Numerical and experimental analysis of Wetumpka impact crater, Alabama.
(2021-07-19)
Impacts are the most crucial process in the formation of the solar system, since planets and other bodies are considered to have formed by accretion of small objects through collisional processes. By studying craters on ...
Paleoseismic Investigation of the Relationship of Earthquake-Induced Liquefaction Deposits to Deformation at a Site in the New Madrid Seismic Zone
(2021-07-28)
Geophysical, geologic, and soil surveys were conducted at a site in the New Madrid seismic zone (NMSZ) to explore the relationship of fluvial sedimentary deposits to earthquake-induced liquefaction features, such as sand ...
Perception and application of climate science by distinct audiences: Impacts of measurement, attention, and credibility
(2022-08-03)
Climate change is among the greatest threats to human lives and livelihoods and any efforts to reduce harm by mitigating climate change or adapting to changes will require mass participation. However, the knowledge and ...
