The Earth Breathes Fire

 

Continuing the journey into the mysterious Earth

“Aaba,” Mihir said, “why do people suddenly burst out like that?”

The soft clicking from Aaba’s laptop stopped mid-move. Bridge could wait.
“Why?” Aaba asked gently. “What happened?”

“On the bus today… that boy who never talks much—he just burst,” Mihir explained. “I didn’t see exactly what happened, but maybe someone bullied him.”

Aaba nodded slowly. “Long quiet,” he said thoughtfully. “Then release.”
He looked at Mihir. “If the Earth did that, where would it happen?”

Mihir grinned. “You never miss a chance to turn a conversation into geology. Do you?” He paused. “Anyways, let me guess. Earthquakes?” Then, quickly, “Volcanoes?”

Aaba smiled. “Yes. And volcanoes,” he said, “are where the Earth lets its fire speak.”

He leaned back slightly and added, “But that fire doesn’t appear on its own. It’s tied to how the Earth itself moves.”

“You mean the plates,” Mihir said.

“Exactly,” Aaba replied. “You remember what we talked about earlier. The Earth isn’t one solid block. It’s broken into enormous plates that drift slowly over time.”

“And it’s the heat inside the Earth that makes them move,” Mihir said, thinking aloud.

Aaba nodded. “Good. Then tell me—can you recall the layers that make up the Earth?”

“Yes,” Mihir said. “The outermost layer is the crust—thin and fragile. Beneath it lies the mantle—vast and hot. And deeper still is the core, a powerful source of heat that keeps the Earth restless.”

Aaba smiled. “That’s right, Mihir. You are a very good learner.” He paused, then continued. “Volcanoes are what happen when that heat, that movement, and a lot of pressure finally find a way out.”

Mihir leaned forward. “Through cracks?”

“Through weak spots,” Aaba replied. “Places where the Earth is stretched, squeezed, or simply tired of holding things in.”

Deep within the mantle, he explained, most rock remained solid. But in certain places, under the right heat and pressure, small portions of it melted into something thick, glowing, and heavy. This molten rock, called magma, did not rush upward like water. Most of the time, it stayed trapped below, gathering slowly in pockets known as magma chambers.

“What makes it move then?” Mihir asked.

“Space,” Aaba said. “And weakness.”

 When plates shifted—sometimes pulling apart, sometimes pressing together—they created zones where the crust was thinner or strained. Magma is more likely to rise through such weak zones. It does so slowly and steadily.

“That,” Aaba said, “is how most volcanoes are born. Quietly at first. With pressure building over time.”

Mihir nodded. “So, volcanoes aren’t random holes in the ground.”

“Hmmm…” Aaba said, leaning back. “Often, they follow patterns. But the Earth doesn’t always behave neatly.”

Sometimes, he explained, the heat rose from deep below even when plates were not colliding or pulling apart. A stubborn column of heat pushed upward from the mantle, staying in one place while the plate above slowly drifted over it.

“These places,” Aaba said, “are called hot spots. The plate moves. The heat stays.”

“Some of the world’s most famous volcanoes were born this way,” Aaba continued.

He asked Mihir if he had heard of Hawaii. Mihir nodded at once. “The islands,” he said. “With beaches and volcanoes.”

“Exactly,” Aaba said. “Hawaii sits over a hot spot. The heat stays in one place, deep below, while the Pacific Plate above it slowly moves on. Each time the plate shifts, a new volcano forms. Together, they create a trail—each island marking a place where the Earth once broke through.”

Mihir looked amused. “That’s interesting,” he said. “Mama took Eiaa and Evee there for a holiday last year. I’ll ask them if they know what they visited.” Mischief was unmistakable in his tone.

Mihir was about to speak when Aaba added, “And much closer to home, India carries its own hot-spot story.”

He explained that long before the Himalaya began to rise, vast lava flows poured out across western India. Layer upon layer of molten rock spread and cooled, covering an enormous area.

“Those ancient eruptions,” Aaba said, “created what we now call the Deccan Traps.”

Mihir’s eyes widened. “Mumbai?”

