So, the ground just shook again. Honestly, if you live on the Big Island, you’re probably used to the occasional rattle, but the earthquake Hawaii just now activity has people checking their chandeliers and USGS feeds a little more often than usual. As of January 15, 2026, we are seeing a cluster of seismic events that aren't just random bad luck; they’re the literal "aftershocks" of a massive volcanic event.
Specifically, the Hawaiian Volcano Observatory (HVO) is tracking swarms beneath the Kīlauea summit.
It’s been a wild week. Just three days ago, on January 12, Kīlauea’s Episode 40 sent lava fountains screaming 820 feet into the air. That’s nearly three Statues of Liberty stacked on top of each other. Now that the fountains have died down, the plumbing underneath the volcano is trying to find its balance. This is why you're feeling those shakes.
What is happening with the earthquake Hawaii just now clusters?
Most of the recent tremors are concentrated around Pāhala and the Halemaʻumaʻu crater. In the last 24 hours alone, there have been over 30 earthquakes recorded with a magnitude of 1.5 or greater.
The biggest one today? A magnitude 2.5 near Pāhala.

Now, a 2.5 isn't going to knock your house down, but it’s part of a persistent "buzz" in the Earth's crust. According to the USGS, a significant swarm started around 7:35 p.m. HST on Wednesday and lasted about 40 minutes. These aren't just tectonic plates grinding; they are "volcano-tectonic" earthquakes. Basically, when magma moves out of a chamber during a big eruption (like Episode 40), it leaves a vacuum. The rock above and around it then cracks and shifts to fill that space.
It’s like a giant underground house settling after the owners moved all the heavy furniture out.
The Numbers You Need to Know
- Today's Peak: 2.5 magnitude (Pāhala).
- Recent Depth: Most summit quakes are shallow, about 1 to 2 miles (1.5–4 km) deep.
- The Pāhala Exception: Deep quakes in the Pāhala region are often much further down, sometimes 20–25 miles deep, related to the magma transport system feeding the whole island.
- Alert Level: Currently stays at WATCH, with the aviation color code at ORANGE.
Why does Pāhala keep shaking?
If you look at the map of the earthquake Hawaii just now data, Pāhala looks like a target. It’s one of the most seismically active places in the United States. Why? Because it sits right above the "magma superhighway."
Scientists like those at the Hawaiian Volcano Observatory have studied this for decades. They believe there’s a complex web of sills—horizontal sheets of magma—deep under the district. As magma pushes up from the mantle plume (the hot spot), it puts immense pressure on the crust.

You’ve got the weight of the massive Mauna Loa and Kīlauea volcanoes pushing down, and the magma pushing up. Something has to give. That "giving" is the constant drumbeat of small quakes.
Should we worry about a new eruption?
This is the million-dollar question.
Usually, when we see earthquake swarms, we think "magma is moving, an eruption is coming." But right now, the experts aren't sounding the alarm for a new area. The HVO noted that the recent swarms are likely "internal pressure adjustments" following the rapid withdrawal of magma during the January 12 fountaining.
Here is the nuance:
A small swarm did precede the opening of a new fissure during Episode 30 last year. So, while the current shakes are likely just the volcano "exhaling," the USGS is watching the tiltmeters very closely. If the ground starts bulging (inflation) at the same time the earthquakes pick up, that's when you grab your "go bag."

Currently, the rift zones—the areas where lava usually breaks out toward communities—remain quiet. Everything is staying contained within the Kīlauea caldera for now.
Actionable steps for residents and visitors
If you’re on the island and the earthquake Hawaii just now activity has you uneasy, there are a few practical things you should actually do.
- Secure your "T-rex" items. We all have those tall, skinny lamps or top-heavy vases. Use museum wax or "quake putty" to stick them down. It sounds overkill until a 4.0 hits at 2 a.m.
- Check the HVO Daily Update. Don't rely on Facebook rumors. The USGS Hawaiian Volcano Observatory posts a daily text update around 8:00 or 9:00 a.m. HST. That’s the gold standard for info.
- Monitor the "Did You Feel It?" reports. If you feel a shake, report it on the USGS website. Your data helps seismologists map how the ground moves in specific neighborhoods, which improves future safety building codes.
- Mind the vog. Earthquakes and eruptions mean sulfur dioxide. If the wind shifts to a "Kona wind" pattern, that volcanic smog (vog) will head toward Kona and West Hawaii. Keep your inhalers handy if you have asthma.
The Big Island is a living organism. These shakes are just its way of breathing. Stay informed, keep your gas tank at least half full, and enjoy the show from a safe distance.
