This database contains the supervised classification of the tweets originally posted in English related to the 10th anniversary of the Maule Earthquake in Chile on Febrary 27, 2010. Tweets were collected by a third-party vendor between December 11, 2019 to April 23, 2020 including the hashtags: #27F, #Maule, #PorUnaLeyDeCostasEnChile, #Chile and #Terremoto. A total of 44,189 tweets were collected, from this sample, only 237 (0.54%) tweets were originally posted or retweeted in English, which can be explained by the fact that Chile is a Spanish speaking country. After removing the not related tweets the sample was reduced to 121 (0.27%). Despite being a small sample, based on additional analysis, we state that this is a representative sample of the opinions related to this commemoration. The high number of not related tweets is given that the hashtag #27F is also included in tweets related to celebrating the Independence of the Dominican Republic and the International Polar Bear Day; the birthday of José Vasconcelos (Mexican writer, philosopher, and politician), Elizabeth Taylor (American actress) and José Antonio Meade Kuribreña (Mexican politician). Other tweets that include the hashtag #27F are those commemorating the 'Caracazo' (protests, riots and looting that started on February 27 1989 in Caracas, Venezuela); the dead of Mauricio Garcés (Mexican actor) and Eyker Daniel Rojas (Venezuelan citizen assassinated during the Caracazo).
