Fifty years ago, the strongest earthquake ever recorded in history rocked the city of Valdivia, Chile . On May 22, 1960, the 9.5 magnitude earthquake  struck the epicenter near the city of Cañete. However, Valdivia was the hardest hit locality with nearly 40% of its building destroyed and leaving close to 20,000 homeless.
Many current users of citizen media are too young to have experienced the 1960 quake, but some like Mauro Barrientos (@maurobarrientos) talked with someone who was there fifty years ago :
Mi awela dijo este terremoto ni se compara al del terremoto de valdivia en 1960
However, the legacy that the earthquake has had on Chile's history was on the minds of many around the country. Yondaime Andres (@EomerElessar) writes :
a toodos se les aparece el fantasma del 60 por eso el temor
From the city of Valdivia, Betsabé Sandoval (@_Nahra) has been uploading various vintage photos at Twitpic  of the destruction from the 1960 earthquake, including this photo  of the damage to the Valdivia Cathedral. In total, she has uploaded 10 different photographs.
There are many Twitter users who currently live in the city of Valdivia. Throughout the day, they have been reacting to the developments of the 2010 earthquake and how their fellow residents were affected. The Twitter user @tapeks writes about the current mood of the city :
Se ve el temor en la gente, todos andan intranquilos y las calles se ven desoladas, se ve tan raro #Valdivia
With the approach of nightfall on the first night after the earthquake, Evelyn Arriagada (@evelynarriaga)  and Daniela Contreras (@dcontrerasl)  both remark how things are a little calmer, but everyone is heading to bed with a little bit of fear.
Nevertheless, not only is the damage caused by the 1960 earthquake on the minds of many, but also the reaction by the Chilean people 50 years ago. Pancho Ballesteros (@Pancho_B) writes :
