    Abstract
    "Kliuchevskoi and Pavlof Volcanoes in Kamchatka, Russia and Alaska, USA respectively, are two of the most active stratovolcanoes in the North Pacific Region. Effusion rates were calculated and analyzed for the most recent eruptions by balancing the radiative energy with the thermodynamic properties of the lava with data from three near-polar orbiting satellite sensors to establish a trend in the eruptive behavior of these volcanoes. Effusion rates for the 1994, 2005, 2007 eruptions of Kliuchevskoi reached 8.0 m³ s⁻¹ with cumulative lava volumes as high as 0.033 km³. Effusion rates for the 1996 and 2007 Pavlof eruptions were as high as 7.3 m³ s⁻¹ with cumulative volumes as high as 0.036 km³. Effusion rates and cumulative lava volumes for Kliuchevskoi increased with each eruption, where as the Pavlof volumes and rates decreased. Eruptions with the longest thermal precursors produced the largest volumes of lava"--Leaf iii
