Notes

Latitude, longitude and altitude are given for the highest point on the volcano except for those volcanoes with calderas. If there is an active eruptive center within the caldera, the latitude, longitude, altitude listed are for this location. When the altitude of the eruptive center is lower than the caldera rim, the maximum altitude on the rim is the second value listed. When there is no active eruptive center, the position is for the center of the caldera and altitude for highest point on rim.

Letters used after the main type designation have the following meanings: A - indicates activity within a summit caldera or large crater. C - indicates that this new volcano formed on the rim or flank of an older caldera. P - indicates that smaller cones or vents occur on the flanks of calderas, stratovolcanoes or shield volcanoes. S - indicates that larger satellite volcanoes occur on the flanks of calderas, stratovolcanoes or shield volcanoes. # - when combined with S or P gives the number of satellite volcanoes, cones, or vents. Sometimes this value is a minimum.

"# erptns" is the number of eruptions on record since 1760.

Rock codes are B-basalt, BA-basaltic andesite, A-andesite, D-dacite, RD-rhyodacite, and R-rhyolite. Mineralogical modifiers are hb-hornblende, and px-pyroxene.

Geothermal Potential indicates estimated potential for presence of a developable hydrothermal system. Codes have the following meanings. C - Confirmed, a hydrothermal system with temperatures suitable for power generation has been confirmed by direct observation by drilling. G - Good, abundant thermal springs and/or fumarolic activity. F - Fair, some thermal springs and/or fumarolic activity or Holocene activity with geologic evidence of a shallow magmatic system. P - Poor, no visible geothermal manifestations, no Holocene activity, no geologic evidence of a shallow magmatic system.
