Webcam Time-Lapse of the Week — April 2026 Highlights

I pulled three hours of footage from the Kilauea cam after Tuesday morning’s eruptive pulse and built a 90-second time-lapse on the laptop while the next pulse was still going. There’s something about compressed time that the live cam doesn’t show — the rhythm, the structure, the way a 3-hour event reveals itself only at speed. That’s the case for this column. Live cams are for now. Time-lapses are for understanding.

This week’s highlights from the Port of Cams network — April 21 through 27, 2026.

Kilauea — Tuesday morning eruption pulse

Live frame from our Kīlauea South cam — the same cam the time-lapse was built from.

A 4-hour eruptive episode at Halema’uma’u Tuesday morning (April 22) HST. We caught the ramp-up around 4:50 a.m. through stable fountaining at 6:30 a.m. and the gradual taper afterward. The time-lapse compresses it to 90 seconds — fountain heights ranged 30–80 m at peak.

Worth watching for: the steam-to-fountain transition at the start, and the fan-shaped lava distribution as the episode peaked.

Alaska — Cleary Summit aurora 4/22

A modest Kp 5 event on the night of April 22–23 produced clean curtains over the Steese Highway corridor north of Fairbanks. The Cleary Summit cam caught about 90 minutes of clear curtains around 1:00 a.m. AKDT before clouds rolled in.

Not the year’s biggest show, but the cleanest curtains we’ve seen in this corridor in 2 weeks. As the solar cycle continues to be active through 2026, the math says we’ll get more.

Hawaii — Pipeline swell 4/24

A long-period north swell hit Oahu Thursday (April 24). Pipeline cam caught the morning glass-off — clean barrels with offshore winds from sunrise through about 9:30 a.m. HST.

The time-lapse compresses 4 hours of waves to 60 seconds. You can see the swell direction shift slightly throughout the morning, which the live cam doesn’t reveal at real-time speed.

Manhattan — sunrise from a 30th-floor cam

A reader-submitted cam (Murray Hill area, 30th floor) caught a clean sunrise on Wednesday with low clouds illuminating from below. The time-lapse runs 30 seconds for what was about 22 minutes of actual sunrise.

City cams don’t usually produce content like this. Worth bookmarking for atmospheric clarity.

The week’s quietest cam

This is the contrarian pick of the week. The quietest cam we ran was a Pacific Northwest creek cam in southern Washington. Same flow rate all week, same camera angle, same lighting cycle. Nothing happened — and that was the point.

Sometimes nothing happening is the show. We left it on for 4 hours one afternoon while doing other work. By the end, the constant low-volume water sound was so much in the background you’d forget it was there. Then a single eagle flew through frame for two seconds. We didn’t notice until we reviewed.
