Nations work together to size up Caribbean tsunami hazards
(AGU.ORG, 2018-10-04)El Caribe es conocido por sus playas tropicales y centros de surf, pero no está exento de terremotos y tsunamis. Durante los últimos 500 años, esta región puede haber estado expuesta a aproximadamente 100 tsunamis, de los ... -
New records of historical tsunamis obtained from Costa Rican newspapers
(American Geophysical Union, 2020-12-14)Costa Rica has few records of historical tsunamis, due to traditionally low populated coasts and moderate tsunami potential, among other reasons. As part of the writing of the first tsunami catalog of Costa Rica, the authors ... -
Nuevo enfoque combinatorio para el problema del paseo al azar en un espacio n-Dimensional
(Universidad Nacional (Costa Rica), 1994)Se presenta un nuevo enfoque combinatorio para resolver el problema del cálculo de las probabilidades de paso –probabilidades de transición entre dos posiciones cualesquiera- de una partícula que se desplaza siguiendo una ... -
Numerical modeling of tsunamis originated at Colombia-Ecuador Trench for Costa Rica
(IV Assembly of the Latin American and Caribbean Seismological Commission, LACSC 2022, 2022-10-04)Costa Rica is exposed to tsunamis at both Pacific and Caribbean coasts. Costa Rica has experienced 41 tsunamis since 1746 with moderated impact (Chacón-Barrantes et al., 2021), but the coastal population has increased ... -
Numerical Simulation of Several Tectonic Tsunami Sources at the Caribbean Basin
(2016)According to the NGDC/WDS Global Historical Tsunami Database, the Caribbean Sea has experienced more than 100 historical tsunamis. The most recent tsunami observed in this basin was caused by the 2010 Haity Mw 7.0 earthquake ... -
Numerical Simulations of the 1991 Limón Tsunami, Costa Rica Caribbean Coast
(Pure and Applied Geophysics vol.174 2945-2959 2017, 2017)The second largest recorded tsunami along the Caribbean margin of Central America occurred 25 years ago. On April 22nd, 1991, an earthquake with magnitude Mw 7.6 ruptured along the thrust faults that form the North Panama ... -
