New Paleointensity Data From Aniakchak Volcano, Alaska, USA

Abstract This study presents the first set of Holocene, high‐quality absolute paleointensity data from Alaska, USA. Existing for Holocene are generally located at mid‐northern latitudes in North America, Europe, Middle East, and eastern Asia. Relatively few Alaska region. IZZI‐modified experiments were conducted on glassy volcanic materials Aniakchak volcano, a mid‐ to high‐latitude composite volcano Alaska‐Aleutian arc. The CCRIT selection criteria applied results. A total 30 specimens six samples with estimated ages ranging 1931 CE 2,300 years before present passed all criteria. sample‐mean paleointensities ranged 49.5 68.0 microTesla (μT). results comparable modeled intensities, however except one lower than those predicted by geomagnetic field models. estimate historical eruption was about 15 μT greater expected strength. overestimate may result unrecognized alteration or non‐ideal remanence carriers this sample. Further evaluation using Bayesian estimation method resulted that encompasses strength within uncertainty. These new valuable contribution high‐northern latitude paleomagnetic set. Incorporation these into future models will improve predictions behavior
