ARLX013 Clear Frequencies Requested for Possible Nicaragua
Earthquake Traffic

IARU Region 2 Emergency Coordinator Carlos Alberto Santamaria
Gonzalez, CO2JC, has requested that radio amateurs in Central
America avoid 7098 and 7198 kHz in the wake of an earthquake at 0957
UTC the morning of September 22 in Nicaragua.

The US Geological Survey (USGS) said the offshore magnitude 6.5
earthquake has also affected Belize, Costa Rica, El Salvador,
Guatemala, and Honduras. The earthquake was followed by another 4.0
temblor and other aftershocks of less intensity, as confirmed by
Juan de la Cruz Rodriguez Perez, YN1J, President and National
Emergency Coordinator of the Club de Radio Experimentadores de
Nicaragua (CREN).

CREN is the International Amateur Radio Union (IARU) member-society
for Nicaragua.

The earthquake occurred offshore in the North Pacific some 60 miles
from Chinandega and approximately 52 miles southwest of the resort
town of Jiquilillo, Nicaragua. The USGS said the quake occurred at a
depth of approximately 20 miles.

According to the Nicaraguan Institute for Territorial Studies, the
event was related to the tectonic processes of the collision between
the Cocos and Caribe tectonic plates.

Emergency communicator Juan de la Cruz, YN1J, requested the
frequency protection.

No tsunami warning has been issued and there have been no immediate
reports of damage.

According to the USGS, "Little or no landsliding is expected, but
some landslides could have occurred in highly susceptible areas."
And, "The number of people living near areas that could have
produced landslides in this earthquake is low, but landslide damage
or fatalities are still possible in highly susceptible areas. This
is not a direct estimate of landslide fatalities or losses."
