A collapse event occurred at Kīlauea’s summit at 4.33pm HST on July 19, according to the USGS.
The energy released by this was equivalent to a M5.2 earthquake.
Rockfalls also occurred from near-vertical cliffs around the Caldera and the Halemaumau crater pit located with the much larger summit caldera of Kilauea.
This came after another explosion at 1.28am local time on July 18, in a blast equivalent to a 5.3 magnitude earthquake.
The Hawaiian Volcano Observatory reported that Fissure 8 continues to be very active and is feeding a lava channel with a broad ocean entry along the Kapoho shoreline.

Fresh lava is also oozing at Kapoho Beach and gas emissions from the fissure eruption and laze at the ocean entry continue to be very high.
When lava meets the ocean, it creates “laze”.
This is a corrosive seawater plume filled with hydrochloric acid and fine volcanic particles that drifts downwind and can irritate the skin, eyes, and lungs.
Close to the ocean entry, flying debris from explosive interaction between lava and water is also a hazard for locals and tourists.
Since the latest explosion on Thursday, Fissure 8 is continuing to erupt lava into the perched channel leading northeastward from the vent.
The southern margin of the flow is about 0.3 miles from the boat ramp at Isaac Hale Park this morning.
The Kilauea volcano has now been erupting since May 3 and has destroyed more than 700 homes.
Lava flowing into the ocean has now created an island 20 to 30 feet in diameter that appeared on July 12, according to USGS.
At least 23 people were injured after a lava bomb which shot from the Kilauea volcano hit a boat of tourists on Monday.
A woman in her 20s was taken to Honolulu with a broken thigh bone.
The other 22 injured people were treated for minor burns and scrapes, including the 12 who were treated at a hospital in Hilo.
However, Hawaii tour boat operators plan to keep taking visitors to see lava spewing from the volcano.
The only other serious injury over the past two months was to a man who was hit by flying lava that broke his leg.
