Sizeable Earthquakes off U.S. and NZ, Flooding in Paraguay
Aleutian Island Quake Triggers Tsunami Warning, None for Quake off New Zealand
On June 23, a magnitude 7.9 earthquake struck off Alaska’s Aleutian Islands (Reuters). The large quake triggered dozens of aftershocks within an hour, with two measuring M6.0 and M5.9 (USGS/NEIC). A tsunami warning for the coastal areas at the western end of the Aleutian island chain, from Nikolski to Attu, was issued by the US National Tsunami Warning Center (NTWC), though later downgraded to an advisory. The tsunami generated was reported by NTWC (Message 6) to have reached a maximum observed height of 0.7 feet at Amchitka, 0.6 feet at Atka, 0.3 feet at Dutch Harbor, and 0.2 feet at Shemya, Adak, Nikolski, and St. Paul Island. “Observed Max Tsunami Height” is defined by NTWC as the “water level above the tide at the time of measurement.”
Earthquake activity was also reported off New Zealand’s Kermadec Islands on June 23 (Reuters).There were no initial reports of damage or tsunami threat from the M7.2 earthquake that struck off Raoul Island, located approximately 800 kilometers from New Zealand’s North Island.
Ongoing Flooding in Paraguay
Heavy rains since early this year have caused the Parana and Paraguay rivers to overflow, affecting thousands of families in the departments of Ñeembucú, Alto Parana, Presidente Hayes and Alto Paraguay, the municipality of Ayolas, and the nation’s capital, Asunción. (ReliefWeb)
As of this report, the flooding has affected over 40,000 families. Roughly 14,000 families have been displaced, the majority of them from Asunción. Though the water level of the Parana river has slowly been decreasing, the Paraguay river is expected to rise to 7 meters (up from its average 1.5 meters) during the first week of July, which may affect an additional 1,000 families in Asunción.
