It looks like the Taconic arc has its continuation along the western continental margin of Siberia and both of them constitute a single Taconic-Enisej (also spelled Yenisei or Yenisey) volcanic arc.

The El Salvador Fault Zone (ESFZ) is one of these features, extending along the El Salvador volcanic arc (Fig 1) for about 150 km long as a right-lateral strike-slip fault system, as wide as 20 km (Martinez-Diaz et al., 2004).
