Krakatoa: The Day the World Exploded: August 27, 1883 - Simon Winchester (2003)



He also had one volcano that was extinct. But, as he said, ‘One never knows!’ So he cleaned out the extinct volcano, too. If they are well cleaned out, volcanoes burn slowly and steadily, without any eruptions. Volcanic eruptions are like fires in a chimney.

On our earth we are much too small to clean out our volcanoes. That is why they bring no end of trouble upon us.

– from The Little Prince by Antoine de Saint-Exupéry, 1944

It was early on a warm summer's evening in the 1970s, as I stood in a palm plantation high on a green hillside in western Java, that I saw for the first time, silhouetted against the faint blue hills of faraway Sumatra, the small gathering of islands that is all that remains of what was once a mountain called Krakatoa.

There was a high peak to the left of the group, its pyramid shape cut off sharply by its vertical northern cliff. A couple of low islands hugged the horizon to the right. In between them was one small and perfectly formed, absolutely symmetrical low cone, from which rose a thin wisp of smoke. The smoke left a blackish, greyish trail that first rose vertically and then, as it caught the trade winds a few hundred feet above the darkening surface of the sea, was whisked off to the left, melting away until it became no more than a slow-fading stain against the salmon glow of the sunset.

I must have stood there, enraptured, until it got quite dark. And then I turned away for the drive back to Jakarta. This, I remembered thinking during the endless night of the flight back west, had been a scene of impeccable beauty. And all the more so because it presented a distant prospect of a place where the processes of the world were at work, a place of elemental significance, and a disastrous place once – but these days quiet again, serenely biding its time.

It was almost another quarter of a century before I found myself back in Java. Most of the work I was doing now kept me in the island's centre, in towns like Jogjakarta and Solo and Semarang. But just before I was due to fly away, and because I had a free evening until my plane left, I decided on a whim to make my way back across to the western edge of the island. I drove down to the coast road, just as I had in the seventies.

I wanted to go back for no other reason than to take what I thought would be one final look at a place that, though few beyond the East Indies knew exactly where it was or what it looked like or just what had happened there, had a name – Krakatoa – that had for decades been firmly annealed into the world's collective consciousness. There was a famous film (which admittedly placed the island on the wrong side, the east side, of Java). There was a much loved children's book (which admittedly placed the island in a different ocean, the Pacific, rather than in the Indian). The name had become part of the world's cultural lexicon – it had a vaguely exotic familiarity about it, a certain indefinable resonance. It was a word that people seemed to like, both to say and to have said to them. And now here I was, so close to the volcano that the chance of seeing it once more seemed an opportunity that I shouldn't pass up.

When I reached the best viewpoint on the corniche, it was evening, perhaps a little later than before, and so rather darker than when I had been there last. This time the enormous iron lighthouse near the port of Anjer – built by the Dutch to replace the one that had been torn away in the terrible waves caused by the great eruption – was sweeping its beam calmly across the unruffled waters of the Sunda Strait, beginning its night on sentry-go.

The group of islands was there, just as before, now black against the vivid deep pinks of the western sky. The giant peak to the left of the group was just as I remembered; the low islands too, this time merging with the evening clouds. And in the middle of them all, its summit seemingly lipped with a curious orange fire, rose the pyramid-shape of the one active remnant of the great disaster. As I looked through my glasses, I could clearly see that the orange was indeed fire, and that from it rose smoke, just as before, only this time a tumble of black billows that towered straight up into the windless late-evening sky.

But there was one obvious difference. The pyramid – which I now knew to be called Anak locally, which is Malay for the child of what had once existed there before the great eruption – seemed this time somehow bigger, sturdier, much taller than I had remembered.

I blinked hard, looked again. I measured it as best I could against the big peak to the left – trying to recall where the smaller mountain had stood in relation to that cliff wall. It was higher up now, surely. Yes, there was no doubt. Memory does play tricks in situations like this, to be sure: but, as I stared long and hard, I became ever more certain. The volcano, the child of Krakatoa, had grown very much larger during the twenty-five years that I had been away.


When I got back to the maps, I checked, and could see in short order that the modern surveys all agreed. The small island-mountain, which had been born out of the sea forty-odd years after the very explosion that destroyed and vaporized its parent, was now itself growing fast, thrusting upwards at an extraordinary rate. By looking at the old charts and maps that had been published down the years since the last week of June 1927, when it was first seen above the waves, it was possible to calculate that it had been growing taller, fairly steadily, at an average rate of about five inches a week.

True, there had been some fits and starts – a lava flow here, a wild eruption there – but generally Anak Krakatoa had enlarged itself by twenty or so inches each month since 1927. Every year since its birth it had become higher by twenty feet, and somewhere near forty feet wider. And if this was indeed still so – I checked my figures once again – then it meant that my mountain was not simply taller: it was fully five hundred feet taller than when I had last seen it.

