Large amounts of pumice stone generated by the submarine volcanic eruption at Fukutoku Okanoba on 13 August 2021 drifted ashore, affecting ship navigation and fishery operations and posing challenges for disposal and a risk to benthic sea-life. As a new ...

This study discusses the influence of soil compaction on runoff generation with a special focus on forested Andosol sites. Because of their typical soil physical characteristics (low bulk density, high pore volumes) and the existent land use, these areas...

Stone Mastic Asphalt (SMA) mixtures are susceptible to drain down since they contain more bitumen comparing to Hot Mix Asphalt (HMA) mixtures. To prevent this problem, stabilizers are used in SMA mixtures. Stabilizers are costly materials and needed to b...

The Tungurahua volcano (Northern Andean Volcanic Zone) has been erupting since 1999, with at least
four eruptive phases up to present. Although a dozen of research focuses in tephra fall deposits during this period, none
of them cover the full eruptive c...

The Bruneau Woodpile site has long been popular among fossil collectors; however, the deposit has received scant attention from scientists. Our research reveals that the fossilized wood was deposited ca. 6.85 Ma, within the Chalk Hills Formation, and was...
