This construction is also seen in Scottish polearms, such as the Lochaber axe and Jeddart staff, and bardiches are known to have been imported into Scotland in the 16th and 17th centuries Depending on the design of the particular weapons in question, at times a bardiche may greatly resemble a voulge. While the blade was often very long for an axe (usually exceeding
Types of volcanic eruptions propels it forward. Phreatomagmatic eruptions are another type of volcanic eruption, driven by the compression of gas within magma, the direct opposite of the process powering magmatic activity. The third eruptive type is the phreatic eruption, which is driven by the superheating of steam via contact with magma; these eruptive types often exhibit no magmatic release, instead causing the granulation of existing rock. Within these wide-defining eruptive types are several subtypes. The weakest are Hawaiian and submarine, then Strombolian, followed by Vulcanian and Surtseyan. The stronger eruptive types are Pelean eruptions, followed by Plinian eruptions; the strongest eruptions are called
