An ⁠earthquake ​with ⁠a ⁠preliminary magnitude ​of ‌7.1 ‌struck ‌the country’s Kumamoto prefecture Japan’s prime minister, Takaichi Sanae, has confirmed that a tsunami advisory was issue for Ariake Bay and Yatsushiro Sea after the earthquake hit the Kumamoto prefecture. She wrote on social media: At around 4:27 p.m. today, an earthquake with its epicenter in the Kumamoto region of Kumamoto Prefecture occurred, and strong shaking with a maximum seismic intensity of 7 was observed in Uki City and Makigawa Town in Kumamoto Prefecture. In connection with this earthquake, a tsunami advisory has been issued for Ariake Bay and Yatsushiro Sea, and tsunamis of about 1 meter are expected. Please refrain from approaching the coast. From me, to the relevant ministries and agencies - Urgently grasp the damage situation - Closely coordinate with local governments, and under the policy of prioritizing human life, the entire government will fully engage in emergency disaster response measures such as lifesaving and rescue for the affected people - Timely and accurate provision of information to the public regarding tsunamis and damage, etc. I have instructed these three points. To those in the areas where the shaking was strong, I would like to ask you to continue to be vigilant against the occurrence of earthquakes of the same magnitude. Continue reading...

⚒️ 🧪 One week has passed since the M7.5 earthquake in Venezuela. FUNVISIS has detected >600 aftershocks so far, concentrated in the east, near Caracas. New satellite imagery shows >3 meters of likely surface offset in the same area - perhaps explaining the aftershocks, and contributing to damage.

Aftershocks and satellite imaging of the Venezuela earthquake

Early results show >3 meters of near-surface offset near Caracas, with a zone of intense aftershocks

NASA-ISRO SAR (NISAR) satellite imaged Venezuela June 25. NISAR SAR interferometry (InSAR) enabled calculation of surface displacement. Displacements have red tones for east and blue tones for west, with white in middle near-zero over fault rupture. Fault ruptured far to east under ocean. #venezuela

Map of north-central Venezuela with NISAR line-of-sight displacement map shown in false color varying from red to white to blue. Red land moved east (towards satellite) and blue land moved west. InSAR only measures land, so ocean and lakes have no measurements. Background map from Google satellite natural-color images on land and bathymetry in ocean.
