Tsunami safety On Tuesday, April 17, Scripps Institution of Oceanography will present the 13th annual Revelle Lecture as part of the Scripps Distinguished Lecture Series. Titled “Tsunamis: Are we underestimating the risk?” the lecture will feature Eddie Bernard, scientist emeritus for the National Oceanic and Atmospheric Administration’s (NOAA) Pacific Marine Environmental Laboratory (PMEL) and former director of NOAA’s Pacific Tsunami Warning Center. Presented by the Ocean Studies Board, the lecture will take guests through past devastation and future preparedness for tsunamis. In recent years, tsunamis have wreaked broad devastation, from the 2004 Indian Ocean tsunami, in which hundreds of thousands of people lost their lives, to the destruction in Japan just over a year ago. As a result, countries around the world are addressing the hazards associated with tsunamis. Bernard will describe threats to the United States and how coastal communities can best prepare for a devastating tsunami. The free lecture starts at 4 p.m. at the Robert Paine Scripps Forum for Science, Society and the Environment (Scripps Seaside Forum), 8610 Kennel Way. Get your grunion run on Birch Aquarium is once again inviting the public along for a must-see ocean adventure. From April to early June, locals can observe the mysterious grunion spawn on the beaches of La Jolla. On certain spring nights following high tides, hundreds of the small, silvery fish ride the waves onto shore for a remarkable mating ritual, which only happens in Southern California. While on the beach, female grunion bury themselves in the sand to lay eggs, while males wrap themselves protectively around the females to fertilize the eggs. Both catch a wave to return to sea. Birch Aquarium naturalists will guide participants through an unforgettable night, starting with a presentation on grunion, followed by a rare opportunity to witness grunion eggs hatch. The experience continues with a moonlit beach exploration to witness the grunion run, nature willing. Bring a flashlight and a warm jacket. This month, events will take place on April 8 from 10:45 p.m. to 12:45 a.m. and on April 23 from 10:30 p.m. to 12:30 a.m. The program is $12 per person, ages 6 and up. Ages 6-13 must attend with a paid adult. For more information or to make a reservation, call (858)?534-7336 or visit aquarium.ucsd.edu.
