Measures planned to prevent landslides

The Geotechnical Engineering Office (GEO) on Monday said it will launch a series of risk management and prevention measures to help make sure slopes across the city can withstand extreme weather.
This includes expanding the office's slope catalogue to cover natural hillsides, to better analyse landslide risks and put prevention plans in place.
Tests will be carried out on an automatic system for monitoring slopes with drones during periods of heavy rain, while environmental data will be collected to help the office and rescue teams come up with contingency plans for any incidents.
'After adopting the automatic system, we can allow the drones to arrive at different sites, including our LPM [Landslip Preventive Measures] construction sites, slope and landslide sites,' said Lawrence Shum, a GEO deputy head.
'By doing so, they can capture instantly the information of areas, and help us identify some progress of sites, and actual condition of landslide sites and whether we should deploy more resources to handle emergencies,' he added.
The office said it received a total of 181 landslide reports last year. None of them caused any casualties.
'There were no fatalities last year not because the incidents were minor, but instead, the landslides did not hit any buildings or roads,' Shum said.
In 2023, Hong Kong saw its largest recorded rockfall in a century at Yiu Hing Road in Shau Kei Wan during heavy rain, while a landslide also closed Shek O Road for two days.

Three killed in European wildfires amid heatwave
Three killed in European wildfires amid heatwave A firefighter battles a wildfire in the village of Parafita in Spain. Photo: Reuters Three men died and thousands were forced from their homes on Tuesday as wildfires fuelled by a heatwave scorched southern Europe. Heat alerts were issued in Italy, France, Spain, Portugal and the Balkans, with temperatures expected to soar above 40C. The heatwave is another sign of climate change, which is fuelling longer, more intense and increasingly frequent bouts of extreme heat. "Thanks to climate change, we now live in a significantly warmer world," Akshay Deoras, a research scientist at the meteorology department in Britain's University of Reading told AFP, adding that "many still underestimate the danger". An employee of a Spanish equestrian centre died from his injuries in Tres Cantos, a wealthy suburb north of Madrid, officials said – reportedly as he tried to save horses. Later, officials in Castile and Leon in northwestern Spain confirmed another man had been killed while fighting fires. And a soldier in the Balkan country of Montenegro died and another was seriously injured when their water tanker overturned while fighting wildfires in the hills north of the capital, Podgorica. A child died of heatstroke in Italy on Monday. The equestrian centre employee was the first fatality from dozens of wildfires that have hit Spain since a heatwave began last week. Hundreds of residents of Tres Cantos fled from the fast-moving blaze, which was contained on Tuesday morning. Spanish Prime Minister Pedro Sanchez said on X that rescue services were "working tirelessly to extinguish the fires" and warned: "We are at extreme risk of forest fires. Please be very cautious." Elsewhere, about 2,000 people were evacuated from hotels and homes near the popular beaches of Tarifa in Andalusia, southern Spain. The wildfire broke out near where a similar blaze forced evacuations earlier this month. "We managed to save the residential area at the very last second," said Antonio Sanz, the Andalusia region's interior minister. In Castile and Leon, dozens of blazes were reported, including one threatening Las Medulas, a Unesco World Heritage site known for its ancient Roman gold mines. The head of the regional government of Castile and Leon, Alfonso Fernandez Manueco, vowed "to act quickly and generously" once the fire is over to restore the site "to its full glory as soon as possible". In neighbouring Portugal, firefighters battled three large wildfires, with the most serious near Trancoso in the centre of the country. More than 700 firefighters were deployed there. Temperature records were broken at four weather stations in southern France on Monday and three-quarters of the country was under heat alerts on Tuesday, with temperatures forecast to top 40C in the Rhone Valley. The Rhone department banned outdoor public events. Temperatures started rising on Friday in France's second heatwave in just a few weeks and could remain high into next week, according to the national weather office Meteo-France. Eleven Italian cities, including Rome, Milan and Florence, were placed on red alert on Tuesday due to the heat. (AFP)

France's largest wildfire in decades contained after tearing through wine region
France's largest wildfire in decades was contained on Thursday after burning more than 160 sq km in the country's southern wine region and claiming one life, local authorities said. The blaze erupted on Tuesday and tore through the Aude region, spreading rapidly due to hot, dry weather. Cooler overnight temperatures and calmer winds slowed its advance and allowed firefighters to make headway. Late Thursday, the region's top government official said the fire was contained. However, residents were warned not to return home without authorisation, as many roads remained blocked and dangerous. The fire swept through 15 communes in the Corbières mountain region, destroying or damaging at least 36 homes, with a full damage assessment still under way. One person died at home, and at least 13 others were injured, including 11 firefighters, according to local authorities. Three people who were reported missing have been found safe.

Himalayan flood likely caused by glacier collapse
Himalayan flood likely caused by glacier collapse Water and debris tore down a narrow mountain valley, smashing into the town of Dharali. File photo: Reuters A deadly wall of muddy water that swept away an Indian Himalayan town this week was likely caused by a rapidly melting glacier exacerbated by the rising effects of climate change, experts said on Thursday. Four people have been confirmed dead with scores of people still missing after water and debris tore down a narrow mountain valley, smashing into the town of Dharali in Uttarakhand state on Tuesday. Several people could be seen in videos running before being engulfed as waves uprooted entire buildings, leaving others smothered in freezing sludge. Government officials said shortly after the disaster that the flood was caused by an intense "cloudburst" of rain. However, experts assessing the damage suggested that that was only the final trigger, adding to days of prolonged rains that had already soaked and loosened the ground. PK Joshi, of New Delhi's Jawaharlal Nehru University, an expert on Himalayan hazards, said it appeared the flood was caused by the collapse of debris – known as moraine – that had dammed a lake of meltwater from a retreating glacier. He added that the persistent rainfall over the preceding days or collapse of a moraine-dammed lake contributed to the "sudden high energy flash flood". Cloud cover has obstructed satellite imagery to check for the exact source of the debris, and Joshi cautioned that there was not enough satellite data for a "definitive confirmation". Himalayan glaciers, which provide critical water to nearly two billion people, are melting faster than ever before due to climate change, exposing communities to unpredictable and costly disasters, scientists warn.
