The Philippines was hit by a 6.3 magnitude earthquake on April 22, 2019 and there is some interesting video of high-rise buildings swaying and of water from a rooftop pool cascading down to the ground. See below! One minor expletive in English, so only minor NSF. Thanks to Jim Withiam for the heads-up on this one.
As a follow up to a previous post, the San Andreas Fault Observatory at Depth (SAFOD) team has announced that they have successfully completed their drilling and obtained cores of the San Andreas Fault at depths in excess of 2 miles below the surface. The zone of interest is approximately 135-ft in length. The core size is 4-in diameter. They have cemented in a 7-in casing and the next phase of the project will be to perforate the casing within the fault and install monitoring equipment consisting of seismometers, accelerometers, tiltmeters and a fluid pressure transducer.
