SAN SALVADOR: A strong 6.5 magnitude earthquake struck parts of southern Guatemala and El Salvador on Friday, US seismologists said, with only minor damage and no casualties immediately reported. Guatemalan broadcast stations in the western part of the country lost power, according to reports. Landslides clogged up roads and there was slight damage to some homes. Southeastern Mexico was also jolted by at least three aftershocks, including one with a magnitude of 6.1 felt near Ciudad Hidalgo close to the Guatemalan border. In the southern Mexican state of Chiapas, residents evacuated their homes in several towns while power was lost temporarily in Ciudad Hidalgo, a town bordering Guatemala. The US Geological Survey (USGS) said the powerful 6.5 quake struck just six kilometers (3.7 miles) from Pajapita, Guatemala at a depth of 67.7 kilometers.
