Impact on Regions Like Delhi, Rajasthan, and Gujarat
As the plume drew near the Indian subcontinent, Earth-orbiting satellites and atmospheric monitoring systems detected higher levels of atmospheric particulates. These regions experienced:
Noticeable haze and reduced visibility
Unlike typical smog in winter, parts of Delhi-NCR and western states reported a thin but persistent layer of haze. This was finer and more diffused just like volcanic ash in the upper troposphere.
Drop in air quality indices (AQI)
Spikes in PM2.5 and PM10 concentrations were recorded over cities in Rajasthan and Gujarat. Though volcanic ash at high altitudes does not always mix down to ground level, shifting wind patterns led to episodes of degraded air quality.
Unusual sunsets and sky coloration
The volcanic ash scattered sunlight differently, and residents noticed orange-pink sunsets. This was one of the early visual signs before formal advisories were issued.
Minor health advisories
The state pollution control boards recommended precautions for people with respiratory problems, as sudden spikes in particulates could provoke asthma, allergic reactions, and shortness of breath.
Disruptions to Air Travel
The most immediate impact was on the aviation sector. Volcanic ash is extremely dangerous for aircraft: particles can melt inside jet engines and damage critical components.
India’s air-traffic system reacted swiftly:
Flight delays and diversions
Several airports, especially those in Delhi, Jaipur, Ahmedabad, and Udaipur issued cautionary delays. Some long-distance flights passing through the affected air corridors were diverted or rerouted to avoid ash-heavy regions.
Reduced flight operations in particular time windows
Periods arose when the air-traffic controllers briefly restricted takeoffs and landings because of low visibility or high ash concentration.
Advisories issued by the Directorate General of Civil Aviation (DGCA)
DGCA instructed airlines to:
- Avoid specific altitudes showing higher ash concentrations
- Utilise different flight paths.
- Enhance cockpit vigilance and engine monitoring
- Report any in-flight ash encounters immediately
Operational Challenges for Low Cost & Regional Carriers
Cascading delays hit some airlines, particularly the low-cost ones operating dense flight schedules. Crew rotation, fleet availability, and slot management were disrupted temporarily.
International carriers adjusting routes
The most rerouted flights were those originating from Africa, Europe, and the Middle East and heading to northern Indian cities. This resulted in ripple delays across global networks.
Longer wait times for passengers
With diversions and delays, airport terminals became increasingly congested. Airlines advised passengers to check flight status before leaving home.
Why the Impact was Considered Serious
Although the density of ash was not high enough over India to call for a complete halt in flights, the aviation administration takes a no-compromise approach with volcanic ash. A single case of ash ingestion in an engine can create disastrous results; therefore, the reaction was intentionally conservative.
Broader Implications
Events like this show just how connected climate, geology, and aviation can be. A volcanic eruption a few thousand kilometres away can disrupt travel, logistics, and even public health in India. They reinforce how important robust real-time monitoring systems are-something your background in dashboards, environment-health data, and system integration aligns so well with.

1. The Core Shift: From Narrow Vision Models to General-Purpose Perception Models
For most of the past decade, computer vision relied on highly specialized architectures:
CNNs for classification
YOLO/SSD/DETR for object detection
U-Net/Mask R-CNN for segmentation
RAFT/FlowNet for optical flow
Swin/ViT variants for advanced features
These systems solved one thing extremely well.
But modern multimodal LLMs like GPT-5, Gemini Ultra, Claude 3.7, Llama 4-Vision, Qwen-VL, and research models such as V-Jepa or MM1 are trained on massive corpora of images, videos, text, and sometimes audio—giving them a much broader understanding of the world.
This changes the game.
Not because they “see” better than vision models, but because they “understand” more.
2. Why Multimodal LLMs Are Gaining Ground
A. They excel at reasoning, not just perceiving
Traditional CV models tell you:
What object is present
Where it is located
What mask or box surrounds it
But multimodal LLMs can tell you:
What the object means in context
How it might behave
What action you should take
Why something is occurring
For example:
A CNN can tell you:
A multimodal LLM can add:
This jump from perception to interpretation is where multimodal LLMs dominate.
B. They unify multiple tasks that previously required separate models
Instead of:
One model for detection
One for segmentation
One for OCR
One for visual QA
One for captioning
One for policy generation
A modern multimodal LLM can perform all of them in a single forward pass.
This drastically simplifies pipelines.
C. They are easier to integrate into real applications
Developers prefer:
natural language prompts
API-based workflows
agent-style reasoning
tool calls
chain-of-thought explanations
Vision specialists will still train CNNs, but a product team shipping an app prefers something that “just works.”
3. But Here’s the Catch: Traditional Computer Vision Isn’t Going Away
There are several areas where classic CV still outperforms:
A. Speed and latency
YOLO can run at 100 300 FPS on 1080p video.
Multimodal LLMs cannot match that for real-time tasks like:
autonomous driving
CCTV analytics
high-frequency manufacturing
robotics motion control
mobile deployment on low-power devices
Traditional models are small, optimized, and hardware-friendly.
B. Deterministic behavior
Enterprise-grade use cases still require:
strict reproducibility
guaranteed accuracy thresholds
deterministic outputs
Multimodal LLMs, although improving, still have some stochastic variation.
C. Resource constraints
LLMs require:
more VRAM
more compute
slower inference
advanced hardware (GPUs, TPUs, NPUs)
Whereas CNNs run well on:
edge devices
microcontrollers
drones
embedded hardware
phones with NPUs
D. Tasks requiring pixel-level precision
For fine-grained tasks like:
medical image segmentation
surgical navigation
industrial defect detection
satellite imagery analysis
biomedical microscopy
radiology
U-Net and specialized segmentation models still dominate in accuracy.
LLMs are improving, but not at that deterministic pixel-wise granularity.
4. The Future: A Hybrid Vision Stack
What we’re likely to see is neither replacement nor coexistence, but fusion:
This is already common:
DETR/YOLO extracts objects
A vision encoder sends embeddings to the LLM
The LLM performs interpretation, planning, or decision-making
This solves both latency and reasoning challenges.
B. LLMs orchestrating traditional CV tools
An AI agent might:
Call YOLO for detection
Call U-Net for segmentation
Use OCR for text extraction
Then integrate everything to produce a final reasoning outcome
This orchestration is where multimodality shines.
C. Vision engines inside LLMs become good enough for 80% of use cases
For many consumer and enterprise applications, “good enough + reasoning” beats “pixel-perfect but narrow.”
Examples where LLMs will dominate:
retail visual search
AR/VR understanding
document analysis
e-commerce product tagging
insurance claims
content moderation
image explanation for blind users
multimodal chatbots
In these cases, the value is understanding, not precision.
5. So Will Multimodal LLMs Replace Traditional CV?
Yes for understanding-driven tasks.
No for real-time and precision-critical tasks.
Most realistically they will combine.
A hybrid model stack where:
CNNs do the seeing
LLMs do the thinking
This is the direction nearly every major AI lab is taking.
6. The Bottom Line
The future is not “LLM vs CV” but:
- Vision models + LLMs + multimodal reasoning ≈ the next generation of perception AI.
- The change is less about replacing models and more about transforming workflows.
