Reversals and excursions of Earth's geomagnetic field create marker horizons that are
readily detected in sedimentary and volcanic rocks worldwide. An accurate and precise …

Geophysical imaging of a tilted mantle plume extending at least 500 km beneath the
Yellowstone caldera provides compelling support for a plume origin of the entire …

Plate motions relative to the hotspots over the past 4 to 7 Myr are investigated with a goal of
determining the shortest time interval over which reliable volcanic propagation rates and …

The available data, mainly topography, geoid, and heat flow, describing hotspots worldwide
are examined to constrain the mechanisms for swell uplift and to obtain fluxes and excess …

The superlative hot springs, geysers, and fumarole fields of Yellowstone National Park are
vivid reminders of a recent volcanic past. Volcanism on an immense scale largely shaped …

In this release of hazard maps we present numerous maps and data with varying
parameters. The computations for these maps and data used 50 year return periods on firm …

Integration of geophysical and geological data show that the Yellowstone hotspot resulted
from a mantle plume interacting with the overriding North America plate, a process that has …

The accommodation of large strains in the upper crust is largely achieved by the
accumulation of displacement on faults. Observation shows that as a fault accumulates …

The Wasatch fault zone (WFZ) forms the eastern boundary of the Basin and Range province
and is the longest continuous, active normal fault (343 km) in the United States. It underlies …

Four maps are presented here that show the location and extent of magmatic fields between
eastern Alaska and northern Mexico during the successive time intervals of 55–40, 40–25 …
