The United States Geological Survey recorded a Magnitude 4.7 Earthquake at a depth of 83.3 km
roughly 15 km to the east of the town of Gonzalo in Monte Plata
Province in the Dominican Republic, slightly before 5.15 am
local time (slightly before 9.15 am GMT) on Sunday 3 June 2018. There
are no reports of any damage or injuries associated with this event, but
people have reported feeling it across much of the Dominican Republic.

The
Dominican Republic forms the eastern part of the island of La
Hispaniola, in the Greater Antilles. The island has a complex
geological structure, with parts of it lying on three different tectonic
plates, and two plate margins running east-to-west across the
island. The northernmost part of the island lies on the North American
Plate. This is divided from the Gonâve Microplate by the Septentrional
Fault Zone, which runs through Rio San Juan, along the north coast of
the Dominican Republic and Haiti, then across the Windward Passage and
along the south coast of Cuba. The Gonâve Microplate is moving east
relative to the North American Plate, pushed by the Mid-Cayman Spreading
centre to the west of Jamaica. To the south the Gonâve Microplate is
separated from the Caribbean Plate by the Enriquilo-Plantain Garden
Fault Zone, which runs across Southern Haiti and the Dominican Republic.
To the west the fault runs through central Jamaica. The Caribbean Plate
is rotating clockwise, effectively moving east relative to the Gonâve
Microplate.
Witness
accounts of Earthquakes can help geologists to understand these events,
and the structures that cause them. The international non-profit
organisation Earthquake Report is interested in hearing from people who may have felt this event; if you felt this quake then you can report it to Earthquake Report here
