Latin American and Caribbean Seismological Commission. (

LACSC is the regional association of the International Association of Seismology and Physics of the Earth's Interior (IASPEI), which in addition to LACSC, has the European Seismological Commission (ESC), Asian Seismological Commission (ASC) and the African Seismological Commission (AfSC) .

IASPEI, and therefore LACSC, promote the study of earthquakes and other seismic sources, the propagation of seismic waves and the properties, processes and internal structure of the Earth. See IASPEI, together with other associations such as the Int'l Association of Volcanology and Chemistry of the Earth's Interior (IAVCEI), the International Association for the Physical Sciences of the Oceans (IAPSO), the International Association of Meteorology and Atmospheric Sciences (IAMAS), the International Association of Hydrological Sciences (IAHS), the International Association of Geodesy (IAG) are part of the International Union of Geodesy and Geophysics (IUGG). Currently the LACSC Executive Committee has the following composition:

President: Mario Ruiz (Ecuador)
Vice-President: Marino Protti (Costa Rica)
Past-President: Victor Huérfano (Puerto Rico)
Executive Secretary: Marcelo Assumpção (Brasil)


During the last centuries, several earthquakes of magnitude greater than 7.8 have occurred in the region: Mexico 1985; Ecuador-Colombia 1906 and 1979; Ecuador 1942 and 2016; Peru 1940, 1942, 1966, 1970, 1974 and 2007; and Chile 1906, 1922, 1939, 1943, 1960 and 2010. The 1960 Chile earthquake has the largest magnitude recorded instrumentally, 9.5 Mw. However, earthquakes of even moderate magnitude have caused a very large impact in recent decades: Haiti 2010 (230,000 deaths); Mexico 1985 (10,000); Guatemala 1976 (23,000 deaths); Nicaragua 1972 (10,000); Peru 1970 (66,000), and the list goes on. In addition to this, hundreds of Quaternary fault lines have been mapped in South America, Central America and the Caribbean, posing a high earthquake threat for the coming decades along with associated risks in densely populated areas such as megacities. still growing. We must also consider that seismology is the main method for the study and monitoring of active volcanoes and therefore of their early warning systems.


LACSC Assemblies
The LACSC Assemblies have become the most important seismological congresses in the region. Previous events took place at:

• Bogotá, Colombia, July 23-25, 2014.
• San José, Costa Rica, June 20-22, 2016.
• Miami, USA, May 14-17, 2018, (In conjunction with the Seismological Society of America, SSA). More information in:

The number of attendees at the LACSC Assemblies ranges between 250 and 300 researchers.
