Were there any major eruptions in the period June 1993 - June 1994?
Rodney Kuppen
Dear Rodney,
According to the Smithsonian Institution's Global Volcanism Network there
was activity at about 45 volcanoes during that period. Perhaps the
June 23, 1993, eruption of Unzen was most significant.
Pyroclastic flows
destroyed 187 homes and killed one person.
Kliuchevskoi
in Kamchatka, erupted explosively on July 15, 1993, sending ash to an altitude
of 4.9 miles (7.8 km). On April 18, 1994, Lascar, in northern Chile, had its
largest historical eruption, producing plinian columns 14 miles (22 km)
above the crater and light ash fall in Buenos Aires, 900 miles (1500 km)
to the southeast. There was continuous, or nearly continuous activity at
Stromboli (Italy), Arenal (Costa Rica),
Kilauea
(Hawaii), Veniaminof (Alaska),
Unzen
(Japan), Sakura-jima (Japan), and Manam (Papua, New
Guinea). In January of 1994, seismicity on the Juan de Fuca ridge was
interpreted as a possible eruption on the sea floor.
