@ai6yr Though an M7.6 quake is big for its effects on land, it's on the small end for causing tsunamis. When we see news like this, keep in mind a rule of thumb for estimating #tsunami risk from undersea #quake magnitude:
M7+ -> localized tsunami possible
M8+ -> regional tsunami likely
M9+ -> ocean-crossing tsunami expected

Another cool thing about Providence Canyon is there’s glitter and rainbows everywhere. At first I thought the rainbow water at the bottom for canyon was gasoline runoff but then noticed it was more concentrated wherever there was granulated mica. I looked it up, and when mica breaks down finely enough, it creates this rainbow swirl in water. Higher up in elevation, I also found some sandy yellow micaceous #clay.

🧵 As of Dec 5 we reached "last core on deck", so here's a brief update.
First things first: we enjoyed beautiful sundowners, but also had to go into WOW (‘wait on weather’) due to strong winds and high waves. Luckily, I don’t get seasick.
The scientists are very busy with sampling. In total we drilled 5 holes and recoverd 367 meters of core. In one of the holes we reached the max depth of 178 meters below seafloor, remember: in 7608 meters water depth. Expedition successful.

📢 One sound that becomes part of everyday life here is “core on deck”, which is announced every time a core arrives. Under normal conditions, one core takes about four hours to be retrieved.
Listen to it below. :)
The laboratories run 24 hours a day, and the scientists work in 12-hour shifts.
During visual core description, several tephra layers have been identified. These are traces of past volcanic eruptions and are important for age constraints.

We visited Providence Canyon State Park in #Georgia for my birthday, which was on Thursday. The park has a disturbing origin story but the beauty of the strata below is undeniable. Earth is the original work of #art from which all of the art we create is derived. The last time we saw this many earthen colors was in New Mexico last year. Here, the soil is mostly sand, not clay but there was still some #clay present. #nature #geology
Selected through an international call for science communicators, I’m working alongside an international team of scientists from #geology and #microbiology. Operated by JAMSTEC/MARE3, the Chikyu is coring sediment from more than 7,600 m water depth in the hadal zone. These cores help uncover megathrust earthquake and tsunami histories, and offer new insights into deep-sea trenches, the #carbon cycle, and #climate.

Wow. This is spectacular. A drone flight video in HD to the top of the Matterhorn in the Alps.
With several groups of climbers being passed along the way.
I felt a bit queasy in bits. I’m not good with heights.
