Three dead and five missing following landslide at construction site in Kerala.

Three people have died and another five are missing following a landslide at a construction site in Wayanad District, Kerala, at about 1.00 pm local time on Tuesday 7 July 2026. The three dead men have been identified as labourers Anmol Gorai from Jharkhand, Vikas Kumar Singh from Bihar and Chandrabhan Pal from Madhya Pradesh. The incident happened amid heavy rainfall associated with the summer monsoon, which appears to have triggered the collapse of a large pile of earth produced by the construction of a road tunnel intended to connect the town of Meppadi in Wayanad District to the village of Anakkampoyil in the neighbouring Kozhikode District. Landslides are a common problem after severe weather, as excess pore water pressure can overcome cohesion in soil and sediments, allowing them to flow like liquids. Approximately 90% of all landslides are caused by heavy rainfall.

The landslide swept across the construction site, over a nearby road where it swept several vehicles away, then over a temporary labour camp for workers at the site, then a local church and house. All work at the site, other than searching for the missing persons, has stopped pending an investigation into the incident.

Managers at the site, which is being operated by Dilip Buildcon Limited, have claimed that the landslide started on land above the construction site, and was therefore not their fault. However, local authorities have observed that the company appears to have been in breach of at least two directives issued to by the Kerala Public Works Department, one of which was to remove the spoil heap, which was perceived as dangerously large, while the other was not to allow work on the site to be carried out on the site during heavy rainfall, due to the possibility of landslides.

The tunnel project was approved in 2020, and is intended to relieve pressure on the Thamarassery Ghat Road, which is prone to closures due to landslides during the monsoon season. However, from the outset it has been opposed by environmental groups in Kerala, who were worried that it would affect areas which form a key part of the Western Ghats Biodiversity Hotspot, in particular forests used by wild Elephants, and that there was a danger of tunnelling activities making the hillsides more prone to landslides.

These concerns form part of a wider dispute between the Indian Government, which considers large infrastructure projects to be a vital part of its mission to raise millions of Indian citizens out of poverty, and environmentalists, who consider many of these projects to be poorly thought out, and not to take into account the special environmental needs of places such the Western Ghats, nor the current or projected future climate of the region. While such objections are often depicted by India's politicians as being anti-development sentiments which will condemn future generations to poverty, environmentalists worry that large projects which do not take into account the environment and climate risk failure, leaving the areas affected without any meaningful improvement to infrastructure and potentially significant environmental degradation, leaving local communities worse off than they are now.

Monsoons are tropical sea breezes triggered by heating of the land during the warmer part of the year (summer). Both the land and sea are warmed by the Sun, but the land has a lower ability to absorb heat, radiating it back so that the air above landmasses becomes significantly warmer than that over the sea, causing the air above the land to rise and drawing in water from over the sea; since this has also been warmed it carries a high evaporated water content, and brings with it heavy rainfall. In the tropical dry season the situation is reversed, as the air over the land cools more rapidly with the seasons, leading to warmer air over the sea, and thus breezes moving from the shore to the sea (where air is rising more rapidly) and a drying of the climate.

Kerala has a complex seasonal cycle, driven by the presence of the Western Ghats mountain range, which largely block the dry northerly winds which dominate the climate of much of India, and its proximity to the equator, which leads to a double monsoon system. Such a double Monsoon Season is common close to the equator, where the Sun is highest overhead around the equinoxes and lowest on the horizons around the solstices, making the solstices the coolest part of the year and the equinoxes the hottest. In Kerala this results in a Southwest Monsoon, which lasts from May to September, and is driven by winds from the southern Arabian Sea dumping water onto the Western Ghats, followed by a Northwest Monsoon, which lasts from October to December, where winds from the Bay of Bengal do the same. Of the two monsoons, the southwest is the wetter, due to the proximity of the sea, with June typically being the wettest month, with an average of 341 mm of rain falling in the month.

Woman killed by Elephant in Kerala State, India.

A woman has died after being trampled by an Elephant on Monday 8 June 2026 in the village of Sinkukandam near the town of Suryanelli in the Idukki District of Kerala State, India. The woman, identified as Mari, a 36-year-old widow, mother of two, and day-labourer, encountered a mother Elephant with a calf while escorting her 11-year-old son to catch a school bus, at about 8.30 am local time. Both were attacked by the Animal, and subsequently rushed to a local hospital by a passing auto-rickshaw driver. Here Mari was pronounced dead, while her son, Dakshan, was transferred to the Kottayam Government Medical College Hospital for further treatment.

