Earth Changes
At about 1 a.m., the volcano's crater ejected mud and ash more than 500 meters into the air. Ashes traveled hundreds of meters around the national park, rangers reported.
Although the volcano is frequently active, this kind of strong explosion has not been recorded since 2006. Experts said the activity was normal, but they will continue monitoring the volcano.
Poás Volcano National Park will remain open to tourists while experts determine if there is any risk to visitors.
There were reports of tremors even at Hayathnagar in Rangareddy district around the same time. The earth quake monitoring centre at Vijayawada termed the incident as 'very minor' and said there was nothing to worry about. "It's common to experience such tremors when the rocky layers of earth make adjustments within themselves," said RDO S Venkata Rao.
According to information, some houses and structures suffered minor damages due to the tremors in Nalgonda district. However, officials admitted that it was for the first time that the tremors were felt in so many villages almost simultaneously.
So far, those answers are as mysterious as the timing of earthquakes, a question that has baffled humans -- and killed them -- for generations. But recent findings suggest that some linkage exists to increasingly powerful storms.

The first snowfall of winter in Europe has fallen in Russia and Poland, with freezing temperatures being recorded earlier than usual.
Heavy snow fell throughout Poland, in what some are calling an "early winter", leaving three people frozen to death. The snow cut power supplies to about 70,000 in the Warsaw area and caused transport delays across the country. During the night, snow clearing machines were used to make roads drivable and workers spent the evening shoveling snow from pavements.
In Moscow, melting snow resulted in areas of the city, including parks and some of the central squares, becoming waterlogged.
The number of woodland sites in the east of England found to be infected with deadly ash dieback has leapt to more than 20.
The main concentration of cases of ash dieback - which has wiped out swaths of trees in the rest of Europe - are in mature ancient forests in East Anglia, along the coast where easterly winds arrive from Scandinavia. By Friday there were just two confirmed sites, but surveys have now turned up many more, the Forestry Commission said.
"The new cases will have to be confirmed by scientists, but it certainly looks as if there are more than 20 suspicious sites and we will continue to survey, although we really only have a one- or two-week window now to detect new cases before the autumn leaf drop makes it very difficult to see," said Stuart Burgess of the Forestry Commission.
The New Jersey shore is expected to take the brunt of the massive weather front - which forecasters said could be the largest in U.S. history - as Sandy hits near Atlantic City around 2am on Tuesday and churns north, with 50 million people in its path.
The worst of the Category 1 storm, which experts say is accelerating as it moves northwestward, is expected to bring a 'life-threatening' surge of seawater up to 11 feet high, coastal hurricane winds and a barrage of heavy snow in the Appalachian Mountains.
Nine U.S. states have declared states of emergency with the National Guard poised to swoop in, and President Obama has warned the nation to brace itself. 'This is a serious and big storm,' Mr Obama said after a briefing at the federal government's storm response center in Washington. 'We don't yet know where it's going to hit, where we're going to see the biggest impacts.'

Massive waves pounded the beach and the entrances to the boardwalk were flooded and impassable. Three shelters are already reported full as Atlantic Avenue was already flooded with three feet of water at 7 a.m. and it was increasingly impossible to drive. Strong winds battered the boardwalk making it hard to stand. Emergency workers tried to get some of the homeless to leave but a few stubbornly stayed on their benches, at least until the worst of the storm arrives later today.

Utilities and state road workers monitor the situation on Virginia Dare Trail as rain and wind from Hurricane Sandy engulf the beachfront road in Kill Devil Hills, N.C., Sunday, Oct. 28, 2012.
"The time for preparing and talking is about over," Federal Emergency Management Administrator Craig Fugate said Sunday as Hurricane Sandy made its way up the Atlantic on a collision course with two other weather systems that could turn it into one of the most fearsome storms on record in the U.S. "People need to be acting now."
Forecasters said the hurricane could blow ashore Monday night or early Tuesday along the New Jersey coast, then cut across into Pennsylvania and travel up through New York State on Wednesday.
Airlines canceled more than 7,200 flights and Amtrak began suspending train service across the Northeast. New York, Philadelphia, Washington and Baltimore moved to shut down their subways, buses and trains and said schools would be closed on Monday. Boston also called off school. And all non-essential government offices closed in the nation's capital.
The New York Stock Exchange said it will be shut down Monday, including electronic trading. Nasdaq is shutting the Nasdaq Stock Market and other U.S. exchanges and markets it owns, although its exchanges outside the U.S. will operate as scheduled.
