"Active faults of Japan" published last year. The book has detailed maps and descriptions of active faults of Japan islands, and comes with the access of an online GIS database.

Over the weekend, @planet.com captured almost perfect satellite imagery of the 4 November 2025 landslide at Mae Moh Mine in Thailand. eos.org/thelandslide...

Imagery from @planet.com has captured the 4 November 2025 landslide at Mae Moh Mine in Thailand. It shows the failure was about 4.8 km long and 1.4 km wide. There appears to have been coal waste dumping on the area that failed in the weeks before the landslide. eos.org/thelandslide...

The 12th ACES (APEC Cooperation for Earthquake Science) International Workshop in Taipei just finished! 🎉 203 scientists & experts from 21 countries gathered for the largest ACES meeting ever, sharing the latest in #EarthquakeScience. Relive the highlights: www.youtube.com/watch?v=eCPp...

For the Philippines, the latter half of 2025 has not been very peaceful in terms of earthquakes. A Mw 7.4 earthquake occured along the Philippine Trench this morning. Background Image source: Earth Observatory of Singapore.

Open faculty position! The Department of Geosciences at the National Taiwan University (NTU-TW) invites applications for a tenure-track faculty position. Details here: web.gl.ntu.edu.tw/index.php/re...

A LLOF (Landslide Lake Outburst Flood) event happened in eastern Taiwan on Sept 23, causing severe flooding in the downstream area. Despite warnings issued in advance, it killed 17+ people, mostly elders living in 1F. The image taken by Planet Lab today shows the affected area of this LLOF event.

If you are working on earthquake related research in the Pacific region, it's not too late to consider coming to the ACES workshop in Taipei, Taiwan this November.

Uplifted reels platform associated with the 2013 Bohol earthquake

The cave swimming pool in Bohol island, Philippines. People find many different usages to these limestone caves around the world

The change of earthquake swarm near Japan's Tokara islands, from JMA's website. Two clusters developed since the beginning of this episode of activity.

One year after the 2024 Hualien earthquake, the Taruko gauge is gradually coming back.

I thought the Myanmar earthquake was crazy, but actually, it's even more crazy than what I could imagine....

Uplifted oyster layer in the Hualien Harbor associated with the Mw 7.4 earthquake last year, eastern Taiwan

New observation deck in the Chelongpu fault trench muesum.

Here I am again. The Cheloungpu fault trench muesum, #Taiwan

We are going to have a special issue in TAO journal addressing the recent M6.4 earthquake in SW Taiwan. Check out more: link.springer.com/collections/...

Fluvial terraces aling the Dahan River, northern Taiwan. Several other levels of terraces have been inundated by the reservoir in this photo.

#Hokudan2025 is starting today online. Unfortunately we can't attend in person this time...

Today is the 30 yrs anniversary of the 1995 Kobe earthquake, the earthquake that advances our understanding of active faults and seismic hazard analysis around the world.

Don't forget that there are another 30+ active faults in Japan that have been classified as S class active fault. Other places could also be struck by hazardous earthquakes (like Noto eq last yr), in addition to the Nankai Trough mega earthquake.

This new paper by Yu et al. describes the recent progress of the tsunami deposit investigation in Taiwan. Although there are some debates about how to identify the tsunami deposit from the typhoon deposit, but surely there is some good evidence of paleotsunami here link.springer.com/article/10.1...

Let's take a look at some field photos showing the normal fault ruptures (Taken by field survey team of the Institute of Geology, China Earthquake Administration).

from @tectonicsyang.bsky.social: "Dr. An Li from our department reports on earthquake surface ruptures based on pre- and post-earthquake satellite images." www.eq-igl.ac.cn/zhxw/info/20...

Now China has enough high-res optical satellite to make timing observations after the earthquake. The following link is the news report in HK related to the damage assessment of the Tibetan earthquake. www.hk01.com/%E5%8D%B3%E6...

