Might the crack turn into a landslide/slump event?

Surely not in our lifetimes, but what if there is evidence the crack is widening? Are the Leilani events are part of the process?
The Kalapana and now Leilani flows are adding more and more weight to the Puna shoreline. Perched above ocean.
Experts here can inform us if this is an abyssal plain, i.e., deep water. A precipitous underwater slope generally means greater possibility of slump.
This map allows a nice close-up. Use magnifier. (The Hilina Slump and Loihi are shown.)

What is reported to have happened to the entire east side of Oahu, resulting in the Koolau Range, suggests the catastrophic nature of these events. Fortunately the time frame is generally in 100,000s of years.
