Seismic activity is to be expected in the Los Angeles region as the major hazard threat in the area.  This area has a great number of sensors which now allows us to visualize seismic waves better than ever before.  This video show 4 earthquakes (starting at 0:45, 2:20, 6:00, and 8:35).  For more information on the science behind this clip, read the adptly named blog, The Trembling Earth.

Myanmar's ancient temple city faces modern danger

Myanmar's ancient temple city faces modern danger | earthquakes | Scoop.it

he spires of Bagan have survived wars, earthquakes and centuries of tropical sun, but in recent years Myanmar's ancient capital has faced a distinctly modern threat -- scaffolding and cement.

The temples, some of which are around 1,000 years old, are one of the country's most treasured religious sites and a top attraction for foreign tourists flocking to the country as it emerges from decades of military rule.

While many have largely withstood the ravages of man and nature, haphazard renovation work has also seen new temples built on the foundations of crumbling structures, and experts say they bear little resemblance to the originals.

I found this scoop really interesting. Initially I didn't know where Myanmar was but, after doing some research I found out that it is a small country right next to Thailand. So this scoop mainly talks about these ancient temples in Myanmar that have been destroyed from erosion. So now the country is trying to rebulid these beautiful places with the constant fear of inadequate funds and random earthquakes.

Yet Another Study Confirms #Fracking Wastewater Wells Cause Earthquakes

Residents of Youngstown, Ohio didn’t even know what an earthquake felt like before the fracking industry came to town.

Jordan Meyer's curator insight, October 1, 2013 10:20 AM

Scientist believe that Fracking Wasetwater wells are causing earthquakes because of the "fluid injection" or pretty much the wasterwater getting shot into the ground because this is something they can't store above ground. It has caused over 100 earthquakes sense they have started using Fracking Wastewater Wells. They really don't even need these wells, they can find some other way to dispose of it by doing chemical research or something. So really it's their own fault and they know it's going to keep happening if they don't stop using them.

Causes of quakes

Is it possible for anything living to cause an earthquake?
— Megan


Yes, people can cause an earthquake through human activity. The most common way is by building a dam. It's very common to get small earthquakes after filling a dam, firstly because of the extra load due to the weight of the water; and then secondly because water seeping down into faults can cause them to move if they're at breaking point. Liquid acts as a lubricant enabling faults to slide more easily.

 

Another way humans can cause earthquakes is with mining - taking material out of the ground also causes little stresses which can results in earthquakes.

 

Pumping oil out can cause earthquakes by changing the stresses underground or because water pumped down to flush the oil out can have a lubricating effect.

 

Another human-related cause of earthquakes is when water is pumped through hot rocks several kilometres underground in order to harness geothermal energy. This can cause little tremors, up to magnitude 3 on the Richter Scale. Scientists use these small earthquakes to trace what is happening underground - they can follow exactly where the water is by following the little earthquakes.

Stunning Map Reveals World's Earthquakes Since 1898

Stunning Map Reveals World's Earthquakes Since 1898 | earthquakes | 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."
