Statements by the Puerto Rico Seismic Network on swarm
Seismic Fault Zone from 19 ° N
The Puerto Rico Seismic Network (PRSN) has recorded a total of 151 tremors on
16, 17 and 18 March. From March 16th at 22:23 GMT (17:52 local time) until 18
March at 08: 43 GMT (04:43 local time), have located a total of 55 tremors
Fault zone 19 ° N over a period of 35 hours. Approximately 96 of the 151 earthquakes
have been classified as undetermined due to lack of information to process
(registered in less than 3 seismic stations). This swarm is generated in the Area
Failure of the 19 ° N, specifically to 69 km north of Manatee (between latitudes 19.2 ° N-
18.8 ° N and longitudes 66.7 ° W - 66.3 ° W). Of the total of earthquakes located, none have been
reported as felt in Puerto Rico and the Virgin Islands. The magnitudes of the swarm
ranged from 2.2 to 3.0 Md Md and depths of 4.1 km to 44.4 km. Of total
earthquakes, 4 have had magnitudes greater than 3.0 Md and 6 of these earthquakes could not
calculate magnitude. A swarm is when there is a sequence of earthquakes with
same characteristics, in the same region, within a few hours or days.
The PRSN continues processing routinely seismicity for the region of Puerto
Rico and Virgin Islands. For the month of March, to this day, the PRSN has located
approximately 138 earthquakes in the region of Puerto Rico. This seismicity is considered
normal for our region. For more information on the seismicity in the region of Puerto
Rico visit our website
