Anomalies of total column CO and O<sub>3</sub> associated with great earthquakes in recent years
Variations of total column CO and O<sub>3</sub> in the atmosphere over the epicenter areas of 35 great earthquakes that occurred throughout the world in recent years were studied based on the hyper-spectrum data from Atmospheric Infrared Sounder (AIRS). It was found that anomalous increa...

| description | Variations of total column CO and O<sub>3</sub> in the atmosphere over the epicenter areas of 35 great earthquakes that occurred throughout the world in recent years were studied based on the hyper-spectrum data from Atmospheric Infrared Sounder (AIRS). It was found that anomalous increases of CO and/or O<sub>3</sub> concentrations occurred over the epicenter areas of 12 earthquakes among the 35 studied ones. However, increases in both CO and O<sub>3</sub> concentrations were found for 6 earthquakes. The O<sub>3</sub> anomalies appeared in the month when the earthquake occurred and lasted for a few months, whereas CO anomalies occurred irregularly. The duration of CO and O<sub>3</sub> anomalies related to the earthquakes ranged from 1 to 6 months. The anomalies of CO concentration related to the earthquake can be mainly attributed to gas emission from the lithosphere and photochemical reaction, while the anomalous increases in O<sub>3</sub> concentration can be mainly due to the transport of O<sub>3</sub>-enriched air and photochemical reaction. However, more work needs to be done in order to understand the mechanism of the CO and O<sub>3</sub> anomalies further. |
