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, 4 volcanoes are above normal background activity, according to the U.S. Geological Survey’s observatories:

| Ahyi Seamount | Advisory / Yellow | No signs of unrest in satellite data; no significant geophysical signals.[8] |
| Kilauea | Advisory / Yellow | The Halema'uma'u eruption of Kīlauea remains paused following episode 55 on October 17. The forecast for episode 56 fountaining is now Nov. 3-10, 2026.[9] |
| Shishaldin | Advisory / Yellow | Low-level unrest continues.[7] |
Alert levels run Normal, Advisory, Watch, Warning. Aviation codes run Green, Yellow, Orange, Red.
4. Sinkholes
We found no new news reports of sinkholes opening in the past 24 hours.
Official Telegram video: Russia's Emergencies Ministry (MChS), official Telegram channel, October 31, 2026 — “Ледяной хищник Даже несколько шагов по непрочному льду могут обернуться трагедией. Оказавшись в ледяной воде, человек быстро теряет силы, а намокшая одежда затрудняет движения. В такой ситуации счет может идти на минуты.” Topic: sinkhole. Caption in Russian. Picked by hazard keywords in the channel’s own caption. Telegram only plays this file in its app: use the button above.

Other natural-hazard video from the past day, from news organizations:
Video: CBS News, November 1, 2026 — “Watch: Thousands flood streets in cost of living protests across Italy #shorts”. Also in the news. Picked because its title names a natural hazard; it may not be covered in the data above.
Video: AccuWeather, October 31, 2026 — “The most adorable tornado costume you'll ever see!”. 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.
“Thunderstorms associated with severe wind gusts and a tornado threat are expected this evening into tonight from parts of New Mexico northeastward into the southern High Plains. A more isolated severe threat will be possible in parts of the Desert Southwest this afternoon.”
— NOAA Storm Prediction Center[5]
“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 M6.0 quake[10]
“Lava continues to erupt slowly within the summit crater of Great Sitkin Volcano. No earthquakes were detected at the volcano over the last day. Clouds obscured both satellite and webcam views of the volcano.”
— Alaska Volcano Observatory, on Great Sitkin[7]
“Small plumes of discolored water were seen in the ocean above Ahyi on October 16 and 21 this past week. Discolored greenish water was visible drifting several hundred meters from the summit of Ahyi. These plumes are likely associated with degassing and hydrothermal activity at the summit of the underwater volcano.”
— Northern Mariana Islands, on Ahyi Seamount[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[11]
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.[12]
- 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.[13]
- Earthquakes: Drop, Cover and Hold On.[14]
- Download the checklist: Be Ready: Earthquakes, Volcanoes, Extreme Weather and Sinkholes (PDF), with today’s active hazards first.
