The Hatlestad Slide was a slide of mud and rock which occurred in the early morning of September 14, 2005 in a rural area in Bergen, Norway, as a result of heavy rainfall. The slide killed three people, wounded seven, and displaced many more, as it hit a row of residential houses in its path while the houses' occupants were asleep. [http://www.aftenposten.no/english/local/article1114723.ece Mudslides hit Vestlandet] , Sept. 15, 2005, retrieved May 18, 2007] The event is notable not only for the loss of life it caused, but also for how it altered Norwegian policies on environmentalism and housing construction, as well as emergency management.

Hatlestad before the slide

Hatlestad Terrasse, a rural neighborhood in the borough of Fana, consists of clusters of housing units in a hilly setting. A single one-lane street connects the housing units to each others and to Osvegen, a major two-lane road directly connecting the town of Os to the area of Nesttun.

Before the Hatlestad Slide, Norway maintained a liberal policy when it came to housing construction on hills. The area of the afflicted housing units were therefore not surveyed for landslide risk before construction was commenced in the sixties, and the risk of landslides did not become known until later. [ [http://www.bt.no/lokalt/bergen/article210485.ece -Husene burde ikke vært bygd] , Bergens Tidende, Sept 28, 2005, retrieved June 14, 2007 no_icon] After construction was finished, there were several incidents of rocks dislodging from the cliff and hitting the road. The rocks did not cause material damage or personal injury, and the municipality took no action besides setting up a warning sign by the road.

However, an order given to the property owners to secure the hill were never responded to, and the case was never resolved.

The Hatlestad landslide

Indirect causes

According to the post-slide report released by Multiconsult and reviewed by NTNU, several potential indirect causes 'should be discussed': First of all, starting weeks before the slide, Western Norway was subjected to record-breaking precipitation and winds, which increased in strength when the remains of Hurricane Maria reached shore. The rainstorm, named "Kristin" by meteorologists, caused floods, traffic jams, material damage and power outages. [ [http://www.dagsavisen.no/innenriks/article266233.ece I værgudenes vold] , Dagsavisen, Feb 4, 2006, retrieved June 14, 2007 no_icon] The precipitation gradually increased pore pressure between the mountain and loose masses, adding to the damage of a process of erosion from surface water. This process may have been further hastened by the possible breach of a water pipe, indicated by a housing unit losing its water supply at around 17 o'clock on the day before the slide. Finally, a garage whch was erected and later demolished in the neighbourhood may have been a contributor, as the fill it rested on never was removed. The weight of the fill may have been a contributor in causing the slide.

The Hatlestad Slide

At approximately 1:30 on the morning of September 14, 2005, the cliff over the houses of Hatlestad Terrasse broke apart. The resulting slide of clay, mud and rocks went through the ground floors of several houses, burying ten people. The houses did not collapse, which meant that residents not on the ground floor were unharmed and able to evacuate without help through first floor windows. The municipality and the city hospital were both put on disaster alert, and a large number of emergency responders, including 12 ambulances, were sent to the scene. The first unit to reach the site was a fire engine which arrived only three minutes after the slide, as it coincidentally was in the area, having just completed a water draining mission, and it was able to use its siren to awaken residents for then to begin an evacuation [http://64.233.183.104/search?q=cache:ZD15-S-KOv8J:www.ba.no/vaeret/flommen/article1742034.ece+hatlestad+site:www.ba.no&hl=no&ct=clnk&cd=18&gl=no Ekstremt vanskelig redningsarbeid] , Bergensavisen, Sept. 14, 2005, retrieved July 16, 2007 no_icon] [http://www.aftenposten.no/nyheter/iriks/article1114657.ece Kvinne omkom i raset] , Aftenposten, Sept 14, 2005, retrieved June 14, 2007 no_icon] . In addition to firefighters and paramedics, the Civil Defense and the National Guard also responded. While search dogs were used in the search for survivors, heavy machinery could not be deployed due to the unstable nature of the ground, which meant that the extraction of buried survivors was made largely by hand, and with tools such as axes and shovels.

