A thunderous daytime display based on the most powerful fireworks currently available: the "masclets". The mascletà itself is like a concert of gunpowder: pyrotechnicians carefully study the rhythm of firework sequences, launches and whistles, combining them in a spectacular crescendo that concludes with the "terremoto" (earthquake): hundreds of “masclets” exploding on the ground simultaneously. All of this happens in barely six or seven minutes. There is no fireworks display comparable to a “mascletà” and the emotions it arouses can only be understood by experiencing it at least once. The City Council of Valencia organizes a calendar of "mascletaes" from the 1st of March to St. Joseph’s Day (19th March), at the Plaza del Ayuntamiento, the city's urban centre. At 2 o' clock in the afternoon, thousands and thousands of people congregate there, every day, to witness a unique event that should not be missed by anyone who plans to experience the genuine Fallas atmosphere.
