Zusammenfassung |
Variations of total column CO and O3 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 O3 concentrations occurred over the epicenter areas of 12
earthquakes among the 35 studied ones. However, increases in both CO and
O3 concentrations were found for 6 earthquakes. The O3 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
O3 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 O3 concentration can be mainly due to
the transport of O3-enriched air and photochemical reaction. However,
more work needs to be done in order to understand the mechanism of
the CO and O3 anomalies further. |
