A magnitude 5.6 earthquake just struck directly beneath Mount Fuji — JMA puts the follow-up probability at 10-20% and the monitoring window at 7 days. The 1707 precedent took 49.

JMA confirmed no changes in volcanic monitoring data after the June 26th M5.6 at 20km depth near Fujikawaguchiko. The agency issued a standard one-week caution window citing 10-20% historical frequency of comparable follow-up events.

The part missing from most coverage: the 2012 NIED study estimated magma chamber pressure beneath Fuji at 1.6 MPa following the Tōhoku earthquake — 16x the 0.1 MPa threshold associated with the 1707 Hōei eruption, which occurred 49 days after the M8.6 Nankai earthquake, well outside the standard monitoring window.

New research confirms the supervolcano-style monitoring at Kīlauea has scientists watching the next 72 hours closely — 49 episodes and counting

Kīlauea has produced 49 fountaining episodes since December 2024 — more than any episodic eruption ever recorded at this volcano, officially surpassing the historic Puʻu ʻŌʻō sequence (47 episodes, 1983-1986) that eventually transitioned into a 35-year lava flow.

USGS's latest update has narrowed the forecast window for episode 50 to June 25-27, with June 26 flagged as most probable. That's not a guess — it's based on measured tiltmeter inflation and gas emission data at the summit.

New research confirms Naples' supervolcano has entered an accelerating phase — and nobody evacuated this time

Campi Flegrei sits directly beneath Naples — not nearby, underneath. 500,000 people live inside the caldera itself.

​

New research confirms the system has entered an accelerating phase, with deep magmatic volatile input now documented as an active driver. The historical precedent is 1538 — the last time this system produced a major eruption, the area was evacuated. This time, despite documented acceleration, there has been no equivalent response.

The Mediterranean entered its 2026 summer hotter than it entered 2025 — Copernicus data shows anomalies above 5°C in the western basin before summer begins

In 2025, marine heatwaves affected 99.6% of the Mediterranean Sea. The 2003 event — which took 70,000 lives across Europe — was the historical ceiling. The current data has already surpassed it in geographic extent, three consecutive years, each starting from a warmer floor than the one before.

July 2025 registered the warmest Mediterranean surface temperature since records began at 26.9°C. That is now the pre-season baseline for summer 2026.

Copernicus data shows the Mediterranean failed to reset for the third consecutive year — and the Atlantic inflow through Gibraltar is now amplifying the warming instead of moderating it

In 2025, marine heatwaves affected 99.6% of the Mediterranean basin. Second warmest year on record at 21.35°C — following records in 2024 and 2023. The basin is not fluctuating. It is climbing.

The mechanism that should be moderating this — Atlantic inflow through the Strait of Gibraltar — is currently importing heat. As of May 30, 2026, anomalies in the western Mediterranean already exceed 5°C above seasonal average before summer begins.

A Paris-Saclay attribution study processed against 74 years of ERA5 reanalysis confirmed long-term warming has amplified Mediterranean SST extremes by up to 1.5°C, with dominant anthropogenic contribution.

Kamb Ice Stream, West Antarctica, April 2026 — First in-situ measurements confirm volcanic and ocean heat sources melting the ice simultaneously. 138 volcanic systems with almost no monitoring.

In April 2026, a Cornell University team entered a subglacial channel beneath the West Antarctic Ice Sheet for the first time in history. Their instruments confirmed two simultaneous heat sources melting the ice from below — volcanic heat from upstream and ocean heat from the Ross Sea.

A second study presented at the Goldschmidt Conference establishes that as glaciers retreat, subglacial volcanoes don't stay dormant. They wake up and erupt more frequently.

There are 138 confirmed volcanic systems along a 3,000km rift beneath the ice. Almost none have real-time monitoring. The first in-situ measurement from any subglacial channel in the region was published four weeks ago.

2026 study places the Atlantic current inside stage one of a documented two-stage collapse process — the 53km drift is already in 30 years of satellite data

Utrecht University published the highest-resolution AMOC simulation ever completed in March 2026. It identified a two-stage collapse signature: stage one is a slow northward drift, stage two is an abrupt 219km lurch in just 2 simulated years followed by full conveyor failure.

They cross-referenced against real satellite altimetry (1993-2024) and subsurface observations back to 1965. The Gulf Stream has already drifted ~53km north — matching stage one exactly.

A separate Science Advances study from April 2026 revised the slowdown estimate from 32% to 51% by 2100. Rahmstorf revised his personal collapse probability from 5% to over 50%.
