The tectonic structure of Iceland is characterized by various seismically and volcanically active centers. Mexico lies within two seismically active earthquake zones. The uneven distribution of earthquakes naturally biases models to better resolution in seismically active regions. Opponents say that hydraulic fracturing poses risks in the seismically active region. The lateral displacements can be caused by wind or seismically induced inertial forces. The Pombaline buildings were among the earliest seismically protected constructions in Europe. The Pombaline buildings are among the earliest seismically protected constructions in Europe. This rift is not seismically active. Pune is north of the seismically active zone around Koyna Dam. Moreover, the dam is situated in a seismically active zone. There are also eight nuclear power plants located along the seismically active West coast. Morgan Hill is located within the seismically active San Francisco Bay region. Because of many fault lines in the vicinity, Junagadh is in a seismically active zone. Adelaide and its surrounding area is one of the most seismically active regions in Australia. This area is still quite active seismically.
