Honestly, it has been a busy day for the planet. If you felt a rattle or saw the curtains sway and immediately reached for your phone to check what was the magnitude of the earthquake today, you aren't alone. Seismographs have been pinging across several continents over the last 24 hours. While most of these tremors weren't "The Big One," they certainly remind us that the earth is constantly shifting beneath our feet.
The standout event today, January 17, 2026, occurred near Petropavlovsk-Kamchatsky, Russia, where a magnitude 5.3 earthquake struck at 06:46 UTC. It wasn't just a isolated blip either; the Kermadec Islands near New Zealand saw a 5.2 magnitude shake, and Japan’s Yonakuni region recorded a 5.0 magnitude tremor shortly after.
These aren't just numbers on a Richter scale. They represent massive shifts in tectonic plates that define our geography.
What Was the Magnitude of the Earthquake Today? Global Roundup
Usually, when people ask about the magnitude of the earthquake today, they are looking for that one "headline" event. Today, we actually had a series of moderate quakes.
- Russia (Kamchatka Peninsula): The 5.3 magnitude quake was relatively shallow at about 23 kilometers deep. This region is part of the Kuril-Kamchatka Arc, one of the most seismically active spots on Earth.
- Kermadec Islands, New Zealand: Clocking in at 5.2 magnitude, this one was much deeper—around 70 kilometers. Deep quakes like this often feel like a low, rolling vibration rather than a sharp jolt.
- Yonakuni, Japan: A 5.0 magnitude seaquake hit earlier this morning. Japan’s early warning systems are legendary for a reason; they have to deal with these almost weekly.
- California, USA: If you’re in the States, you might have felt smaller "micro-quakes." A 3.3 magnitude hit near Tres Pinos, and a 2.8 rattled Avenal.
Why the depth matters more than you think
You see a 5.3 and think "that’s big," but the depth is the real kicker. A shallow quake (like the one in Russia) sends more energy directly to the surface. It’s like hitting a drum right on the skin versus hitting it through a thick pillow. Deep quakes, like the one near New Zealand, lose a lot of that "punch" before the vibrations reach your living room.

The Oregon 6.0 Aftermath
It is worth mentioning that many people asking about the magnitude today are still feeling the "hangover" from yesterday’s 6.0 magnitude earthquake near Bandon, Oregon. That was a significant event.
When a 6.0 hits, the aftershocks can last for days or even weeks. Most of the smaller pings on the USGS (United States Geological Survey) map today are actually settling movements from that larger Oregon event. Seismologists often describe this as the crust "finding its new normal."
How we measure these shakes
We’ve basically moved past the old Richter scale, even though everyone still uses the name. Nowadays, scientists use the Moment Magnitude Scale (Mw).
Why? Because the Richter scale was kinda bad at measuring really large quakes. It would "saturate," meaning it couldn't tell the difference between a 8.5 and a 9.0 very well. The Moment Magnitude Scale looks at the total energy released—the area of the fault that slipped and how far it moved. It’s way more accurate for the big stuff.

Is today's activity "normal"?
In a word: Yes.
The Earth has about 500,000 detectable earthquakes every year. About 100,000 of those can be felt, and 100 of them cause actual damage. If it feels like there are more lately, it’s mostly because our sensor networks have gotten insanely good. We can now "hear" the Earth whisper in ways we couldn't twenty years ago.
Safety check: What to do when the floor starts moving
If you're in an area prone to these tremors, knowing the magnitude after the fact is great for trivia, but knowing what to do during is what matters.
- Drop, Cover, and Hold On: Do not run outside. Most injuries happen from falling debris or people tripping while trying to leave.
- Stay Away from Glass: Windows are the first things to go.
- Check Gas Lines: If you smell "rotten eggs" after a shake, get out and call the utility company.
Prepare for the next one
Since we know quakes come in clusters, now is the time to double-check your emergency kit. You’ve probably heard this a million times, but do you actually have three days of water? Most people don't.

Secure your heavy furniture. That bookshelf that looks fine? In a 6.0, it becomes a projectile. Use L-brackets to anchor tall furniture to the wall studs. It takes ten minutes and costs five dollars.
Keep an eye on the official USGS or EMSC (European-Mediterranean Seismological Centre) feeds for the most up-to-date data on what was the magnitude of the earthquake today in your specific zip code. These sites update within minutes of a strike and provide "Did You Feel It?" maps where you can contribute your own experience to the scientific record.
Download a reliable earthquake alert app. Many modern smartphones have built-in accelerometers that can give you a few precious seconds of warning before the S-waves (the ones that cause the real shaking) arrive. Those seconds are the difference between being under a table or under a falling light fixture.
