“…Variations both in nitric oxide (Matsuda and Ikeya, 2001) and atmospheric Rn concentration (Yasuka et al, 2006) prior to the January 1995 Kobe earthquake indicated gases emitted from the crust in the epicentral area. In addition, higher values of CO concentrations deduced from MOPITT satellite at the levels of 1000 and 850 hPa one week prior to the 26 January 2001 Gujarat M s = 7.6 earthquake were found (Singh et al, 2010a). In the studied cases, obvious anomalies of CO concentration along the San Andreas Fault in March and April associated with the 5 April 2010 Baja California M s = 7.1 earthquake (Fig.…”

“…The ozone concentration was low on the day of the earthquake occurrence, increased gradually after the event and reached a maximum value and thereafter decreased to its normal value (Ganguly, 2009;Singh et al, 2007). In addition, increases of CO concentration deduced from Measurements of Pollution in the Troposphere (MOPITT) occurred prior to the 26 January 2001 Gujarat M s = 7.6 earthquake (Singh et al, 2010a), the 15 January 2001 Taiwan M s = 7.5 earthquake (Guo et al, 2006), the 6 June 2000 Jingtai M s = 5.9 earthquake in Gansu Province, northwestern China (Yao et al, 2005) and the M s = 6.9 earthquake of 8 June 2000 in northern Myanmar (Yao et al, 2005). An anomalous variation of the total column water vapor after the Gujarat earthquake was also retrieved using SSM/I microwave radiometer on Tropical Rainfall Measuring Mission (TRMM) satellite (Dey et al, 2004).…”

Abstract. Variations of total column CO and O 3 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 3 concentrations occurred over the epicenter areas of 12 earthquakes among the 35 studied ones. However, increases in both CO and O 3 concentrations were found for 6 earthquakes. The O 3 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 3 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 3 concentration can be mainly due to the transport of O 3 -enriched air and photochemical reaction. However, more work needs to be done in order to understand the mechanism of the CO and O 3 anomalies further.

“…Recently, anomalous changes to the ground, atmosphere and ionosphere, observed by both Earth-and space-based instrumentation, were found to be associated with several earthquakes that occurred in China, Taiwan, Europe and Japan (Walia et al 2006, Yasuoka et al 2006, Cioni et al 2007, Omori et al 2007, Sharma et al 2008, Anagnostopoulos et al 2010b, Hayakawa and Hobara 2010, Singh et al 2010a. These recent reported pronounced changes in the various surface and atmospheric parameters a few days prior to various earthquakes provide a strong evidence of lithosphere-atmosphere-ionosphere coupling.…”

The total electron content (TEC) derived from the global positioning system (GPS) at Varanasi (latitude 25.38 N, longitude 82.998 E), India has been measured during 2007 and 2010. We have chosen nine earthquakes (M 4 5) that occurred within 2000 km of Varanasi during 2007 and 2010 to study the changes in TEC associated with these earthquakes. A monthly median (MM) of the TEC and associated inter quartile range (IQR), upper bound (UB) and lower bound (LB) are utilized as a reference for identifying abnormal signals during all nine earthquakes. The results show anomalous reductions and enhancements in the TEC. These pre-earthquake ionospheric anomalies appear within 5 days prior to earthquakes. A possible mechanism responsible for ionospheric anomalies associated with earthquakes is discussed.

“…An enhancement in nitric oxide mixing ratio of ten times larger than the average peak level of normal days were reported by Matsuda and Ikeya (2001) before the Kobe earthquake on 17 January 1995. Singh et al (2010a) reported anomalous changes in CO concentrations prior to the main earthquake in Gujarat on 26 January 2001.…”

Variations in ambient atmospheric carbon monoxide (CO) observed at an inland mining site in the IndoGangetic plains, Jaduguda (22� 38′ N, 86� 21′ E, 122 m MSL, ~75 km away from the coast of the Bay of Bengal) during the Tsunami of 26 December 2004 were monitored. CO mixing ratio over this site was measured using a non-dispersive infrared analyzer (Monitor Europe Model 9830 B). Back trajectory analysis data obtained using NOAA Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) Model was also used for this study. Variations in CO mixing ratio at a coastal site, Thiruvananthapuram (8� 29′ N, 76� 57′ E, located ~2 km from the Arabian Sea coast) have also been investigated using CO data retrieved from the Measurement Of Pollution In The Troposphere (MOPITT) instrument. Ground-based measurements indicated abnormal variations in CO mixing ratio at Jaduguda from 25 December 2004 evening (previous day of the Tsunami). MOPITT CO data showed an enhancement in CO mixing ratio over Thiruvananthapuram on the Tsunami day. Back trajectory analyses over Thiruvananthapuram and Jaduguda for a period of 10 days from 21 st to 30 th December 2004 depicted that there were unusual vertical movements of air from high altitudes from 25 December 2004 evening. CO as well as the back trajectory analyses data showed that the variations in the wind regimes and consequently wind driven transport are the most probable reasons for the enhancement in CO observed at Jaduguda and Thiruvananthapuram during the Tsunami.
