Although the total death toll is unknown, it may be as high as 1,600. Earthquake The earthquake was associated with strike-slip faulting at a shallow depth; a common characteristic for earthquakes of this depth in the region of northern Venezuela.Diane I.

The earthquake in 1929 is thought to have ruptured approximately 30–40 km of the fault.F.A. Audemard M.N. Machette J.W. Cox R.L. Dart K.M.

Seismological interpretation of the historical data related to the 1929 Cumana earthquake, Venezuela Andean Geodynamics: Extended Abstracts 1996 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/divers4/010008559.pdf 0767-2896 Most of the surface rupture was offshore, and only 4 km of it was visible at the surface, extending east–west. The surface-wave magnitude (s) was calculated to be 6.3; a revision of 6.9 which was considered an overestimation. The same fault segment is thought to have partially ruptured during the 1997 Cariaco earthquake, which occurred east of the 1929 event. It is believed that the 1929 earthquake ruptured a segment that was involved in a 1797 event. Tsunami At the coast of Cumaná, in Puerto De Sucre, survivors witnessed the a drawback of the sea by as much as 200 meters. The tsunami reportedly swept away some homes located along the shore, killing some 40 individuals. The maximum tsunami height was measured at 3 m.Mirna Guevara Simulación Numérica Del Tsunami Asociado Al Terremeto Del 17 De Enero De 1929 En La Ciudad De Cumaná, Una Contribución A Los Estudios De Riesgo En Las Costas Venezolanas 2014 http://saber.ucv.ve/bitstream/123456789/16698/1/TEG%20Mirna%20Guevara.pdf Numerical Simulation of the Tsunami Associated With Thee arthquake of January 17, 1929 in the City Ofcumaná, A Contribution To Risk Studies in the Venezuelan Coasts Spanish September 1, 2021 September 1, 2021 https://web.archive.org/web/20210901125644/http://saber.ucv.ve/bitstream/123456789/16698/1/TEG%20Mirna%20Guevara.pdf dead Cumaná suffered severe damage from the tsunami, and the waves were recorded in four other cities. Two launches, each weighing 5-tons were carried and dumped inland. Boats were destroyed.James F. Lander Lowell S. Whiteside Patricia A.

The shaking which lasted 30 seconds, severely damaged a theater, which has now been converted to a cathedral. The Church of Santa Inés suffered partial destruction of its structure, as well as to the San Antonio de la Eminencia castle. A clock tower on the Church of Santa Inés stopped working at the time the earthquake struck. After the earthquake, new towers were built around the church during restoration works. Ground collapse and landslides were reported. The earthquake was also felt in Barcelona, Margarita, Güiria, Carúpano, Río Caribe, Caracas, and Irapa.Zoraida Pereira La Investigación Sismológica en Venezuela 2002 Impresos Lauper Caracas, Venezuela 980-6069-11-0 Spanish No official figure for the death toll exists, although it has been estimated to be as much as eight percent of the population of 20,000.TERREMOTO DE CUMANÁ https://turismosucre.com.ve/cumana/terremoto1929/ Sucre Turística 1 September 2021 At least 800 people were injured.
