Nevertheless, as the first premier of post-communist Poland, Tadeusz Mazowiecki, put it twenty years later, on June 4, 2009, he wished western leaders would acknowledge the fact that the Berlin Wall would not have fallen if the the Poles had not defeated their communists on June 4 of 1989.
Mayon is a classic stratovolcano with a small central summit crater. The cone is considered the world's most perfectly formed volcano for its symmetry, which was formed through layers of lava flows and pyroclastic surges from past eruptions and erosion. The upper slopes of the basaltic-andesitic stratovolcano are steep, averaging 35â40 degrees.
Mayon volcano, in SE Luzon, is the most active volcano in the Philippines. Its classic, symmetrical profile, which rises above the Albay Gulf to a height of 2462 m, is the result of a structurally simple volcano where eruptions have occurred from a single central conduit. hot lahar sweeps down a channel on the SW flank of Mayon volcano in the Philippines on September 14, 1984, five days after the onset of an eruption. The water temperature of this lahar was about 80 degrees Centigrade.
