Relation of Recent Seismicity (1988-Present) to the 1958 Huslia, Alaska Earthquake Sequence
We have examined how recent seismicity in the Huslia region of central Alaska is related to active faults and the 1958 earthquake sequence (with at least 3 events of magnitude >6). Most of this region is swampy lowland dominated by alluvial material deposited by the Koyukuk River, making surficia...
