Dado que la sequía es frecuentemente asociada a grandes eventos de incendios, investigamos la relación entre grandes incendios y sequías en este período de 160 años. Aquí situamos a éste y otros años en un contexto histórico mediante el examen de registros de incendios en el estado desde 1860. Lengthy droughts, as measured by the Palmer Drought Severity Index (PDSI), were associated with the peaks in large fires in both the 1920s and the early twenty-first century.Įn el año 2020, California experimentó un récord al quebrar el número de grandes incendios. Earlier records show fires of similar size in the nineteenth and early twentieth century. In the last decade, there have been several years with exceptionally large fires. In fact, the 1920’s decade stands out as one with many large fires. Nevertheless, there have been other periods with even greater numbers of large fires, e.g., 1929 had the second greatest number of large fires. This study shows that extreme fire events such as seen in 2020 are not unknown historically, and what stands out as distinctly new is the increased number of large fires (defined here as > 10,000 ha) in the last couple years, most prominently in 2020. Since drought is commonly associated with large fire events, we investigated the relationship of large fire events to droughts over this 160 years period. Here, we place this and other recent years in a historical context by examining records of large fire events in the state back to 1860.
