That shaking Friday night was not the result of the wine. A 5.9 magnitude earthquake at 7:54 p.m. was followed at 9:30 by a magnitude 5 quake some 15 kilometers (about 9 miles) south of Laurel in the southern zone. The first quake was reported that night by A.M. Costa Rica.
The second quake does not appear to have been felt strongly in the Central Valley, although there were reports of it all over the country.
The 7:54 p.m. quake was centered near Zarcero but still attributed to the Coco tectonic plate.
