List of extinct volcanoes

List of extinct volcanoes includes volcanoes which scientists consider unlikely to erupt again.^[1] A volcano which has not erupted in the past 10,000 years is often listed as extinct.^[2]

The extinct volcano no longer has a magma supply. An extinct volcano is no longer near an active geologic hot spot, if it ever was.^[3]

Volcanologists sometimes can't tell whether a volcano is extinct or dormant. A caldera that has not produced an eruption in tens of thousands of years is likely to be considered inactive.^[4] Dormant volcanoes may still erupt, whereas extinct ones cannot.

There are many examples of extinct volcanoes.

• Olympus Mons on Mars, the biggest volcano in the Solar System.
• Hawaiian–Emperor seamount chain in the northern Pacific Ocean^[5]
• Huascarán in Peru^[6]
• Kyushu-Palau Ridge in the Philippine Sea^[7]
• Mount Buninyong in Victoria Australia^[8]
• Tamu Massif in the Northwest Pacific Ocean^[9]
• Waw an-Namus in Libya^[10]
• Edinburgh Castle in Scotland is located on a dolerite plug, the remnant of a volcano that went extinct many millions of years ago.
• Doshi hill in Haryana, India is an extinct volcano and has been sleeping since 770 million years
