Experience the sound of a powerful Earthquake

Strong Motion seismometer that measures accele...

Thanks to the great service of USGS, we are able to share the sound of a couple of earthquakes to our readers.
As every earthquake has it’s own fingerprint, the sound  going together with it can be seriously different.  Depending on the  Magnitude, rock material, fault lines, etc. the frequency can be low or high and the sound can be short or rolling.

It may be easier to hear the small triggered earthquakes than it is to see them. The Landers earthquake is far from the seismometer so most of its high frequencies have died away before the waves reach the seismometer. But the small earthquakes have small fault areas and therefore produced high frequency energy and because they are near the seismometer this energy has not died away.

Listen to the seismogram recorded at the Long Valley Caldera and see if you can hear the small earthquakes (high frequency bursts) despite the low rumble of the distant large earthquake. Click the sideways triangle (or play button) to hear the sound.

If you are having trouble picking out the small nearby earthquakes, listen for the two very close to the end and then listen to the seismogram again.

Here are two more seismograms of the Landers earthquake. One is recorded at Parkfield near Paso Robles and the other is recorded at the Geysers north of San Francisco. Only one of these areas had small earthquakes triggered by the Landers event. Can you tell which one?

Serbia, Kraljevo : race against the time to repair houses +volunteers needed

Race against the clock as winter is coming soon.

Damage in Kraljevo, Serbia - Picture courtesy EMSC

Excerpt from Serbias newssite B92
Many Kraljevo residents work to repair their homes even during the night, fearing heavy rainfall, while aftershocks (although weaker and weaker) are continuing to strike the greater Kraljevo area.
The 5.6-magnitude quake hit the town early on November 3, killing two people and leaving thousands of homes either damaged or destroyed.

A commission is currently working to determine which damaged structures have been rendered uninhabitable, but the number will ber  likely approx. 1,000.

Thus far, 13,000 buildings have been reported as unsafe, and the commission has appealed on skilled staff, including engineers, to join them in order to complete the job as soon as possible.
Help is arriving to Kraljevo, but the town needs more volunteers and trucks to transport building material.
Some of the families will likely have to be housed in prefab homes, said reports.

“In memory of” is highlighting deadly earthquakes of the past.
People have forgotten a lot of these human tragedies.
We @ Earthquake Report are hopeful that people in these countries and cities will learn from their history and will make sure that they are building Earthquake Proof houses and that they know what to do when the earth will be shaking again.
