Cephalonia bushes and resulting in the loss of some properties. The forest fire scar was visible for some years. In mid-November 2003, an earthquake measuring 5.3 on the Richter magnitude scale caused minor damage to business, residential property, and other buildings in and near Argostoli. Damages were in the €1,000,000 range. On the morning of Tuesday, September 20, 2005, an early-morning earthquake shook the south-western part of the island, especially near Lixouri and nearby villages. The earthquake measured 4.9 on the Richter magnitude scale, and its epicentre was located off the island at sea. Service vehicles took care of the area,
Moment magnitude scale band. To simplify this calculation, he noted that the lowest frequency parts of the spectrum can often be used to estimate the rest of the spectrum. The lowest frequency asymptote of a seismic spectrum is characterized by the seismic moment, . Using an approximate relation between radiated energy and seismic moment (which assumes stress drop is complete and ignores fracture energy), (where E is in Joules and is in Nformula_4m), Kanamori approximated by The formula above made it much easier to estimate the energy-based magnitude , but it changed the fundamental nature of the scale into a moment magnitude scale.
