Mount Pinatubo 1991, El Chichn 1982) can inject sulfur-containing compounds into the upper atmosphere. What we really offer is information that fills critical gaps in technology and in science knowledge. Corrections? 2 What was the effect of the eruption of Mount Pinatubo in 1991? We couldn't take the risk if we couldn't tell the difference between ash, water and ice clouds. Obviously, communication is faster. Naval Base Subic Bayduring "Operation Fiery Vigil." , at the time of the Mount Pinatubo eruption the moderate CP El Nio of 1991 also transitioned to EP in 1992, similar to what we find in our CPE simulations. What is the difference between a PSC motor and an ECM motor? Before 1991, the mountain was inconspicuous and heavily eroded.It was covered in dense forest which supported a population of several thousand . I feel like its a lifeline. A: I really think that the remote sensing capabilities we have from space are the big game-changer these days. Volcanic eruptions in . 3.1.3 EPE Ensemble.
