Last eruption February 2014

Kelud (Klut, Cloot, Kloet, Kloete, Keloed or Kelut) is an active stratovolcano located in East Java, Indonesia. Like many Indonesian volcanoes and others on the Pacific Ring of Fire, Kelud is known for large explosive eruptions throughout its history. More than 30 eruptions have occurred since 1000 AD. In 2007, an effusive explosion filled the crater with a lava dome. It last erupted on February 13, 2014, destroying the lava dome and ejecting boulders, stones and ashes up to West Java about 500 kilometers from Mount Kelud. The crater filled with water during the rainy season.

1334 eruption

The eruption history of Kelud is quite unique in Indonesian history, because it was one of the few volcanoes whose activities were recorded in Indonesian historical accounts. In 1334 CE, Mount Kelud erupted. Religious groups argued that this was the divine sign that Batara Gurunata has manifest Himself on earth, reincarnated as the Javanese king. This account also describes the local Javanese psyche at that time (and even up to present) that regarded the natural event such as volcanic eruption, as the divine sign from the gods.

On May 19, 1919, an eruption at Kelud killed an estimated 5,000 people, mostly through hot mudflows (also known as "lahars"). More recent eruptions in 1951, 1966, and 1990 have altogether killed another 250 people. Following the 1966 eruption, the Ampera Tunnels were built (top and bottom) on the southwestern side of the crater to reduce (not drain out to empty) the water of crater lake and thus reduce the lahar hazard.

1990 eruption

A strong and explosive eruption on early February 1990 produced a 7 kilometres (4 mi) high column of tephra, heavy tephra falls and several pyroclastic flows. More than thirty people were killed. Workers continued to construct the Ampera Tunnel despite the still-hot (90–400 °C or 200–800 °F) pyroclastic flow deposits which reached as high as 25 m (80 ft) and buried the tunnel's mouth.

2007 eruption

On October 16, 2007, Indonesian authorities ordered the evacuation of 30,000 residents living near Kelud, after scientists placed the volcano on the highest alert level, meaning that they expected an imminent eruption.

Kelud erupted at about 3 p.m. local time on Saturday, November 3, 2007. The eruption was confirmed by the Indonesian government's Centre for Vulcanology and Geological Hazard Mitigation. Although no visual confirmation was possible when the eruption began because the volcano's peak was shrouded by clouds, Indonesian government volcanologists said seismic readings showed an eruption was under way.

More than 350,000 people lived within 10 kilometres (6.2 mi) of the volcano. Surabaya, Indonesia's third-largest urban area and home to one of the country's busiest airports, is 90 kilometres (56 mi) to the northwest. Although local inhabitants were ordered to leave their homes in mid-October, many either did not evacuate or returned. Many villagers were reported fleeing the area in panic after reports of the eruption. But by early Saturday evening, Indonesian officials said the eruption that day had not been very large at all. Seismological equipment near the volcano's crater was still operating, and scientists said that indicated a small eruption at best.

However, early Sunday morning, November 4, Mount Kelud spewed ash 500 metres into the air, indicating a full eruption was taking place. On November 5, new columns of smoke and steam erupted from the crater. Boiling water cascaded down the flanks of the mountain from the crater lake, and seismological equipment near the crater ceased working. Indonesian authorities said about 25,000 people remained in the danger zone, ignoring evacuation orders.

The following day, a lava dome rose through the centre of the crater lake atop the mountain. Closed-circuit television cameras showed the 100-metre (330 ft) long oblong island had pushed about 20 metres (66 ft) above the surface of the lake. The volcano continued to emit smoke, with plumes reaching a kilometre (3,280 feet, or six-tenths of a mile) into the atmosphere.

But after 48 hours of smoke and ash but no lava, Indonesian officials declared on November 8 that no eruption was immediate. Officials said the volcano was experiencing a "slow eruption" and was unlikely to explode as it had done many times in the past century.

By November 12, Mount Kelud began spewing lava into its crater lake. The lava dome, which had expanded to 250 metres (270 yd) long and 120 metres (130 yards) high, cracked open and lava began oozing into the surrounding water. Smoke rose more than two kilometres (1.2 miles) into the air, and ash dusted several villages around the volcano. On November 14, smoke billowed 2.5 kilometres (1.6 mi) into the air, and light ash covered villages 15 kilometres (9.3 mi) away. The hot lava dome occupied the lake crater and, consequently, the lake disappeared.

2014 eruption

Kelud erupted on February 13, 2014. The eruption sent volcanic ash covering an area of about 500 kilometres (310 mi) in diameter. Ashfall occurred over a large portion of Java island, from Malang to the west, as well as Central Java and Yogyakarta. The eruption prompted about 76,000 inhabitants to evacuate their homes. Two people were reported dead after their houses collapsed from the weight of ash. An elderly man also died from inhaling the ash. The ash also reportedly reached the western region of Java by February 14 afternoon, where traces of volcanic ash were found in Bandung and surroundings.

Ashfall from the eruption "paralyzed Java". Seven airports were closed. Financial losses from the airport closures were valued in the billions of rupiah (millions of US dollars). Significant damage was caused to a variety of manufacturing and agricultural industries. The ashfall meant companies such as Unilever Indonesia had difficulty distributing their products throughout affected areas. Apple orchards in Batu, East Java, posted losses of up to Rp 17.8 billion, while the dairy industry in the province posted high losses.

On February 14, 2014, major tourist attractions in Yogyakarta and Central Java were closed to visitors after being severely affected by the volcanic ash-fall from the eruption of Kelud volcano a day earlier. Workers covered the iconic stupas and statues of Borobudur temple to protect the structure from volcanic ash. Owing to the ash, many tourists cancelled their reservations at hotels throughout Central Java.

Indonesian military personnel used water cannons to clear roads, and were later involved in reconstruction efforts in the areas surrounding Kelud. Citizens did likewise, although with less powerful equipment. Political parties helped distribute food to victims of the eruptions. By February 20 most businesses and attractions which had closed owing to the ash-fall had reopened, although cleaning operations were still ongoing.

The volcano's alert status was downgraded on 21 February, and the exclusion zone reduced from 10 kilometres (6.2 mi) to 5 kilometres (3.1 mi). By early March most of the 12,304 buildings destroyed or damaged during the eruptions had been repaired, at an estimated cost of Rp 55 billion.
