Emergency earthquake water refreshed and hopefully never to be used! 🧪

⚒️ 🧪 Another big addition to the remarkable M8.8 earthquake sequence offshore Kamchatka: a M7.8 - the biggest aftershock so far. With foreshocks, aftershocks, aftershocks of foreshocks, and foreshocks of aftershocks, it's hard to keep these earthquakes straight! Read more about what's going on:

15 years ago, 4 Sep 2010 at 04:35 NZST the Mw 7.1 Darfield earthquake struck the Canterbury region of New Zealand, ~10 km SE of the town of Darfield and 40 km west of Christchurch, New Zealand’s 2nd largest city. It caused significant damage with intensity up to MM 9. 1/ 🧪

The Nelson-Tasman region of New Zealand is a rugged region in the NW corner of the South Island. The region has low levels of crustal seismic activity; however, it is home to two of the most significant NZ crustal earthquakes of the last century (more on these below). 1/ 🧪

August 21, 1949 - a damaging M8.1 #earthquake (one of the largest ever recorded in North America) struck off #HaidaGwaii. Shaking was so strong that it was hard to stand. Felt across most of #BritishColumbia, parts of Alberta, WA, Yukon and Alaska www.earthquakescanada.nrcan.gc.ca/historic-his... ⚒️🧪

76 years ago tonight - a M8.1 #earthquake off #HaidaGwaii ruptured a 500-km-long segment of the Queen Charlotte Fault ("Canada's San Andreas Fault"). The average slip along the #fault was ~5 m. Shaking was so strong that it was hard to stand. More than 100 aftershocks were felt on Haida Gwaii. ⚒️🧪🇨🇦

Why does tectonically “stable” Australia get earthquakes? @deeninis.bsky.social, Abbas and I explain in our new article for The Conversation. theconversation.com/why-does-aus...

This morning's magnitude 5.6 earthquake is the largest to have occurred in southeast Queensland since the magnitude 5.6 earthquake off Fraser Island in 2015. The Fraser Is quake was followed by magnitude 5.4 and 5.2 aftershocks in the following days, a reminder that further large events are possible

M 4.9 earthquake widely felt along the SE coast of the North Island. At this location and depth, I suspect normal faulting in the subducting plate. 🧪 Moderate earthquake occurred 20 km south of Hastings: geonet.org.nz/quakes/2025p...

⚒️ 🧪 A satellite took a picture of the tsunami as it crossed the ocean! And other things we’ve learned about the M8.8 Kamchatka earthquake - the sixth large earthquake ever recorded. earthquakeinsights.substack.com/p/updates-on...

This looks consistent with (official) reports of 10-20 m run-ups in Kamchatka/Okhotsk. With complex topo/bathy short wavelength features like the waves seen here can develop and superimpose on the long period tsunami. We've seen this in other places. Time will tell if this can be verified

During a tsunami warning we always caution that a tsunami arrives as a series of waves and the first arrival is not always the largest. Larger tsunami arrivals can occur hours later. We can see this from the recent M 8.8 Kamchatka earthquake.🧪

Looks I've gained a bunch of new followers - thank you! Unfortunately, I'm not the best person for quick updates on events like the Kamchatka earthquake as I'm part of the response team in New Zealand and get very busy. We spent the day assessing the tsunami threat and advising the government... 1/

The end of an era today! GNS Science has merged with NIWA (National Institute for Weather and Atmosphere) to become Earth Sciences New Zealand. Strange to technically no longer be an employee of GNS after many years, but looking forward to what the new organisation can provide for New Zealand.

Cook Strait separates the North and South Islands of New Zealand and has numerous faults that cut through it. Faults from the northern end of the Marlborough fault zone extend into Cook Strait. It also sits at the southern end of the Hikurangi subduction zone. 1/ 🧪

Watch the ground break and move during the magnitude 7.7 #Myanmar #earthquake. This footage shows the incredible power of the earthquake that devastated parts of Myanmar and #Thailand. My thoughts are with the people impacted by this event. 💔 🧪⚒️

The next region in New Zealand I’ll look at is the Wellington region. Wellington is the New Zealand capital, and the greater Wellington region has a population of ~430K, third largest in the country behind Auckland and Christchurch. 1/ 🧪

🧪⚒️ Two large earthquakes - M6.2 and M6.8 - occurred south of New Zealand yesterday, 1000 kilometers and 97 minutes apart. Coincidence, or something more? We explore the question of earthquake triggering in our latest post. earthquakeinsights.substack.com/p/m62-and-68...

