This was first recorded by the Roman historian Plutarch in the year AD 44-after Mt. Etna's eruption he observed the changing weather. In more recent years, volcanic winters have been observed after the eruptions of Pinatubo (1991, Indonesia), Krakatoa (1883, Indonesia), Tambora (1815, Indonesia), Laki (1783, Iceland), and Tarawera (1315, New Zealand).
