A schematic block model of Southern California showing the motion of the Pacific and North American plates, and the big bend of the San Andreas fault where the plates squeeze together. Fault system off San Diego, Orange, Los Angeles counties … Continue reading
The fault beneath Ventura, California, would probably trigger stronger shaking throughout an earthquake and extra injury than beforehand suspected, researchers warn. The Ventura-Pitas Point fault in Southern California has been the main target of a lot current consideration as a … Continue reading
Researchers believe the quakes could be caused by pieces of the Earth’s mantle breaking off and sinking into the planet in the affected area (shown here). They say pieces of the mantle have most likely been breaking off from underneath … Continue reading
A new mechanism may explain how great earthquakes with magnitudes larger than M7 are linked to coastal uplift in many regions worldwide. This has important implications for the seismic hazard and the tsunami risk along the shores of many countries. … Continue reading
Flight of marine terraces on the south coastline of Crete, Greece, eastern Mediterranean. The lower prominent paleoshoreline (indicated by the red-line) records tectonic rock uplift during the 365 AD M>8 earthquake. The higher marine terraces (indicated by the yellow-lines) record … Continue reading
A lab made quasicrystal. The rarest crystals on Earth: Scientists reveal only two quasicrystals have EVER been found – and they were caused by colliding asteroids Naturally formed quasicrystals?crystal-like solids with supposedly impossible symmetries?are among the rarest structures on Earth. … Continue reading
Bubbly syrup reveals how earthquakes shake up volcanoes – Snapshots of the same box, filled with a green syrup as well as bubbles and plastic flakes (grey color), used to study magma in volcanoes. Researchers place the box on top … Continue reading