Had a Mw 4.0 (ML 4.2) earthquake near Upper Hutt last night with nearly 4000 felt reports www.geonet.org.nz/earthquake/2.... The epicentre was only about 5 km from our place, but we slept through it! 1/ 🧪

📣PRESS RELEASE FOR NEW #BSSA PAPER📣 New research found 3 upper plate faults along New Zealand's Hikurangi margin. Should they rupture together or in sequence, devastating earthquakes could result. ⚒️ Press release: www.seismosoc.org/news/cluster...

My old office! Wonderful place to live and work - highly recommend it to anyone interested and qualified!!

The Geological Survey of Canada (Pacific Geoscience Centre near Victoria, BC and Vancouver, BC) has an opening for a research scientist in Earthquake Seismology. Join a great, diverse team doing cutting edge science. ⚒️🧪 Details: emploisfp-psjobs.cfp-psc.gc.ca/psrs-srfp/ap... Apply by 25 April, 2025

🧪⚒️ Two days after the M7.7 earthquake in Myanmar, what have we learned? Rapid seismological analyses shared by scientists suggest that the rupture was both longer and faster than expected - two factors that could have increased damage. Read more: earthquakeinsights.substack.com/p/updates-on...

Over the day, USGS significantly updated the ShakeMap which better represents the intensity along the ruptured fault now. ⚒️🧪

First slip map for the Mw 7.8 Myanmar earthquake. Propagation of rupture towards the South. Slipnear method (Géoazur/OCA).

Oooof. A massive earthquake at shallow depth pretty much right beneath Mandalay - Myanmar’s second largest city - that has a population of 1.6 million people. This country has gone through so much terrible upheaval over recent years - today’s earthquake could well be catastrophic

M 4.4 earthquake felt widely across the SW coast of the North Island, Wellington region, and east to the Wairarapa region. Nearly 8900 felt reports with shaking intensity MMI ~3.5 (weak shaking) in the epicentral region. However, we received > 700 moderate and strong felt reports. 1/ 🧪

🧪⚒️ A M6.8 earthquake struck offshore New Zealand's South Island yesterday. Fortunately, shaking was not damaging, and the associated tsunami was quite small (~10 cm). The earthquake occurred along the enigmatic Puysegur Trench. Was it caused by slip on the megathrust? We take a look.

A shaky morning for the South Island with a Mw 4.5 (ML 5.1) earthquake in the central South Island (North Canterbury) and two earthquakes (Mw 4.2 and 4.4) along the west coast near the town of Haast within an hour.

That was quite the shake here in #Victoria 🇨🇦 at 05:02 PT. M4.6 near Orcas Island, 45 km ENE from Victoria and 70 km from Vancouver. Felt all across southwest BC and northwest WA. Details and to report shaking: www.earthquakescanada.nrcan.gc.ca/recent/2025/...

That was a shallow M5.1 earthquake, 24 km NNE of Sechelt and 60 km NW of Vancouver at 1:26 p.m. PT. Shaking was felt by 1000's across southwest British Columbia. Details/report shaking: www.earthquakescanada.nrcan.gc.ca/recent/2025/... ⚒️🧪

The next region in the New Zealand I’ll look at is the Whanganui region along the west coast of the North Island, north of Wellington. The main population centres in the region are Whanganui and Palmerston North (~50K – 100K). 1/ 🧪

On 28 January (UTC) we had a nice shake in the lower North Island from a Mw 5.0 (ML 5.4) earthquake. It was 10 km east of the town of Eketahuna and ~120 km NE of Wellington. www.geonet.org.nz/earthquake/2.... 1/ 🧪

Since Geonet aren't here yet I'll do the honours: "A late evening M5.4 shake occurred in the Wairarapa at 11:26PM and was felt widely by those in the lower and central North Island. We have received over 23,000 felt reports. For more detail 👇 www.geonet.org.nz/earthquake/2...

Nice little jolt at our house. Given the location and depth it was likely normal faulting in the subducting Pacific plate. Strong earthquake occurred 10 km east of Eketahuna: geonet.org.nz/quakes/2025p...

325 years ago tonight (9 p.m. Jan. 26, 1700) a M~9 Cascadia subduction earthquake rocked the west coast from #VancouverIsland to northern California.
