Since the latter 20th century , the political situation in Xochistlahuaca has been unstable . It is complicated by the fact that there are two authorities , traditional indigenous councils , mostly Amuzgo and the constitutional municipal government , dominated by mestizos . The Amuzgo council usually consists of elders selected for their participation in the community , especially the sponsorship of religious festivals as well as family ties . The municipal authorities are dominated by mestizos because of their command of Spanish and greater ties to the overall Mexican culture . This has caused tension between the two groups which has been complicated by converts to Protestantism who reject the traditional councils and independent political movements , especially since the 1980s . In the early 2000s , the political situation was particularly volatile with the municipal president Aceadeth Rocha refusing to recognize certain traditional authorities . In 2001 , a group of Amuzgos took over the municipal palace to protest . This action spurred the creation of the Frente Cívico Indígena de Xochistlahuaca and the Frente Comunitario de Xochistlahuca , which have had influence in both political and social issues . Sentiments among the Amuzgos have run particularly against the PRI political party , which dominated municipal politics for decades and mostly in favor now towards National Action Party ( PAN ) . Since 2006 , both traditional and municipal authorities have recognition but the situation remains uneasy . On March 20 , 2012 , a 7.4 earthquake was centered very near the municipality affecting it and most of the rest of the Costa Chica region . It was the strongest in Mexico since the 1985 earthquake . Over fifteen communities in the municipality suffered moderate damage including large cracks and separated walls in a number of community churches and landslides covering roads
