What's causing the near-daily collapses and 'earthquakes' at Halemaumau?

For over three months, Hawaii Island residents near Kilauea's summit have dealt with ongoing ground shaking, civil defense alerts and light ashfall.

The rumbles often release energy equivalent to a 5.2- to 5.4-magnitude earthquake. Since May, scientists have recorded almost 60 of those magnitude-5 or higher tremblors.

By now, it's known these "earthquakes" don't generate a tsunami threat and the shaking is short-lived.

But according to U.S. Geological Survey scientists, they're not traditional earthquakes (in which plates underground move). And they're no longer caused by steam-driven ash explosions as they were in previous months.

USGS scientist Janet Babb says what triggers the temblors are "collapse events" at Halemaumau.
