Geologic Hazards • Earthquakes • Tsunami • Volcanism • Slope Hazards
Earthquake Safety • You may well experience an earthquake • Earthquakes don’t kill people; Buildings kill people • We will not be in high risk settings • Minor shaking: no hazard • Major or prolonged shaking: Get outside • Avoid buildings and power lines • Trees are well engineered seismically • If inside, get under something sturdy or brace in a doorway.
Tsunamis • Warning Signs • Strong earthquake on coast • Abrupt changes in sea level – up or down • Get to high ground or inland immediately • Do not pass Go, do not collect $200
Volcanism • We will not go anywhere near active volcanoes or known hazardous areas. • If activity occurs, we will evacuate immediately • I am a volcano expert. If you see me running, try to catch up.
Slope Hazards • Landslides due to earthquakes • Mudflows due to heavy rains • Get out of the way • Get off slope if you sense movement • Get away from streams if water level starts to rise
Rips • When waves break parallel to a beach, rips occur
