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,
Magnitude (astronomy) by astronomers are: The difference between these concepts can be seen by comparing two stars. Betelgeuse (apparent magnitude 0.5, absolute magnitude −5.8) appears slightly dimmer in the sky than Alpha Centauri (apparent magnitude 0.0, absolute magnitude 4.4) even though it emits thousands of times more light, because Betelgeuse is much farther away. Under the modern logarithmic magnitude scale, two objects, one of which is used as a reference or baseline, whose intensities (brightnesses) measured from Earth in units of power per unit area (such as watts per square metre, W m) are and , will have magnitudes and related by
