The ninth cycle began at 12:04 pm HST and by 12:09 was overflowing the vent. The volume of overflows continued to increase producing flows that began spreading into Haleamaʻumaʻu. Drainback began at 12:17 pm HST terminating the flows.

The seventh and eighth cycles took place from 11:27 to 11:37 and 11:45 to 11:53 am HST. The eighth cycle had a small spillover of lava that went to the base of the north vent rampart.

The sixth magma rise and drainback cycle happened between 11:07 and 11:18 am HST with a wee amount of lava spilling out of the vent. The onset of episode 14 on March 19 was preceded by 9 hours of sporadic cycles with some minor lava flows.

The fifth cycle of magma rise, fountaining, and drainback began at 10:48 am HST and ended at 10:58 am HST on March 25. All magma has remained within the north vent at this time.

A second cycle of dome fountaining and drainback in the north vent started at 9:55 and ended at 10:02 am HST. All activity remains confined to the vent, but the level of magma rose near the lip of the north cone.

Small dome fountains 20-30 feet high became visible in the north vent from 9:27 am HST to 9:33 am HST. Lava was confined within the cone at this time and is a prelude to the onset of episode 15.

The UWD tiltmeter is not currently providing reliable data. HVO staff are working to resolve this issue. In the meantime, the SDH and IKI tiltmeters remain operational.

The earliest episode 15 might start is very late tonight March 24 or in the wee hours of Tuesday March 25 if current inflation rates continue. If inflation rates slow, the onset of episode 15 may be delayed by a day.

Episode 15 is now most likely to start late today (Monday, March 34) or tomorrow due to the lack of summit inflation over the past 24 hours. Additional revisions may be necessary if inflation rates remain low.

Episode 15 of the ongoing Halemaʻumaʻu eruption is likely to begin late today (Sunday March 23) or tomorrow morning (Monday March 24) with a wee chance of being delayed to Monday night.
