Only plinian and pelean volcanic eruptions features what flow?
Plinian and Pelean eruptions poth commonly produce pyroclastic flows. However, such flows can also occur with Vulcanian eruptions.
Does a pyroclastic flow occur during during small earthquakes?
No. Pyroclastic flows are a result of volcanic eruptions.
When did Krakatoa erupt in 1884?
Karkatoa did not erupt in 1884. Small eruptions began on June 16 and culminated in a series of massive explosions on August 27.
What are some examples of a fissure eruption?
Fissure eruptions occur when magma flows up through cracks in the ground and leaks out onto the surface. These often occur where plate movement has caused large fractures in the earth's crust, and may also spring up around the base of a volcano with a central vent. Fissure eruptions are characterized by a curtain of fire, a curtain of lava spewing out to a small height above the ground. Fissure eruptions can produce very heavy flows, though the lava is generally slow moving. They are usually at the base of a volcano or at the mid ocean ridge, but often at other volcanoes, such as the Hawaiian volcanoes, as well. (credit to yahoo answers too.)
Why did the volcano outside of Pompeii erupt?
Mount Vesuvius erupted in 79 A.D. because this is what active volcanoes do. They continually smoulder and produce eruptions every few thousand years. Scientific research has shown that Mt Vesuvius was formed 25,000 years ago and was built up by a series of small lava flows and by some eruptions. Around 19,000 years ago, there was the beginning of large explosive eruptions (eruptions which involve explosions which throw volcanic ash in the air). A large explosive eruption which occurred 18,000 years ago created the mountain's current caldera (the cauldron-like feature at the top). This was followed by a series of non-explosive, but lava-producing eruptions. There was a large explosive eruption 11,000 years ago and three small explosive eruption 8,000 and 5,000 years ago and 3,800 years ago there was a large one. The explosion which buried Pompeii and Herculaneum in 79 A.D. was the last large explosive eruption of Mt Vesuvius. There will be further explosive eruptions in the distant future.

When did Mt Saint Helen erupt most recently?
Since late 1986 several periods of increased seismicity have occurred. Between 1989 and 1991 there were about 30 bursts of brief but intense seismic activity lasting minutes to hours. Several of these bursts were accompanied by small explosions from the dome. The explosions formed a new vent on the north side of the dome and produced small eruption columns that rose a few miles above the volcano. A few explosions also hurled hot rocks three feet in diameter at least 1/2 mile northward from the dome, generated small pyroclastic flows in the crater, and formed small lahars. During 1995 and 1998 seismicity increased for several months, but there were no accompanying explosions.
What kind of eruption is produced when basaltic lava that is low in silica flows from a volcano?

Are volcanic eruptions preceded by small earthquakes?
