A FAMILY of TT nationals living in Guatemala say they are scared in the aftermath of Sunday's eruption of the Fuego volcano which has claimed the lives of more than 69 people.
The institute says only 23 of the recovered bodies have been identified so far.
It is feared that the number of victims can rise substantially since 192 people still remain unaccounted for.
Sunday's blast generated pyroclastic flows - fast-moving mixtures of very hot gas and volcanic matter - which descended down the slopes, engulfing communities including El Rodeo and San Miguel Los Lotes.
The explosions billowed ash more than 5,000m (16,000ft) above sea level, with Guatemala's seismology and volcanology institute warning that there is a moderate flow of risky material down the volcano - with the possibility of a strong flow in some areas.
The disaster agency said a little earlier that at least 70 people had died from Sunday's eruption of the volcano west of Guatemala City. It warned civil aviation authorities to closely monitor and take precautions regarding air traffic.
Dozens of people were seen walking along roadsides carrying children or a few belongings beside paralysed traffic in parts of Escuintla township south of the volcano. Rescuers were evacuated from those areas with the new flows Tuesday afternoon.

Among those who have not evacuated were Brian Jordan and his wife, who were hoping the lava spares their Leilani Estates home. It advised residents in communities downwind, including Pahala, Ocean View and Kona, to limit their exposure to gas and ash.
Iyawa, who is also Nigeria's Ambassador to Mexico, and the non-resident ambassador to the Republic of Panama, in a condolence letter, said Buhari considered Guatemala one of Nigeria's most important allies in Central America.
The institute said there was a moderate flow of unsafe volcanic material down the volcano, and warned of the possibility of a strong flow in some areas.
Nigeria has condoled with the Government and People of the Republic of Guatemala over the Fuego volcano tragedy in the country.
No evacuation alert was issued before the volcano erupted on Sunday, said Sergio Cabañas, the director of Guatemala's disaster prevention agency.
Francis sent a telegram of condolence Tuesday, saying he was "profoundly sorry" to learn of the high toll.
Sanchez, the Conred spokesman, said many dogs and cats had been rescued with burns on their paws from the mud and ash, some blinded from the volcanic gases.
The latest activity has been mostly on the far side of the volcano, facing the Pacific coast.
