2004, The Year of the Angry Earth. AKA The year of the monkey

What do 1906 and 2004 have in common. Simon Winchester tells us in his NYT column, The Year the Earth Fought Back

LIKE two bookends of calamity, earthquakes at Bam in Iran and off Sumatra in Indonesia have delineated a year of unusual seismic ferocity - a year, one might say, of living dangerously. Twelve months, almost to the very hour, before Sunday's extraordinary release of stress at the India-Burma tectonic plate boundary, a similar jolt at the boundary of the Arabian and the Eurasian Plates devastated one of the most celebrated of Persian caravan cities. The televised images of Bam's collapsed citadel and the sight of thousands of bodies being carried from the desert ruins haunted the world then just as the images of the drowned around the shores of the Bay of Bengal do today.
But that has not been the half of it. True, these two disasters were, in terms of their numbers of casualties, by far the most lethal. But in the 12 months that separated them, there have been many other ruinous and seismically ominous events, occurring in places that seem at first blush to be entirely disconnected.

This year just ending - which the all-too-seismically-aware Chinese will remind us has been that of the Monkey, and so generally much prone to terrestrial mischief - has seen killer earthquakes in Morocco in February and Japan's main island of Honshu in October. The Japan temblor left us with one widely published image - of a bullet-train, derailed and lying on its side - that was, in its own way, an augury of a very considerable power: no such locomotive had ever been brought low before, and the Japanese were properly vexed by its melancholy symbolism.

In America, too, this year there have been some peculiar signs. Not only has Mount St. Helens been acting up in the most serious fashion since its devastating eruption of May 1980, but on one bright mid-autumn day in California this year the great San Andreas Fault, where the North American and Pacific Plates rub alongside one another, ruptured. It was on Sept. 28, early in the morning, near the town of Parkfield - where, by chance, a deep hole was being drilled directly down into the fault by geologists to try to discern the fault's inner mysteries.

That's 2004, so what about 1906?

As every American schoolchild knows, the most notorious rupture of this same fault occurred nearly a century ago, at 5:12 a.m. on April 18, 1906 - an occurrence now known around the world as the great San Francisco Earthquake. An entire city, a monument to the hopes and dreams of America's westward expansion, was destroyed by a mere 40 seconds of shaking. It was an occurrence possessed of a historical significance that may well be matched by the tragedy now unfolding on the far side of the world.

But, curiously, it turns out that there were many other equally momentous seismic events taking place elsewhere in the world in 1906 as well. Ten weeks before the San Francisco quake there was one of magnitude 8.2 on the frontier between Colombia and Ecuador; then on Feb. 16 there was a violent rupture under the Caribbean island of St. Lucia;then on March 1, 200 people were killed by an earthquake on Formosa; and then, to pile Pelion upon Ossa, Mt. Vesuvius in Italy erupted, killing hundreds.

But even then it wasn't over. The grand finale of the year's seismic upheaval took place in Chile in August, a quake that all but destroyed the port of Valparaiso. Twenty thousand people were killed. Small wonder that the Chinese, who invented the seismograph and who tend to take the long view of all historical happenings, note in their writings that 1906 was a highly unusual Year of the Fire Horse, when devastating consequences are wont to abound, worldwide.

Is this too much to be a coincidence? Perhaps, unfortunately Mr Winchester opts to try to explain it using the quasi spiritual Gaia Theory of James Lovelock. Although there is little doubt the planet is like a finely balanced machine where each part has the potential to impact every other the Gaia Theory goes too far when it suggests that the entire planet is a living organism. We would be better served to look at other factors. Was there anything unusual about the effect of the moon and the sun on the earth in the last 12 months? The tidal effects caused by the moon, and too a lesser extent the sun, are easy for us to see in the water of the ocean but impact the entire planet. The distance of the sun and the moon are not constant. At times they work together and at other times work against each other. Extreme high tides and low tides in the oceans are the result. And yes, although we don't see them the rocks have tides too.
