JUNE EIGHTH 1995

THE TWO HUNDRED AND SECOND BIRTHDAY OF THE OUTBREAK ON THE LAKI FISSURE, ICELAND

Born June 8, 1783

Called by Icelanders the Skaftár fires. The lava outpourings lasted until 7 Feb. 7, 1784. In all 14 cubic kilometers of lava were erupted along a chain of over 140 craters 27 km long called Lakagiger and later a neighboring fissure as well. The effects of the eruption, smog, colder weather, loss of farm land and a famine in Iceland were severe. These events were said to have caused the death of one quarter of the population of Iceland!. There was at least a week of precursory seimic activity. An account by a local cleric, Jon Steingrimsson, is reprinted by Krafft. A map is included in a description in Francis, (p.140)

Born June 14, 1995. Hasn't had its first birthday yet.

THE FIFTY-FIRST BIRTHDAY OF SHOWA-SHINZAN DOME, JAPAN

Born June 23, 1944

The dome is associated with the magma chamber of the large nearby volcano Usu. The dome was 110 m above the sedimentary cover.

Quakes began in Dec. 1943 . Ground upheaval occurred before eruption. Smoke first issued from a fissure June 23rd. Eruption continued til Sept.1945. The date of birth might be considered to be the beginning of November 1944, when a column of solidfied magma began to rise from the center of the ring fissure.in the sedimentary cover. June 23, the date used here, is the date given in volcanoes of the World. The dome outline at several stages of growth was recorded by the postmaster on his dirty wIndow overlooking the dome. Such outlines have been called Mimatsu diagrams named after the postmaster

THE SEVENTY-THIRD BIRTHDAY OF THE SANTIAGUITO DOME, GUATEMALA

Born June 22, 1922

The dome grew in the crater of the 1902 eruption of Santa María. Coalescing domes subsequently grew in a line to the west, well beyond the confines of the crater. .This volcano is therefore very marginally eligible for inclusion as a "new volcano"