“Yes,” Aaba replied. “Mumbai sits on those old lava flows. What’s fascinating is that the hotspot that fed those eruptions is now beneath the Réunion Islands, far to the south, because the Indian plate has moved on.”

Turning to the present, Aaba continued “Volcanism isn’t something that happened once and stopped,” he said. “It’s happening all the time.”

He told Mihir about Indonesia, a country sitting on some of the most restless ground on Earth. “Mount Semeru,” he said, “has erupted repeatedly in recent times—several times in a single day as recently as just a few days back.” Ash rose into the sky, and thick flows of mud rushed down the slopes.

“Mud?” Mihir asked. “Not lava?”

“That’s the trick,” Aaba said. “Volcanoes are not just about fire.” He explained how ash mixed with water and debris to form powerful mudflows that moved faster than people expected.

Then Aaba spoke of Ethiopia, where a volcano that had slept through thousands of years awakened as recently as a few days back. Ash rose high into the atmosphere. Flights were cancelled far away. People who had lived their entire lives near the volcano realised that silence did not mean safety.

“How do scientists even know it was asleep for that long?” Mihir asked. “There were no people to watch it.”

Aaba explained that volcanoes left behind layers—ash, lava, rock—stacked like pages in a book written slowly over time. By reading those layers, scientists could tell which eruptions were recent and which belonged to deep prehistory. Even long silence left a trace.

For a while, neither of them spoke. The laptop sat forgotten. The room felt calm again.

Finally, Mihir said, “The Earth doesn’t lose its temper often, does it?”

“No,” Aaba said. “But when it does, it leaves clues everywhere.”

Mihir grinned. “You talked about volcanoes like they’re alive. So, tell me—where are the most fascinating ones in the world? The kind people go to see. Maybe I can convince Dad that our next holiday won’t be just a holiday, it would be a funeducational holiday.”

Aaba laughed. “That,” he said, “may be the best definition I’ve heard.”

Aaba settled back, just for a moment. “Well,” he said, “if you want to see where the Earth is most restless, you’d start with something called the Ring of Fire.” He explained that it was not a single volcano, but a vast belt circling the Pacific Ocean, where plates constantly meet, slide, and sink. Indonesia, Japan, parts of the Americas—many of the world’s most active volcanoes lived along this restless rim.

“That sounds dangerous,” Mihir said.

“It can be,” Aaba agreed. “But it’s also fascinating. People live there, study the volcanoes, and learn to respect them.”

Then he smiled. “But not all famous volcanoes are angry.”

He told Mihir about Mount Fuji in Japan—quiet, symmetrical, and deeply loved. It had not erupted for centuries, yet people from all over the world climbed it, painted it, photographed it, and wrote poems about it. “Fuji,” Aaba said, “reminds us that a volcano doesn’t need to erupt to be powerful.”

He mentioned Mount Etna in Italy, still active, sometimes puffing smoke gently, sometimes glowing at night, while towns and vineyards thrived on its fertile slopes. And then there were places like Yellowstone, where the heat stayed hidden underground, showing itself through hot springs and geysers instead of lava.

“So, volcanoes don’t all look the same,” Mihir said.

“No,” Aaba replied. “Some shout. Some whisper. Some simply wait.”

 Mihir leaned back, imagining it all. “Okay,” he said. “Next holiday, I’ll suggest a quiet volcano. One that behaves.”

Aaba laughed as he stood up. “A wise choice,” he said. “You could start with Mount Bromo in Indonesia—dramatic, but polite enough for visitors. Mayon in the Philippines is another beauty, though it likes reminding people who’s in charge.” He paused, then added, “And if you want to end on a calm note, Mount Fuji in Japan. A volcano that teaches patience—and lets you experience the culture of some of the most courteous and disciplined people in the world.”

With that, the laptop clicked back to life. Mihir gathered his books, but his mind stayed elsewhere wandering across oceans, mountains, and quiet peaks where the Earth’s fire slept just below the surface.

As the clicking resumed, Mihir smiled to himself. The Earth, he realised, behaved a lot like people—quiet, patient, and occasionally impossible to ignore.
