No tsunami threat to Japan after huge volcanic eruption in Indonesia
Mt. Lewotobi erupted at around 2:10 a.m. Japan time and the plume briefly rose to a height of about 19,000 meters, the agency said. Shortly after the eruption, it began assessing the possibility of a tsunami reaching Japan.
Large volcanic eruptions can sometimes trigger tsunamis due to atmospheric pressure waves, but no significant changes in sea level were recorded at tide gauges in Japan or abroad, according to the Japan Meteorological Agency.
Mt. Lewotobi has been highly active, prompting the weather agency to repeatedly investigate possible tsunami impacts since last year. In each case, no effects on Japan were observed.
On Wednesday, meanwhile, the agency issued a tsunami warning for the nation's Pacific coast after a massive earthquake struck off Russia's Kamchatka Peninsula.

Typhoon Bailu Forms in South of Japan; Moving 100 Kilometers East of Hachijojima Island
A tropical depression over the seas south of Japan formed into Typhoon Bailu, or Typhoon No. 10, at around 9 a.m. on Sunday, the Japan Meteorological Agency announced. The typhoon at that time was about 100 kilometers east of Hachijojima Island moving north-northeast at about 30 kph with a central pressure of 996 hectopascals. The maximum wind speed near its center was 18 meters per second, according to the agency.

Japan braces for another dangerously hot day
Another dangerous heatwave is expected to roast much of Japan with highs of 38 degrees Celsius or higher forecast on Sunday. The Japan Meteorological Agency says a high-pressure system is expected to cover wide regions of the country, bringing sunny and hot weather. A daytime high of 39 degrees is forecast for Yamaguchi City. Various locations, from the Kanto-Koshin to Kyushu regions, are expected to have highs of 38 degrees. They include the cities of Kofu, Nagoya, Osaka and Takamatsu, as well as Hiroshima Prefecture's Shobara City and Miyazaki Prefecture's Miyakonojo City. Highs of 37 degrees are possible in Aizuwakamatsu City in Fukushima Prefecture, Maebashi City in Gunma Prefecture, Tsu City in Mie Prefecture and Okayama City. The temperature in Morioka City in Iwate Prefecture, central Tokyo, Hiroshima City and Tottori City is forecast to rise to 36 degrees. Heatstroke alerts have been issued for 38 of Japan's 47 prefectures from Kanto-Koshinetsu to Okinawa Prefecture. Temperatures have reached life-threatening levels of over 40 degrees for four consecutive days through Saturday. Agency officials say the mercury hit 40.1 degrees in Isesaki City in Gunma Prefecture and 40 degrees in Maebashi City, also in Gunma Prefecture, and Akiota Town in Hiroshima Prefecture. They say it is the first time since August 2013 for highs to exceed 40 degrees for four straight days in Japan. People are urged to stay cool by using air conditioners. They are also advised to consume adequate amounts of water and salt, and rest frequently while working outside.

Indonesia's Mount Lewotobi Laki Laki erupts again, spewing giant ash plumes miles away
JAKARTA, Indonesia (AP) -- Mount Lewotobi Laki Laki, one of Indonesia's most active volcanoes, erupted for a second straight day, sending a column of volcanic materials and ash up to 18 kilometers (11 miles) into the sky early Saturday and blanketing villages with debris. No casualties were immediately reported. Another eruption Friday evening had sent clouds of ash up to 10 kilometers (6.2 miles) high and had lit up the night sky with glowing lava and bolts of lightning. The two eruptions happened in a span of less than five hours. Indonesia's Geology Agency recorded an avalanche of searing gas clouds mixed with rocks and lava traveling up to 5 kilometers (3 miles) down the slopes of the mountain. Drone observations showed deep movement of magma, setting off tremors that registered on seismic monitors. Volcanic material, including hot thumb-sized gravel, was thrown up to 8 kilometers (5 miles) from the crater, covering nearby villages and towns with thick volcanic residue, the agency said. It asked residents to be vigilant about heavy rainfall that could trigger lava flows in rivers originating from the volcano. Saturday's eruption was one of Indonesia's largest since 2010 when Mount Merapi, the country's most volatile volcano, erupted on the densely populated island of Java. That eruption killed more than 350 people and forced hundreds of thousands to evacuate. It also came less than a month after a major eruption on July 7 forced the delay or cancelation of dozens of flights at Bali's Ngurah Rai airport, and covered roads and rice fields with thick, gray mud and rocks. Lewotobi Laki Laki, a 1,584-meter (5,197-foot) volcano on the remote island of Flores, has been at the highest alert level since it erupted on June 18, and an exclusion zone has been doubled to a 7-kilometer (4.3-mile) radius as eruptions became more frequent. The Indonesian government has permanently relocated thousands of residents after a series of eruptions there killed nine people and destroyed thousands of homes in November. Indonesia is an archipelago of more than 280 million people with frequent seismic activity. It has 120 active volcanoes and sits along the "Ring of Fire," a horseshoe-shaped series of seismic fault lines encircling the Pacific Basin.
