The earth continued to shake Wednesday in Mexico, with 48 medium-intensity aftershocks following a 7.8-magnitude quake the day before. "So far, there have been 48 aftershocks above 3.8 (magnitude)," dpa quoted Mexico's National Seismological Service as saying early Wednesday. Tuesday's quake - the epicentre was in the southern Mexican state of Guerrero, near the Oaxaca state boundary - caused no deaths, but injured 11 people and damaged hundreds of buildings.
