Little understood galactic and sub-sea activities continue to pose threats to millions around the world. On Oct. 8, a magnitude 6.0 earthquake struck northeast of the capital of the Pacific island nation of Tonga, the U.S. Geological Survey said. The quake was located 137 miles east-northeast of Nuku'Alofa at a depth of 12.2 miles, the survey said.

During the next 48 hours, two other strong earthquakes were also registered. A strong earthquake with a preliminary magnitude of 5.6 jolted northeastern Japan on Monday, Oct. 10, public broadcaster NHK said. The quake, at 11:46 a.m., was felt in Tokyo. Another of magnitude 4.7 rattled the city of Christchurch, New Zealand. New Zealand and Japan, both situated on the Rim of Fire, are experiencing strong earthquakes on almost a daily basis. The magnitude 4.7 quake struck Christchurch after 8:30 p.m. Oct. 9, and there were no initial reports of significant damage or injuries. The country's Prime Minister John Key was in Christchurch watching a televised All Blacks rugby match with other fans at the time. The game was being played in Auckland.

In addition, the Jakarta Post reported increasing activity at six volcanoes across Indonesia, citing the National Disaster Management Agency (BNPB) report. BNPB spokesperson Sutopo Purwo Nugroho said yesterday that the volcanoes on high alert were Mount Tambora in West Nusa Tenggara; Anak Ranakan in East Nusa Tenggara; Papandayan in West Java; Karangetang and Lokon in North Sulawesi; and Anak Krakatau in the Sunda Strait.

These volcanoes are on alert level III, which means all volcanic parameters show that activities could develop into an eruption or disaster, he told the Jakarta Post via text message. He said that Anak Krakatau was producing 5,000 tremors per day. A 2 kilometer exclusion zone has been set up around the volcano. Sutopo said the volcanoes were being monitored 24 hours a day
