Fracture zones refer to areas on the Earth's surface where the crust has been broken or fractured. These zones can occur along the boundaries of tectonic plates and are often associated with tectonic activity, such as earthquakes and volcanic eruptions. The fractures in these zones allow for the movement of tectonic plates, and can also lead to the formation of new landforms, like mountains and valleys.

The samples of ancient lava that they analyzed came from a heavily
fractured zone of crust between 351 and 583 meters below the sea floor a few hundred kilometers off the shore of Washington state.
The South American arc extends over 7,000 km, from the Chilean margin triple junction offshore of southern Chile to its intersection with the
Panama fracture zone, offshore of the southern coast of Panama in Central America.
Relicanthus sp. — a new species from a new order of Cnidaria collected at 4,100 meters in the Clarion -
Clipperton Fracture Zone (CCZ) that lives on sponge stalks attached to nodules.
When the drill bit encounters mineral veins or
other fracture zones in the peak ring, Cockell and his colleagues will take a subcore from the core: a biopsy on the geopsy.
The process squeezes Enceladus, ejecting jets of water from
large fracture zones near its south pole (pictured below).
The researchers collected the samples by boring a hole that tapped into the spring in a
deep fracture zone about 200 meters underground.
This debris, along with what is known as the
Shackleton Fracture Zone, has been shown in a recent study to be fairly young, only about 8 million years old.
AltaRock uses patented stimulation technology to create
new fracture zones adjacent to existing geothermal systems.
Dock - to - Dish fish selections are line - caught in a region 375 miles north of Oahu known as
the Fracture Zone, a region of the Pacific Ocean ideal for fishing this time of year.
Results have shown that the degree of locking in the western part of
the fracture zone is lower and that the two tectonic plates are creeping past one another at a very slow rate.
This is also supported by the fact that
the fracture zone of the last strong earthquake in the region, in 1999, ended precisely in this area — probably at the same structure, which has been impeding the progressive shift of the Anatolian plate in the south against the Eurasian plate in the north since 1766 and building up pressure.
