Tsunami Information and Tropical Storms
The weekly hazard highlights report features natural hazards such as major drought, earthquake, fire, flood, storm, tropical storm, tsunami, and volcano events. For real-time information on current disasters download PDC’s free Disaster Alert mobile app available for your iOS or Android devices today! Also be sure to monitor PDC on Twitter, Facebook, and by accessing the Global Hazards Atlas page. Below we take a closer look at the various tsunami information provided by PDC and monitor Tropical Storm Lorena and Tropical Depression Gabrielle.
To bring you the latest tsunami information worldwide, PDC provides up-to-date information on current tsunami hazards by showing estimated tsunami arrival times. The contours of the Tsunami Travel Time layer show the expected travel time from an earthquake’s epicenter to coastal locations. Tsunami Travel Time is generated each time the Pacific Tsunami Warning Center issues a tsunami message. The tsunami travel time contours in the image above were generated as a result of a 6.8 magnitude earthquake that struck this past week off the coast of Alaska. The information above shows real-time information on current hazards. To examine historic tsunami event information, let’s take a look at other available data below.
Tsunamis are caused by disturbances such as earthquakes, landslides, or volcanic eruptions that displace ocean water. To examine the locations of different events that caused tsunamis in the past, access the Tsunami Events layer. This layer provides information on the date, magnitude, runup, and location of events that generated tsunamis, and covers tsunami events from 49 B.C. through 2012.
Another way to look at historic tsunami information is to turn on the Tsunami Runups layer, this layer gives users locations where tsunami impacts have occurred. Examine details such as date, run-up height in meters, and the number of deaths for historic events in your area.
The information above provides a glimpse of some of the tsunami information provided by PDC, to access more information or to learn how to prepare for a tsunami event visit the tsunami information page. Alternatively, you may type “tsunami” in the search box on the PDC website to access additional relevant sources.
Next, let’s take a look at two tropical storms that PDC is monitoring closely.
Tropical Storm Lorena and Tropical Depression Gabrielle
In the Caribbean, Tropical Depression Gabrielle (as of NHC Advisory 5) is progressing northwest and expected to cross over the Dominican Republic early tomorrow morning bringing two to four inches of rain. Meanwhile over on the pacific side of North America, Tropical Storm Lorena is also moving northwest and is expected to arrive at southern Baja California, Mexico, early Saturday morning. Lorena could strengthen over this period and is expected to produce three to five inches of rain (NHC). PDC will continue to monitor these events to bring you the latest updates.
