Mount Garibaldi: hazard potential from a long-dormant volcanic system in the Pacific Northwest

A lava flow simulation model for the development of volcanic hazard maps for Mount Etna (Italy)

Volcanic hazard assessment is of paramount importance for the safeguard of the resources exposed to volcanic hazards. In the paper we present ELFM, a lava flow simulation model for the evaluation of the lava flow hazard on Mount Etna (Sicily, Italy), the most important active volcano in Europe. The major contributions of the paper are: (a) a detailed specification of the lava flow simulation mo...

Long-term volcanic hazard assessment on El Hierro (Canary Islands)

Long-term hazard assessment, one of the bastions of risk-mitigation programs, is required for land-use planning and for developing emergency plans. To ensure quality and representative results, long-term volcanic hazard assessment requires several sequential steps to be completed, which include the compilation of geological and volcanological information, the characterisation of past eruptions,...

Starlings in the Pacific Northwest

Petrogenesis of volcanic rocks from Razei region in Northwest Ardabil, Iran

The Razei region in the northwest of Ardabil is considered a part of West Alborz-Azerbaijan. Rocks in this area were created by Eocene volcanic activities. These rocks range from andesite to olivine basalt. The common texture of these rocks is Porphyritic with microlithic matrix. The phenocrysts of these rocks are often clinopyroxene, plagioclase, and olivine. The texture is made of microlithic...

Identification of Beijerinckia from Pacific Northwest soils.

The genus Beijerinckia Derx has been described as being limited to the tropical regions and rare or nonexistent in temperate zones (M. Alexander, Introduction to Microbiology, 1961). Other workers (J. Dobereiner and A. P. Ruschel, Soil Biol. Intern. News Bull. 1:3, 1964) have expressed surprise that Beijerinckia has not been reported as found in soils in such large areas as the southern United ...
