This article provides a look at earthquakes and what can be done to mitigate their damage. The scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory review the damaging earthquakes over the past few months in Mexico and in other areas and outline what must be done to prepare for these unexpected events.
The article ends with an analysis of current volcanic activity on Hawaii Island:
“This past week, Kilauea Volcano’s summit lava lake level fluctuated with summit inflation and deflation, ranging about 32-39 m (105-128 ft) below the vent rim. On the East Rift Zone, the 61g flow remained active, with lava entering the ocean near Kamokuna and surface breakouts downslope of Pu‘u ‘O‘o. The 61g flows do not pose an immediate threat to nearby communities.”
“Mauna Loa is not erupting. Rates of deformation and seismicity did not change significantly during the past week, but persist above long-term background levels. Small-magnitude earthquakes occurred beneath the summit caldera and upper Southwest Rift Zone, primarily at depths less than 5 km (3 mi), with some deeper events at depths of 5-13 km (3-8 mi). GPS measurements continue to show deformation related to inflation of a magma reservoir beneath the summit and upper Southwest Rift Zone. No significant changes in volcanic gas emissions were measured.”
“No earthquakes were reported felt on the Island of Hawaii during the past week.”
