Heard about power outages & landslides in #Hokkaido. Level 6 intensity on JMA’s scale out of a max of 7. Thankful for their english webpage which presents the information in an easy to digest format. Praying for the affected!#GeohazardsNCP18 @scienceANU @anuearthscience @ANU_CPAS pic.twitter.com/XwTAkOQijh

Yesterday’s lecturer, Prof Kenji Satake, talking on tv about the 6.7 magnitude earthquake that hit #Hokkaido this morning. Very sad to hear of the destruction it has caused, including a landslide in the town of Atsumi. Geohazards feeling very real! #GeohazardsNCP18 pic.twitter.com/RwMweKDGCU

The 40km quake is quite shallow,heavy shaking rendered ~3000000 homes in Abira and Chitose now without power.Visited Chitose 4 years ago,hard to stomach the fact that this pleasant town had to suffer a quake😥 #北海道地震 #GeohazardsNCP18 @scienceANU @anuearthscience @ANU_CPAS

Stratigraphic sample taken from the Sendai plain, it shows evidence of previous tsunami events (2011, 1611 and 869) along with a volcanic eruption (white layer from 915). Also shows a clay layer @ bottom when the area was underwater #geohazardsncp18 @anuearthscience pic.twitter.com/x8jvELorN9

Who knew that cross-sections of earth could tell us so much about the past? Although it looks unassuming, this slab from the Iwanuma Library is over 1000 years old and documents evidence of past tsunamis and geological disasters, and even human activity. #GeohazardsNCP18 pic.twitter.com/irCjtSEH3U

Today we visited Miyagi City Library and observed a small cross-section showing layers of deposition that taught us about past tsunami and volcanic events. It's amazing how much dirt can help us reconstruct past conditions! #GeoHazardsNCP18 @anuearthscience @ANU_CPAS @scienceANU pic.twitter.com/APl2rxJEXA

宮城の岩沼市民図書館にて。東日本大震災の津波によって運ばれた堆積物を含む、貴重な地層（をはぎ取ったもの）が展示されています。泥の上に乗った厚い砂の層が津波堆積物。同様の層が下層にも見られ、昔の津波の記録であると考えられています。 @ANU_CPAS @anuearthscience #GeohazardsNCP18 pic.twitter.com/wHlzLMJM2s

岩沼図書館に展示されている津波堆積物の剥ぎ取り標本。 もともと田んぼだった地表に津波で運ばれた砂が、プラスチックなどの人工物を伴って約20cm堆積しているのがわかります。 下位には1611年の慶長津波、915年の十和田火山噴火の火山灰、869年の貞観津波も記録されています。 #GeohazardsNCP18 pic.twitter.com/0UTAXUrK7I

Can you see the shore? Because in 2011, the tsunami reached all the way to this main highway! We’re off to the Onagawa field research Center to discover the long term effects of the tsunami of 2011 🌊 #geohazardsncp18 #japan pic.twitter.com/kvdxX65tfX

After the 2011 tsunami 75% of Onagawa was completely destroyed & today we learned just how resilient & efficient the Japanese are even after such devastation...very eye-opening to hear firsthand what it was like #GeoHazardsNCP18 @scienceANU @anuearthscience @UTokyo_News @ANU_CPAS pic.twitter.com/KJieOnoZCW

This didn’t exist 8yrs ago. It has been rebuilt after the #Tohoku tsunami. Onagawa is a town showing strength after crisis💙 #GeoHazardsNCP18 pic.twitter.com/KA5UADxX8w

Learning about the effects of the 2011 tsunami on the bay town of Onagawa. Once built next to the water, the town is now situated on artificial hills after rebuilding the 75% of buildings that were destroyed. A beautiful town with a sad history #GeohazardsNCP18 pic.twitter.com/AlHcc2jdgA