Which is why this sturdy stripling of a volcano has captivated me ever since. It is a volcano that absolutely and very visibly refuses to die. It is a volcano that seems to me to possess a wonderfully seductive combination of qualities, being beautiful and dangerous, unpredictable and unforgettable. And more: though what happened in its former life was unutterably dreadful, the realities of geology and seismicity and the peculiar tectonics of Java and Sumatra will make sure that what occurred back then will without a doubt one day repeat itself, and in precisely the same way.

No one can be sure exactly when. Probably it will be very many years – many years, that is, before anything will befall the world that could possibly be as terrible as what took place during the historic paroxysmal moment that reached its extraordinary climax at exactly two minutes past ten on the morning of Monday, 27 August 1883.


The explosion itself was terrific, a monstrous thing that still attracts an endless procession of superlatives. It was the greatest detonation, the loudest sound, the most devastating volcanic event in modern recorded human history, and it killed more than 36,000 people.

Geological evidence from around the world admits of a number of bigger and more devastating volcanoes, true. Krakatoa is reckoned today to be only the fifth most explosive in the planet's certain geological history – Mounts Toba and Tambora in the East Indies, Taupo in New Zealand and Katmai in Alaska are all thought to have been very much larger, at least in terms of the amount of material they hurled into the sky and the height to which all that material is thought to have soared.

But these were all eruptions quite lost to antiquity, with rather little direct effect on human society. When Krakatoa exploded it was 1883, and the world was a profoundly different place. Sophisticated human beings were on hand to see this volcano's convulsions, they were able to investigate the event, and they were able to attempt to understand the processes that had caused such dreadful violence. And yet, as it happens, their observations, painstaking and precise as science demanded, collided head on with a most discomfiting reality: that while in 1883 the world was becoming ever more scientifically advanced, it was in part because of these same advances that its people found themselves in a strangely febrile and delicately balanced condition, which an event like Krakatoa did much to unsettle.

The communications technology of the time, for example – the advances of telegraphy, the building of undersea cables, the flourishing of news agencies – ensured that the world's more advanced peoples learned about the eruption within moments of its happening. But at the time the limited, and only slowly unfolding, geological knowledge then to hand did not give the audience an explanation of the events that was sufficient to soothe their fears about all they were learning. Hearing of the event baffled people thousands of miles away from where it happened, and left faraway populations bewildered and, in some cases, more than a little frightened.

Moreover, religious dogma still held a powerful grip on millions, even in societies whose scientific understanding was advancing so rapidly. Tribal ancestors might have explained away an eruption like Krakatoa's: it was simply a matter of the gods being angry. But the luxury of such a facile explanation was not available to the more modern people of 1883, whose growing sophistication meant they both knew so much about an event like this and yet at the same time actually knew so little. They had sufficient knowledge of the facts – the news agencies saw to that – but it was knowledge coupled with an insufficiency of understanding. Many people worried in consequence that the eruption of Krakatoa meant something infinitely more dreadful than it did: that their world was being torn asunder, and perhaps even, as the Bible had foretold, was coming to an end.

Fretful and fascinated people around the world, in cities as distant from Java and from each other as Boston and Bombay and Brisbane, all came to know of the event in an instant – and they did so quite simply because this was the world's first major catastrophe to have taken place in the aftermath of the invention of the submarine telegraph. The newspapers were full of it, the descriptions of the happenings made all the more enthralling because they were so perfectly up to date. Words and phrases that had hitherto been utterly unfamiliar – Java, Sumatra, the Sunda Strait, Batavia – became in one mighty flash of eruptive light part of the common currency of all.

And in learning of these places and of the terrible events that occurred there, so the world's people suddenly became part of a new brotherhood of knowledge – in a sense it was that day in August 1883 that the modern phenomenon known as the global village was born, in part through the agency of this enormous explosion. The word Krakatoa, despite being a word misspelled and mangled by the imperfect arts of Victorian telegraphy and journalism, became in one awful ear-splitting moment a byname for cataclysm, paroxysm, death and disaster. And the disaster left a trail of practical consequences – political, religious, social, economic, psychological, scientific consequences among them. Even today curious and chilling echoes of those consequences are still faintly and worryingly discernible, both in Java and around the globe.

In all sorts of other observable ways the impact of Krakatoa on the world's consciousness was profound, and immensely more so than in the case of the eruption of the four technically greater volcanoes of earlier times. Krakatoa had an impact on climate, for example: the airborne debris hurled into the skies lowered the planet's temperature; it changed the appearance of the entire world's sky; it set barometers and tide-meters to flailing wildly thousands of miles away; it panicked American firefighters into battling what they thought were raging infernos, but that were in truth violent sunsets caused by the roiling clouds of Krakatoan dust.

Because of all the painstaking and precise work that was begun in the immediate aftermath of the eruption, we know today just why it was that Krakatoa erupted, and we understand only too well the nature of the forces that caused it. An entirely new science has come along to pare away the old and myth-making mysteries of the event, and to render this volcano, and indeed all other volcanoes, readily explicable.

Now, from a palm plantation high on a green hillside, Krakatoa looks peaceful and serene, with just a thin column of white or grey or on occasion black smoke easing up from its summit. But looks are deceptive: all the while the child-mountain is growing steadily and rapidly, as the elemental fires that created the world rage deep inside.
