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 corresponds to absolute bolometric magnitude 4.74. Placing a radiation source (e.g. star) at the standard distance of 10 parsecs, it follows that the zero point of the apparent bolometric magnitude scale corresponds to irradiance . Using the IAU 2015 scale, the nominal total solar irradiance ("solar constant") measured at 1 astronomical unit () corresponds to an apparent bolometric magnitude of the Sun of −26.832. Following Resolution B2, the relation between a star's absolute bolometric magnitude and its luminosity is no longer directly tied to the Sun's (variable) luminosity: where The new IAU absolute magnitude scale permanently disconnects the scale from
