Earthquake reported off South Padre Island shore
SOUTH PADRE ISLAND —
According to the United States Geological Survey, a small earthquake was reported off the Texas Gulf Coast Saturday afternoon.
The magnitude 3.0 earthquake reportedly happened about 10 miles below the surface, so it likely did not cause much damage at the surface, according to Chief Meteorologist Alex Garcia.
It is unknown what exactly caused the quake, but Garcia said the area is dominated by salt domes beneath the gulf waters. The continued supply of sediment poured into the gulf, such as from rivers, puts pressure (weight) on the salt regions. The added weight causes the salt to compact, deform and creates earthquakes. This is called salt tectonics.
It is unknown if any ships or other water vessels were affected by the quake.
