Earthquakes near San Francisco de Macorís through history

It was also the deadliest: NOAA records 1,790 deaths for it. NOAA’s list of significant earthquakes has 11 here, back to 1564. NOAA records deaths in 3 of the events here, 1,868 in all. The latest on NOAA’s list is a magnitude 4.5 on October 16, 2003 (Moca, Santiago). NOAA’s record here begins on April 20, 1564 with an earthquake (Concepcion De La Vega). It grows thinner going back: 5 of the 11 significant earthquakes NOAA lists here are from 1927 on. NOAA lists 2 tsunamis that began within 100 km of San Francisco de Macorís, and 3 from elsewhere that reached it with deaths or a metre of water or more. The highest water NOAA records here was 5 m, on August 4, 1946. The deadliest here came on August 4, 1946 from a magnitude 7.9 earthquake (Northeastern Coast): NOAA’s runup records count 1,790 deaths within 100 km of San Francisco de Macorís.

• An event counts for San Francisco de Macorís when it began within 100 km of its centre, or 200 km for an earthquake of magnitude 7 or more. Damage can reach further.
• USGS counts here start at magnitude 6: the catalogue’s smaller quakes thin out going back, where few instruments listened.
• NOAA lists significant events only: earthquakes that killed, did about $1 million of damage, reached magnitude 7.5 or intensity X, or raised a tsunami, and eruptions and tsunamis by like measures. Magnitudes before 1900 are its estimates from written accounts.
• Deaths are NOAA’s total for each event, wherever people died, its tsunami and fires included. A tsunami counts the dead its runup records give for this place: NOAA’s total for a tsunami includes its source quake’s.
• A tsunami from elsewhere counts where one of its runups killed or rose a metre or more.
• Counted to October 19, 2026, as is the map. The last 30 days ask USGS again.
