Breaching - John Seach
|Breaching is a term to describe a
lava flow breakout. The conditions from breaching require a high channel
pressure and more fluid lava in the channel compared to the edges. Aa lava
is the most prone to breaching.
Breaching usually occurs in the upper
half of the lava flow. Therefore breaching tends to widen the lava flows
rather than extend them lengthways. Note: It is rare for breached lava
flows to extend more than 50% more than the original flow length.
Note: lava flows cool quicker on
steep slopes and therefore stops quicker.