This paper describes the normal fault scarp associated with the recent earthquake in the Tibetan earthquake. This is one of the iconic papers of active fault study in that area.

The earthquakes around the Tibetan Plateau have a very distinct spatial distribution pattern. Below the Himalayas are reverse faulting related to Indian plate underthrusting. Underneath the Plateau are the normal and strike-slip related to the E-W extension and escaping.

Let the old and unhappy things go away, and let's wish a very new year of 2025

The footage of 2004 tsunami from the national geograpgy. I think this location is the Phukwt island. It's getting more difficult to find these footage even with the modern internet and social media. Humans are easy to forget things. youtu.be/iSOdNTnkKu0?...

On 7 December 2024 a large mine waste #landslide occurred at #Turmalina Mine in Brazil. Fortunately, those at risk had been evacuated. Once again, the #mining industry is responsible for a large failure. More details on the Landslide Blog: eos.org/thelandslide...

Likely to be another false event in Singapore?!

There is a famous layer named "Dancing Tuff" (Odori-tuff).

A catholic church in #Tainan, southwestern #Taiwan. The design is to blending with the local buildings (and culture), so it would be easily adapted by locals.

A false alert of earthquake in Singapore, but actually I wont be too surprised if this were a real event because indeed there were natural earthquake happened in this city state in history.

This aftershock is likely a triggered aftershock on an adjacent active reverse fault. The mapped seismogenic fault near the epicenter matches to the orientation of the aftershock focal mechanism, based on the NEID's data

Our department is running a student field trip for non-geology major students twice per year for almost 30 years in Taiwan. This is one of the iconic courses in our university. Lots of logistics, paperwork, and headache need to be taken care of by TAs and instructors, but the result is positive.

Korean colleagues + Yann Klinger from our #IPGP #Tectonics team have published a paper on the active Yangsan Fault in SW #Korea. They use zircon ages to identify drainage reversal and geomorphological changes. ⚒️ doi.org/10.1038/s415...

The Mw=7.6 8 October 2005 Kashmir Earthquake triggered the remarkable 68 million cubic metre Hattian Bala landslide in Pakistan. It is estimated that this failure killed about 1,000 people. More details at: eos.org/thelandslide...

The aftermath of Mw 7.2 Hualien earthquake in April this year. #Landslides and #debris flows are now the constant in eastern #Taiwan when heavy rain visits the strong shaked area.

This location used to be the datum #benchmark of #Taiwan. Because of that, the Taiwan datum used to be called "Hu Tze Shan" coordinate system. The monument has now been turned into a continuous GNSS station, and is one of the primary CORS ground control point of the island.

Interesting shallow crust earthquake between Taiwan and Luzon.

Abandoned mechanical house for the ski lift in the Mt. #Hehuan area, #Taiwan. Back to 70s and early 80s, there was an attempt to develop a ski resort in the Central Range of Taiwan. However, the plan fail because of the short winter season and the lack of frequent heavy snow.

A very nice-looking open fold in the slate belt at central #Taiwan. You can see vertical cleavages developed within this sandstone-shale formation

The real and the animated scene at #Daiba in the animation of "Tokyo Magnitude 8.0" . This animation describes the damage and human response AFTER an Mw 8.0 earthquake struck Tokyo. This is one of my favorite "Nat Hazards" stories on the screen.

Uplifted #coral #microatolls along the northern #Luzon island. These coral microatolls mark the paleo #sea-level before the subduction zone, or the upper plate earthquakes.

More than 4 meters of coseismic coastal uplift close to the northwest corner of the Noto Peninsula. The uplifted oyster line was once close to the MSL... #能登半島

Damage reported in Manzanillo, Cuba after the M6.8 earthquake...

The first snow on the #Hakusan this year. The snow is late everywhere in #Japan due to the change of climate. Lots of large-scale #landslides around the Mt Hakusan and some of them can be seen in this photo. #白山

Damages from the recent #Cuba earthquake.
