Environment Updates: Earthquakes, Air Pollution & Everyday Tips

Welcome to the environment hub of PC Literacy Info. Here you’ll find straight‑forward info about what’s shaking the ground and what’s filling the air, plus clear steps you can take right now. No jargon, just what matters for you and your family.

Why the Delhi Earthquake Felt So Strong

On February 17, 2025, Delhi experienced a 4.0‑magnitude quake that many thought would be barely noticeable. Instead, high‑rise buildings swayed, glass cracked, and people rushed out of offices. The surprise came from three simple factors:

• Epicenter inside the city: The quake’s source was right in the urban area, so the shaking didn’t have to travel far before hitting you.
• Very shallow depth: When tremors occur just a few kilometres below the surface, the energy reaches the surface with little loss.
• Geology of the region: Delhi sits on soft alluvial deposits that amplify seismic waves, making even modest quakes feel intense.

Because of these reasons, buildings that usually sway only a little showed visible movement. The immediate advice? Keep a flashlight, a phone charger, and a small emergency kit near your desk. If you’re in a high‑rise, stay away from windows and follow the building’s evacuation plan. The quake was moderate, but the experience taught many residents to treat any shaking seriously.

Air Pollution: Real Impacts and How to Protect Yourself

While the ground shook in Delhi, the air across India has been choking many of us. Tech entrepreneur Bryan Johnson recently walked off a podcast because his skin broke out from the smog. His story isn’t unique – millions inhale particulate matter (PM2.5) that can irritate eyes, lungs, and even skin.

What can you do right now?

• Check the AQI: Use a free app or website to see the air‑quality index. When it’s above 150, limit outdoor activities.
• Mask up: A certified N95 or KF94 mask filters out most particles. Keep one in your bag for sudden spikes.
• Indoor air tricks: Close windows, run an air purifier, or place a bowl of water near vents to capture dust.
• Stay hydrated: Drinking water helps your body clear out pollutants faster.

Long‑term, planting trees, supporting clean‑energy policies, and using public transport can lower the overall pollution levels. Every small action adds up, just like each tremor added up to a noticeable shake in Delhi.

Both the earthquake and the air‑quality crisis remind us that the environment can change fast, and staying informed is the best defense.
