| Mount Saint Helens in Washington and Mount Pinatubo in the Philippines are examples of stratovolcanoes. |
|
| The June 1991 Mount Pinatubo eruption produced voluminous pyroclastic flows and a major Plinian umbrella cloud during its paroxysmal phase. |
|
| On June 15, Mount Pinatubo spewed ash 40 km into the air and produced huge ash flows and mudflows that devastated a large area around the volcano. |
|
| Before its catastrophic eruption of 1991, Pinatubo was an inconspicuous volcano, unknown to most people in the surrounding areas. |
|
| There are many active volcanoes such as the Mayon Volcano, Mount Pinatubo, and Taal Volcano. |