Aftermath

Fatalities and wounded

A woman (51) who was buried by the slide was dead by the time she was found and recovered at about 7:30.Placeholder text] A second woman (27) died in hospital a few days later. A four year old, Kristina Hjartåker, died in February the next year.Placeholder text] Several more people were wounded by the slide itself, and from lack of oxygen while buried.Placeholder text]

Evacuation and temporary transportation measures

Due to the threat of more landslides, residents of the neighbourhood were evacuated to neighbors and various hotels around Bergen [ [http://www.bt.no/lokalt/bergen/article196497.ece Måtte flykte i pyjamas] , Bergens Tidende, Sept 15, 2005, retrieved June 14, 2007 no_icon] .

Media coverage

Despite from the fact that the slide took place virtually at the same time as Hurricane Katrina hit New Orleans, it was widely covered by the Norwegian media, and is still referred to in news and articles on severe weather and climate change, sometimes along with the lesser slide of Hetlebakken (see section "Other 2005 precipitation-induced [...] ").Fact|date=May 2007 However, with the exception of the deceased, most notably Kristina Hjartåker, most victims avoided being personally named in the media, with the exception of those who voluntarily gave interviews to papers such as Bergens Tidende and Fanaposten.

The neighborhood and monetary compensation

The fate of the houses and road taken by the slide, as well as those near them, was at first uncertain. Initially, the municipality considered restoring the housing units and the road and leaving it to the owners of the hill to secure it against landslides. This caused great concern among several Hatlestad residents, who were part in owning the hill which would need securing. It was also a concern that the owners' insurances only covered damage to housing, not securing properties against natural disasters, not to mention that the residents were not eager to return to the site due to the nature of the natural disaster.

On the 20. of September a report by the Norwegian consulting engineering company "Multiconsult" proposed and recommended that the houses in question, 16 in all, should be bought by the municipality and demolished. A new street would be built over the site of the houses hit by the rocks and mud. The hill over the street would be secured by a steel net secured by steel bolts drilled into the ground.

The housing units were scheduled for purchase and demolishing, except Hatlestad Terrasse 99, situated next to the source of the slide. The housing units below the slide would also be also secured against landslides by a concrete wall. Furthermore, the municipality gave the residents new, temporary places to live and a monetary compensation.

In addition to the victims of the slide, five Hordaland county municipalities affected by "Kristin" received a monetary compensation of 24,7 NOK (approx. four million USD as of June 2007) from the State in December 2005. Of these, Bergen received 18,8 millions, of which 12,5 were for the securing of Hatlestad Terrasse after the slide. The remaining 6,3 million would cover economic losses following the Hatlestad Slide, as well as a subsequent slide in Hetlebakken (see "Section 4"). The other municipalities receiving compensation were Voss, Fjell, Vaksdal and Odda.

Future of abandoned houses

On November 3, 2007, Bergens Tidende reported that the municipality had almost completed work on securing the area and was looking for an estate agent to help sell 18 properties, consisting of four empty plots and 14 houses. At this point, the houses had been abandoned for two years and their outdoor areas were in need of maintenance. The municipality also recognized that there was a challenge involved in selling the houses due to the recent history of the neighborhood.

The police would start an investigation, never directed at any single individual, following the landslide.

In a press release, the municipality's cabinet leader Monica Mæland apologized for the decision, stating that an investigation would have uncovered all sides of the case.

Effect on disaster readiness

After the slide, evacuation of residents at risk is routinely considered around the country when areas are considered to be at risk from extreme weather. For example, when extreme precipitation hit Nord-Trøndelag in central Norway in 2006, more than 200 people were evacuated.

Finally, in response to the fact that the landslides of Hatlestad and Hetlebakken proved rescue routines after landslides to be unsafe and ineffective, the municipality would establish a 24-man special rescue group to respond to disasters caused by extreme weather. Helge Eidsnes and Tore Kallekleiv of the rescue group voiced budget concerns, stating that recruiting and equipping men for the team would cost about 500 000 NOK (approx. 82 000 USD as of June 2007), which according to him was a large amount to the unit.Placeholder text]
