Since then the catalogue has been and it was not until about 1860 that State-wide prospecting, steadily added to by staff members as new information at first for gold, was well underway. The early published has been obtained, and a similar card file was started for references to mineral discoveries are, in general, vague metallic minerals and their operations.

Robbins March, 2010 Alaska Division of Geological & Geophysical Surveys SHEET 3 OF 3 Active Volcanoes of the Kurile Islands Volcanoes with documented historical eruptions are shown with the year Kamchatka of the most recent eruptive activity. An “active volcano” is defined as 50°N meeting at least one of three criteria: (1) A historically documented Peninsula eruption, (2) current fumarolic activity, or (3) scientific dating of an eruption within the past 3,500 years. Where no year is given, the date of the last Sea of eruption is uncertain. Acknowledgment: Alaid 1981 x C.A. Neal, Alaska Volcano Observatory, special thanks for project concept, data and guidance.

  • Volcans Monde SI Dec2010
    GEOLOGICAL MAP OF THE WORLD AT 1: 25,000,000 SCALE, THIRD EDITION - Compilator: Philippe Bouysse, 2006 ACTIVE AND RECENT VOLCANOES This list of 1508 volcanoes is taken from data of the Global Volcanism Program run by the Smithsonian Institution (Washington, D.C., USA) and downloaded in April 2006 from the site www.volcano.si.edu/world/summary.cfm?sumpage=num. From the Smithsonian's list, 41 locations have been discarded due to a great deal of uncertainties, particularly as concerns doubtful submarine occurrences (mainly ship reports of the 19th and early 20th centuries). Also have been omitted submarine occurrences from the axes of "normal" oceanic accretionary ridges, i.e. not affected by hotspot activity. NOTES Volcano number: the numbering system was developped by the Catalog of Active Volcanoes of the World in the 1930s and followed on by the Smithsonian Institution, namely in the publication of T. Simkin & L.Siebert: Volcanoes of the World (1994). Name and Geographic situation: some complementary information has been provided concerning a more accurate geographic location of the volcano, e.g. in the case of smaller islands or due to political changes (as for Eritrea). Geographic coordinates: are listed in decimal parts of a degree. The position of volcano no. 104-10 (Tskhouk-Karckar, Armenia) was corrected (Lat. 39°.73 N instead of 35°.73 N). An asterisk (*) in column V.F. indicates the position of the center point of a broad volcanic field. Elevation: in meters, positive or negative for submarine volcanoes. Time frame (column T-FR): this is a Smithsonian' classification for the time of the volcano last known eruption: D1= 1964 or later D2= 1900 – 1963 D3= 1800 – 1899 D4= 1700 – 1799 D5= 1500 – 1699 D6= A.D.1 – 1499 D7= B.C.
