Tune in to ⁦@KSEE24 + @CBS47 all day for a telethon benefiting Western Wildfire Disaster Relief. Today, Central Valley @RedCross Board Member, Thilani Grubel, described what it’s like to volunteer at the shelter & she shared stories of serving shelter clients during the #OakFire

Earthquakes beneath the ocean, and the tsunamis they cause, are some of the most destructive and deadly natural disasters. Undersea cables could help detect them. nyer.cm/3Dm2tC3

Today's quakes are near the 1981 Westmoreland earthquake, M5.8. That sequence had 10 quakes M≥3.5

The swarm happening now south of the Salton Sea, near Westmoreland is over 30 km south of the end of the San Andreas. It is in the Brawley seismic zone, a common source of swarms. So far largest is M4.4. Too far from the San Andreas to change the probability of a quake on it.

You can check out the automatic aftershock forecasts for the #NevadaEarthquake at earthquake.usgs.gov/earthqua… Indeed, the sequence has been energetic, translating into a roughly 1-in-5 chance of another M>6 quake over the next month.

In 1868, a magnitude 6.8 earthquake struck Hayward, CA - killing 30 people and causing widespread property damage. Shaking was so severe that nearly every building in Hayward was wrecked. (1/4)

Additional pics of liquefaction on Grand Cayman. Notice how the sand eruption was powerful enough to spray up on the cars. Also, see the cavities left behind under the pavement that the cars have sunken into. Now imagine a school or hospital instead of cars.

Something most don't think about w/ respect to earthquakes. Water supply after a major EQ is critical. In quake-prone areas tanks will often have baffles installed to keep water from developing momentum & sloshing out the top. There's also risk of wall collapse from added forces.

Puerto Rico still being jostled by quakes, as per the @USGS aftershock forecast: earthquake.usgs.gov/earthqua… The aftershocks of the several large events appear to be occurring along two intersecting alignments, suggesting multiple main faults involved. ❎marks the spot. How Caribbean

The Ridgecrest earthquakes caused damage to Earth’s crust that could be seen from space. NASA released this psychedelic-looking satellite image of ruptures and displacements not visible to the naked eye latimes.com/local/lanow/la-m…

Eight years ago today, an #earthquake and #tsunami inflicted the world’s costliest disaster on the #Tohoku region of Japan. The #Cascadia subduction zone off the Washington coast puts us at similar risk. Check your risk and what you can do to prepare ➡️bit.ly/2goULZw

Today's #Yellowstone #CalderaChronicles describes the spread of some recent misinformation about our favorite Wyoming volcanic system. Purple monkey dishwasher. volcanoes.usgs.gov/volcanoes…
This spectrogram from a borehole strainmeter near Lake Junction in Yellowstone National Park shows the rate of ground movement over time, but has been misinterpreted as showing gas emissions with depth -- totally incorrect! Just one example of misinformation about Yellowstone data that one can find in the media and on line.
