Gunung Kelud

Kelud

Stratovolkan · Indonesia · 1730 m

The broad, irregular summit of Kelud volcano contains several lava domes and a crater lake that has been the source of frequent violent and sometimes devastating eruptions. Construction of outlet tunnels following an eruption in 1919 that killed 5,110 people has reduced the number of fatalities from pyroclastic flows and lahars during subsequent eruptions.

Ringkasan geologi

The relatively inconspicuous Kelud stratovolcano contains a summit crater lake that has been the source of some of Indonesia's most deadly eruptions. A cluster of summit lava domes cut by numerous craters has given the summit a very irregular profile. Satellitic cones and lava domes are also located low on the E, W, and SSW flanks. Eruptive activity has in general migrated in a clockwise direction around the summit vent complex. More than 30 eruptions have been recorded since 1000 CE. The ejection of water from the crater lake during the typically short but violent eruptions has created pyroclastic flows and lahars that have caused widespread fatalities and destruction. After more than 5,000 people were killed during an eruption in 1919, an engineering project to drain the crater lake lowered the surface by more than 50 m. The 1951 eruption deepened the crater by 70 m, leaving 50 million cubic meters of water after the damaged drainage tunnels were repaired. Following more than 200 deaths in the 1966 eruption, a new deeper tunnel was constructed, and the lake's volume before the 1990 eruption was only about 1 million cubic meters.

Ringkasan Wikipedia

Gunung Kelud adalah sebuah gunung berapi di Jawa Timur yang hingga sekarang tergolong aktif. Gunung ini berada di perbatasan antara Kabupaten Kediri, Kabupaten Blitar, dan Kabupaten Malang. Lokasinya kira-kira 45 km sebelah timur pusat Kota Kediri dan 35 km sebelah utara pusat Kota Blitar. Gunung Kelud merupakan salah satu gunung berapi paling aktif di Indonesia. Sejak tahun 1000 M, Kelud telah meletus lebih dari 30 kali, dengan letusan terbesar berkekuatan 5 Volcanic Explosivity Index (VEI). Letusan terakhir Gunung Kelud terjadi pada tahun 2014.
