1984-85 increased activity
An increase of the activity began on 13 September 1984 and peaked during the month and in early October, and remained at significantly higher levels than since 1972 until January 1985.
Previously, small Strombolian eruptions, which occurred 2-6 times/day, had occasionally ejected bombs from the 220-m-deep inner crater floor onto the main crater rim.
During the increased activity, bombs averaging 2 m long and reaching more than 10 m in length landed in all directions around the crater rim, and reached up to 1.2 km horizontal distance from the inner crater. The eruptions were witnessed from 60 km distance and the explosions could be heard from 2 km.

1984-1985 peningkatan aktivitas
Peningkatan aktivitas dimulai pada tanggal 13 September 1984 dan memuncak selama bulan dan pada awal Oktober, dan tetap pada tingkat yang jauh lebih tinggi dibandingkan sejak tahun 1972 sampai dengan Januari 1985.
Sebelumnya, letusan strombolian kecil, yang terjadi 2-6 kali / hari, kadang-kadang telah dikeluarkan bom dari lantai kawah dalam 220-m-jauh ke kawah utama.
Selama peningkatan aktivitas, bom rata-rata 2 m panjang dan mencapai lebih dari 10 m panjang mendarat di segala arah di sekitar bibir kawah, dan mencapai hingga 1,2 km jarak horizontal dari kawah bagian dalam. Letusan disaksikan dari 60 km jarak dan ledakan terdengar dari 2 km.
