Death toll 280 & counting: what is the science behind Kerala’s deadly landslides?
Haunting images reveal uprooted trees, homes reduced to rubble, and bridges shattered, all swallowed by muddied waters. Each scene tells a story of loss, despair, and the enduring resilience of those affected

The landslides in Wayanad, a tourist-friendly district in the southern Indian state of Kerala, are rapidly becoming one of the most devastating natural disasters the region has ever seen. Entire areas in Chooralmala and Mundakai villages have been washed away, with local media reporting the destruction of over 250 homes. Tragically, the death toll has surpassed 280, marking a grim chapter in the region’s history.
The disaster, the worst since the devastating floods of 2018, has left a heart-breaking trail of destruction. Haunting images reveal uprooted trees, homes reduced to rubble, and bridges shattered, all swallowed by muddied waters. Each scene tells a story of loss, despair, and the enduring resilience of those affected.
Nestled in the rugged terrain of the Western Ghats, Wayanad is renowned for its stunning vistas and is a cherished tourist destination, attracting over 100,000 visitors each year. This picturesque district, home to indigenous tribes and dotted with lush tea and cardamom estates, holds a unique charm. Yet, beneath its beauty lies a history of vulnerability, and prone to landslides.
A 2011 report by a panel of experts led by ecologist Madhav Gadgil classified the entire Wayanad region as “fragile, medium fragile, and less fragile,” highlighting its susceptibility to landslides
A 2011 report by a panel of experts led by ecologist Madhav Gadgil classified the entire Wayanad region as “fragile, medium fragile, and less fragile,” highlighting its susceptibility to landslides. This designation underscores the delicate balance of this ecologically sensitive area, where the enchanting landscape masks the underlying risks faced by its resilient inhabitants.

In the past decade alone, landslides have claimed the lives of 255 people in Kerala. In 2018, 109 people died in landslides, and in 2020 and 2021, around 182 lives were lost to these disasters. August 2020 saw a particularly deadly landslide in Pettimudi, which resulted in 66 fatalities.
Understanding Landslides
Landslides, also known as landslips, encompass a dramatic and diverse array of ground movements that can reshape landscapes in an instant. These natural events, ranging from rockfalls and mudflows to slope failures and debris flows, occur across various environments. Whether cascading down steep mountain ranges, eroding coastal cliffs, or shifting underwater as submarine landslides, these movements highlight the dynamic and unpredictable nature of the terrain. As communities and scientists grapple with their impacts, the stories behind these powerful geological forces continue to unfold.
While gravity is the main force behind landslides, various factors influence slope stability, creating conditions that make a slope vulnerable to failure. Often, a specific event like heavy rainfall, an earthquake, or construction activity triggers a landslide, though the precise cause isn’t always identifiable.
Human activities often exacerbate landslides. Urban sprawl, mining, and deforestation contribute to land degradation, reducing soil stabilization by vegetation. Additionally, global warming and other environmental impacts increase the frequency of extreme weather events, further triggering landslides.
The Catastrophe in Wayanad
Mundakai, the epicentre of a series of landslides, received 572 mm of rain in 48 hours. According to the India Meteorological Department, rainfall exceeding 204.4 mm per day is considered extremely heavy. Experts attribute the landslide in the Mundakai region to this heavy rainfall. In 2019, the Puthumala landslide occurred just two to three kilometres from the current disaster site.
Dr. S. Abhilash from the Cochin University of Science and Technology highlighted the region’s geographical vulnerability. He stated in a video shared on the university’s official Facebook page that heavy nighttime rain was the primary cause of the landslide.
The phenomenon, technically known as a mesoscale mini cloudburst, involves 15 to 20 cm of rain falling within two to three hours. Such events are now occurring in North Kerala, significantly impacting the region
In the past two weeks, the Konkan region (a stretch of land by the western coast of India) experienced heavy rainfall due to a low-pressure area from the Gujarat coast to North Kerala. North Kerala received 50 to 70 percent more rain than usual during this period, with areas including Wayanad recording over 24 cm of rain. The thickening of clouds in the southeast Arabian region contributed to this heavy rainfall.
This phenomenon, technically known as a mesoscale mini cloudburst, involves 15 to 20 cm of rain falling within two to three hours. Such events are now occurring in North Kerala, significantly impacting the region.
Mesoscale Cloudbursts and Kerala Floods
An earlier study published in Science Direct linked mesoscale cloudbursts to the 2019 Kerala floods. Researchers at the Advanced Centre for Atmospheric Radar Research (ACARR), Cochin University of Science and Technology (CUSAT), observed that rainfall exceeding 50 mm in two hours was reported in many places from 8 a.m. to 10 p.m. on August 8, 2019.
The Western Ghats, which run through Kerala, are prone to frequent landslides during the biannual monsoon seasons. The Gadgil Committee report classified areas like Kavalappara in Malappuram district and Puthumala in Wayanad district, which experienced fatal landslides in 2020, as Ecologically Fragile Land (EFL). Climate change exacerbates these issues.
Kerala has faced significant challenges due to climate change in recent years. The state endured a severe drought in 2015, followed by the devastating Ockhi cyclone in 2017. In 2018 and 2019, massive floods and landslides wreaked havoc.
The extreme rainfall of August 2019, which caused landslides and mudslides, leading to downstream flooding, was a ‘mesoscale cloudburst’—a rare phenomenon in Kerala usually seen in North India, according to the study published in ScienceDirect.
Given the increasing intensity of rainfall, the probability of landslides in the Western Ghats’ high to mid-land slopes during the monsoon seasons rises. Human intervention, primarily for crop cultivation, has altered the Western Ghats, making the region more prone to landslides of various scales.

