Ultra low frequency-ULF (1 Hz or lower), kHz and MHz electromagnetic (EM)anomalies were recorded prior to the L'Aquila catastrophic earthquake (EQ) thatoccurred on April 6, 2009. The detected anomalies followed this temporalscheme. (i) The MHZ EM anomalies were detected on March 26, 2009 and April 2,2009. The kHz EM anomalies were emerged on April, 4 2009. The ULF EM anomalywas continuously recorded from March 29, 2009 up to April 2, 2009. "Are EQspredictable?" is a question hotly debated in the science community. Its answerbegs for another question: "Are there credible EQ precursors?". Despite fairlyabundant circumstantial evidence pre-seismic EM signals have not beenadequately accepted as real physical quantities. Therefore, the questioneffortlessly arises as to whether the observed anomalies before the L'Aquila EQwere seismogenic or not. The main goal of this work is to provide some insightinto this issue.
