SALT LAKE CITY — Two aftershocks hit the Wasatch Front Thursday morning. The area has experienced dozens of earthquakes since a 5.7 magnitude shake rocked the area on March 18.

The initial magnitude of the first aftershock, which hit at 10:12 a.m., was measured at 3.3 before being downgraded to 3.2, but was then reverted back to 3.3, according to the U.S. Geological Survey.

The second aftershock followed at 10:21 a.m. and was initially measured at magnitude 3.0, according to the USGS.

The March 18 earthquake, which struck just northeast of Magna, was the largest in Utah since 1992 and caused property damage to many buildings in the Salt Lake Valley. No deaths or significant injuries were reported.

The epicenter for both Thursday aftershocks was located just south of the Salt Lake City International Airport, several miles east of where most of the aftershocks have been recorded since last week.

Despite the dozens of aftershocks over the past week, experts say it is likely that the 5.7 magnitude initial quake will be the strongest in the series. In 95% of cases, the first earthquake in such a series is the strongest, according to the Utah Division of Emergency Management.
