Near the smallest town in the world, Hum, in the centre of the Istrian peninsula in Croatia, there is a small desert. The Mučan badland is located in the flysch complex with an area of approximately 2.5 ha. The high erodibility of the fine-grained sedimentary rock, marl, leads to the formation of badlands, which are particularly susceptible to slope movements.

The photo was taken on 20 May 2016, from the hotel balcony in Alta Badia (Italy), one day after the student excursion on the Vajont dam landslide. The length of the landslide, measured from Google Earth satellite images is approximately 50 m, and the width is approximately 20 m. Although the activity of the landslide is probably dormant, the morphology is very well preserved due to grassland maintenance.

A drone photo of this unique landslide was taken on 4 June 2019, in Bednja Municipality, Croatia. The landslide was activated by heavy rainfall and left a specific footprint on the terrain in the form of the Greek letter delta (Δ).

To a family in Prebukovje village, in Hrvatsko zagorje, this landslide became a part of their backyard. Being 20×35 m large, its toe nearly reached the family doorstep. Being insecure about the landslide activity and waiting for remediation, the residents were glad to meet scientists researching their everyday troubles.

The landslide is located in the Podsljeme zone in the City of Zagreb (Croatia). It was activated on 13 February 2014 after a prolonged heavy rainfall period. The block of marl rock was translated about 60 meters, which opened a smooth sliding surface measuring approximately 60×70 m. The total landslide area is approx. 12,000 m2.

In Hrvatsko zagorje, in the Meljan Village, Croatia, a landslide occurred as a result of a heavy rainfall event. The landslide toe was heavily affecting the road, barely avoiding houses and yards. Slowly pushing the nearby fence and being in close proximity to buildings, this 25×60 m landslide is waiting for remediation.

The Corvara landslide is an active rotational landslide located uphill of the village of Corvara in Badia, Italy. The deformation of the slope is up to tens of meters
per year in the most active track and source zones. The photo shows a section of the source zone of the retrogressive Corvara landslide and a professor’s
attempt to support it. The photo was taken in 2016 during a student excursion in Dolomites.

The Racari landslide is located below the Racari village in the City of Buzet (Croatia). It was activated on 18 February 2014 after a prolonged heavy rainfall period. The photo was taken few days after landslide occurred and shows the landslide body intermittent with few meters deep cracks. Buzet area is mostly built in Paleogene flysch rock mass where many landslides are activated after heavy rainfall period.

The Slani Potok gully is the largest gully (0.48 km2) in the Vinodol Valley. More than 100 debris slides are located in this gully. Landslides are very small to
moderate-small, shallow to moderate shallow. Most of them have been initiated along the gully channel wall margins, and extend to the channel bottom. A
photo was taken in February 2014. The date of the landslide activation is unknown.

The photo presents a small landslide located in the Flegi village, municipality of Motovun, Istria. This landslide is one of several dozens of small landslides
activated in the villages of Flegi and Petehi after the rainfall event that lasted from 7th to 11th December 2020. The terrain is composed of flysch deposits,
with sandstones, marls and siltstones. Predominately shallow translational slides have been activated in the zone of weathering. The height of the main scarp is
approximately two meters. The landslide area is only a few square meters.

The landslide is located in Mala Dubračina gully in the Vinodol Valley. It was reactivated in February 2016. The previous landslide activity was documented in 1965. The landslide crown was formed at the local road connecting the county road and Rupe village, passing along the gully channel border. The type of landslide is debris slide. The area is approximately 2,000 m2.

The Petrinja Earthquake Ml=6.2 occurred on 29 December 2020 at 12.19 pm caused significant damage and casualties. Lateral spreading was identified on 27 locations at the riverbanks of Kupa, Sava, Glina and Maja rivers in Sisačko-Moslavačka County. The lateral spreading damaged the Kupa River protection embankment near the Stara Drenčina settlement in length of 600 m causing total displacement of the riverbank of about one meter in Kupa River.

Landslide drone photo was captured in Vinagora village near Pregrada. After the activation, the landslide undermined the family house and the associated building. The landslide was prospected as part of the Commission of the Ministry of Construction and Physical Planning established for evaluation and control of landslides at the territory of the Republic of Croatia.