The village is close to the Chinnakanal Reserve, which is home to a population of 18 Elephants. About 50 people are thought to have been killed by Elephants in and around Chinnakanal since 1990, ten of them by a single male known as 'Arikomban' who was eventually relocated away from the area by the Kerala Forest Department in 2023. This has placed considerable strain on the local Human population, and their ability to live alongside the area's Elephants.  

The major problem appears to be that the Chinnakanal Reserve covers an area of about 4 km², although only about half of this is utilised by the Elephants, who instead spill out into nearby farms and villages, often stealing food from Humans and coming into conflict with them. In an attempt to manage this conflict the Forest Department has set up a system alerts on social media and messaging platforms, which message people warning them that Elephants are in their area. However, local people have complained that they are not simply able to simply stop going about their daily business whenever Elephants wander into the area. On the day of the latest incident an alert had been put out, but visibility was very low due to rains and fog, apparently causing the victims to come close to the Elephants without realising the danger they were in until too late.

In 2022 Raju Francis of the Kerala Forest Development Corporation produced a report recommending the construction of a series of solar-powered electric fences to protect farmland and residential areas from Elephants emerging from the forest. Despite agreeing to this proposal, four years on the Forest Department has yet to install a single stretch of fencing, and is unable to confirm when this will begin, something which local people have described as grossly negligent, leaving their property and families vulnerable to Elephant attacks.

Asian Elephants, Elephas maximus, are classified as Endangered under the terms of the International Union for the Conservation of Nature's Red List of Threatened Species, as the population has declined by more than 50% over the last three generations (about 75 years for Elephants). There are currently about 50 000 Asian Elephants (although Elephants are notoriously difficult to count, despite being such large Animals) scattered across Bangladesh, Bhutan, Cambodia, China, India, Indonesia, Laos Malaysia, Myanmar, Nepal, Sri Lanka, Thailand, and Vietnam. However, this population is now highly fragmented, with most Elephants living in small groups, reproductively isolated from other groups, and often coming into conflict with local Human populations as the land allocated to Elephants shrinks.

At least 361 people dead following series of landslides in Kerala State, India.

At least 361 people have lost their lives, with another 206 still missing and more than 273 having suffered injuries, following a series of landslides in the Wayanad District of Kerala State on 30 July 2024. The landslides occurred when heavy rains associated with the onset of the onset of the annual monsoon. Landslides are a common problem after severe weather events, as excess pore water pressure can overcome cohesion in soil and sediments, allowing them to flow like liquids. Approximately 90% of all landslides are caused by heavy rainfall. The landslides have affected the villages of Punjri Matom, Mundakkai, Chooralmala, Attamala, Meppadi and Kunhome.

Wayanad District is thought likely to have become more vulnerable to landslides due to the extensive deforestation it has suffered in recent years. Tree roots can help to hold soft sediments together on slopes, and deforestation is often associated with landslides. According to a 2022 study led by Kakoli Saha of the School of Planning and Architecture, Bhopal, between 1950 and 2018 Wayanad District lost around 62% of its forest cover, mostly being replaced with tea plantations, which have much shallower root systems, failing to stabilise steep slopes.

Cigaritis meghamalaiensis: A new species of Lycaenid Butterfly from the southern Western Ghats of India.

Lycaenid Butterflies or 'Blues' are a widespread and highly successful group of Lepidopteran Insects, noted for their blue or metallic colouring. With about 6000 known species, Lycaenids are found on all continents and comprise about 30% of all described Butterfly species. The group is particularly notable for its relationship with Ants, with the females of many species laying their eggs in or near to Ant nests, and the young of many species being able to induce the Ants to feed them while they mature within the nest. This relationship appears to have mutualistic roots, with some members of the group having larvae which are guarded by the Ants while they feed, and which produce a sugar-rich honeydew which the Ants consume. Silverlines, Cigaritis spp., are a genus of Lycaenid Butterflies found across Africa, South and Southeast Asia.

