Bahía Solano Fault
The Bahía Solano Fault (Spanish: Falla Bahía Solano), Utría Fault or Utría-Bahía Solano Fault is a westward dipping thrust fault in the department of Chocó on the Pacific Coast of Colombia. The fault has a total length of 290.6 kilometres (180.6 mi) and runs along an average north–south strike of 347 ± 13 from the Panama-Colombia border to Bajo Baudó. The fault is partly offshore in the bays of Solano and Utría and crosses the Chocó Basin and the coastal Serranía del Baudó. Movement of the fault produced the Mw 6.5 1970 Bahía Solano earthquake.
