A major earthquake struck western Haiti on Saturday morning and was felt across the Caribbean.

Authorities report that 29 people have been confirmed dead and the prime minister has declared a state of emergency.

People fled their homes for fear that buildings might collapse when the magnitude 7.2 tremor struck at approximately 8.30am.

A 5.2 magnitude aftershock was also recorded about 20 minutes after the initial shaking, several smaller shocks followed.

The epicentre of the quake was 8km (5 miles) from the town of Petit Trou de Nippes, about 150km west of the capital Port-au-Prince.

Learning from the 2010 earthquake
Dr Susan Hough at the USGS notes that there is now a network in place in Haiti to help understand earthquakes that strike the country as part of the legacy of the 2010 quake.

Dr Hough notes that much of the shaking appears to have occurred in sparsely populated parts of the country.

Unicef on standby to help in Haiti
Unicef Latin America tweeted: “We’re concern and deeply saddened by the news of today’s strong 7.2 magnitude earthquake in Haiti. @UNICEFHaiti is on standby to provide support to communities and the Government. We stand in solidarity during this difficult time.”

From Reuters:

The earthquake comes as Haiti is already mired in intertwined political, humanitarian, and security crises.

The government is in turmoil, a month after the assassination of President Jovenel Moise, while swaths of the country are facing growing hunger, and healthcare services are overwhelmed by Covid-19. Access to the southern region, where the quake struck, has been restricted by gang control of key areas.

“This country just never finds a break! Each year of mismanagement did not hurt but the cumulative effects made us vulnerable to everything,” said Haitian entrepreneur Marc Alain Boucicault on Twitter.

“Its going to take years to fix things and we have not even started!”

Major Earthquake Strikes Haiti, 1-3 Meter Tsunami Waves Possible Near Haitian Coast

 SATURDAY, 14 AUGUST 2021, 8:50

At 8:29 AM Saturday 14th August 2021, a major (preliminary) magnitude 7.2 earthquake struck the Haitian Peninsula approximately 12.2 KM NE of Saint-Louis du Sud, Sud, Haiti, 33.2 KM ENE of Les Cayes, Sud, Haiti, and 42.6 KM WSW of Miragoâne, Nippes, Haiti.

Though earthquake parameters are expected to change in the coming hours as more data comes to hand, this major earthquake struck at a depth of 10 kilometers, centered on land at 18.352°N 73.480°W.

According to the United States Geological Survey (USGS) and the European-Mediterranean Seismological Centre (EMSC), light to moderate shaking was reported across Jamaica, Cuba, Southeastern Bahamas, the Tucks, and Caicos and the Dominican Republic. Strong to severe shaking has been reported in Haiti, with violent shaking reported near the epicenter of the quake.

The Pacific Tsunami Warning Center, responsible for issuing tsunami threat messages for the Caribbean Region, stated in a Tsunami Information Statement at 8:38 AM, “Based on all available data, there is no significant tsunami threat from this earthquake. However, there is a very small possibility of tsunami waves along coasts located nearest the epicenter.”

However, in their second update, the Pacific Tsunami Warning Center is now warning that tsunami waves between 1.0 meters and 3.0 meters are possible. The PTWC advises “Actual amplitudes at the coast may vary from forecast amplitudes due to uncertainties in the forecast and local features. Maximum tsunami amplitudes on atolls or small islands and at locations with fringing or barrier reefs will likely be much smaller than the forecast indicates.”

Pacific Tsunami Warning Center Threat Message #2

Aftershocks have been reported felt in Haiti, with the largest so far occurring at 8:49 AM at a preliminary magnitude of 5.2.

According to the USGS, there high numbers of casualties are probable with significant damage likely.

Note that different seismic monitoring agencies use different methods, or several methods, for processing quake parameters across the globe. Each method has its limitations and will likely produce different results within the ranges of the data’s uncertainty. This is generally accepted within the scientific community.

Earthquake Magnitude & Intensity

Earthquakes *cannot* be predicted – meaning the precise time, date, magnitude, depth, etc. cannot be known ahead of time based on current research and technology.

Earthquake Prediction & Forecasting

Seismic waves from the 8:29 AM Haitian earthquake are rolling across Trinidad and Tobago. These waves are too small to be felt, normal for large earthquakes and generally are only detected by very sensitive instruments (seismometers). pic.twitter.com/ldoIlegbhh— Kalain Hosein (@KalainH) August 14, 2021

Historical patterns indicate great quakes (M8.0+) on the Richter Scale have occurred every century or so in the region. The probability of another event at that level is high since the last >M8.0 earthquake occurred in 1843.
