The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Cotopaxi is one of South America's most famous volcanoes and one of its most active ones. With its 5911 m it also ranks among the world's highest active volcanoes (26th highest).
The majestic, snow covered symmetrical stratovolcano is located on the Eastern Cordillera of the Ecuadorian Andes, 60 km south of Quito and 35 km northeast of Latacunga.
Cotopaxi's steep cone has nested summit craters, the outer of which measures 550 x 800 m in diameter.
Cotopaxi erupted more than 50 times since 1738. The most violent historical eruptions of Cotopaxi volcano were in 1744, 1768, 1877, and 1904. its eruptions often produced pyroclastic flows and destructive mud flows (lahars). Some lahars have travelled more than 100 km and reached the Pacific to the west and the Amazon Basin to the east.
At the moment, it has been dormant for over 70 years, which is an unusual long interval in its recent history.
During an overflight of Cotopaxi on 10 May, scientists observed minor gas emissions rising 600 m above the crater and drifting N and NW. Glaciers remained cracked, though glacial melting observed in recent months had decreased considerably. The temperature of flank fumaroles had decreased slightly.
Surface activity of the volcano has been mostly low during the past weeks, characterized by degassing / steaming and occasional very weak ash emissions. ...more
According to IGEPN, the level of most monitored geophysical parameters (SO2, volcanic earthquakes, volcanic tremor, deformation) have returned to their pre-eruption background levels. base. However, the overall seismic activity of the volcano is still elevated and some few deep-seated explosive events are being recorded (on average 1-3 / day). [less]
On 29 January IG reported that in recent weeks superficial activity at Cotopaxi was characterized by minor steam emissions from the crater and sporadic gas emissions with minor amounts of ash. ...more
Sulfur dioxide emissions were less than 1,000 tons per day (pre-eruptive levels) and seismicity had almost returned to baseline levels. At 1843 on 24 January a plume with low-to-moderate levels of ash rose 700 m above the crater and drifted W. The emission coincided with a hybrid earthquake.

Latest quakes in Greece: Greece has a lot of earthquake activity, but most of them occur around the margin of the Aegean microplate. The Cycladic islands are located in its center and therefore seismically comparably quiet.
