Kīlauea Eruption Update, Day 45: February 3, 2021

3:04 AM · Feb 4, 2021

Still little change with Kīlauea volcano's ongoing summit eruption, though a deflation cycle has begun today, portending changes in the coming days: New: - Crater filled with lava to a depth now at 213 m / 699 ft deep - Filling slows as a deflation cycle appears on monitoring signals - Kona winds blow vog to east Hawaiʻi - Historical perspective on magma supply rates As usual, we review the latest publicly available USGS Hawaiian Volcano Observatory data & imagery while providing geologic context and annotation. In today's historical perspective, we circle back to the issue of magma supply rates to Kīlauea volcano for the past 200+ years in order to put the current activity into better context.
