Earthquake epicenters 1963–98. In seismology, a seismic zone or seismic belt is an area of seismicity potentially sharing a common cause. It can be referred to as an earthquake belt as well. It may also be a region on a map for which a common areal rate of seismicity is assumed for the purpose of calculating probabilistic ground motions.
Map showing Earth's principal tectonic plates and their boundaries in detail. These plates comprise the bulk of the continents and the Pacific Ocean.For purposes of this list, a major plate is any plate with an area greater than 20 million km 2 (7.7 million sq mi)
The first, six-level intensity scale was proposed by Egen in 1828 for an earthquake in Rhineland. [4] [5] Robert Mallet coined the term "isoseismal" and produced a map for the 1857 Basilicata earthquake with a three-fold intensity scale and used this and other information to identify the epicentral area (a term he also coined).

Thurston's earthquake theorem states that for any two points x, y of a Teichmüller space there is a unique left earthquake from x to y.It was proved by William Thurston in a course in Princeton in 1976–1977, but at the time he did not publish it, and the first published statement and proof was given by Kerckhoff (1983), who used it to solve the Nielsen realization problem.
The USGS estimated that the earthquake could cause economic losses measuring between 1–10% of Vanuatu's GDP. [19] The United Nations Office for the Coordination of Humanitarian Affairs estimated that 116,000 people had been directly affected by the earthquake, [43] equivalent to a third of Vanuatu's population. [44] Among them were 14,000 ...

Seismicity is quantitatively computed. Generally, the region under study is divided in equally sized areas defined by latitude and longitude, and the Earth's interior is divided into various depth intervals on account of Earth's layering: Up to 50 km (31 mi) depth, 50–300 km (31–186 mi), and > 300 km (190 mi).
There are different maps for it based on recent tectonics, seismicity and earthquake focal mechanism. The simplest plate geometry draws the boundary from the Nansen Ridge through a broad zone of deformation in North Asia to the Sea of Okhotsk then south through Sakhalin Island and Hokkaido to the triple junction in the Japan Trench.