New Research Could Allow People to Correct Robots’ Actions in Real-Time
Through basic interactions like pointing to the object, tracing a path on a screen, or physically nudging the robot’s arm, you could guide it to complete the task more accurately.

A breakthrough framework developed by researchers from MIT and NVIDIA may soon allow people to correct a robot’s actions in real-time using simple, intuitive feedback—similar to how they would guide another person.
Imagine you’re doing the dishes and a robot grabs a soapy bowl from the sink—but its gripper misses the mark. Instead of having to retrain the robot from scratch, a new method could enable you to fix its behaviour in real time. Through basic interactions like pointing to the object, tracing a path on a screen, or physically nudging the robot’s arm, you could guide it to complete the task more accurately.
This new approach eliminates the need for users to collect data and retrain the robot’s machine-learning model, unlike other traditional methods. Instead, it allows the robot to immediately adjust its actions based on user feedback to get as close as possible to fulfilling the user’s intent.
In tests, the framework’s success rate was 21 percent higher than an alternative method that did not leverage human corrections.
“This approach is designed to let robots perform tasks effectively right out of the box,” says Felix Yanwei Wang, an MIT graduate student in electrical engineering and computer science (EECS) and the lead author of a paper on the framework. “We can’t expect laypeople to gather data and fine-tune models. If a robot doesn’t work as expected, users should have an intuitive way to fix it.”
Wang’s co-authors include Lirui Wang PhD ’24, Yilun Du PhD ’24, senior author Julie Shah, MIT professor of aeronautics and astronautics and director of the Interactive Robotics Group at CSAIL, along with Balakumar Sundaralingam, Xuning Yang, Yu-Wei Chao, Claudia Perez-D’Arpino PhD ’19, and Dieter Fox from NVIDIA. The research will be presented at the upcoming International Conference on Robots and Automation.
A New Approach to Robot Correction
Currently, many robots use generative AI models trained on vast amounts of data to perform tasks. These models can solve complex tasks but often struggle to adapt to real-world situations that differ from their training environment. For example, a robot might fail to pick up a box from a shelf if the shelf in the user’s home is arranged differently than in its training environment.
To address this, engineers often collect new data and retrain the model—a time-consuming and costly process. However, the new MIT-NVIDIA framework allows users to interact with the robot during deployment, correcting its behavior in real time without the need for retraining.
“We want users to guide the robot without causing mistakes that could misalign with their intent,” says Wang. “The goal is to provide feedback that adjusts the robot’s behavior in a way that is both valid and aligned with the user’s goals.”
The system offers three ways for users to provide feedback: they can point to the object they want the robot to interact with, trace a desired trajectory on a screen, or physically nudge the robot’s arm. Wang explains, “Physically nudging the robot is the most direct way to specify user intent without losing any of the information.”
Ensuring Valid Actions
To avoid the robot making invalid moves—like colliding with nearby objects—the researchers developed a sampling procedure. This technique ensures that the robot chooses actions that are both feasible and aligned with the user’s request.
“Rather than just imposing the user’s will, we allow the robot to take the user’s intent into account while ensuring the actions remain valid,” Wang says.
The researchers’ framework outperformed other methods during tests with a real robot arm in a toy kitchen. While the robot might not always complete tasks immediately, the system allows users to correct it on the spot, without waiting for it to finish and then provide new instructions.
The framework also has the potential to learn from user corrections. For instance, if a user nudges the robot to pick up the correct bowl, the robot could log this action and incorporate it into its future behavior, gradually improving over time.
“The key to continuous improvement is having a way for users to interact with the robot,” says Wang. “This method makes that possible.”
Looking ahead, the researchers aim to improve the speed of the sampling procedure and test the framework in new, more complex environments, paving the way for robots that are more adaptable to real-world scenarios.

