    THE FORTIETH BIRTHDAY OF CONES 4 and 5 TULUMAN, VOLCANO, PAPUA NEW GUINEA

    Born February 11, 1955, in the North Bismark Sea. Cones Four and Five,the first surface outbreaks at two of the six sites from which igneous products were emitted, collectively called the volcano Tuluman. In the period 1953-1957 the submarine activity gave rise to two islands Of the eight sites of submarine activity all but Cones 1 and 6 gave rise to land above sealevel. Between 1954-1957 six cones (designated Cones 2,3,4,5,7A,7B) appeared at one or another time above sea level in this area. The birthdays of all these cones have been recorded.here. There are some who would catagorize all the cone eruptions as being part of a single volcanic eruption. All emitted solid or liquid igneous material above sea level; are not at the same site as, or on the flanks of a subaerial volcano. These attributes qualify them as being "New Volcanoes"

    THE FIFTY SECOND BIRTHDAY OF PARÍCUTIN VOLCANO, MEXICO

    Born Feb. 20, 1943, Parícutin is now 424 meters above the surroundings. There are no recorded eruptions since the period of activity 1943-March,4,1952 During this period the volcano was closely and continually monitored, chiefly by scientists of the U S Geological Survey. Among the geologists monitoring and studying the volcano were the Mexican gelogist, Dr.Esequiel Ordó:ñez and Gutiérrez, Foshag,Wilcox, Segerstrom and Fries of the U.S. Geological Survey. Information about these geologists is included in the Paríutin monograph of Luhr and Simkin. Fumarole tempertures at the Ahuan vent in November1985 were as high as 473 degrees C., higher than the last time mesasured in April 1983 and had declined to in 1976 The event was witnessed by the owner of the farm, Dionisio Pulido. He described seeing a hole in the ground, the ground rising 2 or 21/2 meters and ash coming from the crack. Foshag, usgs bull and Segerstrom

    Born Feb. 23,1770. Some have said 1769, but it is unlikely.

    Now 1965 m above the surroundings. There were strong earthquakes at the end of 1769. Last eruption Oct. 30, 1966
