A M6.9 earthquake struck Cebu island in the Philippines today, causing at least 20 deaths.

The rupture seems to have occurred on an unmapped fault, started below the ocean and continuing to the southwest, passing near populated areas of Cebu.

Confirmed, I will be in the area then! Well San Francisco and Auburn anyway.
Can't wait (and yes everything crossed for a very seismically uneventful trip!).

I have no words, never knew these photos existed!!! @davepetley.bsky.social have you seen them?

Mount St. Helens in 1980 @mountsthelens1980.bsky.social · 18d

If you know what you're looking at, these become three of the most insane, unbelievable photos you'll ever see.

The luck that put three people in this spot, to capture the largest landslide in recorded history from this vantage point.

Oh, and capturing the lateral blast's start, too, in the last.

Aerial view of the initial north flank landslide on Mount St. Helens. Slide blocks from the bulge drop away and a gray dust sheet rides downslope toward the forested valley and clearcuts. Dorothy Stoffel. May 18, 1980. About 8:32–8:33 a.m.

Wider view of the debris avalanche accelerating off the north side. Elongate slide blocks and fresh scarps stripe the slope as a ground-hugging dust cloud marks the moving mass into the North Fork Toutle valley. A small plume of ash and steam appears at the bottom-right margin. Dorothy Stoffel. May 18, 1980. About 8:33 a.m.

Close oblique near the scarp. Jets of ash and steam punch through the collapsing rim while dense dust clouds boil from the disintegrating avalanche spilling off the north flank. May 18, 1980, about 8:33 a.m. Dorothy Stoffel.

Satellite map of the area showing the location of the earthquake epic center marked by a star. There are also different colors on the map that indicate the different levels of shaking. The shaking is most significant to the east of the epic center.

Interestingly I may be in the Sacramento area next April. I hope not to bring my curse with me so your guy doesn't have to worry.

Tell him to call me. I have lived in Christchurch 12 years (so not including 2010-11) & in that time I have felt:
- 1x 7.8
- 2x 6.5/6.6
- 1x 6.1
- 1x 5.8 (max local event)
- Several around 4.7-4.2 including one 1 mile from home
- Dozens of 3s
Sacramento is closer to your plate boundary than we are.

The shallowest landslide I think I've ever seen and seems tragic too with cars on the road at the time. @davepetley.bsky.social what do you make of it?

Just found out about the discontinuation of the stratospheric temperature and height products from the NOAA POES satellites. I did not think to link these to recent political changes to US satellite operations.

I am deeply dismayed by this. Our understanding of the stratosphere is now hamstrung.

The M6.1 shallow #earthquake near Bigadic, Turkey, occurred on a normal fault system, possibly the Sindirgi-Sincanli Fault Zone. A similar event occurred near Simav in 2011 and generated significant damage around the epicenter. ⚒️🧪

This. 8.8 to 8.9 is a big difference, 8.9 to 9.1 big again, 8.9 to 9.1 is an enormous energy difference. Magnitude 9 earthquakes are truly colossal events.

Dr Robin George Andrews @squigglyvolcano.bsky.social · Jul 30

NEW: You may wonder why Japan’s 2011 mag-9.1 quake created a colossal tsunami that killed 18,000 people, while today’s mag-8.8 quake made a big, but not catastrophic, tsunami.

For @sciam.bsky.social, I explore why. (Hint: it’s because the 2011 quake was SO much stronger.)

Andrea Thompson @andreatweather.bsky.social · Jul 30

Another earthquake story from @sciam.bsky.social by the always-excellent @squigglyvolcano.bsky.social explaining why the tsunami from the Russia quake wasn't as huge as the one from the 2011 Japan quake, for example. 🧪

Meanwhile in NZ we have an advisory for unusual strong currents and surges but no tsunami warning, thankfully.

There's the main event then! Got to be devastating for Kamchatka's coastal communities.

Dr. Alice-Agnes Gabriel @inseismoland.bsky.social · Jul 30

Magnitude 8.7 #earthquake in Kamchatka, following a M7.4 last week - may be largest earthquake since 2011, 8th largest on record globally, #tsunami warning in place for US west coast and Canada - the historic 1952 M9 closely caused a destructive tsunami across the Pacific

Explains the shallow aftershock depths to some degree, and very interesting on a range of topics!

⚒️ 🧪

A M7.4 earthquake just struck Russia's Kamchatka peninsula - near where a M7.1 occurred last year. After that quake, we explored the idea of a megaquake advisory, like we’d seen in Japan. What does this new earthquake tell us about megaquake advisories, as a concept?

Some intense aftershock action for this one at depths shallower than the mainshock, at least at a glance.

I also derived a new elevation model from the aerial images, allowing me to visualize the elevation change in the affected areas.
The rocks and debris in the valley are locally up to 32m thick and I estimate the total displaced volume is about 11 million cubic meters. #Blatten

Map of the Lötschtal showing the area affected by the glacier collapse.
Blue colors show lost elevation, red areas elevation gains.
The two most notable areas are the collapsed peak of Kleines Nesthorn and the collapsed glacier which are shown in deep blue with elevation loss of up to 128m and 51m respectively.
The material slid down the mountain in an approximately 400m wide path and accumulated in a 2,5km long area on the valley floor which is up to 32m thick.
The newly formed lake above the village of Blatten is also drawn in.

The Map text reads:
Kleines Nesthorn and Birchgletscher collapse / Blatten im Lötschental (VS)
On Wednesday, May 28th, a2025, the Birchgletscher glacier collapsed under the weight of rock and debris following the partial collapse of the Kleines Nesthorn.
Approximately 10 million cubic meters of debris flowed into the valley, burying large parts of the villages of Blatten and Ried. The debris also blocked the Lonza River, forming a small lake that destroyed several more houses in Blatten.
Analyis
Using Oblique imagery collected and provided by swisstopo on May 30th, 2025, a photogrammetric DEM was created and compared to the swissALTI3D DEM.

The following volume change was measured in the affected area:
Above Volume (m³): 11.2 Mio
Below Volume (m³): 10.1 Mio