Starliner crew challenge rhetoric, says they were never “stranded”
Sunita Williams and Barry Wilmore don’t require a “rescue mission.” The veteran astronauts challenged some misconceptions the public has had about their over-extended stay aboard the International Space Station (ISS), following the Boeing Starliner mishap last June.

Last year on June 5th, NASA astronauts Sunita Williams and Barry Wilmore were on a flight testing mission to dock a Boeing Starliner spaceraft to the International Space Station (ISS). Set to return just eight-days later, their mission met with an ill-fated death. A few thrusters failed, in addition to a helium leak onboard, rendered the Boeing Starliner spacecraft too unsafe for NASA’s liking. The agency’s stubborn refusal to let their astronauts be under harm’s way, meant the Starliner returned to earth later in September without its crew.
In the months passing since then, Williams and Wilmore never left the public gaze. Media headlines and TV news anchors have taken to report the event as a major predicament. This is despite the fact, that the astronauts were neither stranded, nor left alone. Williams and Wilmore weigh in on the issue recently during a live interaction with the media.
“Butch (Barry Wilmore) and I knew this was a test flight,” Sunita Williams said to CBS News. “We knew that we would probably find some things (wrong with Starliner) and we found some stuff, and so that was not a surprise.”
Musk made a statement there that sparked controversy. “They were left up there for political reasons.”
This is not to say the situation the duo found themselves in is unprecedented; for it is indeed unprecedented. When NASA had Boeing Starliner‘s software reconfigured and return to earth in one shape. NASA had the benefit of doubt, given their original assessment was made with the best possible evidence available at the time; and not to compromise upon crew safety. As of latest plans, Williams and Wilmore will return to earth by late-March 2025 at the earliest.
But the rhetoric has reinforced calls to put together a “rescue mission.” SpaceX CEO Elon Musk, who advises incumbent US President Donald Trump, claimed at a Fox News interview that his proposal to bring the astronauts back in September was rejected by the previous administration led by President Joe Biden. Musk made a statement there that sparked controversy. “They were left up there for political reasons.”
Narratives draw ire from the space community
Musk’s comments drew ire from other veteran astronauts. Andreas Mogensen, a former ISS commander during Expedition 70, reacted to Musk’s comment on X to say, “What a lie. And from someone who complains about lack of honesty from the mainstream media.” Musk responded in kind soon there after, aggressively standing his ground. However, the astronauts themselves found the claims unsubstantiated.
According to WCVB Boston, Barry Wilmore himself said, “I have not heard that … I’m not sure that could be the case based on what I know. We came up here with a plan to return, and the plan changed.” NASA themselves had issued a clarification in the aftermath of Musk’s own comments, claiming it had never received a direct proposal from SpaceX for any mission. Nor did they warrant such a “rescue mission”, as now President Trump has called on for.
Political considerations are not a factor in changing the timelines in the ISS expeditions. “The White House was very good about letting us make safety decisions and leaving that to the experts at NASA,” Bloomberg reported Pam Melroy, an ex-NASA administrator involved in the mission, as having said.

“Help us change the rhetoric …”
Risks and derailed plans are part and parcel of space travel, and something space agencies draw backup plans for. Much of the public angst and concern for the astronauts is the loneliness arising from prolonged isolation in space, and fears of mishap with the ISS.
“That is what the human space flight program is; it prepares for any and all contingencies that we can conceive of, and we prepare for those,” Newsweek reports Sunita Williams as having said. Health professionals on ground have helped monitor and manage their physical and psychological fitness. Inadvertently, they contribute to research studying the human body’s ability to adapt in the micro-gravity conditions; as well as psychological resilience and the astronauts’ ability to handle stress. But this is nothing astronauts cannot handle. In fact, Williams compared her situation with that of a tourist. “I call it a little vacation from earth.”
“So if you’ll help us change the rhetoric, help us change the narrative…let’s change it to ‘prepared and committed’ rather than what you’ve been hearing,” WCVB Boston reported Williams as having said.
They have had astronauts from the Crew 8 expedition give them company during the arrival in June, assisting them with their microgravity-based scientific experiments. In September, they were joined by a new party of astronauts of the Crew 9 mission – Roscosmos’ Alexander Gubnov, and NASA’s Nick Hague – replacing the astronauts from Crew 8.
In addition to extra clothing and stockpile of food, NASA had left two extra seats were left empty for Williams and Wilmore to return along with Gubnov and Hague on their return later this March or April, when astronauts from upcoming Crew 10 dock later this month. Given there is a spacecraft docked to the ISS at all time, they have all what it takes to evacuate during an emergency.
“So if you’ll help us change the rhetoric, help us change the narrative…let’s change it to ‘prepared and committed’ rather than what you’ve been hearing,” WCVB Boston reported Williams as having said.
