Taal Volcano in Batangas showed heightened activity anew after at least 10 volcanic quakes around it were recorded in the last 24 hours.
In its 8 a.m. Wednesday bulletin, the Philippine Institute of Volcanology and Seismology (Phivolcs) said the alert level at Taal remains at "1."
"Taal Volcano's status at Alert Level 1 means that a hazardous eruption is not imminent. However, the public is reminded that the Main Crater should be strictly off-limits due to sudden occurrence of steam explosions and accumulation of toxic gases," it said.
Phivolcs said the northern rim of the Volcano's main crater - in the vicinity of Daang Kastila trail - may also be dangerous when increased steam emission is reactivated along existing fissures.
Phivolcs reminded the public that the entire Volcano Island is a Permanent Danger Zone (PDZ), and permanent settlement in the island is strictly not recommended.

The U.S. Geological Survey says a temblor with a magnitude of 3.0 struck early Tuesday about 25 miles northwest of the ghost town of Jeffrey City.
The quake comes almost a week after another minor earthquake struck Wright. A 3.2 magnitude earthquake struck at 10:16 p.m. Thursday. It happened just 7 miles northeast of Wright, about 5 miles underground.
At first the USGS thought it might be a mine blast, but later deemed it a genuine earthquake.
David King, Campbell County's emergency management coordinator, said the county sits on several fault lines which have caused 10 recorded earthquakes since 1967.
Thursday's quake is the county's fourth quake since 2000. Quakes in 2009, 2008 and 2004 all occurred about 17 miles underground away from Gillette at a magnitude of about 2.5.
The county's largest earthquake occurred in September 1984 west of Gillette by the Johnson County line at a magnitude of 5.1. There were two other earthquakes in the county that year - a magnitude 5 and 2.5.
There are no recorded earthquakes in Gillette.

The U.S. Geological Survey reports a quake with a magnitude of 3.1 was detected Tuesday at 4:25 a.m. in rugged, mountainous terrain 29 miles west of Salmon near the former mining town of Cobalt.
The quake was first detected by staff at the Earthquake Studies Office at the Montana Bureau of Mines and Geology. Director Mike Stickney says a 3.1 magnitude is barely enough to cause people to notice and it's not likely the tremor caused any serious damage to the landscape.
Stickney says it's not uncommon for small quakes to jolt the vast, mountainous backcountry north of Salmon and Challis.

Mount St. Helens, Washington - A series of nine small earthquakes shook an area near Mount St. Helens over the weekend.
Seismologists at the University of Washington have been monitoring the quakes.
A 2.6 quake occurred at 2:26 p.m. on Saturday about six miles north of the volcano. Another quake, a 2.5, occurred at 2:44 p.m. in the same area. The depth for both quakes was two miles. Another quake occurred six miles north-northwest at 10:48 p.m. That measured 2.2 and was 2.2 miles deep.
Smaller quakes, ranging from magnitude 1.3 to 2.2, occurred on Sunday.

A shallow earthquake with a magnitude of 3.9 has rattled parts of southern Idaho near the Wyoming and Utah borders.
The United States Geological Survey says the temblor struck Tuesday night about 9 miles southwest of Georgetown.
USGS says the epicenter was less than a mile underground.
Bear Lake County Sheriff's dispatcher Gene Perkins says no reports of damage or injuries were reported. He says he felt his chair "move just a hair" as he was sitting at home at the time of the quake.
