2. Earthquakes
The USGS recorded 14 earthquakes of magnitude 4.5 or greater in the past 24 hours.[6] The strongest:

PAGER is the USGS estimate of likely deaths and damage: GREEN means little or none expected, RED means extensive. A dash means none was issued.
3. Volcanoes
In the United States, 5 volcanoes are above normal background activity, according to the U.S. Geological Survey’s observatories:
| Volcano | Alert / aviation code | Latest word from scientists |
|---|---|---|
| Great Sitkin | Watch / Orange | Slow eruption of lava within the summit crater continues.[7] |
| Kilauea | Watch / Orange | The north and south vents had strong glow and flames overnight and south vent spattered at least once. There has been no reactivation of the September 30–October 1 intrusion. There is no anomalous activity outside of the summit.[8] |
| Ahyi Seamount | Advisory / Yellow | No plumes seen in satellite images; no significant geophysical signals.[9] |
| Gareloi | Advisory / Yellow | Activity remains at background levels.[7] |
| Shishaldin | Advisory / Yellow | Low-level unrest continues.[7] |
Alert levels run Normal, Advisory, Watch, Warning. Aviation codes run Green, Yellow, Orange, Red.
4. Sinkholes
No government agency publishes a live national sinkhole feed, so these come from today’s local news:
- Breaking News, Latest News and Videos reports, “’It was supposed to be the forever home’: 6 years after old mine caused sinkhole, homeowners remain in limbo ABC News investigates cases of dangerous sinkholes caused by abandoned mines.”[10]
- Orlando, Florida: WKMG reports, “ORLANDO, Fla. – Several residents have been displaced after a deep sinkhole opened beneath the back of a townhome in Orlando’s Villas of Costa Del Sol neighborhood, prompting the city to condemn two homes and bar residents from returning.”[11]
- Slate Belt: LehighValleyLive.com reports, “A sinkhole has caused a partial road collapse on Route 512, also known as Market Street, in Bangor.”[12]
Also in the News
Other natural-hazard video from the past day, from news organizations:
Video: ABC News, October 6, 2026 — “Start Here Oct. 6 | Supreme Court’s New Term: Wildfires & ‘Zombie Forests’”. Also in the news. Picked because its title names a natural hazard; it may not be covered in the data above.
Video: Sky News, October 6, 2026 — “Torrential rain floods streets in Catalonia”. Also in the news.
5. What the Experts Say
These are the words of the scientists and forecasters who watch these hazards for a living, quoted exactly.
“Satellite imagery indicates that Rachel’s convective structure has degraded over the past several hours. The eye has become obscured, while the surrounding deep convection has weakened, particularly over the western semicircle. The latest subjective Dvorak intensity estimate from TAFB was T4.5/77 kt, which is in good agreement with the latest objective estimates. Given these data and the continued degraded satellite presentation, the initial intensity is lowered to 75 kt.”
— Forecaster Gibbs, National Hurricane Center, on Hurricane Rachel[13]
“Severe storms are unlikely today.”
— NOAA Storm Prediction Center[4]
“The eastern margin of the Australia plate is one of the most sesimically active areas of the world due to high rates of convergence between the Australia and Pacific plates. In the region of New Zealand, the 3000 km long Australia-Pacific plate boundary extends from south of Macquarie Island to the southern Kermadec Island chain. It includes an oceanic transform (the Macquarie Ridge), two oppositely verging subduction zones (Puysegur and Hikurangi), and a transpressive continental transform, the Alpine Fault through South Island, New Zealand.”
— U.S. Geological Survey, “Seismotectonics of the Eastern Margin of the Australia Plate,” on the region around the M5.0 quake[14]
“Lava continues to erupt slowly within the summit crater of Great Sitkin Volcano. Minor earthquakes were detected in the past day. No activity was observed in cloudy satellite and webcam images over the past day.”
— Alaska Volcano Observatory, on Great Sitkin[7]
“There was strong glow and flames from north and south vents overnight, and south vent spattered at 1:19 a.m. H.S.T. this morning. The summit intrusion that happened the night of September 30 to October 1 has not reactivated.”
— Hawaiian Volcano Observatory, on Kilauea[8]
“Sinkholes are common where the rock below the land surface is limestone, carbonate rock, salt beds, or other rocks that can naturally be dissolved by groundwater circulating through them. As the rock dissolves, spaces and caverns develop underground. Sinkholes are dramatic because the land usually stays intact for a while until the underground spaces just get too big.”
— U.S. Geological Survey Water Science School, on why sinkholes form[15]
How to Prepare
- Keep a basic kit: water (one gallon per person per day for several days), food, a battery or hand-crank radio, a whistle, a dust mask and phone chargers.[16]
- Get alerts: Wireless Emergency Alerts need no sign-up; the FEMA app, NOAA Weather Radio, the USGS Earthquake Notification Service and the USGS Volcano Notification Service are free.
- Floods: Turn Around, Don’t Drown. Six inches of moving water can knock you down, and one foot can sweep a car away.[17]
- Earthquakes: Drop, Cover and Hold On.[18]
- Download the checklist: Be Ready: Earthquakes, Volcanoes, Extreme Weather and Sinkholes (PDF), with today’s active hazards first.
