The Zona Volcànica de la Garrotxa Natural Park (Catalan: ') is a natural park area covering a Holocene volcanic field (also known as the Olot volcanic field) in Catalonia, northeastern Spain. The volcanos, of which there are about forty within the park, are no longer active, with the last eruption (Croscat) occurring about 11,000 years ago. However, the region is still seismically active, and a large earthquake in 1428 caused damage to buildings and twenty deaths in Barcelona, to the south. More recent earthquakes in 1901 and 1902 caused shaking but little damage.
