Global climate change is being felt in many coastal communities of the United States, often as small scale nuisance flooding. According to researchers at the University of California, Irvine, rising sea levels will cause these smaller events to become increasingly frequent in the future and their cumulative effect will be comparable to extreme events such as Hurricane Katrina or Superstorm Sandy.
New early warning systems installed with the support of active community participation help protect communities around Lima from landslides and floods. Improved drainage systems have also been installed in Peru to drain excess water into the river, thereby reducing flood risk.
A new approach may fine-tune estimates of the range of shaking from earthquakes and help define areas of potential damage. The silence from nonreporting zip codes on the crowdsource earthquake monitoring website Did You Feel It (DYFI) is transformed into useful data by assigning each of those zip codes the lowest intensity rating on the modified Mercalli intensity scale.
