Why earthquake did not cause a tsunami

Why earthquake did not cause a tsunami | Plate Tectonics and Associated Hazards | Scoop.it

At a magnitude of 8.6, yesterday's earthquake off the Indonesian province of Aceh was one of the largest ever recorded.Yet the massive tremor, which was followed by an 8.2-magnitude aftershock, did not cause a severe tsunami such as the one on December 26, 2004, which devastated countries around the Indian Ocean and killed more than 200,000.

 

So what is the difference?

Stunning Map Reveals World's Earthquakes Since 1898

Stunning Map Reveals World's Earthquakes Since 1898 | Plate Tectonics and Associated Hazards | Scoop.it

If you've ever wondered where — and why — earthquakes happen the most, look no further than a new map, which plots more than a century's worth of nearly every recorded earthquake strong enough to at least rattle the bookshelves.

 

The map shows earthquakes of magnitude 4.0 or greater since 1898; each is marked in a lightning-bug hue that glows brighter with increasing magnitude.

 

The overall effect is both beautiful and arresting, revealing the silhouettes of Earth's tectonic boundaries in stark, luminous swarms of color. 

 

The map's maker, John Nelson, the user experience and mapping manager for IDV Solutions, a data visualization company, said the project offered several surprises.

 

"First, I was surprised by the sheer amount of earthquakes that have been recorded," Nelson told OurAmazingPlanet. "It's almost like you could walk from Seattle to Wellington [New Zealand] if these things were floating in the ocean, and I wouldn't have expected that."

 

In all, 203,186 earthquakes are marked on the map, which is current through 2003. And it reveals the story of plate tectonics itself.

 

The long volcanic seams where Earth's crust is born appear as faint, snaking lines cutting through the world's oceans. The earthquakes along these so-called spreading centers tend to be rather mild. The best studied spreading center, called the Mid-Atlantic Ridge, bisects the Atlantic Ocean, on the right side of the image.

 

Its Pacific counterpart wanders along the eastern edge of the Pacific Ocean, cutting a wide swath offshore of South America. Another spreading center makes a jog though the Indian Ocean and up through the Red Sea.

But one glance at the map shows that the real earthquake action is elsewhere. Subduction zones, the places where tectonic plates overlap and one is forced to dive deep beneath the other and into the Earth's crushing interior — a process that generates the biggest earthquakes on the planet — stand out like a Vegas light show.

 

Nelson said this concept hit home particularly for the Ring of Fire, the vast line of subduction zones around the northern and western edge of the Pacific Ocean.

 

"I have a general sense of where it is, and a notion of plate tectonics, but when I first pulled the data in and started painting it in geographically, it was magnificent," Nelson said. "I was awestruck at how rigid those bands of earthquake activity really are."
