The more silaceous the lava, (higher silica content), the more explosive the eruption.

They indicate that an eruption is effusive rather than explosive.

The materials associated with volcanic eruption are Lava flows such pahoehoe lava and Aa lava. Gases that contain mainly water vapor and carbon dioxide. Pyroclastic materials such fire fragments, ash, dust, pumice, lapilli, cinders, harder lava and hot lava as bombs.
When magma reaches the Earth's surface, it is called lava. Lava can flow out of a volcano during an eruption and can cool to form igneous rocks. The characteristics of the lava, such as its temperature and composition, can influence the type of volcanic eruption that occurs.
The most common type of volcanic eruption occurs when magma (the term for lava when it is below the Earth's surface) is released from a volcanic vent. Eruptions can be effusive, where lava flows like a thick, sticky liquid, or explosive, where fragmented lava explodes out of a vent.
