Security has been tightened throughout the country with officers and soldiers observed on patrol in major cities ahead of anticipated demonstrations against the government called to coincide with independence day.
Midday arrived without any sign of the planned demonstrations.
Residents in several major urban centers noted the day began with unusual quietness, with a large number opting to stay home amid uncertainty over if the demonstrations would proceed.
The demonstrations were called to demand political reforms in the wake of the unrest that followed last October's elections which left an unknown number of people dead.
The authorities have admitted employing force against demonstrators, claiming that certain elements aimed to topple the government.
Correspondents noted on Tuesday streets that were largely deserted in the business hub, Dar es Salaam. This was a stark contrast to the city's typical weekday activity.
Although quiet, the atmosphere remained tense.
Security vehicles were seen driving along major roads and intersections, while officers took up positions at strategic locations, including around important public buildings and facilities.
On social media, activists and campaigners urged followers to remain vigilant, suggesting any demonstrations were unlikely to begin until the afternoon. This communication mirrored previous protest calls in Tanzania, when turnout increased later in the day.
Drivers who went out experienced regular stops at security checkpoints, where police interrogated motorists about their destinations.
The government has not issued specific statements on the increased security or on the scheduled demonstrations.
Tanzanian authorities have banned the planned protests and called off independence anniversary events, advising the public to remain at home.
"With many staying at home the atmosphere is quiet but tense."
The overall situation depicted a country under strain, where the potential for demonstration led to a security clampdown in advance that left conspicuously quiet typically busy cities.
