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,
Absolute magnitude and a difference of n magnitudes in absolute magnitude corresponds to a luminosity ratio of 100. For example, a star of absolute magnitude M=3 would be 100 times more luminous than a star of absolute magnitude M=8 as measured in the V filter band. The Sun has absolute magnitude M=+4.83. Highly luminous objects can have negative absolute magnitudes: for example, the Milky Way galaxy has an absolute B magnitude of about −20.8. An object's absolute bolometric magnitude represents its total luminosity over all wavelengths, rather than in a single filter band, as expressed on a logarithmic magnitude scale. To convert
