Geological Summary

As described by the Alaska Volcano Observatory, the Maclaren River Volcanic Field was first recognized by Brueske et al. (2023) and has been further characterized by Bearden (2023). The field, located east of the Maclaren River on either side of the Denali Highway, includes at least three monogenetic volcanoes that date from the last million years. The three identified features lie along a ~20 mile, NNE-SSW line that approximately traces the position of a tear in the Yakutat plate currently subducting under south-central Alaska. The field occurs in an area informally called “the Denali gap,” between the Aleutian and Wrangell arc volcanoes, where only minor volcanism has been identified (see also Buzzard Creek and Jumbo Dome). The lavas from the three cones are basaltic to basaltic andesitic in composition.

Eruptive History

The Global Volcanism Program is not aware of any Holocene eruptions from Maclaren River Volcanic Field. If this volcano has had large eruptions (VEI >= 4) prior to 12,000 years ago, information might be found on the Maclaren River Volcanic Field page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

WOVOdat
   Single Volcano View
   Temporal Evolution of Unrest
   Side by Side Volcanoes

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

GVMID Data on Volcano Monitoring Infrastructure The Global Volcano Monitoring Infrastructure Database GVMID, is aimed at documenting and improving capabilities of volcano monitoring from the ground and space. GVMID should provide a snapshot and baseline view of the techniques and instrumentation that are in place at various volcanoes, which can be use by volcano observatories as reference to setup new monitoring system or improving networks at a specific volcano. These data will allow identification of what monitoring gaps exist, which can be then targeted by remote sensing infrastructure and future instrument deployments.

Incorporated Research Institutions for Seismology (IRIS) Data Services map showing the location of seismic stations from all available networks (permanent or temporary) within a radius of 0.18° (about 20 km at mid-latitudes) from the given location of Maclaren River Volcanic Field. Users can customize a variety of filters and options in the left panel. Note that if there are no stations are known the map will default to show the entire world with a "No data matched request" error notice.
