Based on eyewitness and video observations of the tsunami in Santa Cruz Harbor, most of the surveyed tsunami and runup heights are the result of inundation from the highest wave around 08:50 PST (16:50 GMT). Flow-depth markers on buildings and infrastructure from a later wave were measured and reported as lower tsunami heights and are noted. The   final point data are provided in a comma-separated text file and are projected in cartesian coordinates using the Universal Transverse Mercator (UTM), Zone 10 North, meters coordinate system.",
