An strong undersea earthquake on Thursday off central Indonesia's Nusa Tenggara island chain sparked panic and prompted a brief tsunami warning, but there were no reports of casualties or major damage.
The quake struck near Sumbawa island at a depth of 19 km (11 miles), Fauzi, head of seismology at Indonesia's meteorological and geophysics agency, told Reuters.
"We have cancelled the warning. The quake had no tsunami potential," Sri Woro, the head of the agency, told Reuters.
Residents in Raba town on Sumbawa island said the quake sparked panic but no damage was reported.

Don't set the holiday picnic table just yet. You might need to clear some snow first.
Britain's astounding April, the warmest on record, has produced an astounding effect in the natural world, with at least 11 species of butterfly making their earliest recorded appearances this spring in what will be seen as the most remarkable demonstration yet of the effects of climate change on Britain's wildlife.
Once the bugs locate prey, they stun it with a bite. "It's much, much worse than a bee or wasp sting," Sites said. "I was bitten in the pad of my little finger, and I felt intense pain all the way to my elbow for a good 30 minutes."
After the prey is stunned, the predatory insects whip a straw-like appendage out and pump toxins into their meal, liquefying it from the inside-out. "After that, they suck out the juice," Sites said.

Victorian Premier Steve Bracks says the proposed $10 billion federal takeover of the Murray-Darling basin is back to square one.
Mr Bracks has written to Prime Minister John Howard rejecting the second draft of the legislation.
He says the Federal Government had indicated it would no longer seek total control of the basin, but the new legislation still demands the states refer all their powers to the Commonwealth.

Tiny amounts of the estrogen used in birth control pills can cause wild fish populations to collapse, according to a new study.
The finding raises concern about even low levels of estrogen in municipal wastewater, said study leader Karen Kidd, a biologist with the Canadian Rivers Institute at the University of New Brunswick.
"Women excrete estrogen naturally, and women on birth control pills also secrete the synthetic estrogen in those pills," she explained.
"And these estrogens, depending on the level of wastewater treatment, may not be completely broken down during sewage treatment, so they get discharged into rivers and streams."
Male fish exposed to the hormone become feminized - they produce the same proteins that female fish do to develop eggs. Some males even develop eggs in their testes.
"It doesn't take a lot of estrogen to feminize male fish and, based on the results of our experiment, to impact fish populations," Kidd said. (Learn more about freshwater pollution.)

Government forecasters called for a busier than normal hurricane season Tuesday.
National Weather Service forecasters said they expect 13 to 17 tropical storms, with seven to 10 of them becoming hurricanes.
The forecast follows that of two other leading storm experts in anticipating a busy season.
The likelihood of above normal hurricane activity is 75 percent, the National Oceanic and Atmospheric Administration said.
"With expectations for an active season, it is critically important that people who live in East and Gulf coastal areas as well as the Caribbean be prepared,'' said Bill Proenza director of the national hurricane center in Miami.
