|Region:||Japan, Taiwan, Marianas|
|Measurement method(s):||InSAR, GPS - continuous, GPS - campaign, Levelling, Strainmeter, Tiltmeter|
|Duration of observation:||1892 - present (levelling), 1996 - present (GPS), 2006 - 2012 (InSAR), 1987 - present (tilt), 1990 - present (strain)|
|Inferred cause of deformation:||Magmatic|
|Characteristics of deformation:||
Aira caldera is located within Kagoshima Bay at the southern end of Kyushu in Japan. Sakurajima, an active andesitic stratovolcano, sits on the southern rim of the caldera. It is Japan’s most active volcano, often experiencing daily Vulcanian eruptions.
