Nanao (Japan (AP/PTI): A series of powerful earthquakes hit western Japan, leaving at least eight people dead and damaging buildings, vehicles and boats, with officials warning people in some areas on Tuesday to stay away from their homes because of a risk of more strong quakes.

Aftershocks continued to shake Ishikawa prefecture and nearby areas a day after a magnitude 7.6 temblor slammed the area on Monday afternoon.

Eight people were confirmed dead in Wajima city, officials said. Seven others were seriously injured, while damage to homes was so great that it could not immediately be assessed, they said.

Kyodo news agency reported at least 13 deaths had been confirmed.

"Saving lives is our priority and we are fighting a battle against time," Prime Minister Fumio Kishida said Tuesday. "It is critical that people trapped in homes get rescued immediately."

A quake with a preliminary magnitude of 5.6 shook the area as he was speaking.

Japan's military dispatched 1,000 soldiers to the disaster zones to join rescue efforts, Kishida said, stressing they were facing "large-scale damage." Details of damaged homes were still under investigation, he said.

Firefighters continued to battle a fire in Wajima city which reddened the sky with embers and smoke.

Nuclear regulators said several nuclear plants in the region were operating normally. A major quake and tsunami in March 2011 caused three reactors to melt and release large amounts of radiation at a nuclear plant in northeastern Japan.

News videos showed rows of collapsed houses. Some wooden structures were flattened and cars were overturned. Half-sunken ships floated in bays where tsunami waves had rolled in, leaving a muddied coastline.

On Monday, the Japan Meteorological Agency issued a major tsunami warning for Ishikawa and lower-level tsunami warnings or advisories for the rest of the western coast of Japan's main island of Honshu, as well as for the northern island of Hokkaido.

The warning was downgraded several hours later, and all tsunami warnings were lifted as of early Tuesday. Waves measuring more than one meter (3 feet) hit some places.

The agency warned that more major quakes could hit the area over the next few days.

People who were evacuated from their houses huddled in auditoriums, schools and community centers. Bullet trains in the region were halted, but service was being restored in some places. Sections of highways were closed, water pipes burst, and cellphone service was out in some areas.

U.S. President Joe Biden said in a statement that his administration was "ready to provide any necessary assistance for the Japanese people."

Japan is frequently hit by earthquakes because of its location along the "Ring of Fire," an arc of volcanoes and fault lines in the Pacific Basin.

Mangaluru: Kasturba Medical College (KMC) has filed a patent application for “Absorbent Pads” designed to address urinary incontinence among elderly women, a condition that remains largely underreported despite its widespread impact.

Urinary incontinence does not command urgency like a heart attack, nor does it evoke the same collective response as more visible illnesses. However, for those living with it, the burden is constant, intimate, and often isolating.

There is a gradual and often unspoken impact on daily life. It begins with hesitation, declining invitations, avoiding travel, and choosing silence over conversation. Over time, this can lead to withdrawal, where fear of embarrassment starts shaping everyday decisions. For many elderly women, dignity becomes tied to small, often invisible compromises, including limiting outings or adjusting routines.

What makes this condition particularly poignant is not just its prevalence, but its invisibility. It is endured, not expressed. Accepted, not addressed.

It is in this context that the recent innovation assumes importance. The team at KMC, which includes clinicians such as Dr Haroon Hussain, has approached the issue not merely from a technical standpoint but from the perspective of lived experience.

The proposed solution, biodegradable, antimicrobial absorbent pads with improved fluid control and reduced irritation, aims to go beyond basic functionality, addressing comfort, safety, and dignity.

The development also reflects the role of academic institutions in addressing everyday health challenges. When research focuses not only on major diseases but also on conditions that affect quality of life, it reinforces the broader purpose of healthcare.

However, experts note that innovation alone cannot fully address the issue. Urinary incontinence continues to be underreported, often dismissed as an inevitable consequence of ageing. Many women do not seek medical help, not due to a lack of solutions, but because of stigma and discomfort associated with discussing the condition.

This creates a paradox, a widespread issue that is often experienced in isolation.

Medical professionals emphasise that greater awareness and open conversations are essential. Families must learn to speak about such issues without embarrassment. Healthcare providers must create spaces where patients feel heard without judgment.

The significance of this innovation lies not only in its technical aspects but also in what it brings into focus, that even the most private discomforts deserve public attention.

The patent application was filed by a team comprising Dr. Haroon Hussain, Dr. Sameena, Dr. Ritu Raval of Manipal Institute of Technology, Syed Ayaan Hussain Rizvi, and Suzanne Riya Dsouza.
