The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Kelud volcano (also spelled Kelut) is one of East Java's most active volcanoes. The volcano has a spectacular large crater that contains a lake, which was a popular weekend destination but also the origin of devastating mud flows (lahars). In Oct-Nov 2007, a new lava dome grew within the lake to form an island, replacing most of the water.
Kelut is notorious among Indonesia's volcanoes for its violent, and often deadly explosive eruptions. One of the worst volcanic disasters occurred during the 1919 eruption, when the (then very large) crater lake drained and formed lahars that killed at least 5160 people. An eruption in 1586 is believed to have caused even more than 10,000 fatalities.
Stratovolcano 1731 m (5,679 ft) East Java, Indonesia, -7.93°S / 112.31°E Current status: dormant (1 out of 5) Kelud webcams / live data Kelud volcano books | Tours Kelud volcano eruptions: 1500(?), 1548, 1586 ((sub-)Plinian eruption?), 1641 (sub-Plininan eruption?), 1716, 1752, 1756(?), 1771, 1776, 1785, 1811, 1825, 1826, 1835, 1848, 1849(?), 1864, 1901, 1919, 1920, 1951, 1966, 1967, 1990, Oct-Nov 2007, 13 Feb 2014 Typical eruption style: Explosive. Lava domes, pyroclastic flows. Presence of extensive crater lake at low elevation, generating destructive lahars. Last earthquakes nearby
The alert level of the volcano was raised today from 1 ("normal") to 2 ("Waspada", "watch") on a scale of 1-4. During the second half of 2014, a strong increase in seismic activity and a 5.5 deg temperature increase of the crater lake water had been detected.
The number of shallow volcanic earthquakes rose from averages of 1-2 per day to approx 10 per day during 20-31 Jan and climbed to more than 100 events since the start of February alone. This might indicate a shallow intrusion is taking place and could lead to a new eruption. VSI recommends not to approach the crater within 2 km radius.
The last eruption of Kelut was in Oct-Nov 2007, when a new lava dome grew within the crater lake.
CVGHM lowered the Alert Status of Kelut on 8 November from 4 to 3 (on a scale of 1-4), due to a decrease in seismicity and deformation. Temperatures of the crater lake were measured at 75 deg C on 6 Nov, and 150-210 deg C on the surface of the new lava dome. According to a local news article, a volcanologist reported that the lava dome was 250 m in diameter and 120 m above the crater lake surface. On 11 November, a plume rose to an altitude of 3.7 km (12,000 ft) a.s.l. and ashfall was reported in several areas. CVGHM recommended that evacuees could return to their homes, but should stay clear of the mountain within a 3-km radius was restricted.[more]
The Center of Volcanology and Geological Hazard Mitigation (CVGHM) raised the altert status of Kelut volcano on 16 October from 3 to 4 (on a scale of 1-4). During 15-28 September, gas discharge from the crater lake increased and spread in a radius of 5 m. Inflation around the summit occurred during 13-16 October. On 16 October, the temperature in the crater lake increased to 37.8 degrees C.
Ijen volcano photos: Ijen volcano in East Java is famous for its turquoise acid crater lake and the large sulfur deposits that are being mined by local workers. At night, the scene is illuminated by ghostly blue flames, as sulfur ignites.
