Chersky Range in the context of "Bering Land Bridge"

The Eurasian plate is a tectonic plate that includes most of Eurasia (a landmass consisting of the traditional continents of Asia and Europe), with the notable exceptions of the Arabian Peninsula, the Indian subcontinent, and the area east of the Chersky Range in eastern Siberia. It also includes oceanic crust extending westward to the Mid-Atlantic Ridge and northward to the Gakkel Ridge.

Beringia is a prehistoric geographical region, defined as the land and maritime area bounded on the west by the Lena River in Russia; on the east by the Mackenzie River in Canada; on the north by 72° north latitude in the Chukchi Sea; and on the south by the tip of the Kamchatka Peninsula. It includes the Chukchi Sea, the Bering Sea, the Bering Strait, the Chukchi and Kamchatka peninsulas in Russia as well as Alaska in the United States and Yukon in Canada.

The area includes land lying on the North American Plate and Siberian land east of the Chersky Range. At various times, it formed a land bridge referred to as the Bering land bridge or the Bering Strait land bridge that was up to 1,000 km (620 mi) wide at its greatest extent and which covered an area as large as British Columbia and Alberta together, totaling about 1.6 million km (620,000 sq mi), allowing biological dispersal to occur between Asia and North America. Today, the only land that is visible from the central part of the Bering land bridge are the Diomede Islands, the Pribilof Islands of St. Paul and St. George, St. Lawrence Island, St. Matthew Island, and King Island.

The North American plate is a tectonic plate containing most of North America, Cuba, the Bahamas, extreme northeastern Asia, and parts of Iceland and the Azores. With an area of 76 million km (29 million sq mi), it is the Earth's second largest tectonic plate, behind the Pacific plate (which borders the plate to the west).

It extends eastward to the seismically active Mid-Atlantic Ridge at the Azores triple junction plate boundary where it meets the Eurasian plate and Nubian plate.and westward to the Chersky Range in eastern Siberia. The plate includes both continental and oceanic crust. The interior of the main continental landmass includes an extensive granitic core called a craton. Along most of the edges of this craton are fragments of crustal material called terranes, which are accreted to the craton by tectonic actions over a long span of time. Much of North America west of the Rocky Mountains is composed of such terranes.

The Laptev Sea Rift is a divergent tectonic plate boundary between the North American Plate and the Eurasian Plate located on the Arctic Ocean coast of northeastern Siberia in Russia. The Laptev Sea Rift is the continuation of the Gakkel Ridge (Mid-Arctic Ridge) into the continental crust of Siberia. It starts offshore in the continental shelf and continues onshore to a point located in the Chersky Range where the boundary motion changes from extension to compression.

The Ulakhan Fault is a left-lateral transform fault that runs along the boundary between the North American plate and the Okhotsk microplate in northeast Asia. It runs from a triple junction in the Chersky Range in the west, to another triple junction with the Aleutian Trench and the Kuril Trench in the east. From the offset of dated geomorphological features, a slip rate of 5.3±1.3 mm per year has been measured, consistent with estimates from GPS-constrained global plate models. The analysis of fault scarps along the fault zone in the Seymchan Basin suggests that the fault is characterised by occasional large (M_w>7.5) earthquakes.