In a paper published in the journal Entomon on 31 December 2023,  Ramasamy Kamaya Naicker of  Saptur Palace and the Vanam Trust, Sujitha Prabhakaran Chandrika of the Department of Zoology at the University of Kerala, Baiju Kochunarayanan of Sreerangam, Jebine Jose of Kaduvathookil House, Manoj Kripakaran of Shyladhri, Rajkumar Chidambaram Palaniappan, also of the Vanam Trust, Vinayan Padmanabhan Nair of Nethaji Housing Colony, Kalesh Sadasivan of Greeshmam and the Travancore Nature History Society describe a new species of Cigaritis from the southern Western Ghats of India.

The new species is named Cigaritis meghamalaiensis, where 'meghamalaiensis' means 'from Meghamalai' , in reference to the region where it was discovered; the name 'Meghamalai' means 'cloud mountain', so the name also refers to the subtropical montane cloud forests where the species is found. The species was first observed at high elevations within the Periyar Tiger Reserve in Kerala State, and subsequently also found in the adjoining Meghamalai Mountain Range of Tamil Nadu.

(2023).

Males of Cigaritis meghamalaiensis have forewings that are black on the upper side with extensive metallic blue markings, and hindwings that are grey with blue markings. In females the forewings are grey with metallic blue markings and the hindwings are a lighter grey with blue markings. In both sexes the undersides of the wings in both sexes are a pale pinkish brown with pinkish orange markings.

(2023).

Butterflies were observed flying between December and June, although they were surprisingly reluctant to the wing, making them easy prey to Spiney Lizards and other predators. They were found only on the fringes of subtropical evergreen forests. Females were observed to fly around trees with populations of predatory Acrobat Ants, Crematogaster spp.. Mating was observed in April, and eggs were laid between April and December, on the bark of trees and shrubs such as Neolitsea spp. and  Clerodendrum infortunatum, always in the presence of Crematogaster wroughtonii Ants, either in dark crevices on the stems or directly in the Ants' nests.

(2023).

Larvae were observed in 'pens' under the bark of the trees, where they were tended by Crematogaster wroughtonii Ants. These pens each contained 3-4 larvae, and appeared to be constructed specifically by the Ants, away from their own nests. This suggests that the relationship is mutual rather than parasitic, with the Ants gaining some benefit from the relationship, possibly consuming some product produced by the caterpillars.

'Killer' Elephant relocated in Kerala.

An Elephant alleged to have killed a number of people in Kerala State, India, has been relocated to a Tiger reserve away from Human populations. The Elephant, a 36-year-old male named Arikomban, is claimed to have killed seven people during raids on Rice stores in the area around Devikulam Forest in Idukki District, although this has been disputed People for Animals, an Indian Animal welfare organization, who claim their investigations have been unable to find any instances of people being directly harmed by the Elephant. What is not disputed, however, is that Arikomban is a notorious Rice-thief, and while he was able to take Rice from older Bamboo-and-Grass stores without causing much damage, as concrete and other modern building materials have become more common, the Elephant has been increasingly causing damage to property during his raids, fueling conflict with local Human populations, who have been petitioning the Kerala Forest Department to have him relocated.

Arikomban has been living around Humans since 1987, when he was a calf and his mother sustained a leg injury and was looked after by villagers near Chinnakkanal, before eventually perishing. Since that time he has tended to live around Humans, and had few interactions with other Elephants. This has included raiding Rice stores for food, something which was for a long time tolerated, but which has become more of an issue over time as the Human population has grown, a problem which has been repeated across India in recent years, where 30 000 wild Asian Elephants (60% of the global total) now co-exist with 1.4 billion Humans (18% of the global total).

The Kerala Forest department initially applied to the Kerala High Court for permission to take Arikomban into captivity, but this was rejected following opposition from Animal welfare groups. A plan was then devised to move the Elephant to the Parambikulam Tiger Reserve, about 175 km from the area where he has been living, but this was opposed by people living close to the reserve, who were alarmed by Arikomban's reputation. Following this, it was decided to relocate the Elephant to the Periyar Tiger Reserve, about 80 km from Arikomban's current home. Concerns were raised that the local Human population around Periyar might also reject Arikomban, but this appears not to have been the case, with large crowds turning out to great the Elephant as he was brought to the reserve.

Arikomban is reported to have received a deep cut on the trunk during his capture, for which he was treated before being released. He was also fitted with a radio collar to monitor his progress. He was provided with several barrels of water laced with antibiotics for his wound, which were later found overturned, as well as several stores of food which it is hoped will help sustain him while he adapts to foraging in the wild. Tracking collar data has revealed that he was approached by a small herd of six local Elephants shortly after his release, but that these retreated without any apparent interaction.