Snow melting and heavy rainfall activated catastrophic landslide in Hrvatska Kostajnica, Croatia, on 13 March 2018. Ten houses in the landslide foot were completely destroyed due to uplifting and bulging of the displaced mass. Residents of these houses were not warned in advance, but fortunately they escaped the moving landslide without fatalities.

The landslide is located in Bednja Municipality (Croatia). Abundant landslide event with more than 900 (re)activated landslides in the hilly areas of NW Croatia occurred in winter 2012/2013 due to the prolonged heavy rainfall periods and the rapid melting of a thick snow cover. Precipitations and human activity are the primary triggers of landslides in NW Croatia.

In landslide science, the eternal question is whether small landslides are relevant for recording on maps and taking measures to reduce losses. What do you
think, what would be the answer of Ms. Slavica, the owner of this outbuilding, who has no possibility of repairing the damage? Ms. Slavica and her small landslide are located in Bednja, the poorest municipality in Croatia.

The Red Beach is located at the south-eastern part of the active volcanic island Santorini, Greece, and is one of the most famous beaches within the Aegean and Mediterranean Seas due to its particular color. In August 2013, a rockfall occurred, fortunately, during the night, and the debris with older rock detachments composed of volcanic rocks are evident along the entire length of the cliff over the beach.

Rzenik mountain rockfall cuts off hiking trail. On 26 February 2021, after a period of heavy rain and an unusual warm temperature, a part of the northern wall of Triassic limestone collapsed. The event produced about 800,000 m3 of material and was even detected on several seismographs. Deposit area was 13 ha with individual rock blocks of the size up to 2,000 m3 or 20×15 m.

In July 2017, the slope through which the state road D512 Makarska – Vrgorac passes was wholly burned in a fire. As the result, most of the terrain was left without vegetation, making the state road without a natural barrier for rockfalls. The entire slope is covered with more than 1,000 rock blocks of varying volume and shape originating from multiple rockfall source areas.

The rockfall blocks of volcanic breccia in the toe of the Ingólfsfjall Tuya (a flat-topped, steep-sided volcano formed when lava erupts through a thick glacier or
ice sheet) north of the Selfoss settlement, Iceland. The Ingólfsfjall Tuya is 551 m high and mostly built of volcanic breccia. The first vegetation on lava covered
Iceland is moss that also begins to grow on volcanic breccia blocks.

Rockfalls are among the most common landslide types in the Vinodol Valley. Different types of talus deposits have been accumulated at the footslopes of carbonate rock slopes, and in the hypsometrically lower parts of the valley. Olistoliths and boulders can be found there irregularly distributed. The photo is taken in November 2018 at the road connecting the Vinodol Valley with its hinterland.

In the wilderness of Prodani village, near the City of Buzet, this 2×2.5×2 m boulder is a result of a rockfall. Destroying all in front of its path, this boulder is the newest to the collection of older, already accumulated boulders in the area.

The main scarp of a historic landslide from 1880 near the Veli vrh near City of Rijeka location is characterised by steep limestone cliffs 10 to 40 m high. The tensile crack extends for more than 300 m, while debris deposits cover the flysch rock in the lower part of the slope. The photo was taken on 1 January 2022.

With several decades of uncontrolled and rapid urbanisation, frequent extreme rainfall events and more than 7.5 million inhabitants crammed into a tiny area under steep slopes, Hong Kong has become a model for landslide risk management in urbanised environment. Every slope or landslide has its ID. Photo taken while hiking on Victoria’s Peak, Hong Kong Island in August 2018, during UNSAT2018 Conference.

The location of landslide is in city of Ilok in Croatia. The landslide occurred in early 2015 and the local road collapsed. Tensile cracks were visible at the entrances to the collapsed road, which indicated the further spread of the landslide, which endangered the surrounding residential buildings. The landslide is protected by self-drilling rockbolts, reinforcing mesh and shotcrete.

Dubravci Landslide is located on state road DC3, section 012 at km 4+400. The earthquakes in Banovina on 28 and 29 December 2020 caused the activation of the sliding of already potentially unstable material of the road. Landslide is 85 m wide, 35 m long with the main scarp of approximately 3.5 m in height.

Rockfalls caused by heavy rainfall and weathering of the limestone cliffs at Veli vrh result in beautiful and inaccessible steep slopes covered with scree. The photo of the top of the historic Grohovo Landslide from 1880, one of the largest landslides in the Rječina River Valley, was taken in April 2015 during maintenance works on the Grohovo landslide monitoring system.
