Austria, a Central European country dominated by the Alps, has experienced several notable fires in recent years. From lightning-induced forest fires to the deadly Kaprun disaster in 2000, understanding the causes and impacts of these fires is essential. Forest fires in particular pose a significant threat to Austria's vast coniferous forests, with lightning and human activities as the primary ignition sources. This topic explores the challenges faced by Austrian fire brigades and the international cooperation in combating wildfires. Additionally, it highlights the importance of fire safety in transportation following the Kaprun disaster, where a fire in a funicular train tunnel resulted in numerous fatalities.

What You'll Learn
Lightning-induced forest fires
Fire, in Austrian German, is 'Feuer'.
In Austria, a Central European country dominated by the Alps, lightning is the second major reason for forest fire ignition, after human-caused fires. From 1993 to 2010, lightning-caused fires accounted for 15% of documented forest fires, with almost all of these occurring during the summer months. These fires were more frequent at higher altitudes and primarily affected conifer forests in the south and east of the country.
The Austrian Lightning Detection and Information System (ALDIS) plays a crucial role in locating and recording lightning and thunderstorm activity. The dense population and well-established fire brigade network in Austria contribute to the early detection and quick response to lightning-induced fires, which may result in their smaller median burned area compared to human-caused fires.
Climate change and global warming are expected to increase the frequency and severity of lightning strikes and lightning-induced wildfires. The combination of low precipitation, early snowmelt, low humidity, strong winds, and high temperatures creates ideal conditions for these fires to spread. Efforts to reduce lightning-strike wildfires should focus on addressing these climate-related factors and understanding the degree to which lightning strikes contribute to global wildland fires.

The Austrian Fire Brigade
Austria, a Central European country dominated by the majestic Alps, has a diverse landscape ranging from dense forests to picturesque villages. The country's fire brigade has adapted to meet the challenges posed by this varied terrain, with fire departments even in the smallest Austrian villages. The Austrian Fire Brigade Association (ÖBFV) represents the interests of Austrian firefighters at both the European and international levels, advocating for them and fostering cooperation between firefighting organisations.

The Kaprun Disaster
On 11 November 2000, a fire broke out on board a train carrying skiers up to the Kitzsteinhorn Glacier ski resort in Kaprun, Austria. The Gletscherbahn Kaprun 2 funicular train, which had been modernised in 1993, was carrying 161 passengers and one conductor when it unexpectedly stopped inside a tunnel. The fire, which began in the conductor's cabin, destroyed the hydraulic system that controlled the doors, trapping the passengers inside. The conductor reported the fire to the control centre but soon lost contact as the flames burned through a power cable, causing a blackout.
Twelve passengers at the rear of the train managed to break a window and escape downwards, past the fire and below the smoke. The remaining passengers were overcome by toxic fumes and smoke. Eventually, the conductor was able to unlock the doors, but the vast majority of passengers did not survive. In total, 155 people died in the disaster, with 12 survivors.
The cause of the fire was determined to be the failure, overheating, and ignition of an electric heater in the conductor's cabin, which was not designed for use in a moving vehicle. A leak of highly flammable hydraulic oil fuelled the flames, which also caused the train to stop and the doors to fail. The funicular train's structural flaws and lack of safety mechanisms, such as the lack of smoke detectors and fire extinguishers being kept out of the passengers' reach, were found to have contributed to the tragedy. The train complied with area safety codes, which did not address the systems installed during the 1993 upgrade, including onboard electric power, hydraulic systems, and fan heaters intended for home use.
The disaster led to a federal inquiry and legal proceedings, with 16 suspects, including company officials, technicians, and government inspectors, charged with criminal negligence. However, all suspects were eventually acquitted due to insufficient evidence. The incident also inspired a 2003 play by Austrian Nobel Prize winner Elfriede Jelinek, titled "In den Alpen" (In the Alps). The funicular railway was never reopened and was replaced by a gondola lift.

Wildfires in Austria
In Austrian, "fire" can be translated to "Feuer".
Austria is a Central European country dominated by the Alps and has a forest cover primarily of coniferous tree species. While the forests do not fulfil the characteristics of fire-prone ecosystems, forest fires have occurred in the country. The number of fires per year varies between 100 and 300, with about 85% of these being directly or indirectly caused by humans. The causes are wide-ranging and include carelessly discarded cigarettes, forestry work, bonfires, fireworks, sparks on railways, and arson. Lightning strikes are responsible for only about 15% of forest fires, although nearly all lightning-caused fires were found during the summer months, with most taking place in the south and east of Austria.
In the Alpine region, forest fires have so far not posed a major threat to human life and infrastructure, as large forest fires occur much less frequently than in the neighbouring Mediterranean region. Generally, only small areas of up to 1 hectare burn in Austria and no considerable economic or social damage is caused. However, with rising temperatures and changing weather conditions, the danger of extreme forest fire events is expected to increase in the future. Past droughts, like those in the summers of 2003, 2007, 2012, and 2015, have demonstrated the potential impact of forest fires on Austria's ecosystems.
On October 25, 2021, a wildfire started in the Hirschwang region of Lower Austria, about 62 kilometers (38 miles) southwest of Vienna. It quickly grew to 100 hectares (247 acres) but was contained by emergency services, who limited the fire area to 115 hectares (284 acres). The EU's Emergency Response Coordination Center mobilized two Canadair CL-415 air tankers and helicopters from Germany, Italy, and Slovakia to help fight the fire. Around 750,000 liters (198,000 gallons) of water were dropped on the fire by the aircraft. This wildfire was the largest in recorded history for Austria, and it occurred during a period of extreme dryness in the country, with the last similar conditions occurring 35 years prior in September and October of 1986.

Human-caused fires
Additionally, socio-economic factors play a crucial role in human-caused fires. A modelling approach by Arndt N et al. (2013) analysed 59 independent socio-economic variables and found that railroad, forest road, and hiking trail density, along with agricultural and forestry developments, significantly contribute to fire danger. This model helps identify the most vulnerable forest areas and predict fire danger at the municipality level.
Touristic activities have also been studied for their relationship to the spatial occurrence of forest fires. The Austrian Forest Fire Research Initiative (AFFRI) aims to identify forest fire "hot spots" by considering vegetation, climate, and location, as well as the potential for expansion under climate change. This initiative is particularly relevant given that European mountain forests are among the regions most affected by climate change.
Furthermore, human-caused fires often coincide with peaks of heat waves and strong foehn winds. In contrast, lightning-caused fires are more frequent during thunderstorms, which are typically followed by rain and colder weather, inhibiting the spread of fires. The early detection and quick response of fire brigades also contribute to containing human-caused fires, even in remote areas.
To summarise, human-caused fires in Austria are influenced by a combination of factors, including climate change, socio-economic developments, and weather conditions. Understanding these factors is crucial for establishing effective fire prevention systems and allocating firefighting resources efficiently, especially in vulnerable alpine landscapes.
