Detecting Ancient Earthquakes

Scientists have a new tool which will allow them to study earthquakes of the past. this will aid them in helping to leanrand predict earthquakes. "Using the basic principles of friction, the researchers considered the geometry of the shapes they found in the Dead Sea sediment and combined it with a number of other parameters found in physical science to calculate how earthquakes from the past were distributed in scale, time and place. "the quote, taken from the article helps give some knowledge on how the tool works, which is more helpful to somebody like me with little understanding of how it works.

Drillers propose deep-Earth quest.

Off the coast of Costa Rica, scientists are panning on trying to unearth the deepest rock samples of the ocean. The scientists do have samples that have been brought up by mountains or lava flow from volcanoes, but each has been tampered with in a way that makes them impure. the reason to try it in the ocean is that going through from the ocean is less, a lot less, to drill though.

Deep-sea volcanoes don't just produce lava flows, they also explode

It is well known that volcanoes under water produce magma and lava frequently. 80% of all volcanic activity is caused under the sea level.but until recently, it has been unknown wether or not they erupt. a PhD student found crystals containing very high CO2 levels in the magma trapped inside of the crystals.this represents magma in a state prior to eruption,which proves eruption can occur.
