From what I’ve read, this is what happens: The lithosphere is composed of many tectonic plates. When these plates push up against on another due to the force of convection currents in the underlying mantle, pressure builds up until it reaches a breaking point and energy in the form of seismic waves (aka earthquakes) is produced.

Please let me know if this is correct or not! Thanks!

I need this for a project. How do cities prepare and protect against earthquakes? Not an individual, cities. For example, shock absobers, or things that lessen damage, or help to see it coming.

i get that like they detect vibrations but do scientist set up sensors around the earth? how else could the machine detect earthquakes all over the world?

tsunami warning with it…. are you folks who are nearby or on shorelines getting out , NOW????>…. please do…..

report not considering the tsunami, if one is generated, to be too dangerous…. ok…. sorry… you don’t have to run for the hills…. but… I’d stay aware, anyway…..can’t be too careful, right?…..
still, there WAS a tsunami… people were lost…. the warning should have remained….very sad….

A) The Richter scale allows us to make predictions of earthquake damage.
B) Each step of the scale represents a 30-fold increase in energy released.
C) The Richter scale measures the magnitude of an earthquake.
D) Earthquakes with equal ratings do not have the same damage.

No intention to cause controversy here, I mean this as a serious question. The featured article the other day was about how Hilary Clinton seems to be "causing" earthquakes during her trips abroad, so I wasn’t sure if this was supposed to be a comical blog akin to a conservative spin on The Daily Show, or more aligned with his Fox News and radio shows. I don’t watch Glenn Beck frequently enough to know if he has a comic relief segment in his show. Some of the articles on the Blog seems much more serious than others.

I am curious what kind of energy is created from earthquakes, and if a mountain absorbs some of the energy, what is this process called? Also what is the energy be called that the mountain absorbs?

If one earthquake has a magnitude of 5 on the richter scale and a second earthquake has a magnitude of 6 compare the intensities of the two earthquakes.

I know this has something to do with logarithims and the answer is 60 DB, I just dont know how to arrive at the answer, thanks.

a problem in my physics book went something like this
Earthquakes produce Pwaves and Swaves. Pwaves have a constant velocity of 8km/s and Swaves have constant velocity of 6km/s. If a station records Pwaves and 33seconds later records Swaves, how far away was the earthquake??

What are some famous Earthquakes and volcanic eruptions?
Could i have a list.
thanks
